A theory is a proposed explanation for an observation
Answer:
0.55 atm
Explanation:
First of all, we need to calculate the number of moles corresponding to 1.00 g of carbon dioxide. This is given by

where
m = 1.00 g is the mass of the gas
Mm = 44.0 g/mol is the molar mass of the gas
Substituting,

Now we can find the pressure of the gas by using the ideal gas law:

where
p is the gas pressure
V = 1.00 L is the volume
n = 0.0227 mol is the number of moles
R = 0.082 L/(atm K mol) is the gas constant
T = 25.0 C + 273 = 298 K is the temperature of the gas
Solving the formula for p, we find

Km is the biggest measure in width (even if there are bigger measures like Mm, Gm, Tm).
1 Km = 1000 m, 100000 cm and 1000000 mm
Answer:
C. slightly basic
Explanation:
0-7 = acidic
7 = neutral
7-14 = basic
- Since the pH is just over 7, the answer would be slightly basic.

Answer:
44,901 kilo Joule heat is released when
grams of ammonia is produced.
Explanation:
Moles of ammonia gas produced :

According to reaction, when 2 moles of ammonia are produced 9.18 kilo joules of energy is also released.
So, When 978.235 moles of ammonia gas is produced the energy released will be:

(negative sign indicates that energy is released as heat)
44,901 kilo Joule heat is released when
grams of ammonia is produced.
