Explanation:
We will balance equation which describes the reaction between sulfuric acid and sodium bicarbonate: as follows.
Next we will calculate how many moles of
are present in 85.00 mL of 1.500 M sulfuric acid.
As, Molarity = 
1.500 M = 
n = 0.1275 mol
Now set up and solve a stoichiometric conversion from moles of
to grams of
. As, the molar mass of
is 84.01 g/mol.
= 21.42 g
So unfortunately, 15.00 grams of sodium bicarbonate will "not" be sufficient to completely neutralize the acid. You would need an additional 6.42 grams to complete the task.
Answer:
A nuclear reaction releases more energy per gram and appears to violate the law of conservation of mass.
Explanation:
- In nuclear reactions there arises a shift in the nucleus of the atom. This results in the production of a different element altogether. While in chemical reactions the electrons are rearrangement and there is no change in the nucleus.
- Factors like temperature, pressure, and catalysts do not affect the rate of nuclear reactions while they influence the chemical reactions.
- The change in the energy is higher in nuclear reactions. It arises out of the destruction of mass.
Answer:
72.04g Ti and 7.75g Na
Explanation:
1.505 mol Ti x (47.87g/1 mol) = 72.04g Ti
0.337 mol Na x (22.99g/1 mol) = 7.75g Na
