Suppose total world energy consumption of fossil fuels, equal to 3×1017 kj/yr, were to be obtained entirely by combustion of petroleum with the approximate chemical formula c2h3. combustion of petroleum releases about 43×103 kj/kg. estimate the emissions of co2 in kg per year.

Calculate the molarity of 48.0 ml of 6.00 m h2so4 diluted to 0.250 l .

Which position represents spring in the southern hemisphere? a) b) c) d)

Someone offer some answers to this, i will give 98 coins and mark as brainliest! i will put the rest of the lab down in the comments,solutions pre-lab questions: in this lab, you will make fruit drinks with powdered drink mix. complete the pre-lab questions to get the values you need for your drink solutions. calculate the molar mass of powered fruit drink mix, made from sucrose (c12h22o11).using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 m solution of 100 ml. (hint: use molarity = to find the moles of drink mix, then convert moles to grams using a mole conversion.)what mass of powdered drink mix is needed to make a 0.5 m solution of 100 ml?
