Step OneFind the moles of HCl
C = 1.0 mol/L
V = 75 mL = 75 / 1000 = 0.75 L
Note the concentration is in Liters.
<em>Formula</em>
n = C*V
<em>Solve</em>
n = 1.0 * 0.075
n = 0.075 moles
Step two Adjust the number of moles of HCl
How every mol of H2 produced, you will require 2 mol of HCl
2/1 = 0.075/x Cross multiply
2x = 0.075 Divide by 2
x = 0.075 / 2
x = 0.0375

<u><em>I HOPE IT WILL BE YOUR ANSWER:</em></u>
Explanation:
As given
60 min = 50 gm (1)
then we know half-life mean half amount decay time
so we can write as the half of 200 is 100 gm hence
T 1/2 = 100 (2)
solving these two equation by cross multiplication we will get
T 1/2 = 120 min

To sterilize the said baby bottle we have to raise the temperature from 22.0 degrees Celsius to 65 degrees Celsius and in order to determine the amount of heat that has to be supplied, we need the heat that would be absorbed by the baby bottle. First, we need to know the material of that baby bottle which, for this case, is made up of glass since we need the specific heat capacity of the material wherein for glass it is equal to 0<span>.84 J / g C. We determine the heat as follows:
Heat absorbed = Heat to be supplied = Heat transferred m C (T2 - T1)
Heat transferred = 50.0 g (0.84 J/ g C) (95 C - 22 C) = 3066 J</span>
Answer:
OF6
Explanation:
Oxygen and fluorine have almost the same electronegativity, so oxygen isn't able to donate enough electron density to fluorine to form OF6. Atomic size. There isn't enough room around an oxygen atom for six fluorine atoms.
