g At the start of an experiment, there are 0.200 mol of reactant and 0 mol of product in the reaction vessel. After 25 min, 0.111 mol of reactant (CH3NC) remain. There are mol of product (CH3CN) in the reaction vessel. At the start of an experiment, there are 0.200 of reactant and 0 of product in the reaction vessel. After 25 , 0.111 of reactant remain. There are of product in the reaction vessel. 0.022 0.089 0.311 0.111 0.200

b. 0.089

Explanation: The Law of Conservation of Mass states that when in a chemical or physical change, the products' mass of a chemical reaction will equal to the mass of the reactants' mass or in other words, mass cannot be created or destroyed.

The same can be said to moles, since, they are also measures of mass.

In the reaction:

initially there were 0.200 mol of reactant. After 25 min, there are 0.111 mol left.

This means that 0.089 mol of reactant "transformed" into product.

Therefore, in the reaction vessel, there are 0.089 mol of product.

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
