Answer:
What is the empirical formula of the compound?
Explanation:
When the relative masses of elements in a hydrocarbon are given, it is possible to use this information to obtain the empirical formula by dividing the given masses of each element by the relative atomic masses of the element. The lowest ratio is now used to divide through to obtain the empirical formula of the compound.
The empirical formula only shows that ratio of atoms of each element present in the compound. From the information provided, the empirical formula of the compound is CH2. Hence the answer.
Answer:
Explanation:
Hello.
In this case, given the formula:
Whereas E is the energy, h the Planck's constant and u the frequency of the photon. Thus, solving for it, we obtain:
Or also:
Best regards.
Pressure of the gas P1 = 30.7 kpa
When it doubled P2 = 61.4 kpa
Temperature T1 = 0 => T1 =. 0 + 273 =273
Temperature T2 =?
We have pressure temperature equation P1T1 = P2T2
=> T2 = P1T1 / P2 = (30.7 x 273) / 61.4 = 136.5
So the temperature for doubling the pressure is 136.5.
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
