Explanation:
We know that surface area is an important determinant factor in the study of reaction rate. This is the reason why finely divided marble chips react faster than lumps of marble in the reaction between marble chips and dilute HCl.
Now imagine that i have a lump of marble and i have finely divided marble. Then i also have a solution of 0.5 M dilute HCl. If i introduce 1g of the lump of marble into 250 ml solution of the 0.5 M HCl in one beaker and introduce 1g of finely divided marble into another 250 ml solution of 0.5 M HCl in a separate beaker, we will notice that the finely divided marble chips reacts faster as evidenced by the quicker effervescence of CO2 gas from the later compared to the former.
Hence, smaller marble chips reacts faster with dilute HCl than a lump of marble.

Explanation:
1. The Ketone was not sown in the question but i can give you a general idea of how to calculate its molecular weight. A ketone has a general molecular formula of CnH₂nO.
The molecular weight is calculated knowing that the relative atomic mass of carbon is 12, that of hydrogen is 1 while that of oxygen is 16.
Hence from the general molecular formula, the molecular weight of any ketone is calculated from; n(12) + 2n(1) + 16. Where n represents the number of atoms of each element in the ketone.
2. Sublimation of dry ice occurs when the molecules in dry ice absorb sufficient energy in the form of heat such that they now have enough energy for some molecules to overcome the inter molecular forces acting in the solid crystal and transform directly into the vapor phase. This process is endothermic.
3.
cyclohexane and CH2Cl2 molecules are held together by dispersion forces.
CH3CH2OCH2CH3 and CH3CN are polar molecules held together by dipole-dipole forces.
The false statement is that the reaction of 17 g of NH3 will produce 27 g of water. (Option D)
<h3>What is a balanced reaction equation?</h3>
A balanced reaction equation is one in which the number of atoms of each element on the right hand side of the equation is equal to the number of atoms of the same element on the left and side of the reaction equation.
The equation of the reaction is 4 NH3 + 5 O2 → 4 NO + 6 H₂O. The number of atoms of each element on both sides are equal.
Hence, the statement that is false from the reaction equation is; "the reaction of 17 g of NH3 will produce 27 g of water".
