Thoughts on Today's Verse... Christ died for the ungodly. Christ died for me. Without his sacrificial death, without God's grace, I am powerless to save myself or make myself righteous. Jesus did for me what I could not do and paid off my debt to sin which I could not pay. He did it for me; not because I was good enough to be worthy of his death, but because I couldn't be worthy without him.

Which statement justifies that phosphine (ph3) is a polar molecule?

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?

Calculate the percent composition by mass of each element in al(oh)3. use at least three significant figures.
