What happens when you add salt to very cold ice?

Answers

Answer 1
When salt is added to ice , it comes into contact with the thin layer of water on the surface of the melting ice. ... This salt water has a lower freezing point, so the temperature of the ice bath can get even colder, thus freezing the ice cream more quickly.

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​

Answers

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?

Answers

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%

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!

Answers

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.

What is true about the formation of a bond?

Answers

Answer:

There is an overall release of energy when bonds form.

Explanation:

There is a general release of energy when bonds form. This energy is called bond energy.

Bond energy is involved in the breakdown or formation of one or more bonds between atoms of a molecule. Atoms bond with each other to achieve their electronic stability, that is, they move from a higher energy situation to a lower energy one. With this we can state that when the bond between atoms is formed, energy is released; therefore, its breakdown depends on energy absorption.

what is atomic radius​

Answers

Explanation:

The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. Three widely used definitions of atomic radius are: Van der Waals radius, ionic radius, and covalent radius


Which quantum number describes the orientation of an orbital within a sublevel?

Answers

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.

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.

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.

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.

Answers

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
