(01.06 LC) Which statement is true about the substances present in a mixture?

They always consist of the same element.
They are always in the same state of matter.
They can be separated by physical methods.
They can only be separated by chemical methods.

They can be separated by physical methods

Explanation:

A mixture contains 2 or more substances which are occurring together. Although they are occurring together, it is important to note that they are not chemically bonded.

What we are trying to say is that there is no chemical bond between the substances present in a union.

They are particularly bonded physically. Hence, to separate a mixture into its constituent parts, we surely need to employ the use of a physical method that works to separate these substances into their different parts.

The physical method selected is based on the properties of the materials present in the mix

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.
