Yes. carbon dioxide is deadly and i want to get away from it fast.
Answer:
Partial pressure of Ne = 366 mmHg
Explanation:
In a mixture, the sum of partial pressures for each gas, is the total pressure for the system.
Partial pressure He: 43 mmHg
Partial pressure Ar: 835 mmHg
Partial pressure Xe: 111 mmHg
Partial pressure Ne: ?
Total pressure = 1355 mmHg
43 + 835 + 111 + x = 1355
989 + x = 1355
x = 1355 - 989 → 366
Answer:
Energy enters the biosphere as sunlight. Plants change this energy into chemical energy through the process of photosynthesis. Then, the energy is passed to organisms that eat the plants. Energy and matter are also passed between organisms when they eat one another.

Explanation:
Answer:
40%
Explanation:
We'll begin by obtaining the molar mass of MgO. This is illustrated below:
Molar Mass of MgO = 24 + 16 = 40g/mol
Observing the formula MgO, we have 1 atom of O in it.
The percentage composition by mass of oxygen in MgO is given by:
Mass of O/Molar Mass of MgO x 100
= 16/40 x 100 = 40%
