How is a mixture different from a chemical reaction?

Chemistry
1 answer:
GrogVix [38]3 years ago
5 0

Answer:

A mixture is made when two or more substances are combined, but they are not combined chemically. A chemical reaction is a transformation from one set of chemicals into another set.

Explanation:

A mixture can be homogeneous or heterogeneous, when homo, you cannot see each variable but hey are there. Hetero, means you can see each variable in the mixture. It is considered a mixture and not a chemical reaction because it can be reversed. It will always be able to go back to its separate forms and keep its original composition. When there is a chemical reaction, it is hard to separate and go back to the original variables because there is a molecular bond.

1. What is the molarity of a solution which contains 0.256 mol of a substance dissolved in 143 mL of solution.
LenaWriter [7]

Answer:

The equation for molarity is moles/liter for the first question you would do 0.256/0.143 liters to get 1.790 mol/L

Explanation:

The second problem you would do need to find the moles of NaCl which you would do by doing 4.89 g/58.44g/mol= 0.08367 then do 0.08367/0.600= 0.139 mol/L

The third problem would be the same steps as the second one.

The fourth problem would be (0.460M)(5.50L)= 2.53 moles

The following molecular equation represents the reaction that occurs when aqueous solutions of silver(I) nitrate and barium chlo
mrs_skeptik [129]

Answer:

Hey, I hope this helps. You gave the equation already balanced so there was no need to do so, the next thing we need to do after balancing is to split the strong electrolytes into ions. Once that is completed we cross off any reoccurring ions. That leaves us with our complete net ionic.

I also recommend you check out Wayne Breslyn on Yt. He is so helpful with equations like these.

How many grams are in 0.5 moles C6H12O6?<br><br><br><br> Show work please!
Nitella [24]
Molar mass of C6H12O6 = 6x12 + 12x1 + 6x16 = 180g

SO mass of 1 mole of C6H12O6 = 180g

mass of 0.5 mole of C6H12O6 = 0.5 x180g = 90g
