Hey!
According to scientists across the globe, Pluto is not a "planet", but a "dwarf planet." This also is determined when you were born and taught different ideals, cause everyone changed their sort of learning on planets overtime in our generation. Hope this helped!
Answer:
the approximate volume of 280 g of chlorine gas (Cl2) at STP is 78L Cl2
Answer is 67.8%
To find the percent yield the equation is actual yield over theoretical yield, and multiply by 100. In this problem it is 4.06996 / 6 = 0.678 x 100 = 67.8%
The subatomic particles located within the nucleus of the atom are Protons, Neutrons, and Electrons.
protons are positively charged
neutrons are neutrally charge
electrons are negatively charged
hope this helps
Answer:
The identity of the gas is Cl₂ (chlorine)
Explanation:
STP conditions are:
1 atm → Pressure
273.15 K → T°
So, we must use the Ideal Gas Law to get the moles.
Before that, we will think density as data where 3.164 g of diatomic gas are contained in 1 L of volume.
P.V = n . R . T
1 atm . 1 L = n. 0.082 L.atm/mol.K . 273.15K
1 L.atm / (0.082 L.atm/mol.K . 273.15K) = n
0.0446 mol = n
This quantity of diatomic gas, are 3.164 g so the molar mass will be:
Mass / mol = molar mass
3.164 g / 0.0446 mol = 70.9 g/m
The element (a diatomic molecule), which has that molar mass in the periodic table is the Cl₂.
1 Cl = 35.45 g/m
Cl₂. = 70.9 g/m
