The answer is (2) 12mL. The reaction equation is NaOH + HCl = NaCl + H2O. So the mol number of NaOH is equal to HCl. The concentration of NaOH is twice of HCl so the volume of HCl is twice of NaOH.
Answer:
45.3 KPa
Explanation:
From the question given above, the following data were obtained:
Total pressure (Pₜ) = 101.3 KPa
Pressure of Hydrogen (Pₕ) = 56 KPa
Pressure of Oxygen (Pₒ) =?
The pressure of oxygen in the mixture can be obtained as follow:
Pₜ = Pₕ + Pₒ
101.3 = 56 + Pₒ
Collect like terms
101.3 – 56 = Pₒ
Pₒ = 45.3 KPa
Thus, the pressure of oxygen in the mixture is 45.3 KPa
Answer:
Oxygen difluoride
Explanation:
I looked it up
Could I have a brainliest pls I only need a few more :)
Explanation:
Write a balanced equation, ionic equation and the net ionic equation for the following:
A) Li2SO4 + Sr(NO3)3 --->
B) H2SO4 + Na2CO3 --->
You made a typo: that's Sr(NO3)2
Molecular:
Li2SO4(aq) + Sr(NO3)2(aq) ==> SrSO4(s) + 2LiNO3(aq)
ionic:
2Li^+(aq) + SO4^2-(aq) + Sr^2+(aq) + 2 NO3^-(aq) ==> SrSO4(s) + 2Li^+(aq) + 2NO3^-(aq)
NET ionic:
Just cancel the ions common to both sides to leave you with
Sr^2+(aq) + SO4^2-(aq) ==> SrSO4(s)
Answer: D the rate that varies more with temperature
Explanation: reaction with greater activation energy is not feasible ordinarily as the reacting molecules have little or no energy to overcome the activation energy. But as the temperature of the reaction is increased, the reacting molecules gains more energy to overcome the energy barriers(activation energy) hence proceeding to form products. In this case, the rate of the reaction depends on the temperature. So an increase in temperature will increase the kinetic energy of the molecules thereby increasing the rate of the reaction and a decrease in temperature will leads to a decrease in the rate of the reaction.
