Explanation:
This is the only question that can have a definite answer and not an opinionated response
Answer:
The equation to this question is unclear. The clear equation is:
CH4 + 2O2 → CO2 + 2H2O
Please find the number of atoms of each element on the reactant and product side below.
Explanation:
An atom is the smallest indivisible part of an element. The atom retains the chemical properties of the chemical element. In order to ensure that a chemical reaction between molecules and compounds is BALANCED, the number of atoms of each element that makes up the molecule/compound must be the same on both the reactants and products side.
In this case, the chemical reaction involves:
CH4 + 2O2 → CO2 + 2H2O
1. Carbon atom (C):
Reactants side = 1 atom
Products side = 1 atom
2. Oxygen atom (O):
Reactants side = 4 atoms
Products side = 4 atoms
3. Hydrogen atom (H):
Reactants side = 4 atoms
Products side = 4 atoms
Answer:
breed a has an average of 9 pounds
breed b has an average of 12.125 or 12 (rounded) pounds
Factors you may describe could be, food sources, environment, and climate could have changes in the characteristics of different breeds.
Having controlled factors, having 2 baby rabbits of the same breeds and monitoring the same food and water, observations and data can be collected, done multiple times data can be complied and used to theorize

Answer:
<u><em>True</em></u>
Explanation:
<u><em>Most gymnosperms have reproductive structures called cones. Male cones produce pollen. Female cones contain at least one ovule. An ovule is a structure that contains an egg cell. After being fertilized, the ovule develops into a seed.</em></u>
