how many atoms are present in 80.0 mol of zirconium?

how many moles of platinum are equivalent to 1.20 x 10^24

I have 3 questions that I am uncertain about. 1) what determines the order in which the coumponent elements of binary molecular compounds are written? 2) Name the Binary compound according to the prefix system for As2O5 3) write the formula for each of th...

can u see if i did this right because i highly doubt i did name each of the following acids: a) HF i put Hydrogen fluoride b) HBr i put hydrogen bromide c) HNO3 don't know this one d) H2SO4 didn't know this one either e) H3PO4 i put Hydrogen phosphoric

name the following compounds and tell what type of compound they are (binary ionic, ternary ionic or binary molecular) FeBr3, b) CBr4 and c) Na2Cr2O7

let f(x)= 3x-7 and g(x) = 4x-5. Find (f ° g)(-1)

confrused with this one too let f(x)=x^2+6 and g (x) =4x-5 find (f ° g)(-7)

confrused with this one too let f(x)=x^2+6 and g (x) =4x-5 find (f ° g)(-7) still don't get it and no one responds to my replys after the tutors assist

V90x^26/V2x a) 3x^12 V5x bV18x^25 c) 5xV3x^12 d none of there *** the V is the real number root.. aka 2nd x2 on the graphing calc

well for a i put iron brinide and that it was binary ionic.. b i put carbom bromide and c i put sodium chromium but i didn't thow what typoe of compounds they were

i got -55/7 is that right?

according to my multiple choices its a fraction a -55/7 b 384/7 c 295/49 d 63/55

f(x)=x^2+6 and g (x) =x +8/xfind (f ° g)(-7) yep there was sorry

ok then the other one is right im sorry and thank you
