Answer;
FeSO4 (aq) + H2 (g)
Explanation;
The reaction between iron and dilute sulfuric acid gives a salt and hydrogen gas. (iron (ii) sulfate and hydrogen gas).
The equation for the reaction is;
Fe(s) + H2SO4 (aq) = FeSO4(aq) +H2(g)
Answer: 175.35g
Explanation: A 3 M solution has 3 moles of solute per litre.
The mass of one mole of NaCl equals the MW of NaCl MW = 35.45 + 23 =58.45 g/mol
The mass of 3 moles is 58.45 g/mol ×3 mol=175.35 g NaCl or 200 g rounded to one sigfig.

Answer:
It's mileage is 5.95 km per liter.
<u>Answer:</u> The binding energy for lithium-6 nuclei is 3.09 E+11
<u>Explanation:</u>
Binding energy is defined as the energy which holds the nucleus together. It is basically the product of mass defect and the square of the speed of light.
This energy is calculated by using Einstein's equation, which is:
where,
E = Binding energy of the atom
= Mass defect = 0.0343g/mol = 
(Conversion factor: 
)
c = speed of light = 
Putting values in above equation, we get:
(Conversion factor: 
)
Hence, the binding energy for lithium-6 nuclei is 3.09 E+11
