Answer: The volume of the gas is 0.84 Liters
Explanation:
According to ideal gas equation:
P = pressure of gas = 1530 mm Hg = 2.01 atm (760mmHg=1atm)
V = Volume of gas = ?
n = number of moles = 0.275
R = gas constant =
T =temperature =
Thus the volume of the gas is 0.84 Liters
A homogenous mixture is uniform and thus hard to recognize as a mixture. An example is water.
N(C)=5,02·10²² atoms
calculation check:
N(C)=(1/12)*6.022*10²³=0.5018*10²³≈5.02·10²²
Answer: The number of neutrons will increase as we move from left to right in a periodic table.
Explanation:
Atomic number is equal to the number of protons.
Mass number is the sum of number of neutrons and number of protons.
As we move from left to right, both the atomic number and mass number increases.
For example: As we move from Lithium to berrylium to boron to carbon to nitrogen to oxygen to fluorine to neon , the number of neutrons increase from 4 to 5 to 6 to 6 to 7 to 8 to 10 to 10.
Thus the number of neutrons will also increase as we move from left to right in a periodic table.
The answer is baking a cake.
