Answer:
1-chlorobutane
Explanation:
Given that :
-- The compound A is made to react with alcoholic KOH and produce compound B.
-- The compound B on Ozonolysis produces methanol as well as propanol
The compound A should be a haloalkanes as treatment of haloalkanes with the alcoholic KOH, it will give alkene.
[tex]$CH_3CH_2CH_2CH_2Cl+KOH( \text{alcohol}) \rightarrow CH_3CH_2CH=CH_2+KCl+H_2O$[/tex]
So, the compound B should be Butene
Now the ozonolysis of the compound B or butene will give methanol and propanal as shown :
[tex]$CH_3CH_2CH=CH_2 \rightarrow CH_2O+CH_3CH_2CHO$[/tex]
Therefore, the compound A is 1-chlorobutane.
Which type of bond is found in an alkane?
O A. Double only
B. Single and double
O C. Single only
O D. Single and triple
Considering the definition of alkanes, single bonds are found in an alkane.
Definition of AlkanesAlkanes are a class of hydrocarbons (compounds containing only carbon and hydrogen) that are made up of a variable number of carbon atoms joined together by single bonds. In turn, each carbon atom bonds to hydrogen atoms, which may eventually be replaced by other atoms or functional groups.
In other words, alkanes are open or closed chain molecules that are linked by simple bonds.
Alkanes are saturated hydrocarbons because the bonds between carbon atoms are simple and stable. And as mentioned, the hydrogen atoms bonded to each carbon atom can be replaced by other atoms, such as halogens (fluorine, bromine, chlorine) or various groups or “radicals”. In the latter case, the structure becomes more complex giving rise to branched alkanes.
SummaryIn summary, single bonds are found in an alkane.

The following equation is balanced properly: 6CO2 + 6H2O → C6H12O6 + O2
Directions: Each set of lettered choices below refers to the numbered statements immediately following it. Select the one lettered choice that best fits each statement. A choice may be used once, more than once, or not at all in each set. The following questions refer to the below molecules: (A) CO2 (B) H2O (C) CH4 (D) C2H4 (E) PH3 The molecule that has trigonal pyramidal geometry
Answer:
The given molecules are:
(A) CO2 (B) H2O (C) CH4 (D) C2H4 (E) PH3
Which one has trigonal pyramidal geometry?
Explanation:
According to VSEPR (valence shell electron pair repulsion) theory, a molecule with a central atom having hybridization sp3 and with one lone pair of electrons has trigonal pyramidal geometry.
Among the given molecules,
CO2 has central atom carbon with sp hybridization without lone pairs.
So, it is a linear molecule.
H2O, the central atom is oxygen with sp3 hybridization and oxygen has two lone pairs. So, its geometry is V-shape or bent.
CH4 has central atom carbon with sp3 hybridization and no pairs.
So, its geometry is tetrahedral.
C2H4 ethene has carbon atoms as the central atoms with sp2 hybridization and carbon has no lone pairs.
So, its geometry is trigonal planar.
Answer:
PH3 has central atom P with sp3 hybridization.
P has one lone pair on it.
Hence, the geometry of PH3 is trigonal pyramidal.
. A circuit is set up with two parallel resistors, each of a resistance of 250Ω. a. What is the total resistance for this circuit?
Answer:
125 ohms
Explanation:
since they're parallel we do
1/total resistance = (1/250 ohms) + (1/250 ohms)
then you get 2/250 ohms
then you flip it so it's equal to total resistance/1
250÷2= 125

When sunlight travels from the vacuum of space into Earth's atmosphere it slowed down slightly. Explain why and name the light principle involved.
It is thought that global dimming is probably due to the increased presence of aerosol particles in Earth's atmosphere, caused by pollution, dust, or volcanic eruptions. Aerosols and other particulates absorb solar energy and reflect sunlight back into space. ... Water droplets in clouds coalesce around the particles.

