Answer:

1. 2+ (Cu^{2+}).

2. 0 (Cu^0).

Explanation:

Hello,

In this case, the described chemical reaction is a redox reaction in fact, since the oxidation states of both magnesium and copper change as shown due to the displacement:

Mg(s)+Cu(NO_3)_2(aq)\rightarrow Mg(NO_3)_2(aq)+Cu(s)

Therefore:

1. Since copper is the cation in the copper (II) nitrate, the (II) means that its charge is 2+ (Cu^{2+}).

2. Since copper is alone, it means no electrons are being neither shared not given, its charge is 0 (Cu^0).

Best regards.

When using 100ml or 50ml graduated cylinder to what decimal place can your volume be estimated?<br>​
Olegator [25]

Answer:

I know that the 100-mL graduated cylinders are always read to 1 decimal place.

I think for 50 mL graduated cylinders, it lets you measure volumes up to 50.0 mL to the nearest 0.1 or 0.2 mL, depending on your exact cylinder.

shtirl [24]

Answer:

1.what I observe.

Explanation:

The dependent variable in an experiment is what is being observed in the experimental procedure.

This variable is the one that is closely tied to the effects originating from changing the independent variables.

  • Independent variables are the ones that cause the observation being studied.
  • The effects produced and then studied are the dependent variables.
