Which material is likely to slow the<br> flow of electric charges the most? Explain.
AlladinOne [14]

Explanation:

Atoms of metals do not hold their electrons to themselves. Instead they allow them to float around them delocalised. This is important because it is this characteristic that allows metals to be good conductors of electricity since electrons are free to move around to carry a charge.

How many liters of oxygen are in 8.32 moles of oxygen at STP
Jlenok [28]

Answer:

186 Liters at STP conditions

Explanation:

1 mole of any gas at STP conditions occupies 22.4 Liters.

Therefore, 8.32 moles O₂(g) = 8.32 moles x 22.4Liters/mole = 186 Liters (3 sig.figs.)

Molarity of a salt water solution of "0.47" moles of NaCl dissolved in a volume of 0.25L
asambeis [7]

Answer:

1.88 M

Explanation:

The following data were obtained from the question:

Mole of NaCl = 0.47 mole

Volume of solution = 0.25L

Molarity =?

Molarity is defined as the mole of solute per unit litre of the solution. It can represented mathematically as:

Molarity = mole /Volume

Using the above formula, the molarity of the salt water solution can be obtained as follow:

Molarity = 0.47/0.25

Molarity = 1.88 M

A scientist wants to react a barium chloride salt with an acid. to speed up the reaction, the scientist crushes the barium chlor
In-s [12.5K]

Out of the following given choices;

A. increasing the pH of the salt.

B. increasing the surface area of the salt.

C. increasing the pressure of the salt.

<span>D. increasing the temperature of the salt.</span>

 

The answer is B. When a substance is reduced to smaller sizes, its surface area to volume ratio increases. Therefore crushing barium salts to smaller particles increase the surface area on which it reacts with the acid. This consequently increases the rate of speed of the reaction.
