Elena-2011 [213]

Answer:

4 M

Explanation:

Molarity can be represented by the following ratio:

Molarity = moles / volume (L)

Since you have been given both the mass and volume, you can plug the values into the equation and solve for molarity.

Molarity = moles / volumes

Molarity = 2.0 moles / 0.50 L

Molarity = 4 M

Fill in the blanks below using vocabulary terms-reactants, products, limiting reactant, excess reactant.
slamgirl [31]

Answer:

The vocabulary terms are in the correct order.  

Explanation:

The substances that undergo chang are called <em>reactants</em>. They are what create the products. Reactants are on the left side of the equation while the products are on the right side of the equation. The new substances are called <em>products</em>. In other words, what is produced? The products are produced. The reactant that will be used up first is called a <em>limiting reactant</em>. Why? Because it is what limits the reaction. It determines how much products can be made. The reactant that is left over then, is called the <em>excess reactant.</em> That is what is left in excess and does <u>not</u> determine how much product is made.

GIVING THE BRAINLIEST
Allushta [10]

The correct answer is A. Charging by friction

Explanation

When someone rubs a comb with their hair when they are combing it and the hair sticks to the comb occurs a phenomenon called electrization, in which a neutral body becomes charged or loses an electrical charge (electrons). One way that electrization occurs is through the rubbing of two neutral bodies which causes one to be positively charged and the other negatively causing them to attract each other by magnetism. Therefore, the correct answer is A. Charging by friction
