Chemistry masterminds! I really need your help! If 17.50 g of KClO3 were used..

THERE ISNT ENOUGH TIME >. If 17.50 g of KClO3were used in the following equation, what volume of oxygen would be produced at 25 degrees C and 744 torr pressure?-2KClO3 ---------> 2KCl + 3O2 2moles o

Chem Majors! PLEASE HELP! Consider the equation for the combustion of butane..

I cant figure this one out for my cats life :( Consider the equation for the combustion of butane: 2 C4H10(g)+13 O2(g)8 CO2(g)+10 H2O(g) What volume of oxygen at STP would be needed to completely

Chemistry geniuses! Please help!! What will be the volume of 1.00 mol H2..

10 points best answer! What will be the volume of 1.00 mol H2 and 0.750 mol He at 50OC and 2.00 atm pressure?-At 1 ATM at 0°K, 1 mole = 22.4L You have 1.75 mole, so thats 22.4 · 1.75 = 39.2L. Youve

What is the by-product of acetic acid and how are they used

this is for chem 20-Acetic acid is a weak base (hc2h3o2). that means that it produces some h+ and some c2h3o2- ions. if titrated fully, it will leave the acetic ions, resulting in a slightly basic sol

Isotopic abundance, percentage

Natural Sb consists of two isotopes, 121Sb (120.904 amu) and 123Sb (122.904 amu). Calculate the percent abundance of the heavier of the two isotopes. The solution was 121.8 = 122.904x + 120.904(1-x)

Does adding table salt to water make it boil faster

Ive always though it did, but shouldnt it slow it down? Because it raises the boiling point temperature?-NO, not at all.It raises the boiling temp slightly, so yes, it would take slightly longer for i
