32.7 g Zn
Explanation:
First convert the amount of gas into moles:
11.2 L H2 × (1 mol H2/22.4 L H2) = 0.500 mol H2
Then use the molar ratio to find the amount of zinc necessary to produce the amount of gas above:
0.500 mol H2 × (1 mol Zn/1 mol H2)
= 0.500 mol Zn
Now use the molar mass of zinc to find the number of grams of zinc for the reaction to occur:
0.500 mol Zn × (65.38 g Zn/1 mol Zn)
= 32.7 g Zn
Answer:
Explanation:
1. First write the formula of each compound:
Sucrose : 
Water : 
Ethyl alcohol : 
Carbon dioxide : 
2. Write the equation with the reactants on the left and the products on the right:
3. Put the states of matter of each compound in the reaction, as the problem says:
aq = aqueous solution
g = gas
4. Balance each element.
The number of each atom must be the same on the left and on the right.
Answer:
Electrostatic Van de Waals forces act between molecules to form weak bonds. The types of Van der Waals forces, strongest to weakest, are dipole-dipole forces, dipole-induced dipole forces and the London dispersion forces. The hydrogen bond is based on a type of dipole-dipole force that is especially powerful. These forces help determine the physical characteristics of materials.
