Answer:
The answer is A
Explanation:
Image A has the same species while image B has more species than A.
Answer:
I believe it is "Arsenenate"
Answer:
NaCl + Ag(NO₃) --> Na(NO₃) + AgCl
Explanation:
Chemical equation:
NaCl + Ag(NO₃) --> Na(NO₃) + AgCl
The given reaction represent the double displacement reaction. Anion and cation of both reactant exchange with each others.
The anion of sodium chloride(Cl⁻) combine with cation of silver nitrate Ag⁺ and NO₃⁻ combine with Na⁺.
The third equation is correct while others are in correct.
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
SORRY CAUSE IDK IF THAT HELPED :(
According to Balance chemical equation,
N₂ + 3 H₂ → 2 NH₃
1 mole of Nitrogen reacts with 3 moles of Hydrogen to produce 2 mole of Ammonia.
It is known that i mole of any gas at standard temperature and pressure occupies 22.4 L of Volume. So, we can also say,
22.4 L (1 × 22.4) of Nitrogen gas (in question it is taken in excess) reacts with 67.2 L (22.4 × 3) of Hydrogen gas to produce 44.8 L (22.4 × 2) of Ammonia.
Result:
44.8 L is the correct answer.
