Answer: The final temperature of the water will be 
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed=
Joules
m= mass of water = 
c = specific heat capacity = 
Initial temperature of the water = 
= 
Final temperature of the water = 
= ?
Putting in the values, we get:
The final temperature of the water will be
Answer:
The total number of electrons in a valence shell is called valence electrons. The electron configuration of rubidium shows that the last shell of rubidium has an electron. Therefore, the valence electrons of rubidium(Rb) are one.
It has 19 electrons. I hope this helps.
Answer:
Explanation:
Hello.
In this case, since the definition of by-mass percent is:
Whereas we know the percent as 11.9 % and the mass of the solution as 225g, so we compute the grams of solute as follows:
Best regards.
