Answer:
Sn(s) + MgBr2(aq) --> SnBr2(aq) + Mg(s)
Explanation:
<em>Decide whether a chemical reaction happens in either of the following situations. </em>
- A reaction happens. The type of this reaction is the single replacement reaction.
<em>If a reaction does happen, write the chemical equation for it.</em>
Sn(s) + MgBr2(aq) --> SnBr2(aq) + Mg(s)
H2O became a vapor when heated because thats the only one that can go back to its normal state, which is what a physical change is.
Answer:
a substance made by mixing other substances together.
Explanation:
A mixture is a substance made by mixing two or more substances together.
The alcohol concentration of the mixed solution is 20%
Simplification :
Based on the given condition, formulate :
35% ×0.40 + 0.6 ×10% ÷{ 0.4+0.6}
Calculate the product :
Calculate the sum or difference :
Any fraction with denominator 1 is equal to numerator : 0.2
Multiply a number to both numerator, denominator : 0.2 ×
Calculate the product or quotient :
A fraction with denominator equals to 100 to a percentage 20%.
How do you find the concentration of a mixed solution?
In general when your are mixing two different concentrations together first calculate number of moles for each solution (n=CV ,V-in liter) then add them together it will be total moles,then concentration of mixture will be = total moles / total volume(liter).
