When gaseous nitrogen and gaseous hydrogen are reacted at high temperatures in the presence of a catalyst, ammonia (and no other product) is formed. If a chemical plant has to synthesize 450 kg of ammonia, what mass (in kilograms) of hydrogen has will be required, assuming 100% yield? (Use molar masses: hydrogen = 10 and nitrogen = 14,0 g/mol.) Give your answer to 2 significant figures. In the precipitation reaction: AlCl3(aq) + 3 NaOH(aq) – AKOH)3(s) + 3 NaCl(aq), what volume of 0.200 M NaOH(aq) solution would be required to react completely with 25.0 mL of a 0.100 M solution of AlCl3(aq)?
a) 150.0 mL
b) 12.5 ml
c) 4.2 ml
d) 37.5 mL

Which is a difference between molecular compounds and ionic compounds? select the correct answer below: question 5 options: molecular compounds typically form between a metal and a nonmetal, while ionic compounds typically form between nonmetals. molecular compounds result from the transfer of electrons between atoms to form ions, while ionic compounds result from the sharing of electrons between neutral atoms. molecular compounds are formed of discrete, neutral molecules, while ionic compounds are formed of large repeating arrays of opposite charges. molecular compounds have high melting points and high boiling points, while ionic

Which of the dna typing techniques do you think you would choose if you had to analyze a dna sample? why?

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?
