Given that CO2 is produced by cellular respiration, the amount of CO2 in the atmosphere remain relatively constant because CO2 in the atmosphere is also being used by plants to produce not only oxygen but also to produce carbohydrates through the process of photosynthesis.
Answer:
As per Dalton's law of Partial pressure,
The total pressure of a mixture of gases is equal to sum of partial pressure of individual components of the mixture.
So, P=P_H+P_N+P_WP=P
H
+P
N
+P
W
\implies 864\ mm=220\ mm+410\ mm+P_W\implies⟹864 mm=220 mm+410 mm+P
W
⟹ P_W=864-630=234P
W
=864−630=234 mm of Hg.

Answer:
Molar mass of P₂O₅ = 141.948 g/mol which is approximately 142 g/mol.
Explanation:
Molar mass of AlCl₃
Molar mass = 26.982 + 35.5 × 3 = 133.32 g/mol
Molar mass of BaCl₂
Molar mass = 137.33 + 35.5 × 2 = 208.33 g/mol
Molar mass of MgCl₂
Molar mass = 24.305 + 35.5×2 = 95.305 g/mol
Molar mass of P₂O₅
Molar mass = 30.974×2 + 16× 5 = 141.948 g/mol
Hey there:
1 cm³ = 1 mL
D = m / V
7.25 = 12.9 / V
V = 12.9 / 7.25
V = 1.779 cm³
