Answer:Atomic mass is the mass of an atom in atomic mass units (amu)
Atomic mass
• atomic mass (sometimes called atomic weight) is the mass of the atom in atomic mass units (amu). (from periodic table)
o One atomic mass unit is defined as a mass exactly equal to one-twelfth the mass of one carbon-12 atom. Carbon-12 is the carbon isotope that has six protons and six neutrons. Setting the atomic mass of carbon-12 at 12 amu provides the standard for measuring the atomic mass of the other elements.
o For example, experiments have shown that, on average, a hydrogen atom
Theorists try to find ways to explain human behavior in rational ways. It seems irrational to break rules, if we want to maintain social order. We are largely constrained by the rules and obliged to behave in a particular way or to avoid certain behaviors. What motivates people to break social rules? Do you think powerful and famous people tend to break more rules? Is it worth breaking these rules? No Response(s) Be the first to respond to the Discussion topic!
Answer:
See explanation
Explanation:
According to Burgess (1996); 'We don't break rules because it 'doesn't feel right' to do so. Some elements of personality can determine whether we will break rules or not, particularly when the moral/social-conventional distinction is taken into consideration'.
If an individual has the urge to behave in a manner that transgresses social rules, personality characteristics now come into play here. Personality traits determines whether the individual considers him/herself as bound by the rules. Some people will follow the rules absolutely while some only follow rules that they consider important, a small proportion will not follow any rule that prevents them from achieving their set objectives.
Famous people become carried away with affluence and position and tend to break more rules since they believe that they will always get away with it because of whom they are.
Irrespective of the circumstances, it is never worth it to break a rule. We always have to see ourselves as bound by rules as part of our social responsibility.

Once upon a time, Walter the water molecule was traveling around Linda's blood. He was enjoying moving around wherever he wanted. One day, Walter decided to visit some cells. He traveled in and out of the cells as he pleased. Walter decided that he liked the cells so much that he wanted to stay inside and rest in the vacuole. However, as the day went on, Walter felt a change happening around him. Linda had eaten some VERY salty popcorn. Walter LOVED Sally the salt molecule and felt a magnetic attraction to her. The closer the salt came to the cell, the quicker Walter's love for Sally pulled him out of the cell and towards the salt.
Answer:
This story that is related to the movement of water in relation to the amount of solute seeks to explain the process of OSMOSIS in a very interesting way.
Explanation:
The OSMOSIS process is a process where water diffuses from a compartment with fewer solutes to one with higher solutes, that is why the osmotic intention is to balance the concentrations and molarities between both compartments, this is called osmotic balance.
For this to happen, a highly water-permeable barrier is needed.
combined aggregation of minerals
Answer:
Rocks
Explanation:
The combined aggregation of minerals are called rocks. There are three types of rocks Igneous Rocks, sedimentary rock, and metamorphic rocks.
Rocks are formed due to the repetitive, orderly, geometrical internal arrangement of minerals. Minerals undergo several processes such as weathering, crystallization, erosion, and sedimentation to form rocks.
Hence, the combined aggregation of minerals is called rocks.

Which quantum number describes the orientation of an orbital within a sublevel?
Explanation:
Each orbital within a particular sublevel is distinguished by its value of ml. This quantum number may be more aptly named the orbital orientation quantum number. In each energy sublevel (designated by l) there are 2l+1 possible independent orientations of the electron cloud.
Answer:
[tex]m_l-magnetic[/tex]
Explanation:
The principal energy level, n, tells us which shell it is in and the total energy of the electron.
The angular momentum (azimuthal), l, tells us which sublevel/subshells the electron is in.
The magnetic, m sub l, tells us the orientation the electron is spinning.

What is the specific heat of a metal if the temperature of a 12.5 g sample increases from 19.5 C to 33.6 C when it absorbs 37.7 J of heat.
Answer:
0.213 J/g°C
Explanation:
To calculate specific heat of the metal, the formula is used:
Q = m × c × ∆T
Where Q = amount of heat
m = mass
c = specific heat
∆T = change in temperature
According to this question, Q = 37.7 J, m= 12.5 g, initial temperature= 19.5 °C, final temperature = 33.6°C, c=?
Q = m × c × ∆T
37.7 = 12.5 × c × (33.6-19.5)
37.7 = 12.5c × 14.1
37.7 = 176.25c
c = 37.7/176.25
c = 0.2139
Hence, the specific heat of the metal is 0.213 J/g°C

