A 108.9 g sample of water absorbs 114.6 calories of heat. The specific heat capacity of water is 1 cal/(g·°C). By how much did the temperature of this sample change, in degrees Celsius?

Answers

Answer:

The temperature of this sample changes by 1.052 degrees Celsius

Explanation:

As we know

[tex]Q = mc\Delta T[/tex]

Where m is the mass of the substance

c is the specific heat of the substance

and [tex]\Delta T[/tex] is the change in temperature

Substituting the given values in above equation, we get -

[tex]114.6 = 108.9 * 1 * \Delta T\\\Delta T = 1.052[/tex]degree Celsius

The temperature of this sample changes by 1.052 degrees Celsius

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

A 15.0 mL solution of Sr(OH)₂ is neutralized with 21.1 mL of 0.350 M HCl. What is the concentration of the original Sr(OH)₂ solution?

Answers

Answer:

0.246 M

Explanation:

The reaction that takes place is:

Sr(OH)₂ + 2HCl → SrCl₂ + 2H₂O

First we calculate how many HCl moles reacted, using the given volume and concentration:

0.350 M * 21.1 mL = 7.385 mmol HCl

Then we convert HCl moles into Sr(OH)₂ moles, using the stoichiometric coefficients of the balanced reaction:

7.385 mmol HCl * [tex]\frac{1mmolSr(OH)_2}{2mmolHCl}[/tex] = 3.692 mmol Sr(OH)₂

Finally we calculate the concentration of the original Sr(OH)₂ solution:

3.692 mmol Sr(OH)₂ / 15.0 mL = 0.246 M

e. A chemical equation showing either oxidation or reduction ___________

Answers

Answer: a. Cathode

b. Galvanic cell

c. Anode

d. Electrolytic cell

e. half reaction

Explanation:

Galvanic cell or Electrochemical cell is defined as a device which is used for the conversion of the chemical energy produced in a spontaneous redox reaction into the electrical energy.

Electrolytic cell is a device where electrical energy is used to drive a non spontaneous chemical reaction.

In the electrochemical cell, the oxidation occurs at an anode which is a negative electrode and the reduction occurs at the cathode which is a positive electrode.  Thus the electrons are produced at anode and travel towards cathode.

The balanced two-half reactions will be:

Oxidation half reaction : [tex]M\rightarrow M^{n+}+ne^-[/tex]

Reduction half reaction : [tex]N^{n+}+ne^-\rightarrow N[/tex]

Thus the overall reaction will be: [tex]M+N^{n+}\rghtarrow M^{n+}+N[/tex]

Sum of the internal energy plus the product of the pressure and volume for a reaction
The extent of randomness in a system
The condition that a reaction takes place without outside help
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.

If I have 7.0 x 10^24 formula units of magnesium chloride, how many grams of chlorine would I have?

Answers

Answer:

824 g

Explanation:

First we convert 7.0 x 10²⁴ formula units of magnesium chloride (MgCl₂) into moles, using Avogadro's number:

7.0 x 10²⁴ formula units ÷ 6.023x10²³ formula units/mol = 11.62 mol MgCl₂

There are two Cl moles per MgCl₂ moles, meaning that we have (2 * 11.62) 23.24 moles of Cl

Finally we convert 23.24 moles of chlorine into grams, using chlorine's molar mass:

23.24 mol * 35.45 g/mol = 824 g

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]
