The correct option is C. The paragraph is biased, not taking into consideration the other great inventions that have been made. The information given are vague, over generalised, without providing any evidence to support its claims. They are blanket statementso and are not useful at all.
0.2842 M<span> * 114 </span>ml<span> = M2 * (114+137) </span>ml<span> ... 228 </span>mL<span> = 0.228 L 114 </span>mL<span> ... </span>Final concentration<span> (or molarity) = (0.0324 moles) / [(0.114 L + 0.137 L)]</span>
I don't know where the question is, but I will assume that this is a True or False statement.
If that is the case, this statement is false.
You have the equation Q = mc<span>ΔT.
The statement states that if m is doubled, c is doubled as well. This is incorrect, since the specific heat value cannot be changed because it is attributed to the specific substance. If m doubles with the same substance, assuming a constant change in temperature, the only thing that can change is Q, which is the heat energy gained or lost from the substance.</span>
Bohr's model was known as the solar system model. This is because he envisioned electrons as orbiting the nucleus in circles, and the force that kept that together was electrostatic attraction. This is analogous to the solar system model, where planets orbit the sun in a manner (although not in a circle) controlled by gravity.
Im pretty sure this answer is true
