Test tubes, spot and/or well plate will be used to combine substances in bottles and form a reaction is referred to a true statement.
<h3>What is a Chemical reaction?</h3>
This is the reaction which involves substances known as reactants combining new substances which are referred to as products. This is usually done in the laboratory and equipment and tools such as test tubes, thermometer etc are used.
Test tubes, spot and/or well plate are often used to combine substances in bottles and form a reaction which must be handled with care to ensure it doesn't spill.
This is therefore the reason why the option true was chosen as the most appropriate choice.

Answer:
Water is polar covalent while isoporopanol is covalent
Explanation:
Water contains polar covalent bonds. Water has a high dipole moment and thus dissolves ionic substances easily such as sodium chloride. Water is also a good electrolyte. Water is not volatile. Water molecules are held together by hydrogen bonds. Isopropanol is a covalent compound. It is non polar and suitable for dissolving non polar substances such as campohor. It is volatile but dissolves in water due the the -OH group present in the molecule.
<span>How many electrons are needed to equal the mass of a proton?
</span>
The correct answer is that you need 1836 electron to equal the mass of a proton. This means that a proton is equals to 1836 electron or 1 = 1836. This is the answer to your question. I hope this answer helped you.
Answer:
“A” since liquid has to above 32F
Answer:
it's O2 since the oxygen has 6 valence electrons and it can make 2 covalent bonds
