Answer:
OH
Explanation:
Hydroxide is a diatomic anion with chemical formula OH⁻.
Answer:
The molar amount of gas.
Explanation:
According to the ideal gas law,
PV = nRT
P = pressure of gas
V = volume of gas
n = number of moles of gas
R = ideal gas constant
T= temperature of gas
When pressure, volume and temperature of gas is known the molar amount of gas can be determine by using above formula.
For example:
P = 1.2 atm
R = 0.0821 atm. L.mol⁻¹ .k⁻¹
T = 293 K
V = 2 L
n = ?
Solution:
PV = nRT
1.2 atm × 2L= n × 0.0821 atm. L.mol⁻¹ .k⁻¹ × 293 K
n = 1.2 atm × 2L / 0.0821 atm. L.mol⁻¹ .k⁻¹ × 293 K
n = 0.1 mol
Answer:
8 moles SO₂
Explanation:
To find the moles SO₂, you need to multiply the given value by the mole-to-mole ratio. This ratio, between O₂ and SO₂, is made up of the coefficients from the balanced equation.
2 H₂S + 3 O₂ -----> 2 SO₂ + 2 H₂O
12 moles O₂ 2 moles SO₂
-------------------- x ---------------------- = 8 moles SO₂
3 moles O₂
