Answer:
A bar graph
Explanation:
a bar graph keeps track of things like the length of something. of course there will be other things that it can keep track of but for your case, you will want to use a bar graph.
I hope that this helps! Best of luck!
Answer:
2NaOH(aq) + H2SO4(l) → 2H2O(l) + Na2SO4(aq)
Explanation:
2NaOH(aq) + H2SO4(l) → 2H2O(l) + Na2SO4(aq)
Answer:
The answer is option D.
Explanation:
In balancing in acidic solutions, the oxygen is accounted for by adding a water molecule or H2O on the side that needs oxygen and 2H+ molecules for every H20 molecules placed on the other side of the equation.
The H+ and H2O molecules are in the ratio 2 : 1

Answer:
Mass of Fe produced = 4.468 g
Explanation:
Given data:
Mass of Fe produced = ?
Mass of Fe₂O₃ react = 6.50 g
Solution:
Chemical equation:
2Fe₂O₃ → 4Fe + 3O₂
Number of moles of Fe₂O₃ ;
Number of moles = mass/molar mass
Number of moles = 6.50 g/159.69 g/mol
Number of moles = 0.04 mol
Now we will compare the moles of iron and ironoxide.
Fe₂O₃ : Fe
2 : 4
0.04 : 4/2×0.04 = 0.08 mol
Mass of iron produced:
Mass = number of moles × molar mass
Mass = 0.08 mol × 55.85 g/mol
Mass = 4.468 g
