Answer:
Combination or synthesis
Explanation:
The reaction given below:
C + O₂ → CO₂
The reaction above is termed a synthesis or combination reaction because two substances are combining to give a product.
- A synthesis reaction involves the formation of a single product from two or more reactants.
- The driving force for such reaction is the large and negative heat of formation of the product.
PV=nRT will give you the answer I think. I haven’t worked with a certain unit in that problem
Answer:
use coefficients and subscripts to determine how many atoms are in a compound. If there is no subscript or coefficient, assume it is 1. If there is a coefficient, multiply it with the subscripts. For counting cations and anions, determine first which is the anion and cation (anion = nonmetal, cation = metal), then count the number of that ion.
Example:
NaCl
one atom of Na, one atom of Cl. Since Na is a metal, it is a cation. Cl is a nonmetal, so it is an anion.
2CaCl2
2 atoms of Ca, 4 atoms of Cl. There are 2 cations, since Na is a metal, and 4 anions since Cl is a nonmetal
