Answer:
B
Explanation:
Coal is a non-renewable resource, so the supply can't produce faster than we can mine it.
Answer:
Cu + 2AgNO₃ → 2Ag + Cu(NO₃)₂
Explanation:
We are to give the reaction expression for this displacement reaction.
Reactants = copper and silver nitrate solution
Products = silver and copper (II) nitrate
Copper = Cu
Silver nitrate solution = AgNO₃
Silver = Ag
copper (II) nitrate = Cu(NO₃) ₂
So:
Cu + 2AgNO₃ → 2Ag + Cu(NO₃)₂
2HCl + Ca = CaCl₂ + H₂
n(HCl)=cv
n(Ca)=m(Ca)/M(Ca)
n(HCl)=2n(Ca)
cv=2m(Ca)/M(Ca)
v=2m(Ca)/{cM(Ca)}
v=2*60/{1.25*40}=2.4 L
Answer:
Covalent
Explanation:
In the carbon tetrachloride molecule, four chlorine atoms are positioned symmetrically as corners in a tetrahedral configuration joined to a central carbon atom by single covalent bonds
CO2 i think if you understand so mark me as brainliest please.
