The use of ethanol instead of acetic acid is not the wise choice.
Why use of ethanol instead of acetic acid is not the wise choice?When you are out of acetic acid and decide to use ethanol as the solvent in the transformation, it would not be a wise choice because acetic acid and ethanol are two totally different chemicals. Due to different in features, it can't act the same and the desirable results can't be observed.
So we can conclude that use of ethanol instead of acetic acid is not the wise choice.

7.13 g of NaF are dissolved in enough water to make 201 mL of solution. What is the molarity of this solution
Answer:
0.846MExplanation:
To find the molarity, we have an equation: moles ÷ liter.
To find the moles of NaF, take the gram ÷ molar mass of NaF
7.13/42.0 = 0.170 moles of NaF
201 ml ÷ 1000 = 0.201L
0.170 ÷ 0.201 = 0.846MConvert 18◦C to Kelvin.

How to tell if a reaction is double bond or single
Answer:
Single replacement is a reaction in which one element reacts with another compund to form another compound and another element.
planation:
If the reaction is double displacement then two molecules will be displaced and if it is single displacement reaction then only one element displaces.
What is displacement reaction?Displacement reactions are those reactions in which any element of the given reactant will be displaced by any another element.
If only one element from the reactant molecules will displace then it will be known as single displacement reaction. If two elements or atoms will be displaced from the reactant molecules then it will be known as double displacement reaction.
Hence if one element displaceed then called the single displacement reaction and if two elements displaces then called as the double displacement reaction.

A 120g block of pinewood has a volume of 300cm3. Would this block float on water? (HINT: Water has a density of 1g/cm3). a. No, because the block is denser than water.
Also here's a free meme
The density of a material represents the denseness of that material in a specific given area. If an object has a density less than water then it will float on water otherwise it will sink. Here the wood will float on water.
What is density?The density of a material denotes the measurement which compares the amount of matter an object has to its volume. An object with more matter in a certain volume has a high density. It is defined as the mass per unit volume.
The density is usually represented by symbol ρ or by the letter D. The formula used to calculate the density is:
Density = Mass / Volume
D = 100 / 300 = 0.33 g/cm³
Here the density of water is 1.0 g/cm³ which is greater than the density of pine wood. So the pine wood will float on water.

The fruit which has the greater mass is peach i.e. 150 grams.
What is mass?Mass is a quantity which is used to define that what amount of substance will occupy any space or present in the given object.
We have given,
Weight of apples = 85,000 mg
Weight of peach = 0.15 kg
To compare the quantity first we have to convert both of these units in the same unit, and we know that:
In 1 kilogram = 1000 grams
And in 1 grams = 1000 milligrams
So, we convert both the units into grams as:
85,000 mg = 85,000 / 1000 = 85 grams
0.15 kg = 150 grams
So, the mass of peach is high.
Hence, peach has the greater mass.

what mass of sulfurous acid is produced when 245g of sulfur dioxide is reacted with water?
H₂O + SO₃ = H₂SO₃
The mass of sulfurous acid produced when 245g of sulfur dioxide is reacted with water is 313.8 g
StoichiometryFrom the question, we are to determine the mass of sulfurous acid produced
First, we will write the balaced chemical equation for the reaction
H₂O + SO₂ → H₂SO₃
This means 1 mole of H₂O reacts with 1 mole of sulfur dioxide (SO₂) to produce 1 mole of sulfurous acid (H₂SO₃)
Now, we will determine the number of moles of sulfur dioxide present
Mass of sulfur dioxide present = 245 g
Molar mass of sulfur dioxide = 64.066 g/mol
Using the formula,
[tex]Number \ of \ moles = \frac{Mass}{Molar\ mass}[/tex]
Then,
Number of moles of SO₂ present = [tex]\frac{245}{64.066}[/tex]
Number of moles of SO₂ present = 3.824 moles
This is the number of moles of SO₂ present
From balanced chemical equation
1 mole of H₂O reacts with 1 mole of sulfur dioxide (SO₂) to produce 1 mole of sulfurous acid (H₂SO₃)
Then,
Water (H₂O) will react with the 3.824 moles of sulfur dioxide (SO₂) to produce 3.824 moles of sulfurous acid (H₂SO₃)
∴ The number of moles of sulfurous acid produced is 3.824 moles
Now, for the mass of sulfurous acid produced
Molar mass of sulfurous acid = 82.07 g/mole
Using the formula,
Mass = Number of moles × Molar mass
Mass of sulfurous acid produced = 3.824 × 82.07
Mass of sulfurous acid produced = 313.8 g
Hence, the mass of sulfurous acid produced is 313.8 g

e. 144g of co2(g) is produced.
Based in the equation of the reaction, oxygen gas, O2 is the limiting reactant and 2 moles of CO remain unreacted
What is the equation of reaction between CO and O2?The reaction of carbon(ii) oxide, CO and oxygen, O2 is a redox reaction which produces carbon (iv) oxide, CO2.
The equation of the reaction. is given below:
2 CO + O2 ----> 2 CO2From the equation of the reaction, 2 moles of CO are required to react with 1 mole of O2 to produce 2 moles of CO2
The moles of the reacting substances is calculated using the formula:
moles = mass/molar massMolar mass of CO = 28 g
Moles of CO = 112/28 = 4 moles
Molar mass of 02 = 32 g

Infer Xenon, a nonreactive gas used in strobe lights, is a poor conductor of heat and electricity. Would you expect xenon to be a metal, a nonmetal, or a
metalloid? Where would you expect it to be on the periodic table? Explain.
Mark the lime poor conducter of heat and electricity.
Hence it's non metalYes why no ,Xenon is already has its secured place in modern periodic table.
It belongs to group 18,the Helium family and inert gas group having atomic no Z=54Xenon is a non-reactive gas. It will not conduct and react normally. Thus it can be classified as a non-metal. Xenon is placed in the inert gas or noble gas group that is group 18.
What are noble gases?Noble gases are inert gases in the 18th group of periodic table. Noble gases have completely filled orbitals and thus they no need other electrons.
Atoms participate in reaction when they are not stable because of the insufficient valence electrons. Noble gases such as argon, krypton, neon, xenon etc. have 8 valence electrons and thus are not reactive.
Metals are highly conductive and they are placed in the left side of periodic table. In periodic table, from left to right the metallic nature decreases and the other elements are called non-metals. Most of the non-metals are gases and very few such as silicon is metalloid.
Non-metals are insulators or poorly conduct electricity. Hence, xenon is a non-metal placed in the 18th group of periodic table.
