Answer:
Explanation:
The given equation is:
Based on the reaction stoichiometry:
2 moles of barium chloride (BaCl2) reacts with 2 moles of sulfuric acid (H2SO4) to form 2 moles of barium sulfate (BaSO4) and 4 moles of HCl
Although the reaction is balanced, the correct convention is to depict reactions in terms of the lowest molar ratio. Therefore the coefficients (2,2,4 and 4) can be divided by 2 to give:
It would be an physical change ; if you melt butter the butter goes from a solid to a liquid so therefore the physical state is changed.
Option 1/A (It is the first one)
Both have a continuous light spectra the fluorescent source makes a spectra with more intense bands of mercury

Answer:
0.499atm
Explanation:
The formula is
P1/V1 = P2/V2
so:
1.26atm/7.40L = P2/2.93L
then:
(1.26atm/7.40L)*2.93L = P2
= 0.4988918911atm
the answer must have 3 sig figs
