Answer:
Her error was that she did not subtract 12 from 8 correctly
Explanation:
Jackie did 8-12 instead of 12-8
Answer:
C. g/cm³
Explanation:
The slope is measured by calculating the variation of the Y values over the X values between two points on a line.
So, the formula is: Slope = Δy/Δx
That means that we also take the units.
In this case, the Y-axis unit is in g, while the X-axis unit is in cm³.
Dividing a Y-variation over an X-variation will give you g/cm³.
In this case, let's assume the line passes through (10,100) (not exactly, but close enough for the example), and it passes through (0,0)
So the slope would be: (100-0) g / (10-0) cm³ = 10 g/cm³
Answer:
A
Explanation:
The greatest concentration of atomic mass is in the nucleus because it is made up of protons and neutrons. The electrons surrounding the nucleus don't have as much mass as protons or neutrons.
Hopefully this helps...
<span>Un solid covalent de rețea constă din atomi reținuți împreună de o rețea de legături covalente (perechi de electroni împărțite între atomi de electronegativitate similară) și, prin urmare, pot fi considerați o singură moleculă mare. </span>
Answer:
47391.8 J
Explanation:
Q = m c Δt
For melting, Δt = (962-22)°C
Heat required to attain melting point = 145 x 10 ⁻³ x 236 x 940 =
= 32166.8 J
Heat required to melt at melting point = m L , L is latent heat of fusion.
= 145 x 10⁻³ x 105 x 10³ = 15225 J
Total energy required = 47391.8 J
