As per the question, the mass of the nitrogen gas m = 22.25 gram.
The latent heat of vaporization of nitrogen = 199.0 j/g
As per the question, the nitrogen gas will condense. During condensation, the nitrogen gas will lose or release heat equal to its latent heat.
Hence, the heat released by nitrogen gas Q = ml = 22.25 × 199.0 J = 4427.75 J.
Hence, the amount of heat released will be 4427.75 J.
<h3>How can you figure out how much heat is in each gram?</h3>
The formula: can be utilized to determine energy. Q = mc ∆T. In the equation, Q stands for energy expressed in joules or calories, m for mass expressed in grams, c for specific heat, and T for temperature change, which is the difference between the final temperature and the initial temperature. Water has a specific heat of 1 calorie/gram °C.

Answer:
It would produce ethane (CH₃CH₃)
Explanation:
Ethylmagnesium bromide (CH₃CH₂MgBr) is a Grignard's reagent.
It is a highly reactive substance, and as any alkylmagnesium bromide
(R-CH₂MgBr) it reacts with water to produce an alkane (R-CH₃). R stands for any carbon structure bonded to that functional group.
x=3
Use the pythagorean theorem:
a^2 + b^2 = c^2
4^2 + x^2 = 5^2
16 + x^2 = 25
x^2 = 25-16
x^2 = 9
√x^2 = √9
x = 3
Answer:
Half life of phosphorous-32 = 14 days
Explanation:
Given data:
Total mass of phosphorous-32 = 2.0 g
After 42 days mass left = 0.25 g
Half life of phosphorous-32 = ?
Solution:
First of all we will calculate the number of half lives passed.
At time zero = 2.0 g
At first half life = 2.0 g/2 = 1.0 g
At 2nd half life = 1.0 g/2 = 0.5 g
At 3rd half life = 0.5 g/2 = 0.25 g
Half life:
Half life = T elapsed / half lives
Half life = 42 days/ 3
Half life = 14 days
Answer:
3. The reaction will shift to the left.
Explanation:
Hello,
In this case, since we have a heterogeneous equilibrium, and the given equilibrium constant is given in terms of concentration, the law of mass action takes the following form:
![K=\frac{[HCl]^2}{[CaCl_2]}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BHCl%5D%5E2%7D%7B%5BCaCl_2%5D%7D)
Clearly, just the hydrochloric acid and the calcium chloride participate in the equilibrium as they are the only aqueous species. Nonetheless, the given concentrations are not defining the equilibrium, therefore, one computes the reaction quotient in order to predict what would the system do to reach equilibrium as shown below.
![Q=\frac{[HCl]^2}{[CaCl_2]}=\frac{ 30.2^2 }{0.652 }=1398.8](https://tex.z-dn.net/?f=Q%3D%5Cfrac%7B%5BHCl%5D%5E2%7D%7B%5BCaCl_2%5D%7D%3D%5Cfrac%7B%2030.2%5E2%20%7D%7B0.652%20%7D%3D1398.8)
Thus, since Q>K, the reaction will shift leftwards, favoring the formation of reactants, therefore, answer is 3. The reaction will shift to the left.
Best regards.
