Sorry for the sloppy writing I tried my best.

If you can't read the words in my photo it says

Evaporation

condensation precipitation and runoff

definition of these words

evaporation: The process of turning liquid into vapor

Condensation:water which collects as droplets on a cold surface when humid air is in contact with

Precipitation: the action or process of precipitating a substance from a solution

runoff: liquid, especially water or rainwater, that flows off or drains away

I hope this is helpful

Vaselesa [24]

<h2>A wind turbine generating electricity involves electromagnetic energy. thermal energy. solar energy. mechanical energy. chemical energy. nuclear energy.</h2><h2>ans: electromagnetic energy, thermal energy, solar energy, and mechanical energy.</h2>

Explanation:

Wind mill

It consist of shaft pole and blades that can rotate .

It converts wind energy into electrical energy .

The shaft of wind mill is connected to shaft of armature of generator .

When the fast moving wind rotates the blades of windmill its shaft rotates, armature rotates hence electricity is produced which is further used for various purposes .

Advantage of using wing energy

it is natural renewable resource

It is eco friendly

Disadvantage :

1. It cant be established everywhere

2. It requires large area

3. It is an expensive project

4. Wind dosen't blow all the time so win energy cant be produced every time

5. Minimum speed of wind required is 15km per hour .

So, the wind turbine generating electricity involves mechanical energy of wing and blades .

How much heat is required to decompose 25.5 grams of NaHCO3? 2NaHCO3(s) + 129 kJ 2Na2CO3(s) + H2O(

Vaselesa [24]

To determine the heat required in order to decompose a certain amount of a substance, we need information on the heat needed to decompose one mole of the substance. This value are readily available online and other sources. For this reaction, the heat needed is 129 kJ per 2 mol of NaHCO3. We calculate as follows:

129 KJ / 2 mol NaHCO3 (1 mol / 84.01 g ) (25.5 g NaHCO3 ) = 19.58 kJ of heat is needed.
