Question

(a) For the double displacement reaction and find the mole ratio between the product and reactant for the constituents that contain the element: magnesium.

(b) Assume that you have 2.8 moles of the reactant that contains your element, how many moles of the product are created? (HINT: use the ratio above to find the moles of product)

Reactant:

Product:

(d) Assume you have 100 grams of the reactant, how many moles does that represent. (HINT: use average molar mass above to convert the grams to moles)

(a) How many moles of the product are created? (HINT: use the mole ratio above to convert the moles of reactant to moles of the product)

Moles of product:

(b) Convert the moles of the product to grams. (HINT: use the average molar mass of the product to convert the moles to grams)

Grams of product:

Assume that a certain amount of the second reactant produced 4 moles of product that contains your reactant. Which reactant created a smaller number of moles?

Which reactant is the limiting and excess reactant?

(this question is a set)

What are the coefficients of all reactants and products of the double
displacement reaction?
Reactants: Reactants in double displacement reaction are BaCl2 and
MgSO4 and their coefficients are 1 and 1.
Products:Products in double displacement reaction are BaSO4 and
MgCl2 and their coefficients are 1 and 1.

• Write 2 balanced chemical reactions, one single displacement or
decomposition or synthesis reaction, and one double displacement
reaction, that include your element.
Single displacement or decomposition or synthesis: MgCO3(s) →
MgO(s) + CO2(g)
Double displacement: BaCl2(aq) + MgSO4(aq) → BaSO4(aq) +
MgCl2(aq)

Expert Solution

Step 1

Double displacement reaction is a reaction in which exchange of ions occurs between the reactants to form two new compounds.
$m o l e r a t i o = \frac{n u m b e r o f m o l e s o f p r o d u c t}{n u m b e r o f m o l e s o f r e a c \tan t}$

$\begin{array}{rcl} M o l a r m a s s o f M g a t o m & = & 24.305 g / m o l \\ M o l a r m a s s o f C h l o r i n e a t o m & = & 35.45 g / m o l \\ M o l a r m a s s o f H y d r o g e n a t o m & = & 1 g / m o l \\ M o l a r m a s s o f O x y g e n a t o m & = & 16 g / m o l \end{array}$
