Answer:

19.6 g is the mass of methanol

Explanation:

Density of methanol is 0.787 g/mL.

Density means mass / volume

Methanol density = Methanol mass / Methanol volume.

Let's replace in the formula

0.787 g/mL = Methanol mass / 25 mL

0.787 g/mL . 25 mL = Methanol mass → 19.6 g

Consider the following hypothetical molecular collisions and predict which of the following will form potential products, given
Annette [7]

Answer:

The collision theory is defined as the rate of a reaction is proportional to the rate of reactant collisions.

Explanation:

The reacting species should collide with orientation that allows contract between the atoms that will become bonds together in the product.

The collision occurs with adequate energy  to permit mutual penetration of the reacting species. The two physical factors based on the orientation and energy of collision, the following reaction with carbon monoxide with oxygen is considered.

 2CO(g) + O2(g) → 2CO2 (g)

After collision between the carbon monoxide and oxygen the reaction is

 CO(g) + O2(g) → CO2 (g) + O(g)

Based on the theories of chemical reaction the molecules collide with sufficient amount of energy an activated complex is formed.
