Answer:
Kernels are placed in a pan on a stove
Explanation:
Heat transfer by conduction involves the actual movement between particles of the medium. For conduction to occur, the particles must be in contact with the heating medium or the body at a higher temperatures.
For the popcorn kernels to conduct heat using the conduction heat transfer process, the kernels are placed in contact with the heat source using the frying pan. The stove is the heat source.
When put a knife in contact with fire, it is heat transfer by conduction.
We can determine the empirical formula by first converting each of the grams to moles. remember to do this, first, we need the molar mass of the molecules which can be calculated by adding the mass of the atoms from the periodic table.
molar mass of CO2= 44.0 g/mol
molar mass of H2O= 18.02 g/mol
now, lets determine the grams of each atom
Carbon: 23.98 g x (12.011 g / 44.01 g) = 6.54 g C
Hydrogen: 4.91 g x (2.0158 g / 18.02 g) = 0.55 g H
Oxygen: 10.0 - (6.54 + 0.55) = 2.91 g O
Now let's convert each mass to moles.
C: 6.54 g / 12.01 g / mol = 0.54 mol
H: 0.55 g / 1.01 g/mol = 0.54 mol
O: 2.91 g / 16.00 g/mol = 0.18 mol
now that we have the moles of each atom, we need to divide them by the smallest value to find the ration. If you do not get the whole number, you need to multiply until to get a whole number.
C: 0.54 mol / 0.18 mol = 3
H: 0.54 mol / 0.18 mol = 3
O: 0.18 mol / 0.18 mol = 1
empirical formula--> C₃H₃O
Both containers have the same number of molecules= 5.62 x 10²³
<h3>Further explanation</h3>
Given
22.4 L of hydrogen gas
22.4 L of oxygen gas
25°C and 1 atm.
Required
true statement
Solution
Conditions at T 25 ° C and P 1 atm are stated by RTP (Room Temperature and Pressure). Vm in this condition = 24 liters / mol
and from Avogadro's Law :
<em>At the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles </em>
So two gas have the same molecules
1 mol = 6.02 x 10²³ molecules
24 L = 1 mol, so for 22.4 L :
Answer:
False
Explanation:
The relationship between energy and amplitude can be written as eαa^2
This means that the energy of a wave is directly proportional to the square of the amplitude.
