Question

A student carries out a chemical reaction that produces a brown powder. How should the student measure the amount of product formed?
Measure the amount of time it takes for the reaction to happen.
Remove the product from the beaker and use a scale to find its mass.
Measure the length of the powder across the bottom of the beaker.
Record the change in temperature of the beaker.

Answer 1

Answer:

B

Explanation:

The best way to find out the amount of a substance, especially if you know what it is, is to measure its mass. If the substance is homogenous (even all the way through), then you can determine some other properties of it, such as its volume and number of moles, just by measuring the mass. Hope this helps!

Answer 2

The amount of product formed in the chemical reaction can be measured by weighing machine.

What is Chemical reaction?

A chemical reaction is a process that leads to the chemical transformation.

What is Product?

Chemical reactions are usually characterized by a chemical change, and they yield one or more products.

What is reactant?

The substance (or substances) initially involved in a chemical reaction are called reactants.

What is weighing machine?

Weighing machine is a measuring instrument for weighing. It shows amount of mass.

The best way to measure the amount of product is to remove the product from the beaker and use a scale to find its mass.
