Answer:
Explanation:
idk why all u guys like trump who do.. hes just a big pain in the a*s.
The container with chalk powder will contain the least amount of water, because it absorbs water, but the containers with honey and cocunut oil will conserve their amount of water, because they will prevent the water evaporation (especially cocunut oil because it will be on the top side of the container).
Answer:
50 mm
4 ft
36 ft
250 cm
1 L
Explanation:
Centimeter to millimeter:
1 cm is equal to 10 mm.
5cm× 10 mm/1 cm
50 mm
Inches to feet conversion:
1 foot is equal to 12 inches.
48 inch × 1 feet /12 inch
4 feet
Yard to Feet conversion:
1 yard is equal to 3 feet.
12 yd × 3 ft / 1 yd
36 ft
Meter to centimeter:
One meter is equal to 100 cm.
2.5 m × 100 cm / 1m
250 cm
Milliliter to Liter:
One L is equal to 1000 mL.
1000 mL = 1 L
Answer:
The concentration after 20 mins is 0.832 M
Explanation:
Zero order rate law is given by;
R = K [A₀]⁰
A zero order reaction, rate is independent of the initial concentration
R = K
Where;
R is the rate of reaction
K is the rate constant = 0.0416 M/min
Since R = K,
Then, R = 0.0416 M/min
After 20 min, the concentration will be;
A = Rt
A = (0.0416 M/min)(20 min)
A = 0.832 M
Therefore, the concentration after 20 mins is 0.832 M
Answer:
4. The combined volume of the Ar atoms is too large to be negligible compared with the total volume of the container.
Explanation:
Deviations from ideality are due to intermolecular forces and to the nonzero volume of the molecules themselves. At infinite volume, the volume of the molecules themselves is negligible compared with the infinite volume the gas occupies.
However, the volume occupied by the gas molecules must be taken into account. Each <u>molecule does occupy a finite, although small, intrinsic volume.</u>
The non-zero volume of the molecules implies that instead of moving in a given volume V they are limited to doing so in a smaller volume. Thus, the molecules will be closer to each other and repulsive forces will dominate, resulting in greater pressure than the one calculated with the ideal gas law, that means, without considering the volume occupied by the molecules.
