Question
Which statement is not correct regarding the molar volume of a gas? O It varies according to the molar mass of the gas. O It is 22.4 L for an ideal gas at STP. O The temperature and pressure must be specified. O All three of these statements are correct O None of these three statements is correct. QUESTION 9 2 pointsSve Answer A neurotransmitter is a chemical that O transfers information between adjacent neurons. O speeds up a chemical process without being consumed. O allows regeneration of injured brain and nerve cells O allows genetic information to be sent from parent to offspring. O interferes with the function of hormones. QUESTION 10 2 points Save Answer My last camping trip involved several hours of driving uphill along narrow winding roads, and then I had to set up camp and find firewood as night was falling. The next morning, I mixed a bowl of pancake batter, turned away to tend the fire, and looked back to find most of the batter on the table, but the bowl standing the way I left it. Which statement best explains what happened? O Because the morning air in the woods was cool, it was less dense, allowing the batter to rise more than I expected. O A very quiet, tidy wild animal dumped it but was frightened away when I turned. O I made a mistake in measuring the amounts of liquid and pancake mix. O The batter rose very quickly and more than expected because of the lower atmospheric pressure at the higher altitude. O None of these is a reasonable explanation.Explanation / Answer

Answer is "It varies according to the molar mass of the gas?"
The most common example is the molar volume of a gas at STP (Standard Temperature and Pressure), which is equal to 22.4 L for 1 mole of any ideal gas at a temperature equal to 273.15 K and a pressure equal to 1.00 atm.

Answer is "transfer information between adjacent neurons."
Neurotransmitters are endogenous chemicals that enable neurotransmission. It is a type of chemical messenger which transmits signals across a chemical synapse, such as a neuromuscular junction, from one neuron (nerve cell) to another "target" neuron, muscle cell, or gland cell.
Chemical synapses are biological junctions through which neurons' signals can be exchanged to each other and to non-neuronal cells such as those in muscles or glands. Chemical synapses allow neurons to form circuits within the central nervous system.

Answer is "The batter rose very quickly and more than expected beacuse of the lower atmospheric pressure at the higher altitude."
