You can use lemon or lime juice as a 1 to 1 replacement for vinegar in egg dye recipes.
For example, if the recipe calls for 1 teaspoon (4.9 mL) of vinegar, use 1 teaspoon (4.9 mL) of lemon or lime juice.
You can use fresh or bottled lemon or lime juice. Both will work the same way.

From the addition of water to the molecule of an alkene is obtained a product containing 21.6% O2. Write the addition reaction. CH3-CH
Addition reaction between water molecules and alkene molecules produces alcohol.
What is addition reaction?Addition reaction generally takes place across the unsaturated carbon compounds.
When water molecule (H₂O) is added to the alkene which may be ethene (C₂H₄) molecule then formation of product i.e. ethanol (CH₃CH₂OH) takes place through the addition of hydrogen and hydroxyl group across the double bond. And reaction is shown in the attached image.
Hence formation of alcohol product takes place.

How many unique c13 nmr signals exist in the spectrum for the compound?.
Answer:
NMR (Nuclear magnetic resonance) is modern spectroscopy technique to study a variety of nuclei for e.g. 1H NMR, 2H NMR, 13C NMR, 15N NMR, 19F NMR etc
When any nuclei is place in any external magnetic field it starts spinning according to flamings right hand rule & the angular frequency of nuclei is called as Larmor Frequency (ω), and the charged nuclie generates oscillating electric field . There are two energy states Alpha state and Beta state depending on the alignment of spinning nuclie.
If radiowave of frequency (ω) is supplied to the operation the two electric field couples and energy gets absorbed by the nucleus this process is known Resonance.
Depending on the environment of all protons, not all protons absorbs the same amount of energy and the protons are shielded by electrons from the external magnetic field.
Tetramethylsilane (TMS) is used for 1H and 13C NMR, have the delta shift value of 0 PPM
[tex] \sf \: \delta \: shift = \frac{shift \: from \: TMS \: in \: Hz}{spectrometer \: frequency \: in\: MHz} [/tex]
The number of signals of any compound depends on the chemical shift, at every specific shift NMR shows a signal.
Let's understand step by step:
Consider the simplest organic molecule in Organic chemistry methane, methane have only one carbon atom hence it shows only One 13C NMR signal.
Let's move to ethane, ethane have two carbon atoms but the environment of both carbon atom are same that they are terminal carbon bounded to 3 H atoms each. since the chemical environment of both the Carbon atom is same it will again show only One 13C NMR signal.
Now coming to propane, propane have three carbon atoms, two on terminal (methyl groups) and one that is in middle touching both the carbon atoms, the Chemical environment of terminal two carbons are same so they both together will show one peak and the middle carbon(-CH2 group) have different environment so it will show the signal at different shift. Hence the total number of 13C NMR signal would be two!

Which of the following correctly represents the radioactive decay of cesium-137?
A sample of methane gas that has a volume of 3.8 L at 5°C is heated to 86°C at constant pressure. Calculate its new volume.
According to the Charle's law as pressure is constant the new volume of gas is 4.907 L.
What is Charle's law?Charles law is an experimental gas law which provides description about the behavior of gases which tend to expand on heating.It states that, at constant pressure, the temperature is in direct proportion with the volume that is,V∝T or V₁/T₁=V₂/T₂.The relation between volume and temperature is linear as the temperature increases volume also increases.
The graph of volume versus temperature is a straight line passing through the origin.The law was proposed by Jacques Charles , a french physicist in 1780.
In the given problem , on substituting values in above formula, V₂=3.8×278/359=4.907 L.
Thus , the new volume of methane gas is 4.907 L.

The sample of gas particles as the temperature decreases particles move slower, and their average kinetic energy decreases. option C is correct.
What are gas particles?
Every matter in this universe consist of small particles and gas also have small particles which are spherical in shape and collide with each other to move in zig zag form.
As temperature decreases the particles will move slow because of low energy as temperature is the source of energy for them and the collision between them also decreases due to which kinetic energy will also decreases.
On increasing the temperature the gas molecules move fast and kinetic energy will also be more.
Therefore, sample of gas particles as the temperature decreases particles move slower, and their average kinetic energy decreases. option C is correct.

Potassium carbonate (K2CO3) has one potassium atom bonded to carbon, and that carbon is also bonded to three oxygens. Their electronegativities are shown in the list:
K 0.82
C 2.55
O 3.44
How would you describe the bonds (K-C and C-O) in this molecule?
A: K-C is polar covalent, and C-O is nonpolar covalent.
B: K-C is ionic, and C-O is nonpolar covalent.
C: K-C is ionic, and C-O is polar covalent.
D: K-C is polar covalent, and C-O is polar covalent.
Answer:
I'm not all the way sure but I think it is C
Explanation:
The reason is because an ionic bond essentially donates an electron to the other atom participating in the bond. Also, the C-O I think is polar since it is evenly distributed.
Based on the electronegativity difference between them, K-C is ionic, and C-O is polar covalent.
What is a bond?A bond is formed by the interaction of two atoms. A bond can be either ionic or covalent.
Now we have to look at the electronegatives on each bond. The electronegativity difference between the K-C bond is larger than that between the C-O bond hence, K-C is ionic, and C-O is polar covalent.

When the heat moves from one place to another by the tendency of density, therma
energy is transferred by the process of
O convection
O radiation
O conduction
O evaporation
Answer:
The answer is A. Convection
Explanation:
Convection is single or multiphase fluid flow that occurs spontaneously due to the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity (see buoyancy). When the cause of the convection is unspecified, convection due to the effects of thermal expansion and buoyancy can be assumed. Convection may also take place in soft solids or mixtures where particles can flow.

Complete the word equation for the neutralisation reaction: sodium hydroxide + __________ → sodium chloride + water
Answer:
Hydrochloric Acid
Explanation:
NaOH + HCl = NaCl +H2O
In a Neutralization reaction a base (NaOH) and an acid (HCl) react together to form neutral products. H2O is always a product and a salt is also produced such as KCl or in this case NaCl.
The Na switches with the H to form NaCl.
and the 2 H and the O create H2O.
The neutralization reaction for this is Sodium Hydroxide + Hydrochloric acid → Sodium Chloride + Water.
What is Neutralization Reaction?Neutralization is a type of chemical reaction in which an acid and a base react with each other. In this reaction, neutralization results in the formation of any type of salt and water.
The proton ([tex]H^+[/tex]) from the acid combines with the hydroxide ([tex]OH^-[/tex]) from the base to make water [tex](H_2O)[/tex]. This type of reaction is known as neutralization reaction because it neutralizes the acid and base. If a strong acid and strong base react completely, then the resulting solution will have a pH of 7 (neutral).
For above given example,
Sodium Hydroxide is reacted with Hydrochloric acid to form Sodium Chloride and Water.
Thus, the neutralization reaction for this is Sodium Hydroxide + Hydrochloric acid → Sodium Chloride + Water.
