The temperature of the gas sample is 813 K.
<u>Explanation:</u>
We have to use the ideal gas equation to find the temperature of the gas sample.
The ideal gas equation is PV = nRT
Pressure, P = 429 mm Hg = 0.56 atm
Volume, V = 560 mL = 0.56 L
R = gas constant = 0.08205 L atm mol⁻¹K⁻¹
Mass = 0.211 g
Molar mass of carbon di oxide = 44.01 g / mol
Moles, n = 
= 0.0047 mol
Now, we have to plugin the above values in the above equation, we will get the temperature as,
T = 
= 813 K
So the temperature of the gas sample is 813 K.
Answer:
Great question, here are a few! (╯°▽°)╯ ┻━┻
Explanation:
1. Atmosphere, The first difference between the Earth and space is the atmosphere.
2. radiation (high level of dangerous particles)!
3. gravity (weightlessness in space)
Answer: the density of the rock
55.91g/ml
Explanation:
The density of the rock after it had being placed in the cylinder of water so the calculation should look like this:
Volume of water substract the mass of the rock:
And that is 142.5 ml - 86.59g =
Answer 55.91 g/ml
So the density of the rock is 55.91g/ml
Answer:
Cupric oxide, or copper (II) oxide,
Explanation:
Correct me if im wrong tnx:<
Answer:
1. b
2. a
Explanation:
1. The density of an object represents the mass per unit volume of the object. A density of 0.45 g/mL means that 1 mL of the object weighs 0.45 g, 1.000 g/mL means 1 mL weighs 1 g, etc.
<u>A density of 35,885 g/mL means that 1 mL of the object weighs 35,885 g. This is a ridiculously high amount of weight for an object with a volume of 1 mL and seems not reasonable. It is highly unlikely that such a substance exists in nature.</u>
2. <u>Considering the fact that only rock would sink in water of all the substances from a - d, it thus means that rock would have the greatest density.</u> Oil, oxygen, and ice will all float on water, meaning that they are less dense than water.
