answer= 0.912 L or 912 mL
M(KClO3) = 122.55 g/mol
3.00 g KClO3 * 1 mol/122.55 g = 3.00/122.55 mol =0.02449 mol
2KCIO3(s)=2KCI(s) + 3O2(g)
from reaction 2 mol 3 mol
given 0.02449 mol x
x = 0.02449*3/2 =0.03673 mol O2
T = 24 + 273.15 = 297.15 K
PV = nRT
V= nRT/P = (0.03673 mol*0.082057 L*atm/K*mol*297.15 K)/0.982 atm =
= 0.912 L or 912 mL
Answer: England and Canada
Explanation:
Yes
Answer:
ethyl methyl ether
Explanation:
when naming ethers name the alkyl rings, in this case we have methyl and ethyl( make sure they are in alphabetical order) followed by the word ether, so it becomes ethyl methyl ether
Answer:
it gains 2 electrons
Explanation:
atoms want to be more stable, for oxygen it's number is 8, 2 less than the stable ring of 10. and hydrogen has a single electron, 1 less than the stable ring of 2. so oxygen takes 2 electrons 2 make it stable and hydrogen becomes attatched to the oxygen atom to form a covalent bond
Answer:
Diatomic molecules consist of two atoms bonded together. In contrast, monatomic elements consist of single atoms (e.g., Ar, He). Many compounds are diatomic, such as HCl, NaCl, and KBr. Diatomic compounds consist of two different elements. There are seven pure elements that form diatomic molecules.
