Pyrotechnic compositions emit light by three basic processes - incandescence (blackbody radiation) atomic emission, and molecular emission.
50g U ( 1mol/ 238.03g) = .2 moles
238.03 is the molar mass of uranium- can be found on periodic table
Answer:
0.144M
Explanation:
First, let us write a balanced equation for the reaction. This is illustrated below:
HNO3 + KOH —> KNO3 + H20
From the equation,
nA = 1
nB = 1
From the question given, we obtained the following:
Ma =?
Va = 30.00mL
Mb = 0.1000M
Vb = 43.13 mL
MaVa / MbVb = nA/nB
Ma x 30 / 0.1 x 43.13 = 1
Cross multiply to express in linear form
Ma x 30 = 0.1 x 43.13
Divide both side by 30
Ma = (0.1 x 43.13) /30 = 0.144M
The molarity of the nitric acid is 0.144M
Yes, because they are in the same group also because they are similar with the <span>chemical properties</span>
The correct answer is A
Filter out the sand, because the sand does not dissolve in water, and then evaporate water from sugar solution
