Baking soda has a ph of 9. any # that has less than 7 as a ph is acid, any number that has a ph of 7 is neutral, and any number with a ph greater than seven is a base. so baking soda is not an acid but a base.
a chemical dye whose color is affected by acidic and basic solutions is an acid base indicator
The amount of coal burnt each year to produce 8.53 × 10¹⁶ Joule of energy is 2.3 x 10¹² gram.
<h3>
What is Combustion?</h3>
Burning of coal in the presence of air is called combustion.
As according to the given question,
A coal-burning power plant generates 8.53 × 10¹⁶ Joule of energy in a year.
1 gram of coal yields generates 36 kilo joule (36000 Joule) energy.
Hence, to generate 8.53 × 10¹⁶ Joule of energy in a year, the weight of carbon burnt will be ;
= 1/36000 x 8.53 × 10¹⁶
= 2.3 x 10¹² gram

<span>The water alone can perform chemical weathering with the aid of other chemicals which usually form acids that breaks the internal composition of the material. Hot & cold climates usually cause the flaking the outer layers of a rock (thermal expansion) but it belongs to physical weathering.
However, Physical and chemical weathering work together to disintegrate the rock more easier.
I can't specify a climate well because chemical weathering doesn't involve climate too much.
