i guessed and got it right
Answer:
i dont think i can explain it easy sorry
Explanation:
The first law, also known as Law of Conservation of Energy,Thermal energy is the internal energy of an object due to the kinetic energy states that energy cannot be created or destroyed in an isolated system. | Nuclear energy originates from the splitting of uranium atoms a process called fission. This generates heat to produce steam, which is used by a turbine generator.
then the chemical bonds are broken, | the potential energy is released in the form of kinetic energy or energy of motion and heat or non useable energy. The kinetic energy is used to do work. | Objects have mechanical energy if they are in motion and or if they are at some position relative to a zero potential energyposition for example, a brick held at a vertical position above the ground or zero height position. A moving car possesses mechanical energy due to its motion
The second law of thermodynamics states that the entropy of any isolated system always increases.
<u>Answer:</u>
<em>8.4 ml of water is needed to make a 10 ml of a 2x concentration.</em>
<u>Explanation:</u>
<em>From question,</em>
<em>
</em>
<em>
</em>
<em>
</em>
<em>
</em>
<em>This gives 
</em>
<em>V1 is the available volume of water in the stock solution. </em>
To obtain 10ml of 2x concentration, the volume of water required is: 
of water.
<em>Hence 8.4 ml of water is needed to make a 10 ml of a 2x concentration.</em>
Answer:
What is B amino acids
By biuret test
Explanation:
A Biuret is a compound formed by heating urea to 180° C. When biuret is treated with dilute copper sulfate in alkaline condition, a purple colored compound is formed. This is the basis of biuret test widely used for identification of proteins and amino acids.
