Answer:

Fe + CuO ----> FeO+ Cu

Explanation:

A word equation is a chemical equation in which the reactants and products are represented by words rather than the respective symbols of the species involved in the reaction.

Generally, when writing a balanced reaction equation, it is normal to ensure that the number of atoms of each element on the reactant side is the same as the number of atoms of the same element on the product side. This has been ensured in the reaction above.

The reaction above is possible because iron is higher than copper in the electrochemical series hence iron can displace copper from its compounds.

How many milliliters of a 1.25 molar hydrochloric acid (HCl) solution would be needed to react completely with 60.0 grams of cal

stich3 [128]

Answer:

2400 mL

Explanation:

$Ca + 2HCl \implies CaCl_2 + H_2$

According to this equation, the stoichiometric ratio between $Ca$ and $HCl$ for the complete reaction is 1:2.

We know that the number of moles of $Ca$ can be calculated using the mole formula. (number of moles = mass / molar mass)

Moles of Calcium = $\frac{60}{40}$ = 1.5 mol

So the moles of $HCl$ = $1.5 \times 2$ = 3.0 mol

Volume of HCl solution = Moles of HCl/ concentration of HCl

Volume of HCl solution = $\frac{3}{1.25}$ = 2400 mL

the equation demonstrates a reaction of sodium chloride and fluorine. 2NaCl+F2=2NaF+Cl2. in order for the reaction to proceed, f

slamgirl [31]

Answer: You would need 1 mole of Fluorine

Explanation:The equation is already balanced so just looking at the coefficients in the equation we can see that Sodium Chloride (2NaCl) needs two moles for this equation and fluorine (F2) only needs one.
