_AgNO3 + _ Cu → _ Cu(NO3)2 + - Ag

Chemistry
1 answer:
GuDViN [60]3 years ago
6 0

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

What is the purpose of the stairstep pattern on the periodic table of the elements?
Mamont248 [21]

Answer: The bold staircase in the periodic table allows us to classify which elements are metalloids.

Explanation: Additionally, it acts like a "divider" that allows us to properly distinguish the metals from the non-metals in the periodic table.

A 20.00-mL sample of a weak base is titrated with 0.0568 M HCl. At the endpoint, it is found that 17.88 mL of titrant was used.
nata0808 [166]

Answer: 0.0508mL

Explanation: Using the basic formula that states: C acid * V acid = C base * V base. we have:0.568 * 17.88 = 20 * C base.

therefore concentration of the base is 1.0156/20 = 0.0508 mL
