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.
<span>Answer: The 1 kg of water will reach the lowest temperature

Both of the objects is water so their specific heat should be same. The heat removed from the 2kg of water which is 2 times of mass than the 1kg water. Since the heat removed, both of their temperatures will drops. But 2kg water temperature drops will be half of 1kg water.
Sandblasted: More smooth because all the rough edges are "blasted" away. And slightly smaller because of the loss of the edges.
Non-Sandblasted: Not smooth; rough.
50.00ml*(10^-3L/ml)*(3.91moles/L) = 0.196 mol
A cohesive force is best described as the attraction between two liquid molecules. Cohesive forces are the inter-molecular forces between similar molecules, which cause a tendency in liquids to resist separation. For example a water drop is composed of water molecules that like to stick together
