Since HCl04 is a strong acid, being [H+], and a molarity of 2.1 M.
To solve for pH:
pH = -log (M) = -log(2.1M) = -0.32, which is clearly a negative number.
However, to verify the answer, just use the pH meter in determining the pH of the solution.
When an object becomes warm it is an example of exothermic reaction
Answer is: the pressure on the top of the mountain is 0.945 atm.
p₁ = 1.0 atm; pressure at the valley.
T₁ = 25°C = 298.15 K; temperature at the valley.
V₁ = 0.985 L; volume at the valley.
p₂ = ?
T₂ = 22°C = 295.15 K; temperature at the top of the mountain.
V₂ = 1.030 L; volume at the top of the mountain.
Use combined gas law - the volume of amount of gas is proportional to the ratio of its Kelvin temperature and its pressure.
p₁V₁/T₁ = p₂V₂/T₂.
1 atm · 0.985 L ÷ 298.15 K = p₂ · 1.030 L ÷ 295.15 K.
0,0033 atm·L/K = 0.00349p₂.
p₂ = 0.945 atm.
The property of the mineral is luster.
A metallic luster would reflect light the same way as a metal would.
