The atomic number is the number of protons in an element or the number of electrons in an element.

Atomic number=number of protons=number of electrons

<span>Atomic number=atomic mass - number of neutrons</span>

Which of these statements would be true if the water molecule was linear instead of bent? Check all that apply.

Katen [24]

If the water molecule was linear instead of bent the water would no longer produce hydrogen bonds.

<u>Explanation:</u>

Yes, If the water molecule was linear instead of bent the water would no longer produce hydrogen bonds.
The water would no longer generate hydrogen bonds.
It will lose its polar features and nearly all of its features will change such as boiling point, water tension and solubility.
It would be more like to gas, rather than liquid.
If the water was in the linear, the water would have all the features and it would produce the hydrogen bonds.

Consider the reaction represented by the equation?2SO2(g) + O2(g) 2SO3(g).?For the system at chemical equilibrium, which of the

rewona [7]

Answer:

b. The amount of SO3(g) decreases and the value for K increases.

Explanation:

Hello,

In this case, for the given reaction:

$2SO_2(g) + O_2(g)\rightleftharpoons 2SO_3(g)$

The change in the stoichiometric coefficient is:

$\Delta \nu=2-2-1=-1$

In such a way, since the reagents have more moles than the products, based on Le Chatelier's principle, if the volume is increased, the side with more moles is favored. In addition, since the formation of reagent is favored, K is diminished based on the law of mass action shown below:

$K=\frac{[SO_3]_{eq}^2}{[SO_2]_{eq}^2[O_2]_{eq}}$
