The diagram shows an animal cell.

Chemistry
1 answer:
LenKa [72]3 years ago
8 0

Answer:

X  

Explanation:

Assume your diagram is like the one below.

X represents a mitochondrion.

That's where the Tricarboxylic Acid Cycle converts a single glucose molecule into six molecules of CO₂.

W is wrong. It represents a vacuole, which can store both nutrients and waste products for later elimination.

Y is wrong. It represents the nucleolus, which plays a critical role in the synthesis of ribosomes.  

Z is wrong. It represents the cytoplasm, which is where cell processes like glycolysis and protein synthesis take place.

Identify the intermolecular forces present in each of these substances. h2o co hcl co2
Katyanochek1 [597]
There are 4 general types of intermolecular forces: electrostatic force, London dispersion force, Dipole-Dipole force and Hydrogen Bonding.

Electrostatic force is the force between opposite charges; London dispersion force is common for nonpolar molecules, dipole-dipole forces common in polar molecules while hydrogen bonding is for molecules having either O-H, N-H and F-H bonds.

H₂O: Since water has 2 O-H bonds and it is polar, the intermolecular forces are hydrogen bonding and dipole-dipole forces

CO: It is polar sothe answer is dipole-dipole forces.

HCl: This is also a polar molecule, so dipole-dipole forces.

CO₂: This is a nonpolar molecules, so the answer is London dispersion forces.

"sticky ends" allow dna fragments to be spliced into vectors by what type of bonding?
kompoz [17]
<h3><u>Answer;</u></h3>

Covalent bonds

<h3><u>Explanation;</u></h3>
  • <em><u>Sticky ends refers to the bases of DNA that are unpaired because of the action of the restriction enzymes.</u></em>
  • <em><u>Sticky ends are referred to as sticky because they have complementary bases.</u></em>  Sticky ends allow base pairing through covalent bonds between the bases.
  • The action of restriction enzymes results to overhangs, or the so called sticky ends which allow perfect base pairing, where Adenine (A) pairs with Thyamine (T) and Guanine (G) pairs with cytosine (C), as a result of covalent bonding.

A galvanic cell at a temperature of 25.0°C is powered by the following redox reaction:
soldi70 [24.7K]

Answer:

2.01V ( To three significant digits)

Explanation:

First we show the standard reduction potentials of Cu2+(aq)/Cu(s) system and Al3+(aq)/Al(s) system. We can clearly see from the balanced redox reaction equation that aluminium is the anode and was the oxidized specie while copper is the cathode and was the reduced specie. This observation is necessary when substituting values of concentration into the Nernst equation.

The next thing to do is to obtain the standard cell potential as shown in the image attached and subsequently substitute values of concentration and standard cell potential into the Nernst equation as shown. This gives the cell potential under the given conditions.

What is hydrogen ion concentration of an acid solution whose PH is 3.4?​
meriva
It’s easy, if the PH of any acidic solution = -Log[H+], where [H+] is hydrogen ion concentration, multiply each term by (-1) then raise each term as a power to (10), so it will become like this:-
[H+] = 10^(-PH)

What is the pOH of a 0.0010 M solution of calcium hydroxide (Ca(OH)2)
inysia [295]

Answer: The pOH is: " 2.40 " .

__________________________________________________________

The pOH value of a 0.0010 M solution of calcium hydroxide;

Ca(OH)₂ ; is:

__________________________________________________________

" 2.40 " .

__________________________________________________________


Explanation:

___________________________________________________________

Calculate the pOH of a 0.0010 M solution of Ca(OH)₂ .


Note that:

"M" represents the concentration in "Molarity" ;

(that is; "moles of solute per Liter of solution" ; or, "mol / L " } ;


and that for our purposes, anything notes in "brackets" refers to "concentration"; in "M" {"Molarity" ; as explained above.}.

Note that "calcium hydroxide", that is; " Ca(OH)₂ " ;

→ dissociates into the following ions, as follows:


→ Ca(OH)₂ → Ca²⁺ + 2 OH⁻ ;

Therefore, the [OH⁻] equals: {2 * 0.0010} M = 0.0040 M .


For every Ca(OH)₂ you produce 2 OH⁻ .

<u>Note</u>: pOH = - log [OH⁻] ;


pOH = - log ( 0.0040) = 2.3979400086720375 ;


→ round to: " 2.40 " .

__________________________________________________________

Answer: The pOH is: " 2.40 " .

__________________________________________________________

The pOH value of a 0.0010 M solution of calcium hydroxide; Ca(OH)₂ ; is:

" 2.40 " .
