I think it’s D but don’t come at me if it’s wrong
Answer:
Explanation:
Na2CO3+Ca(NO3)2=CaCO3+2NaNO3
nNa2CO3=0.02
nCa(NO3)2=0.02
mCaCO3=0.02*100=2 gram
nNaNo3=0.04
Cm=2/15
V (speed) = f (frequency) * y (meant to be lambda) (wavelength)
y = v/f (v is speed of light --3.0*10^8m/s)
y = 3.0*10^8/1.5*10^13
The answer is y = 2.0*10-5.
Answer:
Nuclear fission power plants have the disadvantage of generating unstable nuclei; some of these are radioactive for millions of years. Fusion on the other hand does not create any long-lived radioactive nuclear waste. A fusion reactor produces helium, which is an inert gas.
Answer:
Temperature
Explanation:
It's called temperature.
This is because, in any substance an increase in temperature means that the particles on the average will move with greater speeds, or that they have greater kinetic energy while a decrease in temperature means that the particles on the average will move with lesser speeds, or that they have lesser kinetic energy.
