<em>≈ 0,27 g/cm³</em>
<em>36.5 l = 36.5 dm³ = 36500 cm³</em>
<em>10 kg = 10000 g</em>
<em>d = m/V</em>
<em>= 10000g/36500cm³</em>
<em>≈ 0,27 g/cm³</em>
Climate can determine a lot of things, but it especially determines what kind of plants and animals can live in an area. For example, polar bears need a cold climate. They would be terribly hot and would die quickly in the desert. When climates start to change, animals and plants become endangered.
Winds are generally in the same direction in certain places over the oceans. They have names like the North East Trade winds and Westerlies. These winds are important in climates and were also important to ancient sailing ships which needed the power of the wind to travel.

The answer is sodium sulfate
Chemical reactions are ultimately the reconfiguration of reactants to form products that are in a more energetically favourable state. In this sense, the vast majority of chemical reactions have reactants and products that are at different energy levels.
This means that energy either has to enter or leave the chemical compounds. Some of this energy is in the form of heat, which will cause the system to cool down or heat up.
So, detecting a change in temperature is a good way to find out if a chemical reaction has occurred. Of course, chemical reactions can occur with no detectable change in temperature, and a change in temperature does not necessarily confirm a chemical reaction has occurred.
The Answer is D: Reactor products charge huge batteries.
