A nuclear reaction, such as those which occur in a nuclear power plant, can be classified as what
type of reaction?
solar
chemical
exothermic
endothermic

Answers

Answer 1
Nuclear reactions are NOT chemical reactions. A chemical reaction occurs when different elements recombinate to form new compounds. A nuclear reaction occurs when elements literally decay or fuse into new elements. Generally, nuclear fusion is exothermic while nuclear fission is endothermic. Because fission is used in nuclear reactors, I believe the answer would be D, endothermic

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.

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

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.

what is the solution to the equation below rounded to the correct number of significant figures? 4700 L - 281.4 = _____ L

Answers

Answer:4400

I went over this problem multiple times and I finally found the soultion

The concept of significant figures are mainly used by scientist and engineer to know the significance of digits in a measurement. Therefore, 4400L is the solution to the equation rounded to the correct number of significant figures.

What is significant figures?

Significant figures are the figures that indicate the degree of accuracy of a value. It tells about the precision of a value. It gives an idea about the digits that are necessary to indicate the experimental value.

Rules for counting significant figures are:

Number between 1 to 9 is always significant

Zeroes after a number has got no significance

Zeroes before a number has got no significance

Zeroes between number has got significance

4700 L - 281.4 =4400L

These models show the electron structures of two different nonmetal elements. Element 1 at left has a purple circle at center with 2 concentric black lines around it. The first line has 2 small green balls on it. The second line has 8 small green balls on it. Element 2 at right has a purple center with 5 concentric circles around it, with the first circle innermost. The first circle has 2 small green balls on it, and the second circle has 8 small green balls on it. The third circle has 18 small green balls on it, and the fourth circle has 18 small green balls on it. The fifth circle has 6 small green balls on it. Which element is likely more reactive, and why?

Answers

Answer:

Element 2

Explanation:

If we look at the model stated for element 1, it is clear that element 1 must be a noble gas. It has eight electrons in its outermost shell this implies that it has already attained a complete octet of electrons and is reluctant towards chemical reaction.

The second element belongs to group 16 since it has six electrons on its outermost shell. It is certainly more reactive than element 1 which is a noble gas.

Answer: D

Element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

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.

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%

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

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.
