In many cases, a negatively charged compound (ex Cl-) will interact with a positively charged metal (ex Fe2 ). Usually we would consider this type of interaction to be ionic, but in the case of metals we do not. What type of bond is being formed when a ligand interacts with a metal and how could you know that the bond you are forming is that type of bond

Answers

Answer:

See Explanation

Explanation:

An ionic bond occurs due to electrostatic attraction between a positively charged ion and a negatively charged ion.

A metal and a ligand are bound by a coordinate covalent bond or a dative bond. This bond occurs due to donation of electron pairs from ligands to available orbitals on metals.

The formation of coordinate bonds is evident when neutral molecules or negative ions with non bonding electrons donate same to empty metal orbitals. This is sometimes shown by an arrow pointing from the ligands to the metal center.

For instance; tetraammine copper II ion is formed when four ammonia molecules donate a lone pair each to available vacant orbitals of the copper metal center to form [Cu(NH3)4]^2+.

What is the phase label on HCl?


A. g

B. aq

C.

D. e

E. s

Answers

Answer:

B. aq if the reaction is inorganic (double or single displacement), neutralization, etc.

Explanation:

Hello there!

In this case, unfortunately we are not given the undergoing chemical reaction; however, in the most of the double displacement, neutralization, precipitation and in general, inorganic reactions, the hydrochloric acid must be B. aq as it must be dissolved in water as the reaction media. On the other hand, in some organic reactions, it can be either aqueous or gaseous, the latter, specially as a product. For that reason, you will need to make sure whether your reaction is organic or inorganic to correctly figure out the phase label.

Convert 2.178×1010 g to each of the following units.

Answers

Answer:

2.178x10⁷kg, 2.178x10¹³mg, 2.178x10¹⁶μg, 2.178x10⁴ metric tons.

Explanation:

The units are kg, μg, mg and metric tons (1metric ton = 1000kg)

To solve this question we must convert, first, the grams to milligrams, and to kilograms. Then, the kilograms to metric tons and the milligrams to micrograms:

kg:

2.178x10¹⁰g * (1kg / 1000g) = 2.178x10⁷kg

mg:

2.178x10¹⁰g * (1000mg / 1g) = 2.178x10¹³mg

μg:

2.178x10¹³mg * (1000μg / 1mg) = 2.178x10¹⁶μg

metric tons:

2.178x10⁷kg * (1metric ton / 1000kg) = 2.178x10⁴ metric tons

Answers

Answer:

releases, increase

Explanation:

The total energy of products in an Exothermic reaction is less compare to

total energy of the reactants. As a result of these the enthalpy becomes negative, then there is release of heat to the surroundings, which increase the energy of the immediate surroundings inform of heat. Hence the system release energy while the surroundings energy increase.

A mixture of water and water vapor is present in a closed vessel at 20 degrees Celsius. the total pressure of the system is 755.0 mmHg. Partial pressure of water vapor at 20 degrees Celsius equals 17.5 mm Hg. What is the partial pressure of H2

Answers

Answer:

737.5 mmHg

Explanation:

Ptotal=PH2O+PH2

P is the pressure and since we have Ptotal and PH2O, we can solve for PH2

755=17.5+x

755-17.5=x

x=737.5

Predict the reactants of this chemical reaction. That is, fill in the left side of the chemical equation.

______ + Cacl2 → H2O

Answers

Answer: [tex]Ca(OH)_2+2HCl\rightarrow CaCl_2+2H_2O[/tex]

Explanation:

Neutralization is a chemical reaction where an acid reacts with a base to form salt and water.

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side.

The balanced chemical equation will be:

[tex]Ca(OH)_2+2HCl\rightarrow CaCl_2+2H_2O[/tex]

Thus the reactants are calcium hydroxide [tex](Ca(OH)_2[/tex] and hydrochloric acid [tex](HCl)[/tex]

To check the accuracy of a new method, a standard copper alloy containing 23.24% Cu was analyzed and calculated to contain 23.17%. calculate the relative error of the method in parts per thousand (ppt).

Answers

Answer:

3ppt is the relative error of the method

Explanation:

The relative error is a measurement used to determine the accuracy of your experiment, the equation to find the value in parts per thousand is:

Error = |True Value - Observed Value| / True Value * 1000

Where True value is 23.24%

And Observed value is 23.17%

Replacing:

Error = |23.24% - 23.17%| / 23.24% * 1000

Error =

3ppt is the relative error of the method

Difference of the enthalpy (of a system) minus the product of the entropy and absolute temperature
Solution in which no more solute can be dissolved in the solvent

Answers

Answer:

Enthalpy, Entropy, Spontaneity, Gibbs free energy, saturated solution

Explanation:

Enthalpy is defined as the heat released or the heat absorbed during the process at a constant pressure which is equal to the Enthalpy shift. Enthalpy is also called as heat content and it is the sum total of internal energy and the product of the volume and pressure of a system.

Entropy is defined as the measure of randomness of a system or the disorder of the system.

Spontaneity is defined as the condition of being spontaneous. It is the condition where a reaction takes place without any help from outside.

Gibbs free energy is defined as the energy that is used to quantify the maximum work done in a thermodynamic system at constant temperature and pressure. It is the also known as the Gibbs energy or function.

Saturated solution is defined as the solution where the maximum amount of the dissolved solute is present in the solvent. In case of a saturated solution, the extra solute does not dissolve. In order words, it is a solution where no more solute can dissolved in solvent.

The sum of the internal energy plus the product of the pressure and volume for a reaction represents Enthalpy , Entropy is the extent of randomness in a system, Spontaneity is that condition that a reaction takes place without outside help, Gibb's free energy is the difference of the enthalpy (of a system) minus the product of the entropy and absolute temperature and Saturated solution in which no more solute can be dissolved in the solvent.

Which properties will define chemical reaction?

Thermodynamically chemical reactions will be define by considering the properties like entropy, enthalpy, free energy, internal energy, temperature and many more.

Enthalpy of the reaction tells about the total amount of heat released or absorbed during a chemical reaction, and it is calculated as sum of the internal energy plus the product of the pressure and volume for a reaction.Entropy of any reaction tells about the randomness and uncertainty present within the molecule or atoms.Spontaneity of any chemical reaction tells about the ease of completion of that reaction. Gibb's free energy is the total energy involved in that reaction and represented as difference of the enthalpy (of a system) minus the product of the entropy and absolute temperature.Saturated solutions are those solutions in which all solute get completely dissolved, no solute will remain undissolved.

Hence correct answers are Enthalpy , Entropy ,Spontaneity, Gibb's free energy and Saturated solutions.

In this project, you will develop a model of a chemical reaction that either releases energy or absorbs energy. Whether a reaction releases or absorbs energy depends on the overall difference in the bond energies of the reactants and products. Your model should show the relationships between the parts of the system. These parts are the molecules and atoms that take part in the reaction. The model should also distinguish the reaction system from other systems.
