Answer:
6.25 mL
Explanation:
1.25% of 500 mL is ...
0.0125×(500 mL) = 6.25 mL
Since 1.25% of the 500 mL of solution is bleach, that's how much you need. That amount is 6.25 mL.
Answer:
20703.6J
Explanation:
Quantity of heat (Q) = mass of dioxane × enthalpy of fusion
Mass of dioxane = 142g
Enthalpy of fusion of dioxane = 145.8J/g
Q = 142g × 145.8J/g = 20703.6J
The correct answer is - latitude.
The latitude in many ways is the most important factor in determining the climate of a place. The reason for that is mostly the shape of the planet, which doesn't allow the Sun light to be equally distributed on all of its surface. The lower the latitude, the more direct and more concentrated the Sun light, thus the place will be warmer. The higher the latitude, the sharper the angle of the fall of the Sun light, thus more dispersed Sun light, which will result in a much colder climate.
The balance chemical equation is :
2HCL + Na2CO3 -----> 2NaCl + H2O + CO2
According to Question,
Given,
Molarity of HCL = 1.75 m
Sodium Carbonate (Na2CO3) = 0.100 m
For finding out the molarity,
c = n solute / Vsolution => n = c.Vsolution
nCO^2-3 = 0.100 mol L^-1 . 0.750 L = 0.0750 moles of CO^2-3
0.0750 moles of CO^2-3 . 2 moles H3O^+ / 1 mole CO^2-3
= 0.150 moles of H3O^+
As we have already know the molarity of HCL , we easily calculate what volumes by many moles.
c = nsolute / Vsolution => Vsolution = nsolute / c
VH3O^+ = 0.150 moles / 1.75 mol L^-1 = 0.0857 L
