How can you use the periodic table to determine the charge of an ion?

Answer:

C)12.09 Ampere

Explanation:

V= IR

Where I= current of the system

R= resistance= 0.67 ohm

V= potential difference=8.1 volts

Substitute the values

8.1= I× 0.67

I= 8.1/0.67

=12.09 Ampere

Answer:

132.53 J/kg.°C

Explanation:

Applying,

Q = cm(t₂-t₁)................ Equation 1

Where Q = amount of heat, c = specific heat capacity of platinum metal, m = mass of platinum metal, t₁ = initial temperature, t₂ = Final temperature.

Make c the subeject of the equation

c = Q/m(t₂-t₁).............. Equation 2

From the question,

Given: Q = 5.7 J. m = 18.7 g = 0.0187 kg, t₁ = 21.2°C, t₂ = 23.5°C

Substitute these values into equation 2

c = 5.7/[0.0187×(23.5-21.2)]

c = 5.7/0.04301

c = 132.53 J/kg.°C

Answer:

P2 = 37.5 psi

Explanation:

P1 = 32.1 psi

T1 = 25°C + 273 = 298K

T2 = 75°C + 273 = 348K

P2 = ?

P1/T1 = P2/T2

or

P2 = (T2/T1)P1

= (348K/298K)(32.1 psi)

= 37.5 psi

Answer:

The concentration of the original KOH solution is 0.1212 M.

Explanation:

Dilution is the process to reduce the concentration of solute in solution. This is accomplished by adding more solvent to the same amount of solute. In other words, dilution is the procedure followed to prepare a less concentrated solution from a more concentrated one, and it simply consists of adding solvent to an existing solution.

As only solvent is being added, the consequence is that by not increasing the amount of solute, but if the amount of solvent, the concentration of the solute decreases.

The expression for the dilution calculation is:

Ci* Vi = Cf* Vf

where:

In this case:

Replacing:

Ci* 25 mL= 0.1 M* 30.3 mL

Solving:

[tex]Ci=\frac{0.1 M*30.3 mL}{25 mL}[/tex]

Ci=0.1212 M

The concentration of the original KOH solution is 0.1212 M.

Answer:

D. 17

Explanation:

Halogens (group 17) are most likely to form a -1 ion. This is because they want to complete their octet. A prime example of this is sodium chloride. Sodium chloride is an ionic compound. Sodium gives up its valence electron, therefore, recieving a +1  charge, and Chlorine takes it, giving it a -1 charge. Chlorine is also in group 17, halogens.

Answer:

Rubbing the match against a rough surface

The activation energy is provided by friction between surfaces

Explanation:

Activation energy is the energy required to start a chemical reaction. It is the minimum energy that must be supplied for a reaction to proceed.

When we strike a match against a rough surface, what we are trying to do is to supply the required activation energy in the form of friction in order to get the combustion reaction started.

Hence, the activation energy for the combustion of a match head is supplied by friction when the match head is struck against a rough surface.

Answer: Volume is 22,3 ml

Explanation:  I assume solubility is expressed to 100 ml water

You can use proportion :  179 g / 100 ml water =  40 gm/ V

Multiplying the proportion gives 179 g  · V = 100 ml · 40 g | : 179 g

V = 4000  ml / 179 = 22,3 ml

ooh sorry, but will this help you now:

Ocean dynamics define and describe the motion of water within the oceans. Ocean temperature and motion fields can be separated into three distinct layers: mixed (surface) layer, upper ocean (above the thermocline), and deep ocean. Ocean currents are measured in sverdrup (sv), where 1 sv is equivalent to a volume flow rate of 1,000,000 m (35,000,000 cu ft) per second.

Surface currents, which make up only 8% of all water in the ocean, are generally restricted to the upper 4…

A. The electronic configuration for the isotope we want is as follows:

[tex]1s^2 2s^2 2p^6 3s^2 3p^6[/tex].

B. The element belongs to period 3 and group 18.

C.The last electron's four quantum numbers are:

m_s = +1/2 or -1/2 (since the electron can spin up or spin down)

D. With fluorine, the element will develop an ionic connection.

The positioning of electrons within an atom, molecule, or other physical structure, such as a crystal, is referred to as electronic configuration. It is typically represented by an array of numbers, letters, or superscripts that denote the number of electrons in each atom or molecule's shell or subshell.

Let the first isotope's mass number be x, the second isotope's mass number be y, and the third isotope's mass number be z. Also, let the first isotope's neutron number be a, the second isotope's neutron number be b, and the third isotope's neutron number be c. Using the information provided, we can construct two equations:

126 = x + y + z (equation 1)

a+b+c=60 (equation 2)

Because all three isotopes contain the same amount of protons, we can infer that their electrical configurations are the same. As a result, all that remains is to determine the electrical structure of one of the isotopes.

We can use the fact that the total of the mass numbers is equal to the amount of protons plus the number of neutrons. Let m be the isotope's mass number and z be the number of protons (the atomic number). Then:

m = z + n, where n is the number of neutrons.

The electrical arrangement of an element can also be used to calculate the atomic number. Assume if the isotope we're seeking for is a periodic table element. The element's electrical configuration can be written as:

[tex]1s^2 2s^2 2p^6 3s^2 3p^6[/tex]

The configuration's last electron is in the (n+1)s or (n+1)p orbital. As a result, we may calculate the atomic number by counting the number of electrons in the arrangement. For example, the atomic number for the aforementioned electrical configuration is 18 (2 + 8 + 8).

Let's look for the electrical configuration of the isotope we're after. Because the element's electrical configuration is not specified, we can presume it is a noble gas. As an example, consider argon (Ar), which has the electrical configuration:

[tex]1s^2 2s^2 2p^6 3s^2 3p^6[/tex]

Because argon belongs to period 3 and group 18 (also known as group 8A), the isotope we seek belongs to period 3 and group 18. This is due to the fact that atoms in the same class have the same amount of valence electrons and chemical characteristics.

As a result, the electrical configuration of the isotope we seek is:

[tex]1s^2 2s^2 2p^6 3s^2 3p^6[/tex]

b) The element belongs to period 3 and group 18.

c) The last electron's four quantum numbers are:

Because the electron is in the 3p orbital, n = 3 l = 1.

Because there are three 3p orbitals, m_l = -1, 0, or 1.

m_s = +1/2 or -1/2 (since the electron can spin up or spin down)

d) With fluorine, the element will develop an ionic connection. Because the element belongs to group 18, it has 8 valence electrons, making it a stable noble gas configuration. It may gain one electron to make a 1- ion or lose eight electrons to form an 8+ ion to obtain this state. Fluorine has seven valence electrons and can gain one electron to produce.

Therefore, the electronic configuration for the isotope we want is as follows:

[tex]1s^2 2s^2 2p^6 3s^2 3p^6[/tex]
