Answer:
Reaction between an oxygen and a phosphorus will produce oxides of phosphorus.
Explanation:
Reaction between oxygen and phosphorus produces four atoms of phosphorus with five atoms of oxygen. Sometimes it produces two atoms of phosphorus and five atoms of oxygen and sometimes four atoms of phosphorus and six atoms of oxygen. It does so depending upon the availability of oxygen. The size of phosphorus atom interferes with the ability to form a double bonds to the other elements, such as nitrogen, oxygen, etc.
Answer: low pH
Hydronium is H^+ and acids give hydronium ions to water solution.
PH = -log H^+ concentration. The higher the concentration, the lower pH value
Answer:
The sun is heavier than all of the planets, thus having more gravity
Explanation:
Because the sun is heavier, it exerts more gravitational pull towards itself, thus keeping all of the planets in orbit.
Answer:
Krypton.
Explanation:
By Graham's Law:
Rate 1 / Rate 2 = sqrt M2 / sqrt M1
Molecular Mass for Neon is 20.18
so we have:
38 / 77.5 = sqrt 20.18 / sqrt x where x is the unkown gas.
sqrt x = 9.162
x = 83.94.
This gas is Krypton.
