The concentration of CH3OH in the solution is 2.18M
HOW TO CALCULATE MOLARITY:
- The molarity of a solution can be calculated by dividing the number of moles by its volume as follows:
- Molarity {M} = no. of moles (mol) ÷ volume (L)
- According to this question, 35.0 g of CH3OH (MM = 32.0 g/mol) are dissolved in 500.0 mL of solution. The number of moles of methanol is calculated as follows:
no. of moles = 35g ÷ 32g/mol
no. of moles = 1.09mol
- Molarity = no. of moles ÷ volume
Volume = 500mL = 0.500L
Molarity = 1.09mol ÷ 0.500L
Molarity = 2.18M
Therefore, the concentration of CH3OH in the solution is 2.18M

B Is the answer djdkekksksksklsls
Answer:
Option A, Acquisition
Explanation:
The first stage of learning is known as acquisition. It causes establishment of responses by pairing of Neutral stimulus, conditioning and un-conditioning stimulus. Once the association between a neutral stimulus and conditioned stimulus is established, the responses are acquired.
For example – If a bird is trained to pick a key whenever there is a sound of a bell, then after certain period of time an association will be established between the “ringing of bell” and “picking up of key” activity. Therefore, whenever the bird will hear the ringing sound it will search for key to be picked.
Thus, option A is correct.
The impact on the human health as we try to stay ahead of the evolutionary process is actually very bad. It is a fact that the humans are living much longer nowadays than ever before, with the main reasons for that being the well developed medicine and healthcare, much better standard of living, and having less riskier jobs. On the other hand, the human health, without being treated, is actually at an all time low. The immune system is much weaker than it has been, with the main reason being the isolation of the outside world and the higher level of hygiene. The allergies are becoming an ever growing problem because of this, as the immune system doesn't even recognize certain outside bodies are they an enemies or not. The constant radiation for numerous sources has caused development of numerous diseases. The old age has increased the percentage of diseases such as cancer, Alzheimer, Parkinson, or sclerosis. The less active life-style and food over saturated with fats and sugars has caused numerous health problems as well. All in all, the human health has become dependent on the pharmacy and its products, and without it it will suffer badly.
