Answer:
solid substance formed during liquid solution, is known as precipitate. For example: in the reaction of silver nitrate and sodium chloride, a precipitate of silver chloride is formed which is white in colour. Precipitation can be of any colour like white, yellow, black.
Answer:
174 K
Explanation:
To answer this question we will use the PV=nRT formula, where:
We <u>input the data</u> given by the problem:
- 1.072 atm * 20.0 L = 1.50 mol * 0.082atm·L·mol⁻¹·K⁻¹ * T
And <u>solve for T</u>:
Meaning the correct answer is the fourth option, 174 K.
Answer:
it will affect the mass by changing in pressure will affect the volume (and therefore density) of gases, but will not noticeably affect the volume (or density) of solids and liquids. For gases: An increase in pressure leads to a decrease in volume and an increase in density. A decrease in pressure leads to an increase in volume and an decrease in density.
Explanation:
The answer is the first one because it’s a compound of two words separate when you say it :) hope this helps !
Answer:941.3mL
Explanation:
V1 = 752mL
T1 = 25°C = 25 +273 = 298K
T2 = 100°C = 100 +273 = 373K
V2 =?
V1/T1 = V2 /T2
752/298 = V2/373
V2 = (752/298) x 373 = 941.3
V2 = 941.3mL
