Answers

Answer 1

Answer:

For 1: Ionic

For 2: Ions

For 3: Covalent

For 4: Single

For 5: Double

For 6: Polar

Explanation:

For 1:

An ionic compound is formed when the complete transfer of electrons takes place from one element usually, metals (forming cation) to another element usually, non-metals (forming anions).

Hence, an ionic bond forms when one atom gives up one or more electrons to another atom

For 2:

An ion is formed when an element loses or gains an electron. Two types of ions are formed which are cations and anions.

Hence, atoms or molecules with a net electric charge due to the loss or gain of one or more electrons are ions.

For 3:

A covalent bond is defined as the bond which is formed by the sharing of electrons between two atoms.

Hence, a covalent bond involves sharing electron pairs between atoms, also known as a molecular bond.

For 4:

A single bond is defined as the bond in which 1 bond is present between the two atoms or 1 pair of electrons (two electrons) are shared between the atoms.

Hence, when one pair of electrons is shared between two atoms, a single bond is formed.

For 5:

A double bond is defined as the bond in which 2 bonds are present between the two atoms or 2 pairs of electrons (four electrons) are shared between the atoms.

Hence, when two pairs of electrons are shared between two atoms, a double bond is formed

For 6:

A polar bond is defined as the bond where unequal sharing of electrons takes place. This creates a dipole within a molecule.

Hence, a polar bond is a type of chemical bond where a pair of electrons is unequally shared between two atoms.

Question: A chemical reaction absorbs energy when occurring. Is this reaction Exothermic or Endothermic? If the enthalpy of the reactants was 300kJ and the enthalpy of the products was 450kJ, list one possible value for the enthalpy value of the transition state (the activation energy).

Answers

Explanation:

a chemical reaction that absorbs energy is known to be endothermic since heat is being taken in by the reaction. The value of the transition state would be 150 because you have to subtract the product's enthalpy and the reactant's enthalpy to obtain it. A positive value for the transition state also corroborates that the reaction is endothermic.

Answer: There are many forms of table salt: coarse salt, refined salt, iodized salt. It is a crystalline solid, white to very pale pink or gray in color, obtained from seawater or salt deposits. Salt obtained from seawater has crystals that are smaller or larger than rock salt. In nature, table salt consists mainly of sodium chloride (NaCl), but also a few other minerals (trace minerals). Table salt obtained from rock salt may appear more gray because of traces of trace minerals. Table salt is necessary for the survival of all living organisms, including humans. Table salt is involved in regulating the body's water content (liquid balance).

sulfur and oxygen can react to form both sulfur dioxide and sulfur trioxide in sulfur dioxide there are 32.06 grams of sulfur and 32 grams of oxygen in sulfur dioxide there are 32.06 grams of sulfur are combined with 48 grams of oxygen

a. what is the ratio of the weights of oxygen that combine with 32.06 g of sulfur ?
b. How do these data illustrate the law of multiple proportions? ​

Answers

Answer:

Explanation:

In sulfur dioxide there are 32.06 grams of sulfur and 32 grams of oxygen .

In sulfur trioxide there are 32.06 grams of sulfur are combined with 48 grams of oxygen.

The ratio of oxygen which reacts with 32.06 gram of sulfur is 32: 48 .

This ratio is equal to 2 : 3.

This is in accordance with law of multiple proportion because , the ratio of mass of oxygen which reacts with constant mass of sulfur is integral ratio . Hence they are in accordance with law of multiple proportions.

Answer:

sulfur and oxygen can react to form both sulfur dioxide and sulfur trioxide in sulfur dioxide there are 32.06 grams of sulfur and 32 grams of oxygen in sulfur dioxide there are 32.06 grams of sulfur are combined with 48 grams of oxygen

a. what is the ratio of the weights of oxygen that combine with 32.06 g of sulfur?

b. How do these data illustrate the law of multiple proportions? ​

Explanation:

In sulfur dioxide ([tex]SO_2[/tex])

32.06 g of sulfur reacts with 32.0 g of oxygen.

In sulfur trioxide ([tex](SO_3)[/tex] 32.0 g of sulfur reacts with 48.0 g of oxygen.

So, both th ecom[pounds are made from sulfur and oxygen,

But the amount of oxygen reacts with fixed amount of sulfur that is 32.06 g and it is in proportions that is:

32.0 g : 48.0 g

=2:3.

