5. 1.00 mol HNO3 is treated with 4.47 g of magnesium. Calculate the number of moles of
ruslelena [56]

Answer:

The balanced equation is:

2 HNO3 + Mg ---> Mg(NO3)2 + H2

From the equation, we can see that we need twice the moles of HNO3 than the moles of Mg

Moles of Mg:

Molar mass of Mg = 24 g/mol

Moles = Given mass / Molar Mass

Moles of Mg = 4.47 / 24 = 0.18 moles (approx)

Hence, 2(moles of Mg) = 0.36 moles of HNO3 will be consumed

Number of moles of HNO3 after the reaction is finished is the number of unreacted moles of HNO3

Unreacted moles of HNO3 = Total Moles - Moles consumed

Unreacted moles of HNO3 = 0.64 moles (approx)

Since we approximated the value of moles of Mg, the value of remaining moles of HNO3 will also be approximate

From the given options, we can see that 0.632 moles is the closest value to our answer

Therefore, 0.632 moles will remain after the reaction

How many moles of carbon dioxide are produced from 8.73 moles of tristearin?​
matrenka [14]

Answer:

Explanation:

  8.73 mol                                         x mol

2 C57H110O6(S) + 163 O2(g)  --->  114 CO2(g) + 110 H2O(I)

2 mol                                               114 mol

8.78 mol (114mol/2 mol) =500.46 mol

Which member of the alkali metals has the highest
natulia [17]

Answer:

E)Li

Explanation:

Electronegativity is the tendency of an atom to attract a pair of bonding electrons. In the periodic table, electronegativity increases across the period and decrease down the group.

This means the element at the top of the group would have the highest electronegativity.

The correct option is;

E)Li
