Answer:
One gram helium gas is equal to the 4.002602 g/mole
Explanation:
Helium gas is a gas or chemical element. The symbol of helium gas is He and the atomic number of this gas is 2. This gas is colorless, odorless, and tasteless. It is a non-toxic gas. It is found in the periodic table in the first place.
Helium is a very lightest gas and very abundant in nature in the universe. It is present in the universe around 24 percent. Helium is also called by another name that titan of sun. This is detected by the yellow line. The liquid form of helium gas is called cryogenics. This helium gas is used in lifting balloons and airplanes.
This is actually incorrect, the distance as stated above either from trough to trough or from crest to crest within a corresponding wave, would be referred or called as the wavelength of the given wave.
Answer:
When two liquids combine to form a new liquid, we call the liquids “miscible.” When two liquids do not mix together and instead form layers, we call them “immiscible.” The chemical properties of the liquids will determine if they will mix or not.
Explanation:
Answer:
PbSO₃(s)⟶PbO(s)+SO₂(g)
Explanation:
In order for an equation to be balanced, both <em>the charges</em> and <em>the masses </em>need to be the same in both sides of the equation.
In the case of the reaction PbSO₃(s)⟶PbO(s) +SO₂(g), there are no charges in either side, so it is already electronically balanced.
Regarding masses, let's see each element one by one:
Pb ⇒ There's 1 Pb in both sides already.
S ⇒ There's 1 S in both sides already.
O ⇒ There're 3 O in both sides already.
So the equation is balanced as is.
Moles = Mass/Molar Mass
By this formula 458/207+32 you should get your answer.
Answer is 1.916 mol to 4 sig. Fig.
