Explanation:

1. Newton's universal law of gravitation states that every particle in the universe attracts every other particle with a force along a line joining them. The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

2.Bottom because the direction of the gravitational force is always downward toward the center of the Earth ... where the winds are stronger; the mixing tends to reduce the air flow at the higher altitude. (I think its bottom).

What is the percent by volume of alcohol, in a solution containing 24 mL of alcohol dissolved in 90 mL of water?

Dmitry [639]

Answer:

use this formula it will help u .

Explanation:

If 60 ml of ethanol is diluted to a final volume of 400 ml, you create a 35 % ethanol solution.

First, realize that you creating a solution with that contains a polar solute (ethanol) with a polar solvent (water). Remember that "like dissolves like."

If you pour 60 ml of ethanol in a volumetric flask, you add 340 ml of water to dilute this solution to a final volume of 400 ml.

Volumetric flasks are designed to make or dilute solutions to specified final volume.

Since you have 60 ml of ethanol in a total solution of 400 ml, the percentage of ethanol is 35 %.

This result is obtained in the following manner.

ml/400. ml. = .35

.35 x 100% = 35 %

How many moles of NaCl will react completely with 18.5 L F2 gas at 300.0 K and 1.00 atm?

meriva

Hello!

Data:

P (pressure) = 1 atm
V (volume) = 18.5 L
T (temperature) = 300 K
n (number of mols) = ? (in mol)
R (Gas constant) = 0.082 (atm*L/mol*K)

Apply the data to the Clapeyron equation (ideal gas equation), see:
$P*V = n*R*T$

$1*18.5 = n*0.082*300$

$18.5 = 24.6n$

$24.6n = 18.5$

$n = \dfrac{18.5}{24.6}$

$\boxed{\boxed{n \approx 0,752\:mol}}\end{array}}\qquad\checkmark$

Note: If the feedback is to be considered, the closest response is 0.751 mol Nacl
