What form of energy is needed to make photosynthesis and respiration possible?
chemical energy
Is dense a physical or chemical property?
Density is a physical property.
What is the 2nd most dense of all the 118 chemical elements?
IRIDIUM
What is the green chemical neede for photosynthesis?
The green chemical needed for photosynthesis is chlorophyll. It is responsible for capturing light energy from the sun and converting it into chemical energy that the plant can use for growth and development.
What substance lowers the energy needed to start a chemical reaction?
A substance that lowers the energy needed to start a chemical reaction is a catalyst.
What form of energy is needed to make photosynthesis and respiration possible?
chemical energy
What respresents the chemical reaction needed to make a compound?
A chemical equation represents the chemical reaction needed to make a compound. It shows the reactants on the left side and the products on the right side, with an arrow in between to indicate the direction of the reaction. The equation also includes coefficients to balance the number of atoms on both sides.
What is rarefacting?
A state of minimum density and pressure The act of making something less dense, or refining it
Is dense a physical or chemical property?

If 16 ounces of a chemical solution in 5 gallon of water equal 500 ppm how many ounces of chemical are needed to make one gallon?
To calculate the amount of chemical needed per gallon, first determine the total amount of chemical in the 5 gallons of water. Since 16 ounces in 5 gallons equal 500 ppm, you can set up a proportion: (16 ounces/5 gallons) = (x ounces/1 gallon). Solve for x to find out how many ounces of chemical are needed per gallon.
What is the Os chemical symbol for?
The chemical symbol for Osmium is Os. It is a hard and dense transition metal known for its high density and resistance to corrosion. Osmium is commonly used in alloys to make fountain pen tips, instrument pivots, and electrical contacts.
