If the rate law for a reaction A → P is rate = 3.37x10-3 M^-1 min-1 [A]^2 and the initial concentration of a is 0.122 M, calcula
DedPeter [7]

Rate = 3.37x10-3 M^-1 min-1 [A]^2 and the initial concentration of a is 0.122M.

A rate law indicates the rate of a chemical response depends on reactant concentration. For a response inclusive of the price regulation commonly has the form rate = ok[A]ⁿ, in which okay is a proportionality constant known as the fee regular and n is the order.

The charge of a chemical response is, perhaps, its maximum crucial asset because it dictates whether or not a reaction can arise all throughout an entire life. knowing the charge regulation, an expression concerning the price to the concentrations of reactants can assist a chemist to modify the response conditions to get an extra suitable rate.

half-life is the time taken for the radioactivity of a substance to fall to 1/2 its authentic cost whereas implies existence is the common life of all the nuclei of a particular risky atomic species.

What is the pH of KOH solution that has H+= 1.87 x10^-13
kakasveta [241]
The pH of a solution is calculated as pH = -log[H+], where [H+] is the concentration of H+ ions. Based on the given concentration in the problem,
pH = -log(1.87 x 10^-13 M) = 12.73
Therefore, the pH of the solution is 12.73, and this implies a strongly basic solution.

How do you measure moles
wlad13 [49]

Answer:

Answers may vary

Explanation:

Mol is the amount of molecules in something. Mol are similar to donuts, if you have a dozen of something you have 12 of them. If you have a mol of Hydrogen gas you 6.02•10^23 molecules of Hydrogen gas. If you are taking a chemistry class you will probably receive questions involving converting grams to mol and vice versa.

Converting Grams to Mol:

grams of x•(1/molecular mass of x)

note: you can find molecular mass of x by looking at the masses of the elements you need to add up in the periodic table

Converting Mol to Grams:

mol of x•(molecular mass of x)

Why would heating up the human body be a bad choice for causing a chemical reaction?
Furkat [3]

Answer:

Explained below

Explanation:

The human body has a normal core temperature of around 37°C to 38°C.

Now, if it is heated up to say 39° to 40°C, fatigue will start to set in and the brain begins to tell the muscles to slow down.

If it's now heated to higher temperatures above above 41°C, the body will begin to experience heat exhaustion and therefore will start to shut down.

Due to this process, the body can't even sweat at that stage because blood flow to the skin will stops thereby making the body feel cold and clammy. Thus, chemical processes/reaction in the body will begin to be affected and the cells inside the body will start to deteriorate and thus there is now a huge risk of having multiple organ failure.

Agents that antagonize the effects of acetylcholine are called __________.
fenix001 [56]
Agents that antagonize the effects of acetylcholine are called anticholinergic. 
<span>Anticholinergic blocks this neurotransmitter acetylcholine within the nervous system, by deactivating nerve impulses as a result of the binding of this neurotransmitter so that it cannot reach its receptor in nerve cells.</span>
