Answer:
How many grams of CCL4 were formed? 116.9 g
How many grams of Cl2 reacted with the CH4? 243.8 g
Explanation:
First we need to know the molar mass for every element or compound in the reaction:

Now we proceed to calculate the amount of moles produced, per product:

To calculate the mass of chlorine we just need to make a mass balance:

Answer:Specific heat capacity at Constant volume of Nitrogen =742.32JKg.K
Explanation:
The Specific heat capacity at Constant volume of an ideal gas is given as
c =Cv / M
Cv= Constant volue of gas
M= Molar mass
But First, we determine the Constant volume, Cv which is given as
Cv = 5/2R since Nitrogen is a diatomic gas, N2 where R= 8.314Jmol.k
= 5/2 x 8.314Jmol.K
=20.785Jmol.K
Specific heat capacity at Constant volume, c
c= Cv/M
M=molar mass = 28.0 g/mol.
changing to kg/mol =28/1000= 0.028kg/mol
Therefore c =20.785Jmol.K/0.028kg/mol
=742.32JKg.K
Answer: option B.olive oil.Explanation.The general rule of thumb when you analyze the ability of a solvent to dissolve a solute is that lke dissolves like.
That means:
1) polar solvents dissolve ionic or polar solutes
2) Non-polar solvents dissolve non-polar solutes
3) Non-polar solvents do not dissolve polar and ionic solutes
4) Polar solvents do not dissolve non-polar solutes.
There are exceptions, but the rule is applicable in here.
<span>
A. table salt: it is NaCl, a ionic compound, so the water which is a polar solvent will dissolve the table salt.
B. Olive oil: the oils are non-polar organic compounds, so it will not be dissolved in a polar solvent.
C. Vinegar: vinegar is acetic acid, which is a polar organic compound, so it will be dissolved in water.
D. Sugar: sugar (sucrose) is a polar organic compound, so it will get dissovled in water.</span>
Answer:
The change in the Gibbs function of reaction on going from crust to core, dG=291442.4 J/mol
Explanation:
dG=vdp-sdT
Where T is the temperature .
P is the pressure.
S is entropy
V= 1cm3 =10-6 m3
P= 3*10∧6 atm = 3*10∧11 pa
The temperature at the center of the earth, Tc = 4*103 °C. : The temperature at the sufrace (crust) of the earth, Ts =298K.
Subistuting the values
dG = (10-6 *(3*1011-105) - (2.1(4373-298))
dG=291442.4 J/mol.
Answer:
Explanation:
The two carbon atoms would be different. These different carbon isotopes are called isotopes. Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass number due to the difference in the number of neutrons in their various nuclei.
Carbon for example has 3 known isotopes which are:
¹²₆C ¹³₆C ¹⁴₆C
These isotopes have different places in nature where they can be found. Some can occur together naturally.
Isotopes have the same chemical properties because they share similar electronic configuration.
