 .

The whole surroundings has a pressure of one atmosphere. As a result, the pressure at seven-hundred ppm is 700x atm.

  So, we can see that doubling CO₂ will result in a 0.15 pH unit reduce in the pH of rain.

<h3>What is pH answer?</h3>

PH stands for Hydrogen potentials. It refers to the concentration of the hydrogen ions in a solution.    This is the indicator of a solution's acidity or alkalinity. The pH fee on a pH-scale varies from 0 to 14.    The system for calculating pH is pH=−log[H3O+] ∙    pH is the poor logarithm (to base 10) of the molar hydronium ion concentration.    While the pH scale generally runs from zero to 14, it is honestly feasible to calculate a poor pH

When 47.2 J of heat is added to 13.4 g of a liquid, its
leva [86]

Answer: 2.02 J/g°C

Explanation:

To find the heat capacity, we have to manipulate the equation for heat.

q=mCΔT becomes C=q/(mΔT) to find heat capacity. Since we are given our values, we can plug in to find C.

C=\frac{47.2J}{13.4g*1.74°C}

*Please ignore the capital A in front of the °C. In order to have ° in the equaiton, the A pops up.

C=2.02J/g°C

What is the change in boiling point for a 0.615m solution of Mgl2 in water?
ivanzaharov [21]

Answer :  The change in boiling point is, 0.94^oC

Explanation :

Formula used :

\Delta T_b=i\times K_f\times m

where,

\Delta T_b = change in boiling point = ?

i = Van't Hoff factor = 3 (for MgI₂ electrolyte)

K_f = boiling point constant for water = 0.51^oC/m

m = molality  = 0.615 m

Now put all the given values in this formula, we get

\Delta T_b=3\times (0.51^oC/m)\times 0.615m

\Delta T_b=0.94^oC

Therefore, the change in boiling point is, 0.94^oC

Putting rock salt on the roads during a snowstorm is an example of: A. Boiling point elevation B. Vapor pressure raising C. Vapo
kvv77 [185]

Answer:

The correct answer is - D. Freezing point depression.

Explanation:

When rock salt is spread over snow-covered icy roads, it generates a liquid layer over it by melting from the surface thereby lowering or depression in the freezing point below the ice.

Therefore, due to this liquid layer comes into the contact with the ice present on the road and causes other ice to melts. This keeps on decreasing the volume of the ice on the road therefore, rock salts spread on the roads during a snowstorm.
