Answer:
CO2; H2SO4; NaCl
Explanation:
Compounds are substances containing different elements!
since F2 and N2 only has the element flourine ; nitrogen
The initial concentration of solution is 0.0693 M. The volume of solution taken is 10 mL and it is diluted to a final volume of 500 mL.
According to dilution law, the product of initial concentration and volume is equal to the product of final concentration and volume as follows:

Here,
is initial concentration,
is final concentration,
is initial volume and
is final volume.
Rearranging to calculate final concentration,

Putting the values,

Therefore, concentration of the resulting solution is 0.001386 M.
There are no options but law of conservation of energy states that energy can’t be created or destroyed.
answer is B
because both sides have equal numbers of atomos
