Answer:
Examples of compounds that contain only covalent bonds are methane (CH4), carbon monoxide (CO), and iodine monobromide (IBr). Covalent bonding between hydrogen atoms: Since each hydrogen atom has one electron, they are able to fill their outermost shells by sharing a pair of electrons through a covalent bond.
Explanation:
a heterogeneous mixture is simply any mixture that is not uniform in composition , it's a non-uniform mixture of smaller constituent parts and maybe D
Answer: A heating curve graphically represents the phase transitions that a substance undergoes as heat is added to it.
The plateaus on the curve mark the phase changes. The temperature remains constant during these phase transitions.
Water has a high boiling point because of the strong hydrogen bonds between the water molecules; it is both a strong hydrogen bond donor and acceptor.
The first change of phase is melting, during which the temperature stays the same while water melts. The second change of phase is boiling, as the temperature stays the same during the transition to gas
Explanation:
Answer:
212.304 grams
Explanation:
similar to your other question, use the same formula
q=mCpΔT
23617=m(4.182)(46.6-20)
23617=111.2412m
m=212.304g
