Which of the following organisms is a tertiary consumer

A reaction that absorbs heat from the surroundings is known as a (n) A) exothermic reaction. B) endothermic reaction. C) displacement reaction. D) decomposition reaction

An ideal gas in a 1.25-gallon container is at a temperature of 125 degrees Celsius and pressure of 2.5 atmospheres. If the gas is oxygen (formula:O2 molecular weight = 32 grams per mole), what is the mass of gas in the container in units of grams?

What is oxidized and what is reduced in this reaction? N2H4 (l) + 2H2O2 (l) → N2 (g) + 4H2O (g) N is reduced and H is oxidized. N is reduced and O is oxidized. N is oxidized and O is reduced. N is oxidized and H is reduced.
