Answer:
• 1 kilocaloric equals 1000 gram calories
• 1 kilocalorie is equals to 4184 Joules of energy.
Explanation:
One kilocalorie is equals to 1000 gram calories because one kilo is equals to or have 1000 grams. One kilocalorie is equals to 4184 Joules of energy while on the other hand, one calorie is equals to 4.184 Joules of energy because one calorie is 1000 times smaller than Kilocalorie so calorie has also 1000 times lower energy than kilocalorie. Kilo is the prefix which means 1000 so we can say that One kilocalorie is equals to 1000 gram calories.
The chemical energy is converted to mechanical energy to make the body move
The answer would be C. In fact, letter A already defines the Law of Definite Proportions. On the other hand, J.J. Thomson was responsible for the discovery of electrons through cathode ray tube experiments. The rest of the choices are true.
Answer:
![[OH^-]=1.7x10^{-6}M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D1.7x10%5E%7B-6%7DM)
Explanation:
Hello!
In this case, since the pOH of a solution can be computed when knowing the pH as shown below:
And therefore, the concentration of hydroxide ions based on the definition of pH:
![[OH^-]=10^{-pOH}](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D10%5E%7B-pOH%7D)
In such a way, we obtain:
![[OH^-]=10^{-5.78}=1.7x10^{-6}M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D10%5E%7B-5.78%7D%3D1.7x10%5E%7B-6%7DM)
Best regards
sorry, but im just learning some chemistry myself so i only know that the 1st blank is: Ph
hope you can find what the other 2 blanks are
