Answer:
A
Explanation:
The law of conservation of mass states that matter can never be created nor destroyed but can be converted from one form to another.
The law of conservation of energy posits that energy cannot be created nor destroyed but can be converted from one form to another.
These laws are the basic laws of existence. Although the laws have been adjusted, they still form the basic principle behind several scientific laws and are responsible for a whole lot of scientific advancements.
While the first law focuses on matter and the content of matter in a body, the second law basically focuses on energy. The second law serves to support the inter convertibility behind the several forms or types of energy.
For example, to do many useful work at home, it is found that energy is converted from its electric form to say heat in an electric iron to press our clothes.
Also, the first law is a fundamental principle useful in the balancing of our chemical equations.
True because they are organically made without any things that include chemicals
Answer:
I believe 1+
Explanation:
when Na loses 1 electron in the outer shell it has 8 valence protons on it's new most outer shell. so now it has 11 protons and 10 electrons. that extra proton (positively charged) adds one extra charge. so +1
Answer:
<u>Solubility of the liquid increases with temperature.</u>
Explanation:
The solubility of the liquid increases with increase in the temperature but there is no effect of the pressure on the solubility of a liquid, whereas, the solubility of gases in liquids increases on increasing the pressure above above the surface of the liquid.
On increasing temperature of a liquid solvent the kinetic energy of the particles of the solvent increases which makes particles to move faster which breaks the particles of the solute more rapidly with more energy.
Also the saturation point of a solvent can be increased by increasing the temperature of it which allows to dissolve more solute in the solvent beyond the saturation point.
