Answer : The type of reaction described in the sentence is Synthesis or Combination
Explanation :
The balanced equation for the reaction between Phosphorous and Oxygen gas can be written as

From the above equation we can see that there are two different reactants ( P and O₂ ) which are combining with each other to give a single product.
This type of reaction is known as Combination or Synthesis.
A general form of Synthesis reaction is given below.

Here we can conclude that a synthesis / combination reaction is the one where 2 or more reactants combine together to give only one product .
Answer:
I would say the answer is 2
Answer:
c. a proton
Explanation:
A neutron is most equal in mass to a proton.
A neutron is a subatomic particle without any charges on them.
A proton is a subatomic particle with a positive charge.
- the mass of a proton and neutron are the most similar in an atom.
- the mass of a proton is 1.67 x 10⁻²⁷kg
- So also is the mass of a neutron
- the mass of an electron is 9.11 x 10⁻³¹kg
