Animal cells dont have a cell wall or chloroplasts
The answer is 10 O2, it should de 13 O2.
To know if a reaction is well balanced between the reactants and the products, you have to calculate the number of atoms of each element on both sides of the reaction and to check if they are equal.
*For carbon, on both sides, there are 8 carbon atoms.
*For hydrogen, on both sides there are 20 hydrogen atoms.
*For oxygen, there are 20 oxygen atoms in the reagents and 26 in the products, so it is necessary to increase the number of oxygen in the reactants (without touching the others). For this we put 13 O2 in the reactants instead of 10, to have 26 oxygen atoms on each side.
I do believe the answer is heart because it goes from the blood vessel to the heart.
Answer:
True
Explanation:
A car is designed to utilize fuel as its source of energy. This fuel contains chemicals, which the engine of the car breaks down via combustion to facilitate its functioning. Kinetic energy is a form of mechanical energy produced as a result of motion. A moving object, individual etc uses kinetic energy to do so.
The fuel (gasoline) being supplied into the car's engine makes the car able to move, hence, we can say that the chemical energy present in the fuel is being converted to kinetic energy (observable in the car on motion) with the release of heat by the engine.
