Answer:
O The number of oxygen atoms in the reactants used by this process equals the total number of oxygen atoms in the products.
Explanation:
The statement that best describes how photosynthesis follows the law of conservation of mass is that the number of oxygen atoms in the reactants used by this process is equal to the total number of oxygen atoms in the products.
The equation of photosynthesis reaction is given as:
6CO₂ + 6H₂O → C₆ H₁₂ O₆ + 6O₂
According to the law of conservation of mass, matter is neither created nor destroyed during the course of a chemical reaction.
By the virtue of this, the number of oxygen atom on both sides of the expression must be the same. Also, the number of carbon and hydrogen atoms must also be the same.
An atom cannot be broken down any smaller whereas a compound is made up of atoms and can be broken down into smaller pieces (the individual atoms that make it up)

Assuming the surface on which the box moves is frictionless, the rate at which the box accelerate is equal to 0.5 
.
<u>Given the following data:</u>
- Mass of box = 50 kilogram
To determine the rate at which the box accelerate, assuming the surface on which the box moves is frictionless:
Mathematically, Newton's Second Law of Motion is given by the formula;
Making acceleration the subject of formula, we have:
Substituting the given parameters into the formula, we have;
Acceleration = 0.5

Answer:
Oxygen and Carbon are in the non-metal section. Both are in 2nd period while Carbon is in group 4A and Oxygen is in group 6A.
Oxygen has more valence electrons than carbon. I wish I could give you a more accurate explanation why on paper, but all you need to do is count the electrons on the largest shell.
Here's the orbital notation of Carbon: 1s^2 2s^2 2px^1 py^1
Carbon's largest shell is 2. Count the electrons on shell 2, and you get 4 valence electrons.
Orbital notation of Oxygen: 1s^2 2s^2 2px^2 py^1 pz^1
Oxygen's largest shell is 2. So, like with carbon, count the electrons on the largest shell. You get 6.
There is a way easier way of interpreting this where you do not even have to write the orbital notation. I wish I can explain, but just know the periods and the group numbers.
