Which of the following has the smallest atomic radius?
a B
b Al
c F
d N
e Ga

Answers

Answer:

c. F

Explanation:

As you go top to bottom down a column of the periodic table, atomic radius increases.

As you go left to right across a period of the periodic table, atomic radius decreases.

Knowing this trend, that means that the smallest atomic radius would be located in the top right of the periodic table. The closest element to that point is fluorine, or answer C.

Neon is used in lighting advertising displays.

Which statement can be applied to an atom of neon?

A The atom has the same electron arrangement as Cl– ion.
B The atom has two more electrons than an atom of oxygen.
C The atom has the same number of outer electrons as an atom of helium.
D The atom has the same number of electrons as a Ca2+ ion.

Answers

Answer:

B. The atom has two more electrons than an atom of oxygen.

Explanation:

In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.

Oxygen has a total number of eight (8) electrons while neon has total number of ten (10) electrons. Therefore, an atom of oxygen is able to gain (receive) two (2) more electrons in order to have the same electron arrangements as the noble gas i.e an atom of neon with an atomic number of 10.

This ultimately implies that, an [tex] O^{2-} [/tex] atom contains the same number of electrons as an atom of neon.

Hence, a neon atom has two more electrons than an atom of oxygen.

Additionally, Neon is used in lighting advertising displays.

2 Hgo 2 Hg + O2

1. How many grams of mercury (Hg) can be

produced from 3.55 moles of Hgo?

Answers

Answer:

712 moles of Hg are produced

Explanation:

Based on the reaction:

2HgO → 2Hg + O₂

Where 2 moles of HgO reacts producing 2 moles of Hg and 1 mole of O₂

To solve this question we need to find the moles of Hg produced, then, using its molar mass:

Moles Hg:

3.55mol HgO * (2 mol Hg / 2 mol HgO) = 3.55 mol Hg

Grams -Molar mass Hg: 200.59g/mol-:

3.55mol Hg * (200.59g/mol) =

This is using unit conversions. There are 1000 millimeters in 1 meter, so you would divide your starting value, 117 millimeters by 1000 millimeters. The units will cancel because they are being divided by themselves and you are left with 0.117 meters.

What is the total amount of heat needed to change 2.25 kg of silver at 0.0°C to 200.0°C? The specific heat of silver is 0.129 J/g·°C (2.25 kg = 2250 g)

Answers

Answer:

Q = 5805 Joules.

Explanation:

Given the following data;

Mass = 2250g

Specific heat capacity of silver = 0.129 J/g·°C

Initial temperature, T1 = 0.0°C

Final temperature, T2 = 200.0°C

To find the quantity of heat needed;

Heat capacity is given by the formula;

[tex] Q = mcdt[/tex]

Where;

Q represents the heat capacity or quantity of heat. m represents the mass of an object. c represents the specific heat capacity of water. dt represents the change in temperature.

dt = T2 - T1

dt = 200 - 0

dt = 200°C

Substituting the values into the equation, we have;

[tex] Q = 225*0.129*200[/tex]

Q = 5805 Joules.

Therefore, the amount of heat needed is 5805 Joules.

The amount of heat needed will be "5805 Joules".

Given values:

Mass, [tex]m = 2250 \ g[/tex]Specific heat capacity, [tex]0.129 \ J/g.^{\circ} C[/tex]Initial temperature, [tex]T_1 = 0.0^{\circ} C[/tex]Final temperature, [tex]T_2 = 200.0^{\circ} C[/tex]then,Change in temperature, [tex]dt = T_2-T_1[/tex]

                                                      [tex]= 200-0[/tex]

                                                      [tex]= 200^{\circ} C[/tex]

As we know the formula,

Heat capacity, [tex]Q = mcdt[/tex]

By substituting the values, we get

                                [tex]= 225\times 0.129\times 200[/tex]

                                [tex]= 5805 \ Joule s[/tex]

Thus the above answer is right.

Answers

Answer:

A. 1:1

Explanation:

Lithium 1s2 2s1

Chlorine 1s2 2s2 2p6 3s2 3p5

Lithium is a group 1 element. When it forms a compound, it loses it's one valence (outermost) electron.

Chlorine is a group 7 element. When it forms a compound, it gains one electron to achieve a stable electronic configuration.

Since Li loses one electron and Cl gains one electron. The formular of the compound formed would be;

LiCl

The correct option is;

A. 1:1

In the above figure, what type of bond is formed?



metallic


ionic


covalent


nonpolar

Answers

The answer is Ionic bond

Answer:

It is an covalent bond.

Explanation: The bond is covalent because all the dots are equaled to each other therefore creating a stable bond. When the bonded atoms have a lower total energy than that of widely separated atoms, a covalent bond forms. The electrons are not moved from one atom to the other in polar covalent bonds, such as that between hydrogen and oxygen atoms, as they are in an ionic bond.
