A student throws a 0.46kg bowling ball at a velocity of 25m/s what is the kinetic energy of the bowling ball in Joules

Answers

Answer:

The answer is 143.57 J

Explanation:

The kinetic energy of an object can be found by using the formula

[tex]KE = \frac{1}{2} m {v}^{2} \\ [/tex]

where

m is the mass

v is the velocity

From the question we have

[tex]KE = \frac{1}{2} \times 0.46 \times {25}^{2} \\ = 0.23 \times 625[/tex]

We have the final answer as

143.75 J

Fluorine (F) has seven electrons in its outermost shell. Fluorine _____.
-is a metal
-fills its shell by giving up seven electrons
-fills its shell by gaining one electron
-becomes a positively charged ion
-becomes a negatively charged ion
-is a nonmetal

Answers

Answer:

Fluorine is a non-metal, fills its shell by gaining one electron and becomes a negatively charged ion.

Explanation:

Fluorine have seven electrons in its outermost shell. This means that fluorine is located in Group 17(Halogens) in the Periodic Table. Note that halogens are non-metal elements. So fluorine is a non-metal.

Fluorine fills its shell by gaining one electron because it only needs one electron to achieve stable octet electron arrangement. ( it's easier to gain one electron than to lose all seven electrons in the outermost shell)

As fluorine atom gain one electron to achieve stable octet electron arrangement, its number of electrons becomes greater than its number of protons. So it becomes a negatively charged ion.

Select the term that matches each definition:
a) A decrease in the solubility of an ionic compound as a result of the addition of a common ion.
b) The mass of a salt in grams that will dissolve in 100 mL of water.
c) A solution that has dissolved the maximum amount of a compound at a given temperature. Any further addition of salt will remain undissolved.
d) The product of the molarities of the dissolved ions, raised to a power equal to the ion's coefficient in the balanced chemical equation.
e) The maximum number of moles of a salt that will dissolve in 1 L of solution.
*** Answer options for all questions: ***
- Solubility
- Molar Solubility
- Solubility product constant
- Common ion effect
- Saturated Solution

Answers

Answer: a) A decrease in the solubility of an ionic compound as a result of the addition of a common ion : Common ion effect

b) The mass of a salt in grams that will dissolve in 100 mL of water: Solubility

c) A solution that has dissolved the maximum amount of a compound at a given temperature. Any further addition of salt will remain undissolved: Saturated solution

d) The product of the molarities of the dissolved ions, raised to a power equal to the ion's coefficient in the balanced chemical equation : Solubility product constant

e) The maximum number of moles of a salt that will dissolve in 1 L of solution : Molar solubility

Explanation:

Solubility is expressed usually as the mass of solute per 100 grams or 100 ml of solvent.

Molar solubility of a solid is expressed as the concentration of the dissolved solid in a saturated solution.

Solubility product constant is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as [tex]K_{sp}[/tex]

The common-ion effect is the decrease in solubility of a sparingly soluble salt by the addition to the solution of a soluble compound with an ion in common with the precipitate.

Saturated solution is defined as the solution in which no more solute particles can be dissolved in the solvent.

Is a diamond a homogeneous or heterogeneous mixture?

Answers

Answer:

It's a heterogeneous mixture.

Explanation:

Diamond is made of just one element: carbon. Each carbon atom in diamond is connected to four other carbon atoms, in a crystal that extends on and on. There are other forms of pure carbon where the atoms are bonded differently, notably charcoal and graphite.

Answer:

It's a heterogeneous mixture.

Explanation:

Diamond is made of just one element: carbon.

The table below shows first ionization energies of some of the elements in the periodic table.Based on the information in the table, what can you conclude about the ability of noble gases to undergo ionization?

a
Noble gases give up first electrons easily compared to elements in other groups.
b
Noble gases cannot be forced to give up electrons.
c
The willingness of a noble gas to give up electrons decreases from top to bottom within the group.
d
It is more difficult to remove electrons from a noble gas than it is to remove electrons from elements in other groups.

Answers

Answer:

It is more difficult to remove electrons from a noble gas than it is to remove electrons from elements in other groups.

Explanation:

Let me restate here that in the noble gases, the outermost shell is filled. Owing to this full shell, noble gases has the outermost eight electrons required  for any specie to attain stability.

It is very difficult to remove an electron from a closed shell. This is why the first ionization energy of noble gases is usually far higher than that of elements from other groups.

Using the information in the table, calculate the number of moles in a 2.03 kg sample of citric acid
(C6H8O7)
Write your answer using three significant figures.
mol C6H8O7-

Answers

Answer:

Number of moles = 10.6 mol

Explanation:

Given data:

Molar mass of H = 1.008 g/mol

Molar mass of C = 12.01 g/mol

Molar mass of O = 16.00 g/mol

Mass of citric acid = 2.03 kg (2.03×1000 = 2030 g)

Number of moles of citric acid = ?

Solution:

Formula:

Number of moles = mass/molar mass

Now we will calculate the molar mass of citric acid:

C₆H₈O₇ = (12.01× 6) + (1.008×8) + (16.00×7)

C₆H₈O₇ = 72.06 + 8.064+112

C₆H₈O₇ = 192.124g/mol

Number of moles = 2030 g/ 192.124g/mol

Number of moles = 10.6 mol

The number of moles in a 2.03 kg sample of citric acid is :

- 10.6 mol

Molar Mass

Given:

Molar mass of H = 1.008 g/mol

Molar mass of C = 12.01 g/mol

Molar mass of O = 16.00 g/mol

Mass of citric acid = 2.03 kg (2.03×1000 = 2030 g)

Number of moles of citric acid = ?

Formula:

Number of moles = mass/molar mass

The molar mass of citric acid:

C₆H₈O₇ = (12.01× 6) + (1.008×8) + (16.00×7)

C₆H₈O₇ = 72.06 + 8.064+112

C₆H₈O₇ = 192.124g/mol

Number of moles = 2030 g/ 192.124g/mol

Number of moles = 10.6 mol

1. Consider the following: HCl (aq) + NaOH (aq) → NaCl (aq) + H2O (liq) ∆H = -57.62 kJ/mol
If a 25.0 mL of 0.144 M HCl (aq) at 25oC is added to 20.0 mL of 0.132 M NaOH (aq) at 25oC, calculate the final temperature of the contents. Assume the volumes are additive and that the resulting salt water solution has a density of 1.04 g/mL with a specific heat capacity of 3.93 J/goC. Note that you will also need to determine the limiting reactant.

Answers

Answer:

25.82°C

Explanation:

Based on the reaction, 1 mole of HCl and 1 mole of NaOH reacts, that means the reaction is 1:1. The moles of each compound are:

Moles HCl:

0.025L * (0.144mol/L) = 0.0036 moles HCl

Moles NaOH:

0.020L * (0.132mol/L) = 0.00264 moles NaOH

Thus, moles of reaction are 0.00264 moles

The heat released in a calorimeter is obtained using the equation:

Q = m*c*ΔT

Where Q is heat released in the reaction:

0.00264 moles * (-57.62kJ/mol) = 0.1521kJ = 152.1J of reaction

m is mass of the solution:

25.0mL + 20.0mL = 45mL * (1.04g/mL) = 46.8g

c is specific heat of the solution:

3.93J/gºC

And ΔT is change in temperature.

Solving for ΔT:

Q /mc = ΔT

151.2J / 46.8g*3.93J°C = 0.82°C = ΔT = Final temperature - Initial temperature.

Final temperature = 0.82°C + 25°C =

25.82°C
