The correct answer is Kinetic energy
A non-metal element bonds with a metal element.
in the periodic table IA and IIA are metal elements so they usually react with nonmetal elements of group VIIA.
Answer:
There is actually 1 mole in 54.3 g of CO2
Find the number of moles of sodium you have:
<span>n = m/M where m is your 20g of sodium and M is 22.99 g/mol. </span>
<span>Look at the stoichiometry of the equation - it's 2:2 when you are producing NaOH. So if you took 1 mole of Na, it'd produce 1 mole of NaOH (as the ratio is equal). </span>
<span>That means that your moles of sodium is equal to the moles of NaOH produced. Use the molar mass of NaOH - which is 39.998 g/mol along with your calculated number of moles to get the mass (the formula rearranges to m = nM). </span>
<span>This figure is the theoretical yield - what you would get if every last mole of sodium was converted into NaOH. </span>
<span>What you get in practice is the experminetal yield, and the percentage yield is the experimental yield divided by the theoretical yield - and then multiplied by 100%.</span>
Rhizobium: are nitrogen-fixing bacteria that live in the nodules of legumes which convert nitrogen in soil into nitrogen compounds. so the answer is all the above i hope this helps
