35 POINTS Consider the following reaction:
4P + 502 → P4010
The percent yield of P4010 when 6.20 g of phosphorus burns in
excess oxygen is 67.0 %.What is the actual yield of P4010?
(Molar mass of P = 31.0 g/mol, molar mass of P4010 = 284
g/mol) (Round your answer 3 significant figures e. g. 5.62)
grams

0.09 moles of sodium sulfate in 12 ml of solution

The solid xy decomposes into gaseous x and y: xy(s) m x(g) + y(g) kp = 4.1 (at 0 °c) if the reaction is carried out in a 22.4 l container, which initial amounts of x and y will result in the formation of solid xy?

Consider a culture medium on which only gram-positive organisms such as staphylococcus aureus colonies can grow due to an elevated nacl level. a yellow halo surrounds the growth, indicating the bacterium fermented a sugar in the medium, decreasing the ph as a result and changing the color of a ph indicator chemical. this type of medium would be referred to as a differential and enrichment culture.
