Answer:
a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction.
Explanation:
<h2>
Answer:C</h2>
Explanation:
A chemical equation is a equation that describes a corresponding chemical reaction.
A chemical reaction is generally written as
→
refer to all the reactants involved in the chemical reaction.
Reactants are usually written on the left hand side of the chemical equation.
refer to all the products formed in the chemical reaction.
products are usually written on the right hand side of the chemical equation.
In the given reaction,
,
are written on the right side of the equation.
So,, are the products.
The answer is 365 grams because you need to subtract 411 by 46.
Answer:
C- A proton has about the same mass as a neutron .
Explanation:
In an atom such as a carbon atom, the masses of the proton and neutrons are the same.
The mass of the electrons is very negligible.
- Protons are the positively charged particles in an atom
- Neutrons do not carry any charges
- Both protons and neutrons have similar masses.
- They contribute the bulk of the mass of the atom.
- The electrons carry negative charges and they have negligible masses.
The mass of protons and neutrons are similar.
C. a chemical reaction occurred when the two liquids were mixed
