Answer:
168.0 g
Explanation:
First thing, write a balanced chemical equation:
n(H2SO4) = concentration * volume
= 1.0 M * 2.0 L
= 2.0 mol
According to the balanced equation, 1 mol of acid requires 2 mol of sodium bicarbonate. This means that 2 mol of acid requires 2 mol of sodium bicarbonate. What mass of sodium bicarbonate is this?
mass (NaHCO3) = number of moles * molar mass
= 2.0 mol * 84.0065 g/mol
= 168.0 g
Answer: It will lead to form a white colored product .
Explanation: The reaction of iodine and zinc involves the direct reaction between a metal and a non-metal leading to the synthesis of a metal salt.
During this reaction, heat is released (exothermic reaction) while forming Zinc Iodide() which can be easily obtained by evaporating the solvent.
By looking at the stoichiometric coefficients of reactants and products, we observe that whole of the iodine has reacted with zinc.
Answer:
Explanation:
Density can be found by dividing the mass by the volume.
The mass of the water is 50.0 grams.
The volume of the water is 50.0 milliliters.
Substitute the values into the formula.
Divide.
The density of the water is 1.0 grams per milliliter. Also, remember that the density of pure water is always 1.0 g/mL or g/cm³
I think this website would help u! good luck though
plus why are there too many commas
