Answer:
Most of the scientists worldwide do not accept this theory.
Explanation:
Lamarck's theory states that acquired traits can be passed on from parents to offspring. This theory can not be sufficiently substantiated by indisputable scientific evidences hence it is not accepted by majority of scientists worldwide.
Since science is empirical and the theory is mostly based on vague speculations rather than concrete evidence, it was long rejected by many biologists.
This theory suggests that all life forms will gradually evolve from simple to complex organisms while the simple organisms gradually disappear. This is not the case.
Answer:
- The room mantained at a lower temperature will contain more air molecules.
Explanation:
1) Since the two rooms are <em>connected by an open door</em>, you assume pressure equilibrium: the pressure on the two rooms is the same.
2) Since you consider <em>two equal size rooms</em>, both volumes are equal.
3) Assuming ideal gas behavior, pressure (P), temperature (T), volume (V) and number of moles (n) are related by the equation PV = nRT
4) Naming T₁ the lower temperature, T₂ the higher temperature, n₁ the number of moles of air in the room at lower temperature, and n₂ the number of moles of air in the room at higher temperature, you get:
- n₁ T₁ = n₂ T₂, or n₁ / n₂ = T₂ / T₁
5) That means that the amount of molecules (number of moles) is inversely related to the temperature: the higher the temperature the lower the number of moles, and the lower the temperature the greater the number of moles.
Hence, the answer is that <em>the room that contains more air molecules is the room mantained at a lower temperature.</em>
True- For example, woodchucks are also called "groundhogs" and "whistlepigs"; but when using the scientific name scientists know they're talking about animal.
Answer is: both reactions are exothermic.
<span>In exothermic reactions, heat is released and enthalpy of reaction is less than zero (as it show second chemical reaction).
According to Le Chatelier's principle when the reaction
is <span>exothermic heat is included as a
product (as it show first chemical reaction).</span></span>
