A 20 L cylinder of gas at 5.6 atm pressure at 35 degrees Celsius is heated to 95 degree Celsius and compared to 23 atm. What is
ella [17]

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

Degger [83]

Answer:

12

Explanation:

pOH = -log(1.0 x 10^-2) = 2

pH = 14 - pOH

pH = 14 - 2 = 12

According to the law of conservation of mass, mass cannot be gained or destroyed in a chemical reaction. Why can’t you simply ad
xxTIMURxx [149]

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).

A 0.01 M aqueous NaOH solution has a hydroxide concentration of ————— M?
MA_775_DIABLO [31]

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
