Give an example for each of the following terms: (a) matter, (b) substance, (c) mixture.

Explanation:

Matter is defined as any substance that has some mass and occupies volume.

Anything that we can observe is also matter.

For example, a solid wooden box of mass 15 kg is a matter.

When elements of pure substance that we cannot separate by physical methods until we break its chemical chain is known as a substance.

A substance can be present in solid, liquid, gaseous or plasma state.

For example, diamond, gold, water, salt etc are all pure substances.

A mixture is defined as the substance in which two or more substances are physically mixed together.

A mixture can be homogeneous if it contains uniform composition of solute particles into the solvent.

For example, salt dissolved in water is a homogeneous mixture.

A mixture that contains non-uniform composition of solute particles into the solvent is known as a heterogeneous mixture.

For example, sand in water is a heterogeneous mixture.

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.  

explanation:

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
