M(C2H2O)= 12.0*2 +1.0*2 +16.0 = 42 g/mol is a molar mass for empirical formula.
120.6g/mol/42g/mol ≈ 3
So, empirical formula should be increased 3 times,
and molecular formula is C6H6O3.
Answer is D.
Answer:
A
Explanation:
I believe it is negative 1.
BF3 .... BP = −100.3 °C
<span>RbCl ..... solid </span>
<span>CH3SCH3 ..... BP = 35-41 °C </span>
<span>SbH3 .... BP = −17 °C </span>
<span>SiS2 ..... solid </span>
<span>Ethanol solid --> ethanol melts --> ethanol liquid </span>
<span>-135C ---------------> -114C --------------> -50C </span>
<span>............ ΔT = 21C ....... ....... ΔT = 64C </span>
The answer is the coefficient is "1".
C₅H₁₀, now you see that there is no number with this and when there is no number or digit, it means the coefficient is one.
we use the coefficients to balance the equation of the reaction in such a way that number of the atoms of the elements in the reactants are equal to the number of atoms of different elements in the product, so that both sides are equal and balanced.
