About 1.2 times ten to the 24th power. This is so much more money than has ever existed that it's almost meaningless. (To give some perspective, there's about 1.2 times ten to the 12th dollars in circulation right now; if you piled all of it up, it would take a trillion such piles to make two moles of dollars.)
There are 8 zeroes in the number for 2 million dollars
5 dollars, 2 cents.
Funny pennies make two dollars
5 zeros for the dollars, 2 for the cents
One 10 dollar, 2 five dollars, 5 two dollars, and 10 one dollars.
2 moles of Ca and 4 moles of OH
true
This reaction is:2 Al + 2 H2O + 2 NaOH = 2 NaAlO2 + 3 H2From 4 moles of Al 6 moles of hydrogen are obtained.
2 moles, if you can find the proper catalyst, or set of reactions to complete the reaction.
It takes 2 moles of NO to form 2 moles of NO2, so to form 4.67 moles of NO2 you would need 4.67 moles of NO.
The answer is 3 moles of Cu)NO3)2..
2.60 moles There are 2 moles of K in K2SO4. the total moles times two (1.3 x 2) is 2.60 moles.
12 moles
The answer is 2 moles.
4 moles also 2 moles of oxygen will be consumed
5 moles RbNO3 (3 moles O2/2 moles RbNO3) = 7.5 moles oxygen gas produced
2 moles C8H18 (18 moles H/1 mole C8H18) = 36 moles of hydrogen =================
