I will give brainliest for the correct answer 675.0 mL of oxygen are collected over water at 20.0 °C and a total pressure of 764.0 mm of mercury. What is the volume (in mL) of dry oxygen at 55.0 °C and 817.0 mmHg pressure?

Ase your answer to this question on the information below. hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant. the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen. chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product. nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.

The difference between the atomic number of an element and the element’s atomic mass is the number of ions.

What mass of natural gas (ch4) must you burn to emit 276 kj of heat?
