A neurotransmitter whose function depends on a second messenger is known as?
A neurotransmitter whose function depends on a second messenger is known as a norepinephrine. It is a hormone that is released by the sympathetic nerves and the adrenal medulla.
PH -logH plus where H plus is the hydrogen ion concentration measured in miles per liter. What is the pH of a solution whose concentration of hydrogen ions is 6.98 10-7 moles per liter?
The pH is 6,15.
Why are standard solutions used?
A solution is a homogenous mixture of two or more substances. while A solution whose concentration is known is called a standard solution.
What is positive catalyst?
A catalyst is a substance whose presence alters the rates of the reaction without themselves undergoing any permanent change in concentration or composition .
Why the sea water is blue?
the color of ocean is blue because the blue color splits more and the color of sky becomes blue and it reflects the blue color and the color of sea becomes blue
What is the pH of a solution whose hydronium ion concentration is 5.03 and nbsp and acute and nbsp10-1 M?
pH = -log[H+] The pH is equal to the negative log of the hydronium concentration, so take the -log of 5.03*10^-1 pH= -log(5.03*10^-1)
What color is a pit stop flag?
It depends on whose flag it is. But the flag has the number and the base color of the car on it.
What is the hydronium ion concentration of a solution at 298 K whose hydroxide ion concentration is 1 x 10-8?
[H3O+]*[OH-]=1.0*10-14 at 298K ,so [H3O+] = 1.0*10-14 / [OH-] = 1.0*10-14 / 1.0*10-8 = 1.0*10-6 mol/L
What is the hydronium ion concentration of a solution at 298 K whose hydroxide ion concentration is 1 x 10-8 A 1 x 10-6 B 1 x 10-7 C 1 x 10-8 x D 1 x 10-14?
The answer is A 1 x 10^(-6)
What is the molar absorption of copper-II sulfate pentahydrate whose absorbance is 0.17 at 650nm?
Depends on the length the light traveled through the solution and the solution concentration. molar absorption = absorbance/(length x concentration) length is typically in cm and concentration is typically in mol/L
Does increasing the concentration have an effect on the purity of the product?
This is a vague question since you do not identify the product whose purity you are asking about, nor do you identify the substance whose concentration we hypothetically increase.

why does the blood sugar concentration of a person whose diet is relatively low in carbohydrated remain stable.this isn't an answer!
What do you call an organism whose internal salt concentration varies with that of their environment?
An Osmoconformer
What is pH of the solution whose hydroxide in concentration is 4?
More than 7
What is the concentration of the hydroxide ions of a solution whose pH is 4.0?
1 x 104
What marine organisms whose internal salt concentration varies with that of their environment are examples of?
osmoregulators
