Answer:
Explanation:
Mᵣ: 58.44 278.11
Pb(NO₃)₂ + 2NaCl ⟶ PbCl₂ + 2NaNO₃
m/g: 26.3
1. Moles of NaCl
(b) Moles of PbCl₂
(c) Theoretical yield of PbCl₂
(d) Percent yield
The answer is A.
215K is equivalent to -58.15 °C and temperature corresponds with the average kinetic energy.
So the 15°C has a higher energy level than 215K.
Decreases as you move left to right
How do you find density?
Well, first D=m/v
D=density
M=mass
V=Volume
Volume of cube: 3*3*3=9cm cubed
Mass of cube: 25g
D=25g/9cm cubed
<span>2.8 g/cm cubed is the answer.

Keeping your arm straight in front of you, you rotate 90° to your left, and see the left side of the circle lit while the right side is dark. Half the ball is still lit up, but you can see only part of the lit area. As you continue to rotate, you see a different amount of the ball.
