Determine the mass of 2.86 mole Co(NH3)6Cl3

Answers

Answer:

765 g Co(NH₃)₆Cl₃

General Formulas and Concepts:

Reading the Periodic Table of Elements

Explanation:

Step 1: Define

2.86 mol Co(NH₃)₆Cl₃

Step 2: Define conversions

Molar Mass of Co - 58.93 g/mol

Molar Mass of N - 14.01 g/mol

Molar Mass of H - 1.01 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar Mass of Co(NH₃)₆Cl₃ - 58.93 + 6(14.01) + 18(1.01) + 3(35.45) = 267.52 g/mol

Step 3: Dimensional Analysis

[tex]2.86 \ mol \ Co(NH_3)_6Cl_3(\frac{267.52 \ g \ Co(NH_3)_6Cl_3}{1 \ mol \ Co(NH_3)_6Cl_3} )[/tex] = 765.107 g Co(NH₃)₆Cl₃

mol Co(NH₃)₆Cl₃ and mol Co(NH₃)₆Cl₃ cancel outWe are left with grams (mass)

Step 4: Simplify

We are given 3 sig figs. Follow sig fig rules.

765.107 g Co(NH₃)₆Cl₃ ≈ 765 g Co(NH₃)₆Cl₃

Fossils of sea creatures have been found near the top of Mount Everest (8848m above the sea level). How do you think they could have got there?

Answers

Explanation:

The fossils can be found on top of mount Everest due to regional uplift of the crust.

Mount Everest is located a along a convergent margin between two tectonic plate. Due to similarity in density between the two margins, when they collide, there is tectonic build up.

Sedimentary rock layers originally at sea levels are uplifted to those tower peaks as the plate continues to grind against each other.

Most sedimentary rocks contains fossils. As the grinding continues, the uplift and deformation continues.

What is the molar mass of 18.12 g of gas
exerting a pressure of 3.05 atm on the
walls of a 5.85 L container at 280 K?

Answers

Answer:

23.3 g/mol

Explanation:

The molar mass of 18.12 g of gas exerts a pressure of 3.05 atm on the walls of a 5.85 L container at 280 K is 23.3 g/mole.

What is the molar mass?

Molar mass is the concentration of a substance that is present in a specific liquid. It is also called the concentration of a substance.

The molar mass can be calculated by the formula of an ideal gas:

PV = nRT

P is the pressure

V is the volume

n is the number of moles

R is the constant of gas.

T is the temperature.

The given amounts are the molar mass of 18.12 g.

The pressure is 3.05 atm.

The volume is  5.85 L

The temperature is 280 K

Putting the value in the equation

n = PV/RT = (3.05) (5.85) / (0.0821) (280) = 0.777 moles of gas

Molar mass = 18.12 g/0.777 moles = 23.3 g/mole

Thus, the Molar mass is 23.3 g/mole.

What is Reactivity ?

Reactivity in chemistry is the impulse for which a chemical substance undergoes a chemical reaction, either by itself or with other materials.

According to the question -

An atom that that does not react with the other atoms belongs to those elements which are chemically unreactive or inert elements. The reason behind their inertness is their completely filled outermost shell which can accommodate a maximum of 8 electrons which is as shown by their electronic configuration -  1s²2s²2p⁶. Hence, they are highly stable and don't react with other elements. Ex - Helium, Argon, Neon etc.

Hence, Option D is the correct alternative.

Adaptation is a process where they are changing their nature to suit the environment.

We have seen that plants do adaptation according to the environment, as in the summer season their leaves are hanging down but in the rainy season they show blossoms and green leaves. So, according to the environment for the survival and reproduction they adapt their body.

What is oxygen ?

The chemical element with the atomic number 8 and symbol O is called oxygen. It belongs to the periodic table's chalcogen group, is a very reactive nonmetal, and an oxidizing agent that easily produces oxides with most elements as well as other compounds.

Dioxygen is the name given to the colorless, odorless, and tasteless gas that is oxygen at standard pressure and temperature.

Chemical elements are substances that only contain one kind of atom, such as oxygen. Since oxygen has an atomic number of 8 and the official chemical symbol O, an oxygen atom has eight protons in its nucleus. At room temperature, oxygen is a gas that has no flavor, color, or odor.

According to the IUPAC Standards:

First of all we have to identify the longest carbon chain which is an alkane group according to this question.As a result of 7 carbon linked with single bonds it will be named heptane.Now moving to the other parts:

[tex]-CH3[/tex] is termed as methyl

As the both the methyl group( [tex]-CH3[/tex]  ) is linked with the fourth carbon the numbering is 4 for methyl.So,the IUPAC name of this compound in the image is 4,4-dimethyl heptane.

what happens to the electronegatity when you go from top to bottom on the periodic table?

Answers

Answer:

It decreases

Explanation:

As you go down a group from top to bottom, the electronegativity decreases. Across a period, electronegativity increases from left to right.

Electronegativity is the tendency with which the atoms of the element attracts valence electrons in a chemical bond. The more electronegative an element is, the stronger its affinity for electrons. Electronegativity values less than 2 shows an element is a metal. Metals are generally electropositive.
