Reaction
Decomposition of Magnesium nitrate into Magnesium oxide, Oxygen, and Nitrogen oxides
2 Mg(NO₃)₂ → 2 MgO + 4 NO₂ + O₂
mol Magnesium nitrate-Mg(NO₃)₂(MW=148,3 g/mol) :
mol ratio Mg(NO₃)₂ : NO₂ = 2 : 4, so mol NO₂ :
mass NO₂(MW=46 g/mol) :
.
Since 1.00 atm is equal to 760 mmHg, the height of the column of mercury which would create pressure equal to 1.00 atm is 760 mm or 76 cm
<h3>What are the units of pressure?</h3>
Pressure is defined as the force acting perpendicularly per unit area of a surface.
The units of pressure include;
- millimetres of mercury, mmHg
- aatmospheres, atm,
- pascals, Pa
- Newtons per square metre, N/m^2
1 atmosphere is equal to 760 mmHg.
Therefore, the height of the column of mercury which would create pressure equal to 1.00 atm is 760 mm or 76 cm

One molecule of glucose has 6 carbon atoms. So if you have three molecules of glucose, simply multiply 3 by 6 carbon atoms. The correct answer is C. 18 Carbon atoms.
The correct answer for the second questions is C. Air. A homogenous mixture is a mixture in which its components are uniformly distributed throughout the mixture. It has a sigle phase.
I would say that it's true
