The given equation represents a chemical reaction occurring in plants. Does this chemical equation show Conservation of Mass?
Answer:
Conservation of mass occur when your chemical equation is balanced.
So let's see if it is balanced:
6CO₂ + 6H₂O ------> C₆H₁₂O₆ + O₂
You need to have the same quantity of atoms of each element on the product side and reactant side.
Reactant side: 6CO₂ + 6H₂O
Product side: C₆H₁₂O₆ + O₂
Can all alkyl halides react with water to give alcohols?
Not all acid-catalyzed conversions of alcohols to alkyl halides proceed through the formation of carbocations. Primary alcohols and methanol react to form alkyl halides under acidic conditions by an SN2 mechanism.
Not all acid-catalyzed conversions of alcohols to alkyl halides proceed through the formation of carbocations. Primary alcohols and methanol react to form alkyl halides under acidic conditions by an SN2 mechanism.
In these reactions the function of the acid is to produce a protonated alcohol. The halide ion then displaces a molecule of water (a good leaving group) from carbon; this produces an alkyl halide:
Again, acid is required. Although halide ions (particularly iodide and bromide ions) are strong nucleophiles, they are not strong enough to carry out substitution reactions with alcohols themselves. Direct displacement of the hydroxyl group does not occur because the leaving group would have to be a strongly basic hydroxide ion:
We can see now why the reactions of alcohols with hydrogen halides are acid-promoted.
Carbocation rearrangements are extremely common in organic chemistry reactions are are defined as the movement of a carbocation from an unstable state to a more stable state through the use of various structural reorganizational "shifts" within the molecule. Once the carbocation has shifted over to a different carbon, we can say that there is a structural isomer of the initial molecule. However, this phenomenon is not as simple as it sounds.

In which substance are the electrostatic forces between molecules the strongest?
(1 point)
O acetone
O propane
turpentine
glycerin
The Whole Electrical Bonding Investigation Plan Quick check
1) B. boiling point, surface tension, vapor pressure
2) A. glycerin
3) C. the temperature at which additional heat energy causes the substance to change from a liquid to a gas
4) D. Heat each substance in liquid form to its boiling point. Measure the temperature of each substance
5) A. A liquid boils when the vapor pressure equals the atmospheric pressure.
The substance with the strongest electrostatic force has been Glycerin.
The boiling point has been the temperature required for the conversion of the liquid phase to the gaseous phase. The boiling point has been dependent on the intermolecular forces between the molecule.
The molecule with the higher interactions have a higher boiling point, and the molecules with the weaker interaction forces have a lower boiling point.
Among the given compounds, Glycerin has been the compound with the highest boiling point, thus the interactions within the glycerin molecules have been the greatest.

how many atoms of carbon atoms are in the reactant
Answer:
8
Explanation:
There are 8 carbon atoms in the reactants' side, because you multiply the 2 in front of C4H10 and the 4 under the C atom, and that gives you 8. So, 8 carbon atoms.
does SO3 2- show delocalized bonding
Answer:
YES
Explanation:
SO3 2-DOES show delocalized bonding
delocalized bonding occurs when there is a resonance structure and the electronic bonds are a delocalised "cloud" around the species
The resonance effect of the sulfite sructures ithe folowing link:
https://www.chemistryscl.com/general/lewis-resonance-structure-of-SO32-/index.php
Ions can be made by single element or covalently bonded group of elements. The covalently bonded group of elements is called polyatomic ions or polyatomic atoms. Therefore SO₃²⁻ show delocalized bonding.
What is Ions?Any species that contain charge whether it is positive charge or negative charge is called ions. The example of polyatomic ions are sulfate, phosphate, nitrate etc.
Cation is the species that loose electron and attain positive charge while anion is a species which gain electron and attains negative charge so when anion and cation combine in fixed ration the the overall charge of the molecule is zero that is molecule is neutral, the charge over cation and anion is also called oxidation state.
SO₃²⁻ show delocalized bonding as there is a resonance structure and the electronic bonds are a delocalized "cloud" around the species
Therefore SO₃²⁻ show delocalized bonding.

What is the osmotic pressure of a solution made by dissolving 35.0 g of glucose, C6H12O6, in enough water to form 800.0 mL of solution at 11.0 ∘C ?
Answer:
Osmotic pressure, a colligative property can be determined from
π = iMRT
π = osmotic pressure in atm
i = van't Hoff factor = 1 for glucose, a non electrolyte
M = molarity = 30.0 g x 1 mol/180 g x 1/0.650 L = 0.2564 M
R = gas constant = 0.0821 Latm/Kmol

Explanation:
Karl likes to use cruise control when he drives on
the highway. After setting cruise control at 33.53
m/s (75 mph). At this speed, how long would it
take Karl to travel 8 kilometers?
VELOCITY = DISTANCE/TIME
OR
V=D/T
SO
VT=D
SO
T=D/V
THE DISTANCE IS 8 KM
THE VELOCITY IS 75 MPH
THERE ARE 1.61 KM PER MILE
SO

What is the story dentist?This is a terrifying tale involving a man who is going to the dentist. He is dreadfully afraid of visiting the dentist because of the pain it would cause. Then, for him, things significantly worsen..
He notes that because he didn't know Curt Lemon well, mourning for him was challenging, but to avoid sounding sappy, he shares a quick Curt Lemon story.
The men are working in an operational region near the South China Sea in February. An Army dentist is flown in one day to examine the men's teeth. Curt Lemon is anxious as the platoon waits to be checked one by one.
Finally, he acknowledges that when in high school, he had some negative dental experiences. He claims that nobody should interfere with his teeth, and when he is called, he will decline to enter.
However, when the dentist summons him a little while later, Lemon gets up and enters the tent.Thus option B is correct.
