The organic compound that is <span>used for stored chemical energy and contains carbon, hydrogen, oxygen, and often phosphorous is called lipid.
Lipids are molecules which consist of fats, waxes, and other things and their function is to store energy, and make up cell membranes.

I think the answer is reversible. Reversible reaction is a kind of reaction which can react in both direction at the same time. And when the both side reactions get the same speed, the reaction is at a equilibrium state.
Answer:
The oceans are the very foundation of human life. life itself arose from the oceans. The oceans are vast, covering about 140 million square miles, some covering 72 percent of the earth's surface.
Explanation:
Answer:
Explanation:
Given data:
Mass of sample = 0.673 g
Volume = 250.0 mL (0.25 L)
Temperature = 83°C (273+83= 356 k)
Pressure = 747 torr (747/760 = 0.98 atm)
Gas type = ?
Solution:
PV = nRT
n = PV/RT
n = 0.98 atm× 0.25 L / 0.0821 atm. L/mol.K × 356 k
n = 0.245 / 29.23/mol
n = 0.01 mol
Number of moles = mass/ molar mass
Molar mass = 0.673 g / 0.01 mol
Molar mass = 67.3 g/mol
molar mass of CO2 = 44 g/mol
molar mass of H2 = 2.016 g/mol
molar mass of SO3 = 80.066 g/mol
molar mass of Ar = 40 g/mol
molar mass of Xe = 131.3 g/mol
So non of these gases are present.