Jello has a density of 1.14 g/mL. A box of Jello makes 475 mL of Jello and has 13 g of sugar. Determine the % m/m of sugar in the Jello. (Hint: d=m/v)
Answer:
2.34 %
Explanation:
Since the density of the Jello, ρ = 1.14 g/mL and ρ = m/v where m = mass of jello and v = volume of jello = 475 mL.
So, m = ρv
substituting the values of the variables into the equation, we have
m = ρv
m = 1.14 g/mL × 475 mL = 541.5 g
Since we have 13 g of sugar in the jello, the total mass present is 13 g + 541.5 g = 554.5 g
So, the percentage by mass of sugar present % m/m = mass of sugar present/total mass × 100 %
= 13 g/554.5 g × 100 %
= 0.0234 × 100 %
= 2.34 %
So, the percentage by mass of sugar present % m/m = 2.34 %
A reaction requires 22.4 L of gas at STP . There are 25.0 L of gas at 101.5 kPa and 373 K.
Which statement is true?
Use the ideal gas law: PV = nRT where R = 8.31 L-kPa/mol-K
A. There is not enough gas for the reaction.
B. Given this information, there is no way to tell if there is enough gas for the reaction.
C. There is excess gas for the reaction.
D. There is enough gas for the reaction.
Answer:
STP is 101.325 kPa pressure and 273K temperature
Also, at STP, 1 mol of an ideal gas = 22.4 L
Since the question states that 22.4 L are needed at STP, we know that ONE MOLE is needed. Now, the question is, how many moles are actually present?
V = 25.0 L
P = 101.5 kPa
T = 373K
n = ?
R = 8.31 L-kPa/Kmol
Solving the ideal gas law for n (moles) and comparing that to 1 mole, we have...
n = PV/RT = (101.5)(25.0)/(8.31)(373)
n = 0.82 moles of gas. THIS IS NOT ENOUGH as it is less than the ONE mole required.

Vanillin, C8H8O3, the principal component of vanilla beans, is very similar to glucose, C6H12O6 a type of sugar. Brittany Spears has a life threatening allergy to vanillin. After one of her concerts she was found dead in her dressing room. A glass lined with a white powder was found smashed on the floor next to her. Police think the glass was lined with vanillin suggesting she was murdered. A 2.54 g sample of this powder underwent carbon-hydrogen analysis. It’s combustion was found to produce 5.875 g of CO2 (g) and 2.41 g of H2O(g) . Find the empirical formula of this compound and determine if Brittany may have been poisoned?
b) Is this evidence enough to conclude for certain that the identity of the powder on the glass is indeed vanillin? Why or why not?
Answer:
The empirical formula is: CH2
Th powder is not vainillin
Explanation:
We can find empirical formula of a compound CₐHₓOₙ knowing that moles CO2 = Moles C, 2 Moles H2O = Moles H and that we can find the mass of oxygen by the difference of masses of the atoms:
Moles C = Moles CO2 -Molar mass: 44.01g/mol-
5.875g * (1mol/44.01g) = 0.1335 moles C * (12.01g/mol) = 1.60gC
Moles H2O and moles H -Molar mass: 18.01g/mol-
2.41g H2O * (1mol / 18.01g) = 0.1339 moles H2O * (2mol H / 1mol H2O) =
0.2676 moles H * (1g/mol) = 0.27g H
The empirical formula of this compound is the ratio of C:H:
0.2676 moles H / 0.1335 moles C = 2
The empirical formula is:
CH2
In vainillin, the moles of Carbon = Moles of Hydrogen. the experiment shows the moles of hydrogen are twice the moles of carbon. Thus, the powder is not vainillin

How do catalysts increase reaction rates? *
By increasing the activation energy.
By broadening the energy barrier.
By forming an activated complex with lower energy.
By changing the net thermodynamics of the reaction.
Answer:
By forming an activated complex with lower energy.
Explanation:
When catalyst is added to a reaction , it forms an activated catalyst which has lower activation energy . So initiation of reaction requires less energy and reaction becomes fast .
Hence third option is correct.

In a solution containing 21.2 g sodium carbonate in 1.50 L of solution, calculate
the concentration of the sodium and carbonate ions.
Answer:
0.13 molL-1
Explanation:
We must first obtain the number of moles of sodium carbonate as follows;
Number of moles = mass/molar mass
Number of moles = 21.2 g/106 g/mol
Number of moles= 0.2 moles
Number of moles = concentration × volume
Volume = 1.50 L
Concentration = number of moles/volume
Concentration = 0.2 moles/1.5 L
Concentration = 0.13 molL-1

Question 12 of 15
Matter can undergo chemical reactions and nuclear reactions. Which
statement is true for both types of reactions?
A. The reactants are changed to form the products.
B. The reactants can be elements or compounds.
C. The products can be elements or compounds.
D. The products can be the same as the reactants.
Answer:
A. The reactants are changed to form the products.
Explanation:
Chemical reactions are reactions that involves a change in the chemical composition of substances involved while a nuclear reaction is the process of fusing together or splitting the nucleus of an atom. According to this question, matter is said to undergo both types of reaction.
However, one similarity in both chemical and nuclear reactions is that substances called REACTANTS are changed to form PRODUCTS. In nuclear reaction, the atoms joined or split are the reactants while the ones formed are the products.
Answer: A
