Answer:
rarely equals the theoretical yield
Explanation:
The actual yield is the result obtained from the experiment while the theoretical yield is the result obtained from our calculations. The actual yield of a chemical reaction rarely equals the theoretical yield because some of the amount are loss during the process.
<u>Answer: </u>The correct answer is Option A.
<u>Explanation:</u>
The molecule given in the question is HCl which forms a polar covalent bond.
A polar bond is defined as the bond present between two elements with different electronegativity value. The element which has higher electronegativity value, attracts the shared pair of electrons towards itself and forms a dipole. A polar molecule is dissolved more in a polar substance than in non-polar substance.
In the given compound, the electronegativity of chlorine is more than hydrogen and attracts the shared pair of electron more towards itself and hence is a polar molecule.
A non-polar bond is defined as the bond which is formed between the elements having same electronegativity value. No dipole is created in these type of bonds. Here, the electrons are shared equally.
From the above information, the correct answer is Option A.
Answer: Plate movement is thought to be driven by a combination of the motion of the seafloor away from spreading ridges due to variations in topography and density changes in the crust.
