Answer:
2.8248 g
Explanation:
First, consider the balanced chemical equation:
Then we calculate the number of moles in 4.11 g of citric acid:
n(citric acid)=
According to the balanced reaction, one mole of citric acid produces 3 moles of carbon dioxide. That's 3 times the number f moles of citric acid. So we will do the same with the available number of moles of citric acid.
so n(carbon dioxide) = 0.0214 mol*3=0.0642 mol
mass(carbon dioxide)= mass*molar mass=0.0642 mol* 44g/mol
= 2.8248 g
Answer:
The correct answer is C (sodium chloride which is a salt human)
Explanation:
The sodium chloride whose formula is NaCl, corresponds to an ionic compound formed by a metal (Na) and a nonmetal (Cl). It corresponds to an inorganic substance, since it does not have carbon. Organic compounds are those that have carbon (example: glucose, methane, etc.)
Answer: the answer is B
Explanation: i go to connexus i had this question
Talk to them and listen to each other. if they aren’t ready to talk, give them space. once both of you are ready, you can make up and forgive each other. don’t bother them by asking a lot of questions and forcing them to talk to you. and if they’re doing that, tell them you need time to think. just be sure to talk to them, listen, and understand. tell each other both sides of the stories. of course, different situations can require different solutions. so resolve it when it’s time :)
