Answer:
It is A).
Explanation:
Silver (Ag) goes from the pure metal to Ag+ losing 1 electron so it is oxidised.
The hydrogen ion gains electrons and is reduced.
Answer:
In 0.7 liters (700 ml) there are 122, 85 grams of NaCl
Explanation:
We calculate the weight of 1 mol of NaCl:
Weight 1 mol NaCl= Weight Na + Weight Cl= 23+35,5 g= 58,5g/mol
1 mol NaCl-------58,5 g
3mol NaCl -------x= (3mol NaClx58,5 g)/1 mol= 175, 5 g
3M (175,5 g in this case)---> 3 moles in 1 L of solution
1 L-----175,5 g NaCl
0,7L--x= (0,7Lx175,5 g NaCl)/1L =122,85 g NaCl
True or for the flash it gave him his speed when it hit something and exploded and gave him the powers from the speed force but that is just nonfiction I would say that is true.
H₂ = 2 g/mol
1 x 2 = 2 g of H₂
________________________
K = 39.09 g/mol
2 x 39.09 = 78.18 g of K
________________________________
Mg = 24.3 g/mol
3 x 24.3 = 72.9 g of Mg
_________________________________
He = 4 g/mol
4 x 4 = 16 g of He
___________________________________
Order : K , Mg , He and H₂
hope this helps!
In chemistry, neutralization is a chemical reaction in which an acid and a base react quantitatively with each other, and where the final Ph of the solution is neutral (7).
In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.
