Answer: 3571 L
Explanation:
According to the ideal gas equation:'
P = Pressure of the gas = 12000 Pa = 0.12 atm
V= Volume of the gas = volume of tank = ?
T= Temperature of the gas = 34°C = 307 K
R= Gas constant = 0.0821 atmL/K mol
n= moles of gas= 17
Therefore Volume of tank is 3571 Liters.
The volume that will be at 2.75 atm with constant temperature and molar amount is calculated using bolyes law formula that is P1V1=P2V2
P1=1.05 atm
V1=3.78 L
P2=2.75 atm
v2=?
by making V2 the subject of the formula V2= P1V1/P2
= 3.78 L x 1.05 atm/ 2.75 atm =1.44 L
The law of conservation of mass states that in a closed system, the mass of the system cannot change over time. Look at our example of the candle in the closed room. ... If you massed the reactants oxygen and wax, it would equal the mass of the products water and carbon dioxide.
The answer is chemical change
That is exploding of potassium metal when placed in water is chemical change.
When potassium is dropped into a beaker full of water then potassium moves about rapidly and then ignites within seconds, that is the metal is gone and all activity ceases.
So it an example of chemical change.
The reaction of potassium with water is as follows:
2K + 2H₂O ---->2KOH + H₂
Condensed electron configuration of :
Ga = [Ar] 3d¹⁰ 4s² 4p¹.
O = 1s² 2s² 2p⁴
Gallium belongs to group 13 of the periodic table with 3 valence electrons. Oxygen (Atomic number = 8 and electronic configuration = 2,6) belongs to group 16 of the periodic table with 6 valence electrons. To achieve the octet stability criteria 2 gallium atoms will donate their 3 electrons each to 3 oxygen atoms.
The 3 oxygen atoms due to their high electron attracting ability will accept those electrons resulting in Ga3+ cation and O₂⁻ anion.
Thus, the formula of their compound if Ga₂O₃.
