Answer:

It is represented by the symbol K.

Explanation:

  • <em>The different choices:</em>

1. Its value remains constant at different temperatures:

It is wrong because it depends on the T and varies by varying the T.

2. It is a ratio of coefficients of reactants to products:

It is wrong because It is a ratio of coefficients of products to reactants.

3. It is represented by the symbol K:

It is right, since it is represented by the symbol K.

4. Its value is always less than 1:

It is wrong, because it may be equal, less or more than 1 depends on the reaction components.

Answer:

sigma bond

represents two electrons

Explanation:

The bond between hydrogen and oxygen is sigma bond because the bond between hydrogen and oxygen is covalent means sharing of electron takes place between two atoms and we know that sigma bond is also occurs in a covalent bond in which overlapping of atomic orbitals or hybrid orbitals along the bond axis occurs. Both also represent two electrons because both atoms share one electron each so we can say that the two atoms represents two electrons.

7. How many joules of energy do I need to change 2 grams of water from 0°C solid water to 0° liquid water?
Ratling [72]

7. D. 668 joules

8. B. 3 grams

<h3>Further explanation</h3>

Given

2 grams of water

6768 joules of energy

Required

Energy

Mass of water

Solution

The heat to change the phase can be formulated :

Q = m.Lf (melting/freezing)

Q = m.Lv (vaporization/condensation)

Lf=latent heat of fusion

Lv=latent heat of vaporization

7. phase change (ice to water)⇒Heat of fusion water=334 J/g

Q = 2 g x 334 J/g

Q = 668 J

8. phase change(water to vapor)⇒heat of vaporization water=2260 J/g

6768 J = m x 2260 J/g

m = 3 g
