Answer:

a. 2

b. 10

c. 6

d. 14

Explanation:

The maximum number of the electrons which can be filled in the s orbital are:- 2

The maximum number of the electrons which can be filled in the p orbital are:- 6

The maximum number of the electrons which can be filled in the d orbital are:- 10

The maximum number of the electrons which can be filled in the f orbital are:- 14

Thus,

For each compound below, identify any polar covalent bonds and indicate the direction of the dipole moment using the symbols 84

Lostsunrise [7]

Answer:

H+ ----- Br-

H+ ----- Cl-

O₋₋ -----2H++

CH3 ----- O- ------ H+

Explanation:

Dipole moment occurs when there is bonding between a very strong electronegative element and hydrogen atom.

Electronegative elements are the element which attract electrons towards themselves, (that is they have strong affinity for electrons).

Generally, group 7 elements (Fluorine, Chlorine, Bromine, Iodine) of the periodic table are highly electronegative

What is the foundational principle of ALL science?

Natalija [7]

Answer:

Among the very basic principles that guide scientists, as well as many other scholars, are those expressed as respect for the integrity of knowledge, collegiality, honesty, objectivity, and openness.

Explanation:

Principles are ideas based on scientific rules and laws that are generally accepted by scientists. They are fundamental truths that are the foundation for other studies. ... They are more like guiding ideas that scientists use to make predictions and develop new laws.

Determine the quality of a two-phase liquid-vapor mixture of (a) H.O at 100°C with a specific volume of 0.8 m /kg. (b) Refrigera

Paul [167]

Answer:

a) 0.478 4

b) 1.45 × 10⁻⁶

Explanation:

A two phase liquid-vapor mixture

a) Given:

Temperature of H.O = 100°C

Specific volume of mixture, v = 0.8

now, we know

The specific volume of water at 100°C, vf = 0.001043 m³/kg

and,specific volume of steam At 100°C , vg = 1.671 m³/kg

also,

Specific volume, v = [ vf + x × (vg - vf ) ]

here, x is the quality

therefore, we get

0.8 = 0.001043 + [ x × (1.671 - 0.001043) ]

0.798957 = x × 1.669957

x = 0.478 4

b) Temperature of refrigerant = 0°C

Specific volume of refrigerant, v = 0.7721 cm³/g = 0.7721 × 10⁻³ m³/kg

Specific volume of fluid, vf = 7.72 × 10⁻⁴ m³/kg

Specific volume of gas, vg = 0.06930 m³/kg

Now,

Specific volume of two-phase mixture, v = [ vf + x × (vg - vf ) ]

on substituting the values in the above equation, we get

0.7721 × 10⁻³ = 7.72 × 10⁻⁴ + [ x × (0.06930 - 7.72 × 10⁻⁴ ) ]

x = 1.45 × 10⁻⁶

Identify whether each species functions as a Brønsted-Lowry acid or a Brønsted-Lowry base in this net ionic equation.CH3COO-+HCO

NARA [144]

Explanation :

According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.

Or we can say that, conjugate acid is proton donor and conjugate base is proton acceptor

The given equilibrium reaction is,

$CH_3COO^-+HCO_3^-\rightleftharpoons CH_3COOH+CO_3^{2-}$

In this reaction, $CH_3COO^-$ and $HCO_3^-$ are act as Bronsted Lowry base and acid respectively and $CH_3COOH$ and $CO_3^{2-}$ are act as Bronsted Lowry acid and base respectively.
