Answer:
i don't know what happened but r.i.p account
Answer:
One mole of any gas has a volume of 24 dm3 or 24,000 cm3 at rtp (room temperature and pressure).
Explanation:
Answer : The limiting reactant is
Explanation : Given,
Mass of = 30.0 g
Mass of = 75.0 g
Molar mass of = 44 g/mole
Molar mass of = 32 g/mole
First we have to calculate the moles of and .
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 5 mole of react with 1 mole of
So, 2.34 moles of react with moles of
From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.
Therefore, the limiting reactant is
Sodium - Na is a neutral atom with 11 protons and 11 electrons.
protons are positively charged and electrons are negatively charged. Since the number of protons and electrons are equal, there are equal amounts of both positive and negative charges therefore they cancel out giving Na an overall neutral charge.
Na has 1 electron in the outermost energy shell, to become stable and to gain a noble gas configuration it loses the electron in its outermost shell.
Once it loses its electron, there are 11 protons and 10 electrons, having an overall positive charge of +1. Once atoms lose or gain electrons they become ions, since Na loses electrons its called a cation.
So in Na⁺, +1 stands for the net charge of the ion which is +1 or in other words Na has just lost one electron therefore is +1 positively charged
Hydrogen can be used as a byproduct in the electrolysis of fuel
