Answer:
p wave
Explanation:
The P wave is designated the primary preliminary wave because it is the first to arrive at a seismic station after an earthquake. It travels at a speed usually less than 6 kilometers per second in the Earth's crust and jumps to 13 kilometers per second through the core.
It’s 100° celsius as an intensive property i think but you might wanna search up the difference between intensive and extensive :)
Answer:
Explanation:
Hello,
In this case, since the velocity is computed via the distance divided by the elapsed time:
We can easily compute the how far it will travel as shown below:
Best regards.
Answer:
The formula of the compound is Cu₂O.
Explanation:
From the question given above, the following data were obtained:
Mass of compound = 12.5 g
Mass of copper (Cu) = 11.1 g
Mass of oxygen (O) = 1.4 g
Formula of compound =?
The formula of the compound can be obtained as follow:
Cu = 11.1 g
O = 1.4 g
Divide by their molar mass
Cu = 11.1 / 63.5 = 0.175
O = 1.4 / 16 = 0.0875
Divide by the smallest
Cu = 0.175 / 0.0875 = 2
O = 0.0875 / 0.0875 = 1
Therefore, the formula of the compound is Cu₂O.
38 g / (3 x 10^23 molecules) * 6,02x10^23 molecules/mol = 76,25 g/mol.
