Answer: 4.10 liters
Explanation:
Given that:
initial volume of gas V1 = 3.0L
initial temperature of gas T1 = 273K
new volume V2 = ?
new temperature T2 = 373K
Since, only volume and temperature are involved, apply the formula for Charle's law
V1/T1 = V2/T2
3.0L/273K = V2/373K
To get the value of Z, cross multiply
3.0L x 373K = 273K x V2
1119 = 273V2
Divide both sides by 273
1119/273 = 273V2/273
4.10L = V2
Thus, the new volume is 4.10 liters
Answer:
7.35 - 7.45
Explanation:
The pH scale ranges from 0 (strongly acidic) to 14 (strongly basic or alkaline). A pH of 7.0, in the middle of this scale, is neutral. Blood is normally slightly basic, with a normal pH range of about 7.35 to 7.45. Usually, the body maintains the pH of blood close to 7.40.

The mass of ethanol (alcohol) = 538.016 g
<h3>Further explanation</h3>
Given
Reaction
C₁₂H₂₂O₁₁(aq)+H₂O(I) = CH₃CH₂OH(aq)+CO₂(g)
1 kg of sugar = 1000 g
Required
The mass of ethanol
Solution
Balanced equation
C₁₂H₂₂O₁₁(aq)+H₂O(I) = 4CH₃CH₂OH(aq)+4CO₂(g)
mol of sugar (MW = 12.12+22.1+11.16=342 g/mol) :
mol = mass : MW
mol = 1000 g : 342 g/mol
mol = 2.924
From the equation, mol ratio of C₁₂H₂₂O₁₁ : CH₃CH₂OH = 1 : 4, so mol ethanol =
= 4 x mol sugar
= 4 x 2.924
= 11.696
Mass of ethanol(MW=46 g/mol) :
mass = mol x MW
mass = 11.696 x 46
mass = 538.016 g
It seems that you have missed the necessary details for us to answer this question, so I had to look for it. Anyway, here is the answer. If the US <span>adopted and maintained a policy of minimal control of co2 emissions, the level that we would expect its emissions to be in 2020 is that WE CAN'T TELL FROM THIS DATA. Hope this helps.</span>
Answer: <u>It is, as all stars are, a hot ball of gas made up mostly of Hydrogen. The Sun is so hot that most of the gas is actually plasma, the fourth state of matter. ... As we heat up liquid, the liquid turns to gas. Gas is the third state of matter</u>
