To answer this item, we are to assume that the given gas behaves ideally such that it can follow one of the simplified ideal gas law as written below,
P₁V₁ = P₂V₂
where P is the pressure and V is the volume.
Substituting the known values, while V₂ is unknown,
(100 atm)(10 L) = (1 atm)(V₂)
The value of V₂ is calculated to be equal to 1000 L.
The number of balloons that can be filled is as calculated.
n = (1000 L) / (1 L / balloon)
n = 1000
Answer:
1) first order
2) zero order
3) second order
Explanation:
For a first order reaction, the concentration of the reactants varies exponentially with the rate of reaction. The curve of a first order reaction shows an exponential relationship between the rate of reaction and the change in the concentration of reactants.
For a zero order reaction, the rate of reaction is independent of the concentration of the reactants. So, regardless of the amount of reactant in solution, the rate of reaction is constant.
For a second reaction, the reaction rate increases in direct proportion to the concentration of the reactant in solution.
Answer:

Explanation:
Answer: 8.3 J
Explanation:
We have the following measurement:
Rearranging the units:
Since 1 Newton is 
:
Since 1 Joule is 
:
This is the simplest form possible
<u>Answer:</u> The density of NaCl solution is 3.930 g/mL
<u>Explanation:</u>
We are given:
Mass of cylinder, 
= 21.577 g
Mass of NaCl and cylinder combined, M = 39.664 g
Mass of NaCl, 
= 
To calculate density of a substance, we use the equation:
We are given:
Mass of NaCl = 18.087 g
Volume of NaCl solution = 4.602 mL
Putting values in above equation, we get:
Hence, the density of NaCl solution is 3.930 g/mL
