Answer:
first, to get rid of the division, multiply both sides by 2. you will get 7x=98. next, divide both sides by 7 to isolate x. x=14
Answer:
Cesium (Cs)
Explanation:
This eliment has an ionization energy of 3,8939
H2se is a ionic bond which requires higher energy to change into a gas, while h2s is a covalent bond requiring less energy
Nobel gas, it is in the last row of the periodic table and therefore is a noble gas
Answer:
0.00559 mol
Explanation:
The following data were obtained from the question:
V = 140mL = 0.14L
T = 296K
P = 98.2kPa = 98200Pa
Recall: 101325Pa = 1atm
98200Pa = 98200/101325 = 0.97atm
R = 0.082atm.L/Kmol
n =?
The number of mole (n) can be obtained as follows:
PV = nRT
n = PV /RT
n = (0.97x0.14)/(0.082x296)
n = 0.00559 mol
Therefore, the number of mole of the gas present is 0.00559 mol
