Prove trig identity
randy re check the question and use brackets to identify do u mean secant squared? or secant to the power of 2x-1
-3,-2,4 use the number line
what would be a diagram that we can use to idenitify an unknown substance using electrochemical data. we have a reduction table and ksp values and we also that the substance is either bromine or iodine
6y+-4x + y -x 7y -5x
7z + 5 = 21 7z=21-5 7z=16 z=16/7
factor out 5 u get 5(4x^2+8x +3) = 0 5(4x^2+2x+6x+3)=0 5(2x(2x+1)+3(2x+1))=0 5(2x+1)(2x+3)=0 x=-1/2 or x=-3/2
Excess fluorine, F2(g), reacts at 150°C with bromine, Br2(g), to give a compound BrFn. If 423 mL Br2(g) at 150°C and 748 mmHg produced 4.20 g BrFn, what is n? Predict the shape of this molecule using the VSEPR model.
A molecular compound is composed of 58.8% Xe, 7.2% O, and 34.0% F, by mass. If the molecular weight is 223 g/mol, what is the molecular formula? Draw the correct Lewis structure. Predict the molecular geometry using the VSEPR model.
A gaseous compound has the following composition by mass: C, 25.0%; H, 2.1%; F, 39.6%; O, 33.3%. Its molecular weight is 48 g/mol
