Answer:
2AgNO3 + Cu = Cu(NO3)2 + 2Ag
Explanation:
First you see which side has the most elements. Which is Cu(NO3)2 + Ag. But, both sides have the same elements? But, on the reactants side, there is 2 of NO3. On the products side there is only one.
Reactants: Products:
Cu = 1 Cu = 1
NO3 = 1 NO3 = 2
Ag = 1 Ag = 1
They are all equal, except for NO3. So on the reactants side, you add a two to make it even.
2AgNO3 + Cu = Cu(NO3)2 + Ag
Reactants: Products:
Cu = 1 Cu = 1
NO3 = 2 NO3 = 2
Ag = 2 Ag = 1
Now, the NO3 is equal, But the Ag isn't. But, you can add a 2 on the <u>products</u> side so the whole equation becomes equal.
2AgNO3 + Cu = Cu(NO3)2 + 2Ag
Reactants: Products:
Cu = 1 Cu = 1
NO3 = 2 NO3 = 2
Ag = 2 Ag = 2
Answer:
acidic
Explanation:
The number of H+ and OH- ions are how pH is calculated
since pH is -log [H+] more H+ ions create a more acidic solution
((mass solute)/(mass solution)) * 100% =35%
mass CaCl2=0.35*352.5=123.4 g CaCl2
No, because plastic cups can be dissolved by organic compounds. Moreover, they are easily melted so a highly exothermic reaction can not be studied using them.
