Answer:
24 g of C are needed to produce 1mol of CH₄
Explanation:
The reaction is:
2C (s) + 2H2O (l) → CH4(g) + CO2 (g)
2 moles of carbon react with 2 moles of water in order to produce 1 mol of methane and 1 mol of carbon dioxide.
If we want to produce 1 mol of methane, we need 2 moles of C
Let's find out the mass → 2 mol . 12 g/1 mol = 24g
Answer:
In order to determine which ball has a higher kinetic energy, we first look at the formula of kinetic energy which is:
kinetic energy = 1/2 * mass * velocity²
The factors influencing the kinetic energy of an object are its mass and its velocity. Both of the balls have the same velocity; however, the red ball has a greater mass. Therefore,
The red ball has greater kinetic energy, because it has a greater mass.
We may also determine these quantitatively using the formula given and the kinetic energy of the yellow ball works out to be 9 J and that of the red ball is 13.5 J.

Answer:
a message sent by telegraph and then delivered in written or printed form, used in the UK only for international messages since 1981
The answer should be compound
Gas particles want to be as free as they can, occupying as much space as they can because they are independent and the greater the temperature the greater their speed, when the temperature is low so is their speed, so they can attach to solvent molecules. When the temperature rises the gas molecules become more agitated and the glue can no longer take them inside the solvent.
Hope this helps!
