 .

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

Answer:

Option A.

2Na + 2H2O —> 2NaOH + H2

Explanation:

To know which option is correct, we shall do a head count of the number of atoms present on both side to see which of them is balanced. This is illustrated below below:

For Option A:

2Na + 2H2O —> 2NaOH + H2

Reactant >>>>>>> Product

2 Na >>>>>>>>>>> 2 Na

4 H >>>>>>>>>>>> 4 H

2 O >>>>>>>>>>>> 2 O

Thus, the above equation is balanced.

For Option B:

2Na + 2H2O —> NaOH + H2

Reactant >>>>>>> Product

2 Na >>>>>>>>>>> 1 Na

4 H >>>>>>>>>>>> 3 H

2 O >>>>>>>>>>>> 1 O

Thus, the above equation is not balanced.

For Option C:

2Na + H2O —> 2NaOH + H2

Reactant >>>>>>> Product

2 Na >>>>>>>>>>> 2 Na

2 H >>>>>>>>>>>> 4 H

1 O >>>>>>>>>>>> 2 O

Thus, the above equation is not balanced.

For Option D:

Na + 2H2O —> NaOH + 2H2

Reactant >>>>>>> Product

1 Na >>>>>>>>>>> 1 Na

4 H >>>>>>>>>>>> 5 H

2 O >>>>>>>>>>>> 1 O

Thus, the above equation is not balanced.

From the illustrations made above, only option A is balanced.

Which elements have the most properties in common with magnesium
Lunna [17]
The group that magnesium is in has all the elements that are alike to it.
Magnesium  is in group 2 which is the alkaline earth metals. So elements similar to it would be calcium, beryllium!

If you pump air into cycle tyre a slight warming effect is noticed at valve stem why
Mashutka [201]

As the air molecules move through the valve they have friction as they hit the walls, and its this friction that causes it to heat up.
