Convert all the fractions so that they all have the same denominator (the number below the line). That way, you can tell how big they are relative to one another just by looking at the numerator (the number above the line). (#1.) 2/5, 1/10, and 3/20 can a...

For mole composition, you would convert each to moles and then determine the percent of each to the total.

First, start with a balanced equation. Then, use stoichiometry to determine the limiting reactant and then how much product (AgCl) is produced. Use this (theoretical yield) and the actual yield (33.6g) to determine the percent yield.

a. ) The bond length is the internuclear distance. b. ) The covalent bond is a region of high electron charge density between two atoms. c. ) Hybrid orbitals are combinations of atomic orbitals. d. ) There are the same number of hybrid orbitals produced a...

let the width be x and the length be y we know xy = 6 and x^2 + y^2 = (2ã5)^2 = 20 Perimeter = 2(x+y) from algebra we know (x+y)^2 = x^ + 2xy + y^2 but we know the values on the right side, so (x+y)^2 = 20 +12=32 then x+y = ã32 and the perimeter is 2ã3...

it is: -y/x* (2x+y)/(2y+x) let me now if you need more details.

27 / (5+4) * 19 = 27 / (9) * 19=3*19=57. Mom is right.

15 years ago

You are correct. I had the EXACT same Physics problem and got them correct.

sorry i mean which reactant

i got the mass of aluminum chloride to be 42.7

That would make more sense! Many thanks
