Someone please help: 5.2cm^3 of gaseous hydrocarbon were exploded in excess oxygen. After cooling to the original room temperature and pressure a contraction in volume of 15.6cm^3 was observed. A further contraction of 10.4cm^3 was noted after treatment with concentrated KOH. What is the molecular formula for the hydrocarbon?

Explain that newton first law,second law and third law of motion?

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?
