Answer:
B
Explanation:
Hook's law describe the elasticity of something
Answer:
<h3>The answer is 6.86 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 0.94 mL
density = 7.3 g/mL
We have
mass = 7.3 × 0.94 = 6.862
We have the final answer as
<h3>6.86 g</h3>
Hope this helps you
Explanation:
As we know that chloride ion is halogen. So it has seven valence electrons in its valence shell. Hence it gains one electron from others during chemical reaction to be stable. So Chloride ion have a negative charge of -1.

We have two laws that cannot be violated. The conservation of mass and the conservation of energy.
The only reason why the beaker with the products has less mass than what you could expect is because part of the products are gases that escapes from the beaker.
Regarding the energy, the lower energy of the products is due to the release of heat during the chemical reaction.
