Answer:
The temperature at 760mmHg if the volume is still 4.2 L is 400.862 K
Explanation:
Gay Lussac's law indicates that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. This law can be expressed mathematically as follows:
Having an initial state 1 and a final state 2, the following is true:
In this case:
- P1= 560 mmHg
- T1= 72 F= 295.372 K (being 32 F= 273.15 K)
- P2= 760 mmHg
- T2= ?
Replacing:
Solving:
T2= 400.862 K
Answer:
Nonpolar Solvent. Carbon tetrachloride. CCl4
Explanation:
The other compounds listed are polar;
polar substances are by their nature more soluble in Other polar compounds. NH3 is a gas; so unless it was a very specific compound you needed in ammonia gas, it, being also polar as well as a gas would not be a good choice for this question.

Problem Details
The element europium exists in nature as two isotopes: 151Eu has a mass of 150.9196 amu, and 153Eu has a mass of 152.9209 amu. The average atomic mass of europium is 151.96 amu. Calculate the relative abundance of the two europium isotopes.
answer:
151Eu = 48%, 153Eu = 52%
We know that C has a formal charge of +4 while each O element
has a formal charge of -2, therefore the formal charge of X is:
X + 2 – 2 * 3 = 0
X + 2 – 6 = 0
X = 4
<span>So X has a group number of 4.</span>