Hence, the ratio of oxygen combines with sulfur is in the ratio of 2:3.

b.

This data illustrates the law of multiple proportions.

Because the oxygen which is combining with fixed amount of sulfur is in proportions.

In the chemical reaction between aqueous magnesium chloride and sodium metal, what chemical amount (mol) of magnesium metal can be precipitated (produced) with 12.6 mol of sodium metal?

Answers

Answer:

6.3moles

Explanation:

The balanced equation of the reaction described above between aqueous magnesium chloride and sodium metal is as follows:

MgCl2(aq) + 2Na(s) → 2NaCl(aq) + Mg(s)

From the above equation, 2 moles of sodium metal (Na) produces 1 mole of Magnesium metal (Mg)

Hence, 12.6 mol of Na will produce (12.6/2) mol of Mg.

12.6/2 = 6.3moles of Mg metal.

Select the correct answer. What is the hydronium (H3O+) concentration of a solution with a pH of 3.60?

Answers

Answer: The hydronium [tex](H_{3}O^{+})[/tex] concentration of a solution with a pH of 3.60 is 0.56 M.

Explanation:

pH of a substance is the negative logarithm of concentration of hydrogen ions present in it.

It's formula is; pH = - log [tex][H^{+}][/tex]

When pH of a solution is 3.60 then its hydronium or hydrogen ion concentration is calculated as follows.

[tex]pH = - log [H^{+}]\\3.6 = - log [H^{+}]\\concentration of H^{+} = antilog (-3.6)\\= 0.56[/tex]

Thus, we can conclude that the hydronium [tex](H_{3}O^{+})[/tex] concentration of a solution with a pH of 3.60 is 0.56 M.

How much energy is needed to heat enough water to make a cup of tea (250 ml), if the water is initially at 20.0°C and you want to increase the temperature to 85.0°C? (1.00 mL of water has a mass of 1.00 g.)

As the tea in the previous question steeps, it cools from 85.0°C to 75.0°C. How much energy is lost by the tea as it steeps?

Answers

Answer:

Heat Energy needed (Q) = 68250 J

Energy lost (Q') = 10500 J

Explanation:

Applying,

Q = cm(t₂-t₁)............. Equation 1

Where Q = heat  energy needed, c = specific heat capacity of water, m = mass of water, t₁ = initial temperature, t₂ = final temperature.

From the question,

Given: m = 250 g = 0.25 kg, t₁ = 20.0°C, t₂ = 85.0°C

Constant: c = 4200 J/kg°C

Substitute these values into equation 1

Q = 0.25(4200)(85-20)

Q = 68250 J.

Similarly, heat lost

Q' = cm(t₁-t₂)................. Equation 2

Where Q = heat lost

Given: t₁ = 85°C, t₂ = 75°C

Substitute into equation 2

Q' = 4200(0.25)(85-75)

Q' = 10500 J

Both are true.
Neither are true.

Answers

"You have the same number of moles of each." is the true statement.

The mass of Gold and Silver differ, so that first statement can't be true because the quantities are the same. Because a mole measures solely amounts, like a dozen does, you will have the same amount of moles if the quantities are the same.

Answers

Answer: The statement enthalpy of the reactants is greater than that of the products is true of a reaction with a negative enthalpy.

Explanation:

A chemical reaction where energy is being released is called an exothermic reaction.

In an exothermic reaction, the value of enthalpy of reaction is negative in nature.

Also, heat is being released which means the reactants has more energy than the products due to which the value of enthalpy is negative.  

Thus, we can conclude that the statement enthalpy of the reactants is greater than that of the products is true of a reaction with a negative enthalpy.

From the question given above, the following data were obtained:

Molarity of LiF = 2 M

Mole of LiF = 4 moles

Volume =?

Molarity of a solution is simply defined as the mole per unit litre of the solution. Mathematically, it is expressed as:

Molarity = mole / Volume

With the above formula, we can obtain the volume of the solution as shown below:

Molarity of LiF = 2 M

Mole of LiF = 4 moles

Volume =?

Molarity = mole / Volume

2 = 4 / volume

Cross multiply

2 × volume = 4

Divide both side by 2

Volume = 4/2

Volume = 2 L

Therefore, the volume of the solution is 2 L.
