A scientist monitors the reaction between two gases in a closed container. What would happen to the rate of the reaction of the scientist increases the temperature in the container? (2 points)
O
The rate would increase because higher temperature would increase the number of collisions.
The rate would decrease because the particles are unable to achieve the correct orientation.
O
The rate would decrease because the space available for the reactions would decrease.
The rate would increase because the average speed of the reactant particles would decrease.

Explanation:

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
