Explanation:
Yes, because gravity is part of chemistry because chemistry is about physical changes and etc so it has to be about gravity.
Molecules comes first since they are the smallest. Then atoms. Then blood cells. Then the heart I think, and then the person.
Answer:
dude did you not pay attention in science the answer is 18- n 20- p 18-e
Explanation:
The balanced equation for the above reaction is as follows
CaCO₃ + 2HBr ---> CaBr₂ + CO₂ + H₂O
stoichiometry of CaCO₃ to HBr is 1:2
number of moles of CaCO₃ reacted - 5.64 g / 100 g/mol = 0.0564 mol
according to molar ratio
number of HBr moles - 0.0564 mol x 2 = 0.1128 mol
number of HBr moles in 250.0 mL - 0.1128 mol
therefore number of HBr moles in 1000 mL - 0.1128 mol / 250.0 mL x 1000 mL = 0.4512 mol
molarity of HBr - 0.4512 M
