The given statement "The process of adding solid CoCl₂•6H₂O to 12 M HCl will result in a pink solution" is true as CoCl₃ is a pink-colored compound.

CoCl₂•6H₂O is an ionic compound composed of cobalt ions and chloride ions held together by an ionic bond.

When the compound is added to a 12 M HCl solution, the HCl molecules replace the water molecules surrounding the ionic bond, thus producing the ions CoCl₃ and HCl.

This reaction results in the formation of a pink-colored solution due to the presence of CoCl3, a pink-colored compound. Thus, adding solid CoCl₂•6H₂O to 12 M HCl will result in a pink solution.

There are 1.142 grams of C₃H₆ in the 652 mL of sample of the gas at STP.

Using ideal gas equation,

PV = nRT,  pressure is P, volume is V, number of moles in n, gas constant is R, the temperature is T. At STP, the pressure is 1 atm, the temperature is 273 K, and the molar volume is 22.4 L.

We can use the following steps to calculate the number of moles of C₃H₆ present in 652 mL of the gas at STP:

Convert the volume to liters:

652 mL = 0.652 L

Calculate the number of moles using the ideal gas law:

PV = nRT

(1 atm) (0.652 L) = n (0.0821 L·atm/mol·K) (273 K)

n = 0.0272 mol

Calculate the mass of C₃H₆ using its molar mass:

m = n × M

M(C₃H₆) = 42.08 g/mol

m = 0.0272 mol × 42.08 g/mol

m = 1.142 g

It is nearest to option D, hence the mass is 1.22 grams.

Answer:

How many moles of each element are in one mole of Be (OH)2? 1 mole of beryllium, 1 mole of oxygen, 2 moles of hydrogen 1 mole of beryllium, 2 moles of oxygen, 2 moles of hydrogen CORRECT ANSWER 2 moles of beryllium, 2 moles of oxygen, 2 moles of hydrogen

Explanation:

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 1 moles of beryllium,  2 moles of hydrogen and 2 moles of oxygen  are in one mole of Be(OH)\(_2\).

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

Mathematically, the formula for mole is given as

number of moles of element=given mass of element÷ molar mass of element

1 moles of beryllium, 2 moles of hydrogen and 2 moles of oxygen  are in one mole of Be(OH)\(_2\).

Therefore, 1 moles of beryllium,  2 moles of hydrogen and 2 moles of oxygen  are in one mole of Be(OH)\(_2\).

Explanation:

When you give them feedback it would be a review for other people to see.

Have a great day.

Explanation:

Elements bond to each other by either (loosing / gaining) or sharing electrons with each other .

When bond is formed by loosing or gaining electron between metals and nonmetals then that type of bond is called ionic bond or electrovalent bond. Examples :-Nacl, Kcl etc..

When bond is formed between two elements that are non metals and bond form in between is due to sharing of electrons equally is called covalent bond.ex- Ccl4 , Sicl4 etc.

When bond formed between elements are shared unequally between atoms of elements then it is called co-ordinate bond. Ex:- No2, HCl etc..

Some people think about Metallic bond it's pretty simple actually it takes between same metal lattice. Definition is as follows

A metallic bonding is defined as where electrons freely move around a metal lattice (the metal atoms close united) to form a bond between the entire metallic element.ex:-Na, Mg and all other S , d and f block elements .

Last but not the least , Take case of hydrogen bonding it takes Place between H and electronegative elements like ( o , F , Cl , N ) etc examples are Hf , HCl , h2O etc.

Answer:   Because planets do not have nuclear fusion, they do not produce their own light. Instead, they shine with light reflected from a star. When we see planets in the night sky, such as Venus, the so-called "Evening Star," we're seeing reflected sunlight.

Explanation:

The heat of fusion is the amount of heat energy needed to turn anything solid into a liquid. There is a formula, Q = mHf. Because matter doesn't affect temperature, the temperature is not a factor.

There is no increase in the kinetic energies of the particles, and hence no rise in temperature, because the energy required for phase shifts is employed to break bonds. Similarly, energy is required to evaporate a liquid to defeat the attraction forces between the liquid's particles.

