Answer:

Explanation:

To understand how the answer is gotten, it is recommended to prepare the ionic equation for watch of the compounds and this can be gotten by considering the valency of the atoms.

LiCl;

Li belongs to group 1 so it has a valency of + 1

Cl belongs to group 7 so it has a valency of -1

Ionic equation is given as; Li+ + Cl- -> LiCl

The number of electrons that are transferred between the cation and anion to form the ionic bond is 1.

NaF;

Na belongs to group 1 so it has a valency of + 1

F belongs to group 7 so it has a valency of -1

Ionic equation is given as; Na+ + F-   ->  NaF

The number of electrons that are transferred between the cation and anion to form the ionic bond is 1.

CaO;

Ca belongs to group 1 so it has a valency of + 2

Cl belongs to group 6 so it has a valency of -2

Ionic equation is given as; Ca2+  + O2-  -> CaO

The number of electrons that are transferred between the cation and anion to form the ionic bond is 2.

BaS;

Ba belongs to group 2 so it has a valency of +2

S belongs to group 6 so it has a valency of -2

Ionic equation is given as; Ba2+ + S2-   ->  BaS

The number of electrons that are transferred between the cation and anion to form the ionic bond is 2.

NaBr;

Na belongs to group 1 so it has a valency of + 1

Br belongs to group 7 so it has a valency of -1

Ionic equation is given as; Na+ + Br- -> NaBr

The number of electrons that are transferred between the cation and anion to form the ionic bond is 1.

Nicotine is 74.1% carbon, 8.6% hydrogen, and 17.3% nitrogen by mass. What is its molecular formula if its molar mass is 162.26 g
WINSTONCH [101]

first we need to find the empirical formula of nicotine

empirical formula is the simplest ratio of whole numbers of elements making up a compound

the percentage compositions for each element has been given. So we can calculate for 100 g of the compound.

masses of elements and the number of moles

C - 74.1 g - 74.1 g/12 g/mol = 6.17 mol

H - 8.6 g - 8.6 g / 1 g/mol = 8.6 mol

N - 17.3 g - 17.3 g / 14 g/mol = 1.23

divide all by the least number of moles

C - 6.17 / 1.23 = 5.01

H - 8.6 / 1.23 = 6.99

N - 1.23 / 1.23 = 1.00

when the atoms are rounded off to the nearest whole numbers

C - 5

H - 7

N - 1

empirical formula is C₅H₇N

we have to find what the mass of 1 empirical unit is

mass - 5 x 12 g/mol + 7 x 1 g/mol + 14 g/mol = 81 g

molecular mass is 162.26 g/mol

we have to find how many empirical units make up 1 molecule

number of empirical units = molecular mass / mass of 1 empirical unit

= 162.26 g/mol / 81 g = 2.00

there are 2 empirical units

molecular formula is - 2 (C₅H₇N)

molecular formula - C₁₀H₁₄N₂

If we compare a mole of carbon atoms to a mole of oxygen atoms, which sample will contain more atoms?.
Alex Ar [27]

Since 1 mole of any element contains 6.0221023 atoms, a mole of carbon and a mole of oxygen will have the same number of atoms.

<h3>Is a mole of oxygen equivalent to a mole of carbon?</h3>

Answer and justification The molar mass of carbon differs from the molar mass of oxygen, hence this assertion is untrue. As a result, one mole of oxygen and one mole of carbon cannot have the same mass.

<h3>What kind of link unites carbon and oxygen?</h3>

A polar covalent link between carbon and oxygen is known as a carbon-oxygen bond. With six valence electrons, oxygen likes to either share two of them in a bond with carbon, leaving the remaining four unoccupied.

A pressure cooker contains 5.68 liters of air at a temperature of 394 K. If the absolute pressure of the air in the pressure coo
Arturiano [62]

Answer:

Explanation:

We shall find out volume of air at NTP or at 273 K and 10⁵ Pa ( 1 atm )

Let it be V₂

\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}

\frac{2\times 10^5\times 5.68}{394} =\frac{10^5\times V_2}{273}

V₂ = 7.87 litres

22.4 litres of any gas is equivalent to 1 mole

7.87 litres of air will be equivalent to

7.87 / 22.4 moles

= .35 moles .

Dmitrij [34]

Answer:the sodium carboxylate salt

Explanation:

The reaction between the carboxylic acid and the sodium hydroxide yields a sodium carboxylate. This sodium carboxylate is an ionic in nature; RCCOO-Na+. This can effectively interact with water and remain in the aqueous phase since it is composed of the carboxylate ion and sodium ion in solution. The aqueous phase always contains water soluble ionic substances of which the sodium carboxylate is a typical example of such.
