At a pressure of 505 kPa, the volume of a gas is 12.00 mL. Assuming the temperature remains constant,
Sergio [31]

Answer:

757.5 kPa

Explanation:

Boyle's law states that p1 * v1 = p2 * v2

v1 = 12 mL

v2 = 8 mL

p1 = 505 kPA

p2 = ?

(505)(12) = (p2)(8)

6060 = (p2)(8)

p2 = 757.5

In the following chemical equation, identify the products and reactants and indicate whether or not the equation is balanced. If
aleksandr82 [10.1K]

Answer:

a). The products are C6H12O6 O2 and the reactants are CO2 + H20 + (solar (light) energy)

b). The reaction chemical reaction is balanced from the number of moles of reactants and products

Explanation:

Through photosynthesis green plants, some protistans and some bacteria in the presence of energy from sunlight, produce glucose as well as oxygen from carbon dioxide and water.

It is a chemical reaction taking place in green plant to produce food which it uses to survive.

Photosynthesis requires carbon dioxide, water and solar energy in the leaves of a plant for it to take place.

The equation for photosynthesis is as follows: 6CO2 + 6H20 + (solar (light) energy) → C6H12O6 + 6O2

The products are C6H12O6 O2

and the reactants are CO2 + H20 + (solar (light) energy)

The reaction chemical reaction is balanced from the number of moles of reactants and products
