Sorry, I’m not good with this stuff, but I think it’s Ti
Q = mCΔT
Q is heat in joules, m is mass, C is specific heat, and delta T is change in temp
2099 J = (40.27g)(C)(148.5 - 24.8) = .421 J / gram K
There are 118 elements in the periodic table.
An object on the moon is 1/6 of the weight of an object on Earth
To find the answer to your question, divide the number of N on Earth by 6, 6N / 6 = 1N
Hope this helps!
Answer:
The correct answer is option e.
Explanation:
The formula used for root mean square speed is:
where,
= root mean square speed
k = Boltzmann’s constant =
T = temperature
M = Molar mass
= Avogadro’s number =
Root mean square speed of carbon dioxide molecule:
Temperature of the mixture = T =?
Molar mass of carbon dioxide = 44 g/mol = 0.044 kg/mol
T = 533.87 K
Root mean square speed of nitrogen molecule:
Molar mass of nitrogen = 28 g/mol = 0.028 kg/mol
689 m/s is the root-mean-square speed of the nitrogen molecules in the sample.
