what additional reaction product would result if naoh was used as a base in this reaction instead of k2co3?
Answer:
What reaction product would result if NaOH was used as a base in this reaction instead of K2CO3? If sodium hydroxide was used as the base of the reaction, then the reaction product formed would be an ethyl alcohol because it would undergo a hydrolysis reaction with addition of iodoethane
The entire carbonation reaction demonstrates how potassium carbonate (K2CO3) combines with water and carbon dioxide to create potassium bicarbonate (KHCO3) when exposed to combustion flue gases at low temperatures (40 to 80 °C) (Reaction 1)
What takes place when K2CO3 and water interact?In an extremely violent and exothermic reaction, potassium carbonate splits into potassium and carbonate ions when it interacts with water. When the ions interact, potassium oxide and carbonic acid are created.
K2CO3 come from : Potassium carbonate is a common ingredient in the manufacture of soap and glass. Additionally, it serves as a light drying agent. This substance is used as a buffering agent in numerous wine making procedures. Another usage for potassium carbonate is as a fire extinguisher.
K2CO3 created : Commercially, potassium carbonate is made by reacting potassium hydroxide with carbon dioxide:
2 KOH + CO2 = K2CO3 + H2.
K2CO332H2O sesquihydrate crystallizes from the solution ("potash hydrate").
The anhydrous salt is produced by heating this solid at 200 °C (392 °F).
It disintegrates into K2O+CO2 around 1200 C. (allreaction)
By converting carbonate into carbon dioxide and water, potassium carbonate can act as a base by forming potassium hydroxide.

3. What is the energy of a photon that has a frequency of 2.3 x 1014 Hz?
The energy of a photon that has a frequency of 2.3 x 10¹⁴ Hz is 1.524 × 10-¹⁹J
HOW TO CALCULATE ENERGY OF A PHOTON:
The energy of a photon can be calculated by using the formula as follows:E = hf
Where;
E = energy of photon (J)
h = Planck's constant (6.626 × 10-³⁴J)
f = frequency of photon (Hz)
According to this question, a photon has a frequency of frequency of 2.3 x 10¹⁴ Hz. The energy of the photon can be calculated as follows:E = 6.626 × 10-³⁴ × 2.3 × 10¹⁴
E = 15.24 × 10-³⁴+¹⁴
E = 15.24 × 10-²⁰J
E = 1.524 × 10-¹⁹J
Therefore, energy of a photon that has a frequency of 2.3 x 10¹⁴ Hz is 1.524 × 10-¹⁹JLearn more at: https://brainly.com/question/23180082?referrer=searchResults

Answer:
c. chlorine, with an outer electron shell filled with 7 of a possible 8 electrons
Explanation:
Hope this helps!
The structure in the option A has 7 electrons in the outer shell of its electronic configuration , is unstable and so is most likely to form bond with another atom.
What is electronic configuration ?Electrons are arranged in various shells around the nucleus , this arrangement is called electronic structure or configuration.
Each shell can occupy certain fixed number of electrons.
Beside Option A , all the other configurations show stable structures as the last shell has eight electrons and are stable according to the octet rule.
The structure in the option A has 7 electrons in the shell and so is most likely to form bond with another atom.

which alkyl halide reacts fastest with trimethylamine in sn2 reaction?
Structure V reacts fastest with trimethylamine in SN2 reaction. Owing to less steric crowding in the transition state and ease of cleavage of the R - I bond
The question is incomplete, the complete question is shown in the image attache to this answer.
SN2 reaction is a type of nucleophilic reaction in which the nucleophile attacks the substrate from the reverse side. This is a synchronous reaction because the leaving group departs as the entering group attacks simultaneously in a hypervalent transition state.
SN2 reaction is favored by structure V owing to less steric crowding in the transition state and the easy of cleavage of the R - I bond. Hence, structure V reacts fastest with trimethylamine in SN2 reaction.

What two things do astronomers need to know about a star in order to calculate its luminosity or absolute magnitude? A.color and size B.color and distance C.distance and brightness D.size and distance
(đ) is answer of question.
Explanation:
However, the brightness of a star depends on its composition and how far it is from the planet. Astronomers define star brightness in terms of apparent magnitude — how bright the star appears from Earth — and absolute magnitude — how bright the star appears at a standard distance of 32.6 light-years, or 10 parsecs.
MARK ME AS A BRAINLIST PLZ
Astronomers measures the luminosity of stars by determining the magnitude of brightness and distance from earth.Thus option C is correct.
What is luminosity?Luminosity of a star is the total amount of energy radiated by them to a distance. The luminosity vary from star to star based on the distance to them.
Luminosity is basically measured in terms of brightness as observed from the earth. Stars will make a group in certain shapes and certain number called constellation. The overall brightness can be then higher for each constellation.
Astronomers define the brightness of stars by the apparent distance from the earth whereas the absolute magnitude is defined is terms of standard distance of 32.6 light years. Hence, the option C based on distance and brightness is correct.

what is the trend for atomic radii across the periods and down the group?
Answer:
So, in general, atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant.
Explanation:
Moving from left to right across a period, the atomic radius decreases. The nucleus of the atom gains protons moving from left to right, increasing the positive charge of the nucleus and increasing the attractive force of the nucleus upon the electrons.

when is it appropriate to form double or triple bonds in a lewis structure?
It is appropriate to form double or triple bonds in a Lewis structure when four or six electrons are shared.
A Lewis structure is a representation of a molecule using dots to show the valence electrons in the molecule. This dots are shown around the symbols of the elements.
However, in instances where four or six electrons are shared between bonding atoms, a double or triple bond is used. A double bond means that four electrons are shared. A triple bond means that six electrons are shared.

When you rub an inflated balloon on your head and it makes your hair stand up, the force that makes the hair stand up is known as static electricity.
When the balloon is rubbed on the head, electrons from the hair atoms move into the balloon, thus making the balloon to be negatively charged and the hair positively charged due to loss of electrons.
Unlike charges attracts. Thus, when you try to pull the balloon away slowly, the positively charged hair and the negatively charged balloon will attract each other and this is usually what makes the hair stand up.
More on static electricity can be found here: https://brainly.com/question/24160155
Answer:

Explanation:
this is because there is an imbalance between negative and positive charges
when you keep on rubbing, a negative charge is created which is carried by electrons.
