Use the molecular formulas for Ethanol (C2H5OH), Oxygen (O2), Carbon Dioxide (CO2), Water (H2O), and the yield sign () to write a balanced chemical equation for the reaction:

Answers

Answer 1
Answer: C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O

Explanation:

To balance the equation we have to find a combination of coefficients for the species that make the number of each element on both sides of the equation equal.

C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O

Checking to ensure the reactant and product sides of the equation are equal.

Explanation:

Consider the formula of the compound, calcium chloride. Select all the statements that apply to this image.

a) A covalent compound is formed
b) Chlorine becomes a negative ion
c) The chemical formula is CaCl2
d) Calcium transfers electrons to the chlorine atoms
e) The subscript 2, is used to balance the charges


Answers

Answer: Its B,C,D, and E

Explanation:

The correct statements about the compound calcium chloride are Chlorine becomes a negative ion, The chemical formula is CaCl₂, Calcium transfers electrons to the chlorine atoms and The subscript 2 is used to balance the charge.

Hence, Option B, C, D and E are correct.

Calcium Chloride

Calcium chloride is a crystalline white substance which is soluble in water. It is the chloride salt of calcium. The chemical formula of calcium chloride is CaCl₂. In calcium chloride, Calcium atom has two valence electrons.

Now lets check all statements one by one

Option (A): Calcium chloride is a ionic compound. Here calcium transfers its valence electrons to both chlorine atoms.

So, statement A is incorrect.

Option (B): In calcium chloride each chlorine atom gains 1 electron and we get a negatively charged ion Cl⁻.  

So, statement B is correct.

Option (C): In Calcium chloride the valency of calcium is +2 and the valency of chlorine is -1.  So the chemical formula is CaCl₂.

So, statement C is correct.

Option (D): In calcium chloride calcium transfer its two valence electrons to both the chlorine atoms.

So, statement D is correct.

Option (E): In calcium chloride the subscript 2 is used to balance the charge. The subscript show the number of atoms in compound.  

So, statement E is correct.

Thus, from the above conclusions we can say that The correct statements about the compound calcium chloride are Chlorine becomes a negative ion, The chemical formula is CaCl₂, Calcium transfers electrons to the chlorine atoms and The subscript 2 is used to balance the charge.

Hence, Option B, C, D and E are correct.

Tin, sulfur, and gold are not a mixture because they are pure elements.

What are the mixture and pure substance?

Pure substances can be described as elements that cannot be broken down into simple substances because they have only one type of atom in the whole composition.

A pure substance can be described as composed of two or more elements that are chemically combined and have a set composition such kind of pure substance is known as a compound.

A mixture can be described as made up of two or more different substances which are just physically combined but not chemically. A mixture can be separated into its initial components.

The composition of a heterogeneous mixture is non-uniform throughout the mixture while the composition of a homogeneous mixture is always the same in the entire mixture.

Therefore, tin, sulfur, and gold are pure elements, not a mixture.

The burning of a 0.37 g potato chip causes the temperature of 58.18 g of water in a soda can calorimeter to increase from 21.5℃ to 28.1℃. Calculate the amount of heat absorbed by the water. The specific heat of water is 4.184 J/g⋅℃. Express this answer in both Joules and Nutritional Calories.

Answers

The amount of heat absorbed by the water is 1606.6 J (383.99 Calories )

We'll begin by calculating the change in the temperature of the water.

Initial temperature (T₁) = 21.5 °C

Final temperature (T₂) = 28.1 °C

Change in temperature (ΔT) =?

ΔT = T₂ – T₁

ΔT = 28.1 – 21.5

ΔT = 6.6 °C

Finally, we shall determine the heat absorbed by the water. This can be obtained as follow:

Mass of water (M) = 58.18 g

Change in temperature (ΔT) = 6.6 °C

Specific heat capacity of water (C) = 4.184 J/gºC

Heat absorbed (Q) =?

Q = MCΔT

Q = 58.18 × 4.184 × 6.6

Q = 1606.6 J

Divide by 4.184 to express in Calories

Q = 1606.6 / 4.184

Q = 383.99 Calories

Therefore, the amount of heat absorbed by the water is 1606.6 J (383.99 Calories )
