False. Inertia will not slow it down, but air resistance or another force may. Assuming no other forces slow it down, inertia will not slow it - meaning it travels on forever.
Hope I helped! Thank you for posting your question, and feel free to ask if you have any more! :)
253.15
The temperature T in degrees Celsius (°C) is equal to the temperature T in Kelvin (K) minus 273.15:
T(°C) = T(K) - 273.15
Im pretty sure the answer is 6
Answer:
cm^3 —> dm^3
divide by 1000
159.5 — Mr of CuSO4
n (moles in mol) = c (concentration in mol/dm^3) * v (volume in dm^3)
0.100 mol of CuSO4 dissolved in 0.5dm^3 of water
calculate for mass of CuSO4 dissolved in 0.03dm^3 (30cm^3) of the solution
n = m/Mr
m = n*Mr
if 0.1 mol is dissolved in 0.5 dm^3 of water
0.5/0.03 ≈ 16.66666667
0.1 = 0.05
0.1 / 16.66666667 = 0.006
0.5 / 16.66666667 = 0.03
0.006 (mol of CuSO4) = 0.03 (dm^3 solution)
0.006 * 159.5 = 0.957 g
I think this is the answer
B)The number of protons.
c) their atomic masses are different.
