They found that difference occurs in the speed of both sound and charges occur due to the difference in the type of medium.
Sound and charges needs specific medium for faster movement i.e. sound moves faster in solid as compared to liquid and gas whereas charges moves faster and easily in gold due to lower resistance which is followed by copper. Sound can move from solid, liquid and gases whereas charges move only in solid metal in which free electrons are present. The speed of sound and flow of current are affected due to difference in the arrangement of atoms in solid, liquid and gas.

Answer: Explanation:
When supply and demand for a product increase simultaneously, we cannot predict the market clearing price, but know that the equilibrium quantity will increase.
NB: We cannot predict the market clearing price because no adequate information such as government policy is provided. such information would likely affect the market clearing price either positively or negatively.
P.S: This is a business question.
Answer:
24 molecules of phosphorus trichloride can be formed
Explanation:
Based on the equation:
P4(s) + 6Cl2(g) → 4PCl3
<em>1 mole of P4 reacts with 6 moles of Cl2 to produce 4 moles of PCl3.</em>
<em />
When 10 molecules of P4 react, 60 molecules of Chlorine are needed. As there are just 36 molecules, Cl2 is limiting reactant.
If 36 molecules of chlorine are added, molecules of PCl3 produced are:
36 molecules Cl2 * (4 PCl3 / 6 Cl2) =
24 molecules of phosphorus trichloride can be formed
