Answer:
5.8 L
Step-by-step explanation:
This looks like a case where we can use the <em>Combined Gas Law</em> to calculate the temperature.
p₁V₁/T₁ = p₂V₂/T₂ Multiply both sides by T₂
p₁V₁T₂/T₁ = p₂V₂ Divide each side by V₂
V₂ = V₁ × p₁/p₂ × T₂/T₁
=====
<em>Data</em>:
p₁ = 5.6 atm
V₁ = 20 L
T₁ = 35 °C = 308.15 K
p₂ = 23 atm
V₂ = ?
T₂ = 95 °C = 368.15 K
=====
<em>Calculation:
</em>
V₂ = 20 × 5.6/23 × 368.15/308.15
V₂ = 20 × 0.243 × 1.19
V₂ = 5.8 L
Answer:
12
Explanation:
pOH = -log(1.0 x 10^-2) = 2
pH = 14 - pOH
pH = 14 - 2 = 12
Explanation:
The law of conservation of mass states that mass is conserved which also means that it cannot be created or destroyed within the isolated system.
We can add the mass of the reactant and can be equal to the mass of the product. But in some cases, it will not work like:
If reactants are not in the mole ratio, there will be a limiting reagent.
If a gas is one of reactants or products.
Radioactive decay and nuclear reactions(fission or fusion).
Answer:
Has a hydroxide concentration of 0.01M
Explanation:
When NaOH dissociates, it gives 1mol Na+ and 1mol OH- this multiplies the concentration value and we get 0.01×1= 0.01M