The energy that is given during a change in the state of matter is used to alter the binding energies rather than boost the kinetic energy of the molecules. As a result, the temperature doesn't change.

Answer:

It won't work as well. You can try though, it won't hurt anything

the value of work done is -235.73 J. The negative sign indicates that the work done is against the external pressure.

The chemical reaction produces gas that pushes the piston upward against an external pressure of 1.5 atm so that the volume of the gas changes from 0.95 L to 2.5 L. The work (in joules) can be calculated as follows:

W = -PΔV

where,

W = work done

P = external pressure

ΔV = change in volume

We are given the following values:

P = 1.5 atm

ΔV = 2.5 L - 0.95 L = 1.55 L

Substituting the given values in the formula for work done,

W = -PΔV = -(1.5 atm) (1.55 L) = -2.325 atm L

Converting the units of pressure and volume to SI units,

W = -2.325 atm L × 101.3 J L⁻¹ atm⁻¹ × (1 m³ / 1000 L) = -235.73 J

Thus, the value of work done is -235.73 J. The negative sign indicates that the work done is against the external pressure.

An atom is said to be electrically neutral if it has an equal amount of protons and electrons. On the other hand, an atom is electrically charged if its protons and electrons are not distributed evenly.

Neutral atoms are defined as when an atom has an equal amount of protons and electrons, it also has an equal number of electric charges, both positive and negative. As a result, every element in the periodic table has a neutral atomic structure.

Normal atoms have an equal amount of positive and negative particles and a neutral charge. Accordingly, an atom with a neutral charge is one in which the atomic number is matched by the number of electrons.

Thus, an atom is said to be electrically neutral if it has an equal amount of protons and electrons. On the other hand, an atom is electrically charged if its protons and electrons are not distributed evenly.

The empirical and molecular formula for the compound is CClH₂ and C₂Cl₂H₄ respectively.

Empirical formula is defined as a chemical formula where the number of atoms in the molecule is replaced by the most basic ratio of the elements in the compound.

Molecular formula is defined as a chemical formula that specifies how many atoms of each element there are in total in each substance's molecules.

Without respect to actual quantities, the empirical formula, which is a notation representing the ratios of the different elements contained in a compound, can be determined as follows:

71.65% Cl = 71.65g ÷ 35.5 = 2.02mol

24.27% C = 24.27g ÷ 12 = 2.0223mol

4.07% H = 4.07g ÷ 1 = 4.07mol

The smallest mole value is

Cl = 2.02mol ÷ 2.02 = 1

C = 2.0223mol ÷ 2.02 = 1

H = 4.07mol ÷ 2.02 = 2

So the empirical formula is CClH₂

The molecular formula can be calculated as

[CClH₂]n = 98.96g/mole

(12 + 35.5 + 2)n = 98.96

49.5n = 98.96

n = 2

So, the molecular formula is C₂Cl₂H₄

Explanation:

mass =(density)(volume)

mass=(5.7g/cm^3 )(48 cm^3)

cancel out your cm^3 and your are left with grams

multiply (5.7g)(48)=273.6 g

The mass of an object with a density of 5.7 g/cm³ and a volume of 48 cm³ is 273.6 grams.

Density is defined as the degree to which a material is packed together.

It is also defined as a mass per unit volume of the substance.

Its SI unit is kilogram per cubic meter or  gram per meter.

Density can be expressed as

Density = mass / volume

Mass =  density x volume

As given, Density = 5.7 g/cm³

Relative and average atomic mass both describe properties of an element related to its different isotopes. Out of these two Relative atomic mas is more accurate. The average atomic mass is 303g.

Mass defines the quantity of a substance. It is measured in gram or kilogram. Average mass is the mass of atoms of an element that are isotopes. It can be calculated by multiplying mass of a isotope to natural abundance of that isotope.

Average atomic mass = (mass of first isotope× percent abundance of first isotope)+(mass of second isotope× percent abundance of second isotope)

Substituting the given values

Average atomic mass=( 302 ×  12.64 %)+(304 × 18.23 %) + (306 × 69.13% )
