Answer:

pOH= 8.4

Explanation:

pH+pOH=14

5.6+pOH= 14

pOH= 14-5.6= 8.4

How do ethics affect scientific research
densk [106]

Answer: Ethical concerns affect scientific research when scientists or groups of scientists let their personal bias or political persuasions affect the research being conducted.

Help me, I’m bad a science.
Sauron [17]

Answer:

Removing the worms is they first key to overcoming this problem. Thus you should ensure that the worms have not spread throughout the house/facility, or caused more damage.

Secondly, you should replace the pipes taht the worms got into, or clean them at most. If it’s simply worm droppings then just clean it, but if it’s more and worse than that alike slime then it is best to remove and replace it.

the only way the worms escaping could affect something is if they decontaminated it, or alas ate or destroyed it. Other than that if they died you could simply replace them, but e things cannot be replaced

How do you do problem bii??
Advocard [28]

Answer:

Explanation:

Trick question. The cathode is where the reduction reaction takes place. The reduction reaction is the gain of electrons.

Pb+2 + 2e^- ===> Pb        The eo for that is - 0.126.

The minus sign indicates that the Pb^2+ is not overjoyed at taking on those two electrons. If it had a say in the matter, it would rather be giving up electrons. In other words, it would rather be the oxidizing equation which would look like this

Pb ===> Pb+2 + 2e^- and the oxidizing potential would be eo = + 0.126

That's what moving right and moving left means. If the eo is - then the preferred reaction is the opposite one.

This is a real language problem and if Znk answers you can take his answer to the bank.

A gas has a volume of 25.6 L at a temperature of 278 K. What will be the new temperature, in C, if
Inessa05 [86]
<h2>Hello!</h2>

The answer is: -97.37° C

<h2>Why?</h2>

According to the Charles and Gay-Lussac's Law we have that:

\frac{V}{T}=k

Where:

<em>v</em> is the volume of the gas

<em>t</em> is the temperature of the gas

<em>k </em>is the proportionality constant

From the Gay-Lussac's Law we also have the following relation:

\frac{V1}{T1}=\frac{V2}{T2}

Since we need to find the new temperature (T2) we can use the last equation:

\frac{V1}{T1}=\frac{V2}{T2}\\\\T2=\frac{V2*T1}{V1}=\frac{16.2L*278K}{25.6L}=175.92K

We are asked to find the temperature in Celsius degrees, so, we must convert the result (in K) to Celsius degrees:

Celsius=K-273.15=175.92-273.15=-97.37

So, the temperature is -97.37° C

Have a nice day!

What is the chemical formula for the conjugate acid of the base trimethylamine (ch3)3n?
EleoNora [17]

A conjugate acid is given by the acid-base theory of Bronsted–Lowry. The conjugate acid of a weak base, trimethylamine is ((CH₃)₃NH⁺) trimethylammonium ion.

<h3>What is a conjugate acid?</h3>

A conjugate acid is a compound that has been formed when a base accepts the hydrogen or the proton ion from an acid. It can also be said that a hydrogen ion is added to a base.

The conjugate acid differs from the base by the addition of one proton ion to it. The reaction of a weak base, trimethylamine can be shown as,

(CH₃)₃N(aq) + H₃O⁺(aq) ⇌ (CH₃)₃NH⁺(aq) + H₂O(l)

Here, the trimethylamine compound has accepted a proton from hydronium to produce a conjugate acid, trimethylammonium cation, (CH₃)₃NH⁺.

Therefore, trimethylammonium (CH₃)₃NH⁺ is the conjugate acid of trimethylamine.
