Answer:
5
Explanation:
Balance the equation in order of C,H,O and then you should be able to find the coefficient
Answer is:<span>the yield is 50%.
</span>
Chemical reaction: C + O₂ → CO₂.
n(C) = 0.3 mol; amount of substance.
n(O₂) = 0.3 mol.
From chemical reaction: n(C) : n(CO₂) = 1 : 1.
n(CO₂) = 0.3 mol.
M(CO₂) = 44 g/mol; molar mass of caron(IV) oxide.
m(CO₂) = n(CO₂) · M(CO₂).
m(CO₂) =0.3 mol · 44 g/mol.
m(CO₂) = 13.2 g; mass of carbon(IV) oxide.
the yield = 6.6 g ÷ 13.2 g · 100%.
the yield = 50%.
Answer:
3Mg(OH)2 + 2H3PO4 = Mg3(PO4)2 + 2H3O
Explanation:
Answer:
From the water to the dry ice
Explanation:
The energy is transferred from the water to the dry ice because the water is warmer than the dry ice.
