If you have 560 grams of magnesium. what mass of magnesium oxide will be produced?

=933.3 grams

Explanation:

Magnesium reacts with oxygen producing magnesium oxide according to the following equation.

2Mg₍s₎ + O₂₍g₎→ 2MgO₍s₎

From the above equation, 2 moles of Magnesium produces 2 moles of magnesium oxide. Therefore the ratio of magnesium to magnesium oxide produced is 1:1

1 mole of magnesium oxide has a mass of: 24+16 =40 grams

560 grams of magnesium=560/24 moles

=70/3 moles.

Since the ratio is 1:1 the reaction produces  70/3 moles of magnesium oxide.

70/3 moles of MgO= 70/3 moles× 40 grams

=933.3 grams

Here's what I get.

Explanation:

(d) Mass of chlorine

(i) We know we will need an equation with masses and molar masses, so let’s gather all the information in one place.  

M_r:                  70.91      58.44

            2Na   +   Cl₂ ⟶ 2NaCl

m/g:                                   117

(ii) Calculate the moles of NaCl

(iii) Calculate the moles of Cl₂

The molar ratio is (1 mol Cl₂ /2 mol NaCl)

(iv) Calculate the mass of Cl₂

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
