Answer: The planets revolve around the sun.
Explanation: Its common knowledge...
At room temperature, it is a solid state of matter. hope this helps, have an amazing day :)
1. 2Al(s)+6HCl(aq)⇒2AlCl₃(aq)+3H₂(g)
2. 2AgNO₃ (aq) + Cu (s)⇒Cu(NO₃)₂ (aq) + 2Ag (s)
3. 2C₃H₈O(l) + 9O₂(g) ⇒ 6CO₂(g) + 8H₂O(g)
<h3>Further explanation</h3>
There are several reactions that can occur in a chemical reaction: single replacement, double replacement, synthesis, decomposition or combustion, etc.
1.Al(s)+HCl(aq)⇒AlCl₃(aq)+H₂(g)
type : single replacement
balance :
2Al(s)+6HCl(aq)⇒2AlCl₃(aq)+3H₂(g)
2. AgNO₃ (aq) + Cu (s) ⇒ Cu(NO₃)₂ (aq) + Ag (s)
type : single replacement
balance :
2AgNO₃ (aq) + Cu (s)⇒Cu(NO₃)₂ (aq) + 2Ag (s)
3. C₃H₈O + O₂ ⇒ CO₂ + H₂O
type : combustion of alcohol
balance :
2C₃H₈O(l) + 9O₂(g) ⇒ 6CO₂(g) + 8H₂O(g)
Answer:
a. CH4 is only held together by London dispersion forces since any dipoles cancel out due to symmetry. On the other hand H2O has strong hydrogen bonds
b. PH3 has dipole-dipole forces while NH3 is held together by stronger hydrogen bonding
c. C2H6 and C3H8
. Both substances are held together by London dispersion forces since any dipoles cancel out due to symmetry. However C3H8 has the stronger London dispersion forces of the two because it is a larger molecule,
d. BH3 is held together by London dispersion forces since any dipoles cancel out due to symmetry while OF2 is held together by stronger dipole-dipole forces
Answer:
A substance with a high activation energy is expected to have a slow reaction rate.
