Answer:
D
Explanation:
gas are well separated with no regular arrangement and spreaded all over. liquid are close together with no regular arrangement and slightly spreaded. solid are tightly packed, usually in a regular pattern and not spreaded at all.
Planet, solar system, galaxy, universe
Answer:
w = 164.62 g
Explanation:
molarity of a solution is given as -
Molarity (M) = ( w / m ) / V ( in L)
where ,
m = molecular mass ,
w = given mass ,
V = volume of solution ,
From the question ,
M = 500 mM = 0.5 M
( since , 1 mM = 1 / 100 M)
As we know , the molecular mass of potassium ferricyanide = 329.24 g/ mol
V = vol.of solution = 1 L
w = ?
<u>To find the value of w , using the above formula , and putting the respected values , </u>
Molarity (M) = ( w / m ) / V ( in L)
0.5 = ( w / 329.24 ) / 1 L
w = 164.62 g
An sample of an unknown metal was found in a laboratory. Determining the density of the sample can help identify what type of metal is present in the sample. The sample was determined to have a mass of 27.20 g when placed on a scale. When dropped in water, it increased the volume of the water by 3.46 mL. What is the density of the sample of metal?
Use appropriate SIG FIGS in the answer.
Answer:
The particles' kinetic energy is increased, allowing the gas to expand. When a gas is heated the volume will increase when gas is increased....
