What is the solution to this equation?

Fantom [35]

Answer:

x=-17

Step-by-step explanation:

Original Equation;

x+12=-5

The 12 will cross the equal sign so it will become -12. So it's going to be;

x=-5-12

There are two negative number so you add them and when you add them it would still be negative. And you would have to add them because when there are two negative numbers without any other sign you will have to add so it's going to be;

x=-17

This is the final answer!!!

3(12-3y^2) Help solve this please

HACTEHA [7]

Step 1. Distribute

 $3*12+3*-3 y^{2}$

Step 2. Simplify $3*12$ to $36$

$36+3*-3 y^{2}$

Step 3. Simplify $3*-3 y^{2}$ to $-9 y^{2}$

$36-9 y^{2}$

Done! :)

1. what would the effect have been on the calculated formula weight ([9] above) of your unknown as compared to the true formula

kramer

If the solution is blue-green, this indicates that some copper is still present in the solution and that not all of it has precipitated. Expect it to be too low because you will have less mass.

With very few exceptions, all copper(I) (cuprous) compounds are diamagnetic and colorless. Cu2O, Cu2Cl2, and cuprous sulfide are a few of the significant commercial compounds of copper(I) (Cu2S).

The molar mass of the element copper is determined by looking at its average atomic mass, which is 63.55 AMU on the periodic table. Since it is also our molar mass, we will now put it in a different unit: grams over moles (63.55 gmol). That is copper's molar mass.

If the solution is blue-green, there is still copper in the solution and not all of it has precipitated. Because you will have less bulk, anticipate it to be too low.
