If combined with oxygen. the reaction is usually combustion. in this case, it is the combustion of ethene
Answer:
The pH of a 0.10 Maqueous Ba(OH)2 solution at 25°C is 13.30
Explanation:
The balanced equation is Ba(OH)2(s)→Ba2++2OH−
This indicates that the concentration is 0.2 M
We will find H+ ion concentration
As we know that
[H+][OH−]=1.0×10−14M
Given -
[OH−]=2.0×10−1M
Putting value of [OH-] in above equation we get -
[H+]=5.0×10−14M
pH=−log10[H+]
pH=−log10[5.0×10−14] = 13.30.
Answer:
47C
Explanation:
Recall the equation for specific heat:
q = mcΔT
300 = 3 x 4.184 x (T - 23)
T = 47
Children should not be put into the situations such as the one depicted in this given item. They are still to young to weigh in as to which parent will they will be happier with. Also, they will be very much burdened with the idea of splitting parents disallowing them to focus on other things currently going on.
