If 3.91 moles of H2 were used, how many moles of NH3 would be made?
HELP PLEASE ASAP
N + H2 → NH3
balance the equation
2N + 3H2 → 2NH3
3H2 → 2NH3
3 : 2
3.91 ÷ 3 = 1.303 mol
1.3 × 2 = 2.606 mol
What is the mass in grams of 4.8 moles of Calcium Hydroxide?
Answer:
355.2 grams
Explanation:
m = M×n= (40 + 2(16+1))×4.8= 355.2 (g)
Calculate the Keq of the reaction CH4 + O2 ⇌ CO2 + 2H2O, given the following concentrations at equilibrium:
[CH4] = 0.37M [O2] = 0.25M [CO2] = 0.86M [H2O] = 0.44M

i. Write the dissolution reaction of BaF2, including all states. (0.5 points)
BaF2←>Ba2+(aq)+2F-(aq)
ii. Write the expression for Ksp for BaF2. (0.5 points)
iii. Write the Ksp expression as an algebraic equation, using the variable x to represent concentrations. (1 point)
iv. Find the solubility of BaF2 by solving the equation you wrote in part iii. (0.5 points)
Answer:
See Explanation
Explanation:
i) The equation of the dissolution of BF2 is;
BaF2(s)⇄Ba2+(aq)+2F-(aq)
ii) Ksp =[Ba2+] [2F-]^2
iii) Let the concentration/solubility of [Ba2+] and [2F-] be x
Ksp = [x] [2x]^2
Ksp = 4x^3
iv) x =∛Ksp/4

how many atoms are in 1.6g C? Answer in units of atoms.
(no answer choices were given)
Answer:
6.022 ×10(index 23) / 7.5 = 0.8293 ×10(index 23)
Explanation:
molar mass of C = 12gmol
therefore in 12g of C there is one mole or an amount of 6.022 ×10(index 23)
∴12g/6.02210(index 23) ×1.6g

If the sun output of solar radiation increased by 20% how would this impact the temperature of earth's mantle
Answer:
The temperature will not be affected directly
Explanation:
The solar radiation has a direct effect on the outer surface and inner part of the earth but an increase by 20% of the solar radiation will not cause the temperature of the Earth's mantle to increase because the factors that heat up the Earth's mantle are : Friction between core materials that sink into the center of the planet and Heat from decay of radioactive materials

Which of the following setups will correctly convert 36.45 grams of sodium to moles of sodium?
Answer:
D.
Explanation:
To convert from grams of a substance to moles of a substance, you use molar mass as a conversion factor. Sodium's molar mass is 22.99 grams per mole. To cancel out grams, you need to place grams on the bottom and moles on the top.

Explanation:
transmutation occurs during which type of radioactive decay
Explanation:
Transmutation, conversion of one chemical element into another. A transmutation entails a change in the structure of atomic nuclei and hence may be induced by a nuclear reaction (q.v.), such as neutron capture, or occur spontaneously by radioactive decay, such as alpha decay and beta decay (qq. v.).

3.60x10-12 + 3.60x10-11
Answer:
3.60X10^-12 is equal to 0.360X10^-11 (move decimal one place left)
Now you can add 3.60X10^-11 and 0.360X10^-11:
3.60X10^-11 + 0.360X10^-11 = 3.96X10^-11
You're really just adding 3.60 to 0.36 since the "X10^-11" is the same for both.
