Answer:What is used up in and stops a chemical reaction? (a) percent yield (b) limiting reactant (c) theoretical yield (d) excess reactant

The correct option is (b)

Explanation:

A chemical reaction is a chemical combination,rearrangement or disintegration of chemical substance(s) (called reactants) to form new chemical substance(s) (called products).

A limiting reactant is the reactant that is totally used up during the course of a reaction. When this reactant is used up, it limits the amount of products formed and eventually stops the chemical reaction.

Explanation:

The limiting reagent is the reactant that is used up completely. This stops the reaction and no further products are made. ... This method is most useful when there are only two reactants. The limiting reagent can also be derived by comparing the amount of products that can be formed from each reactant.

hope this helps have a nice day❤️

According to the conservation of energy is what?

Dominik [7]

Answer:

The correct answer is - C: Energy is neither created nor destroyed, but continually transformed into new forms of energy.

Explanation:

Conservation of energy is the first law of thermodynamics that says that energy is neither generated nor destroyed, can only be transformed from one form to another form continuously. That means no matter what the condition the amount of energy will remain the same, only form will be changed.

For instance, if an electric current will pass through a circuit of a light bulb the electrical energy present in the circuit will transfer into heat and light energy, The amount will remain constant but the one form change to another.

What do you think happens to the matter in a food sample as it is burned?

Alika [10]

Burning and other changes in matter do not destroy matter. The mass of matter is always the same before and after the changes occur. The law of conservation of mass states that matter cannot be created or destroyed
