Answer:0.477 g/ml
Explanation:
Density=(40.14-33.79)/13.3 ml
Density=6.35/13.3
Density=0.477 g/ml
Answer:
Sulfur Dioxide
Explanation:
Sulfur dioxide is the chemical that, when released by factories using fossil fuels, combines with the atmosphere and can produce acid raid.
The enthalpy of formation of CF
is -678.82 kJ/mol.
<h3>What is enthalpy ?</h3>
A thermodynamic system's enthalpy H is calculated by multiplying its internal energy by the product of its pressure and volume. In the equation H = U + pV, U stands for internal energy, p for pressure, and V for system volume; pV is also frequently referred to as the pressure energy P.
The amount of heat in a system under constant pressure is measured as enthalpy (H). Chemists frequently gauge how the enthalpy of chemical systems changes when reactants transform into products. The enthalpy change, which is the same thing as the heat that is absorbed or released by a process at constant pressure, is denoted by the letter H.

Mutation affect a species ability to survive and reproduce. Mutations can expand the life span of a species by keeping them hidden from predators which would also increase reproduction. If exposed to other wildlife, those numbers could decrease.
Answer:
16.84 g
Explanation:
Assuming that the ethanol is free of water
the number of moles of ethanol to generate 500 KJ = 500 / 1368 = 0.3655 mol
molar mass of ethanol = 46.07 g/mol
mass of ethanol needed = 46.07 × 0.3655 = 16.84 g
