Answer:
Self value and rational thinking.
Explanation:
If you don't want to fall in love with someone, list reasons as to why. Understand you're amazing and that you don't <em>need</em> to be with anyone. Self value is very important so you don't fall for people that you believe will support you better than you can.
Good luck! :]
Basically, they just allow us to see farther into space, therefore letting us see in closer detail what objects in space are made of, such as flaming balls of gas (stars).
Answer:
3) The calculated density would be high, because the volume would be incorrectly measured low.
Explanation:
Density is defined as mass per unit volume. It means the density is inversely proportional to the volume.
A solid with a hollow center will have high volume due to air inside the hollow area that will lead to low density.
But the error in the calculation of density is that the "density would be high, because the volume would be incorrectly measured low."
Hence, the correct answer is "3)"
Internal energy is a measure of the thermal energy of a substance. Internal energy is the portion of thermal energy that can be transferred. Thermal energy is the portion of internal energy that can be transferred.
Answer:
0.040M RbOH
Explanation:
The reaction of Rb with water is:
2Rb + 2H₂O → 2RbOH + H₂
As 2 moles of rubidium produce 2 moles of rubidium hydroxide, we need to find the moles of rubidium added. With these moles and the volume we can find molar concentration of RbOH as follows:
<em>Moles Rb = Moles RbOH -Molar mass Rb = 85.4678g)</em>
8.5g * (1mol / 85.4678g) = 0.099 moles RbOH
As 1dm³ = 1L, the volume in liters is 2.5L
That means molarity is:
0.099 moles RbOH / 2.5L =
<h3>0.040M RbOH</h3>
