<span>The
Pair Of Compounds that Are Isomers are CH3COCH3 and CH3CH2CHO. The answer is
number 4. Isomers have the same formula but different structures. In number 4,
both compounds contains three carbon atoms, one oxygen and 6 hydrogen atoms
that makes them isomers.</span>
Answer:
Distance, some kind of distance or length.
Explanation:
Answer:
The answer is 5.10
Explanation:
<h3><u>Given</u>;</h3>
<h3>
<u>To </u><u>Find</u>;</h3>
We know that
pH + pOH = 7
pOH = 7 – pH
pOH = 7 – 1.90
pOH = 5.10
Thus, The pOH of the solution is 5.10
No, because 40 miles is the same as nearly 25 km/h.
CaCO3(s) ⟶ CaO(s)+CO2(s)
<span>
moles CaCO3: 1.31 g/100 g/mole CaCO3= 0.0131 </span>
<span>
From stoichiometry, 1 mole of CO2 is formed per 1 mole CaCO3,
therefore 0.0131 moles CO2 should also be formed.
0.0131 moles CO2 x 44 g/mole CO2 = 0.576 g CO2 </span>
Therefore:<span>
<span>% Yield: 0.53/.576 x100= 92 percent yield</span></span>