Insoluble substances can dissolve in all solvents
True or false
Answer:
Not all substances dissolve in all solvents
Explanation:
In chemistry, a common rule for determining if a solvent will dissolve a given solute is "like dissolves like." Solvents composed of polar molecules, such as water, dissolve other polar molecules, such as table salt, while nonpolar solvents, such as gasoline, dissolve nonpolar substances such as wax. Some substances are strong enough to not dissolve.
A piece of metal that has a density of 5.2 g/cm3 and a mass of 100 g was placed in a full jar of water. How many mL of water was spilled out of the jar? Note: one cm^3 = one mL
Answer:
100g / (5.2g/cm3)
= 100g / (5.2g / 1cm3)
= 100g x 1cm3 / 5.2 g
= 19.2 cm3
Since 1 cm3 = 1 ml, your answer is 19.2 ml.
The given density and mass of the metallic piece can be used to estimate the volume of the substance. The metal with a mass of 100 gm and a density of 5.2 g/cm³ has a volume of 19.23 ml.
What is the relation between density and volume?The density of the substance has been given by the ratio of mass to the volume of the substance in g/cm³ or g/mL. It shows the packaging of the molecules in the substances and has been in inverse relation to the volume.
The mass being constant and an increase in volume decreases the density of the substance and vice versa. The volume can be calculated as:
Volume = mass ÷ density
Given,
Density of the metal (ρ) = 5.2g/cm³
Mass of the metal piece (m) = 100g
Volume = V
Substituting the values above as:
ρ = m ÷ V
V = m ÷ ρ
V = 100 ÷ 5.2
= 19.23 mL
Therefore, 19.23 mL is the volume of water that spilled out of the jar.

The boiling of soy oil determined by a student in the laboratory turned out to be 319.5 oC. The accepted value of this melting point is 300 oC. What is the percent error in this reading?
Answer:
Percent error = 6.5%
Explanation:
Given data:
Measured value = 319.5°C
Accepted value = 300°C
Percent error = ?
Solution:
Formula:
Percent error = measured value - actual value / actual value × 100
Now we will put the values in formula.
Percent error = 319.5°C - 300°C/300°C × 100
Percent error = 19.5 °C /300°C × 100
Percent error = 0.065× 100
Percent error = 6.5%

What is the significance of an electronegativity difference of 1.7 between 2
atoms?
O A. It tells which atoms form positive ions and which atoms form
negative ions.
OB. It represents the boundary between what is considered to be an
ionic or a covalent bond.
C. It determines if the 2 atoms will react to form a molecule.
D. It identifies which metal atoms will join together to form metallic
bonds
Am
B. It represents the boundary between what is considered to be an ionic or a covalent bond.
Further explanationElectronegativity is the ability of atoms to attract electrons, especially in covalent bonds (sharing of electron pairs)
In a periodic system, electronegativity increases in a group, from bottom to top, and in a period from left to right.
From this difference in electronegativity, we can determine the ionic compound, polar or non-polar
Pauling determined the electronegativity scale (based on bond energies), between 0.7 - 4 (Fluorine has the highest number of electronegativities: 4)
Polar covalent compounds have a large electronegativity difference, while nonpolar compounds have a small electronegativity difference.
We can use the difference in electronegativity between the 2 bonded atoms to determine their polarity
<0.5: covalent non polar 0.5- 1.7: covalent polar > 1.7 : ionExample
H₂OH = 2.1
O = 3.5
H₂O = 3.5-2.1 = 1.4 >> polar
O₂= 3.5-3.5 = 0 >> non polar

2. In a well-known movie, Raiders of the Lost Ark, there is a famous scene in which the hero tries to outwit the designers of a trap by replacing a gold statue with a bag of sand of about the same volume.
a) Knowing that the density of gold is 19.3 g/mL and sand is 3.1 g/mL, does this seem like a scientifically reasonable plan? Why or why not?
b) In the movie, the hero grabs the gold statue with one hand and appears to handle it quite easily. Given that the volume of the statue appears to be about 1 L, find the mass of the statue.
Answer:
I cant answer B, but I can answer A, and I don't think it is a scientifically reasonable plan.
Explanation:
The bag of sand weighs less than the gold statue, and yes the bag of sand seems like it would keep the trap from activating, but you would scientifically have to put something that was the same weight as the gold statue on the pedestal that the statue is on.
