Answer:
C₃H₆ + H₂O = C₃H₈O
Explanation:
Hydration reactions (reactions involving converting an alkene to alcohol) have only one product, so there will be no byproduct along with propanol.
Propene reacts with steam to produce propan-2-ol. The reaction is C₃H₆ +H₂O[tex]\rightarrow[/tex]C₃H₈O. It is an example of hydration reaction.
What are hydration reactions?Hydration reaction is defined as a chemical reaction wherein a substance combines with water. In organic chemistry, when an unsaturated substance reacts with water it is called as hydration reactions.
The reaction involves breaking of hydroxyl bond in water which is highly exothermic releasing large amount of energy. Direct addition of water to an alkene is too slow and hence the rate is catalyzed by Lewis acids or Bronsted acids.
Hydration reactions are extensively used for industrial production of butanol and isopropanol,etc.The addition of water along the double bond in alkenes takes place according to Markovnikov's rule.

Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another. This exchange results in a more stable, noble gas electronic configuration for both atoms involved. An ionic bond is based on attractive electrostatic forces between two ions of opposite charge.

and salt as he tried to get them down from the
kitchen cupboard. He now has a mixture of glass,
sugar and salt. Describe in detail how he could
separate the three substances. Sugar and salt are
both soluble in water, but only sugar is soluble in
ethanol (remember that ethanol is flammable and
should not be heated directly).
Answer:
He could separate the mixture through filtration and fractional crystallization. Ethanol can also be added in order to remove salt.

a. Maritime tropical
b. Maritime polar
c. Continental tropical
d. Continental polar
4. An air mass that is warm and moist.
a. Maritime tropical
b. Maritime polar
c. Continental tropical
d. Continental polar
Answer:
An air mass that is described as having warm and moist air is called maritime tropical. This occurs when heat and moisture are transferred to the overlying air from the warm waters of the ocean or seas. Maritime Tropical air mass comes from the warm waters of the tropics and the Gulf of Mexico. When warm air moves northward moist air is transported to the United States which causes the increase in precipitation. Maritime Tropical masses are often felt in the Southeast part of the United States.

200 mL of nitrogen gas at 24K is heated to 47K.
Answer:
See explanation
Explanation:
The question is incomplete. However, base on the given information, one likely question could be that, we calculate the the volume of the nitrogen gas after heating it.
So, we have that:
Initial Volume, V1 = 200mL
Initial Temperature, T1 = 24k
Final Temperature, T2 = 47k
To solve the final volume of the gas, we apply the following ideal gas law equation
V1 * T1 = V2 * T2
Substitute values for V1, T1 and T2
200mL * 24K = V2 * 47K
200mL * 24 = V2 * 47
4800mL = 47V2
Solve for V2
V2 = 4800/47
V2 = 102.13 mL ------- Approximated
Hence, the volume of nitrogen gas after heating is 102.13mL

Which of the following elements are already balanced in this equation? FeS₂ + Cl₂ → FeCl₃ + S₂ Cl₂
Fe and S are already balanced in this equation
Further explanationBalanced indicates that the number of elements in question has the same number of atoms both on the left side (the number on the reactants side) and on the right side (the number on the product side)
Even though one of the elements is said to be balanced, the chemical equation as a whole cannot be said to be balanced, because the chemical equation has several components of the constituent elements.
To balance chemical equations, a coefficient in front of the compound is usually added either in the reactants or products
Reaction
FeS₂ + Cl₂ → FeCl₃ + S₂Cl₂
From this equation, it can be shown that: the Fe and S elements are balanced because the numbers are equal both on the left and right, while the Cl elements are not yet balanced
Fe, left=1, right=1 ⇒ balanced
S, left=2, right=1 ⇒ balanced
Cl, left=2, right=5⇒ not balanced
For balanced equations:
2FeS₂ + 5Cl₂ → 2FeCl₃ + 2S₂Cl₂
Which set of coefficients would balance the following equation
Answer:
3Mg + 2AlCl3 --> 2Al + MgCl2

A) Mention any two properties of an ideal fuel. (b) What is meant by calorific value? (c) 2kg of a fuel produces 48,000 KJ of heat energy and complete combustion. Calculate the calorific value of the fuel.
Answer and explanation:
A) An ideal fuel must:
- easy to transport and storage.
- have a high calorific value.
B) The calorific value for a fuel is the amount of heat - measured in Joules- which is produced during the complete combustion of the fuel. It is expressed in Joules per Kg of fuel (J/kg).
C) From the data:
mass of fuel = 2 kg
heat produced = 48,000 KJ
We calculate the calorific value by dividing the heat produced by the mass of fuel, as follows:
calorific value = heat produced/mass of fuel = (48,000 KJ)/(2 kg)= 24,000 kJ/kg
Since 1 KJ= 1000 J, we can express the calorific value in J/kg as follows:
24,000 kJ/kg x 1000 J/1 kJ = 2.4 x 10⁷ J/kg
How does an atom of one element differ from the atom of another element?
-Are there other ways to change the identity of an atoms? Explain, please.
Explanation:
The atoms of one element differs from the atoms of other elements in terms of the number of protons they contain. This is often taken as the atomic number of such an atom.
The number of proton is the best indicator of the atom one is dealing with. Based on this number, elements are categorized into distinct columns and rows on the periodic table. The atomic number is the number of protons or positively charge particles in the atom.II.
It is possible to change the identity of an atom. This is only possible by altering the atomic number of the atom.
Only nuclear reactions have this capability.
When an atom undergoes nuclear reaction that involves change in number of protons, transmutation occurs and a new atom forms.
