Answer:
Increase
Explanation:
Boyle's law states volume and pressure have an inverse relationship.

Hello!
the atomic mass of one atom of hydrogen is equal to 1.00784 in atomic mass units
one atomic mass unit is equal to 3.6609e-27 pounds
which means one atom of hydrogen is equal to 3.9478732e-27 pounds
I hope this helps, and have a nice day!
Answer:
41264 g of CO₂
Explanation:
Combustion reaction is:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
1 mol of propane react to 5 moles of oxygen in order to proudce 3 moles of carbon dioxide and 4 moles of water.
In a combustion reaction, our reactant reacts to oxygen and the products are always CO₂ and water.
We have the volume of propane but we need moles of it, so we need to apply density.
Density = mass / volume so mass = density . volume.
Density of propane is: 493 g/L
Mass of propane is 493 g/L . 27.9L = 13754.7 g
We convert mass to moles: 13754.7 g . 1 mol/ 44g = 312.6 moles
According to reaction, 1 mol of propane can produce 3 moles of CO₂
Our 312.6 moles will produce 312.6 . 3 = 937.8 moles
We convert moles to mass: 937.8 mol . 44 g/mol = 41264 g
The answer to this is to prevent dilution of the base, which may affect the results. I think that is right.
Answer:
This is a basic solution
Explanation:
To be able to provide a succint description of this solution, from the given parameters we can deduce the pH of the solution.
Given parameters:
Concentration of OH⁻ = 1 x 10⁻⁴M
Solution
We knonw that pOH = -log₁₀[OH⁻]
pOH = -log₁₀ 0.0001 = - (-4) = 4
For an aqeous solution:
pH + pOH = 14
pH = 14 - 4 = 10
The pH of the solution has been derieved to be 10
This is a basic solution
