I think that the anserw is B.
Answer:
The gas pressure in both mmHg and torr is 1.00 x10⁻⁴.
Explanation:
The standard atmosphere (1 atm) equals a pressure of 760 mmHg, where mmHg represents the pressure exerted by a column of mercury 1 mm high. <u>The mmHg unit is also called the torr</u>, after the Italian scientist Evangelista Torricelli, who invented the barometer. Thus,
1 torr = 1 mmHg
and
1 atm = 760 mmHg = 760 torr
Therefore, we do the following conversion:
1 atm ------------------- 760 mmHg
1.32x10⁻⁷ atm ------- x= 1.00 x10⁻⁴ mmHg (3 significant digits)
K + 02 ---> K20
4K + O2 ---> 2K2O
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.
I think the answer is reversible. Reversible reaction is a kind of reaction which can react in both direction at the same time. And when the both side reactions get the same speed, the reaction is at a equilibrium state.
