Explanation:
Answer:
0.31 mole
Explanation:
The following data were obtained from the question:
Mass of SF6 = 45.0 g
Number of mole of SF6 =..?
Next, we shall determine the molar mass of SF6.
This can be obtained as follow:
Molar mass of SF6 = 32 + (19×6)
Molar mass of SF6 = 32 + 114
Molar mass of SF6 = 146 g/mol
Finally, we shall determine the number of mole in 45 g of SF6 as follow:
Molar mass of SF6 = 146 g/mol
Mass of SF6 = 45.0 g
Number of mole of SF6 =..?
Number of mole = mass /Molar mass
Number of mole of SF6 = 45 /146
Number of mole of SF6 = 0.31 mol
Therefore, 0.31 mol is present in 45 g of SF6.
Answer:
Role of photosynthesis
It's not oxygen production. The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet's living systems are powered by this process.
Explanation:
Answer:
Mass = 3.84 g
Explanation:
Given data:
Mass of hydrogen sulfide = 2.7 g
Mass of oxygen required = ?
Solution:
Chemical equation:
2H₂S + 3O₂ → 2H₂O + 2SO₂
Number of moles of hydrogen sulfide:
Number of moles = mass/ molar mass
Number of moles = 2.7 g / 34 g/mol
Number of moles = 0.08 mol
Now we will compare the moles of hydrogen sulfide with oxygen.
H₂S : O₂
2 : 3
0.08 : 3/2 ×0.08 = 0.12 mol
Mass of oxygen;
Mass = number of moles × molar mass
Mass = 0.12 mol × 32 g/mol
Mass = 3.84 g
Answer:
N2 (g) + 3 H2 (g) -> 2 NH3 (g)
Explanation:
First, write the reactants on the left and the products on the right side. Also, add the states of matter after the reactants and products. Note, nitrogen gas is written as N2 and hydrogen gas is written as H2, not N or H.
N2 (g) + H2 (g) -> NH3 (g)
Next, balance the equation! Since there are two nitrogens on the left, add a two to the product NH3. Now there are 6 hydrogens on the right side. To balance that, add a 3 to the H2.
N2 (g) + 3 H2 (g) -> 2 NH3 (g)
Double checking, there are 2 nitrogens and 6 hydrogens on each side.
Success!
