Nitrogen dioxide is a toxic gas and therefore it is important for a person handling the gas not to inhale these fumes. Also one needs to protect their eyes while working with the gas.
Therefore following safety precautions should be taken to protect against the hazards of nitrogen dioxide
1) One should wear safety goggles to prevent the fumes from entering into the eyes.
2) Protective mask is needed to prevent the inhalation of the fumes.
Concentrated acid can cause burns if it comes in contact with the skin. It may damage the cloths as well. often times concentrated acids emit toxic fumes. Therefore following safety precautions are needed while handling concentrated acid.
1) One should wear safety gloves to prevent the acid from coming in contact with the skin
2) One should wear protective masks to protect themselves from the fumes.
3) One should also wear protective apron to prevent the damage to the cloths.
According to boiling point elevation equation:
Δ T = i Kb m
when ΔT (change in boiling point) = 7.10 C°
and i (van't Hoff factor)= 1
and Kb = 0.520
so, by substitution:
7.10 = 1*0.520 *m
m = 7.1 / 0.52 = 13.65 m
How do you find volume at STP? It can be written as: V = nRT/P. “P” is pressure, “V” is volume, n is the number of moles of a gas, “R” is the molar gas constant and “T” is temperature. Record the molar gas constant “R”.
they are outside the body, because they need to be cooler than the temperature inside the body so sperm can be made. hope this helped you <3
Use stoichiometry to solve this problem. We know that 1.00 mole of CuO is (about) 45g, and we also know that the ratio of CuO to Cu is 1:1, meaning that 1 mole of CuO can be used to produce 1 mole of Cu. Look up the molar mass of Cu on the periodic table to see the answer.
