Answer:

Explanation:

Because unlike ionic bonds (metal and a non-metal) where electrons are "stolen", covalent bonds are defined by the sharing of electrons between non-metals.

(a) if a sample containing 2.00 ml of nitroglycerin is detonated, how many total moles of gas are produced? (b) if each mole of

gregori [183]

Detonation of nitroglycerin:

$4C_3H_5N_3O_9 ------\ \textgreater \ 12CO_2+6N_2+O_2+H_2O$

Mass nitroglycerin = 2.00 mL x 1.592 g/mL = 3.184 g

Moles = mass / molar mass = 3.184 g/ 227.0872 g/mol = 0.01402

the ratio between nitroglycerin and Carbon dioxide is 4 : 12
So, moles CO2 = 0.01402 x 12 / 4 =0.0420

the ratio between nitroglycerin and N2 is 4 : 6
moles N2 = 0.01402 x 6 / 4 =0.0841

the ratio between nitroglycerin and O2 is 4 : 1 
moles O2 = 0.01402 x 1 / 4 = 0.0035

the ratio between nitroglycerin and water is 4 : 1 
in the same way moles water = 0.005258 

total moles = 0.0420 + 0.0841 + 0.0035 + 0.005258 = 0.130758

0.130758 x 55 = 5.78 L 

Mass N2 = 0.0841 mol x 28.0134 g/mol = 2.3548 g

What is the difference between a physical and chemical change? (Use words reactants, products, atoms and molecules.)

jeka94

Answer:

A physical change, such as a state change or dissolving, does not create a new substance, but a chemical change does. In a chemical reaction, the atoms and molecules that interact with each other are called reactants. In a chemical reaction, the atoms and molecules produced by the reaction are called products.

Answer:

Q.1

Given-

Volume of solution-1 L

Molarity of solution -6M

to find gms of AgNO3-?

Molarity = number of moles of solute/volume of solution in litre

number of moles of solute = 6×1= 6moles

one moles of AgNO3 weighs 169.87 g

so mass of 6 moles of AgNO3 = 169.87×6=1019.22

so you need 1019.22 g of AgNO3 to make 1.0 L of a 6.0 M solution
