Answer:

s orbital

Explanation:

The elements of Group 1 (IA) and Group 2 (IIA) have one and two electrons in their outermost shells respectively.

For the elements in group Group 1 (IA), the general outer electron configuration is ns1. This last electron is accommodated within an s orbital.

For the elements in Group 2 (IIA), the two outermost electrons are accommodated in an ns orbital, hence the answer.

Answer:

30 grams

Explanation:

Molarity of a solution represents its molar concentration, and can be calculated by using the formula as follows:

Molarity (M) = number of moles (n) ÷ volume (V)

Based on the information provided, volume of solution = 500 milliliters, molarity = 1M

Volume of solution in liters = 500mL ÷ 1000 = 0.50L

Molarity = n/V

1 = n/0.50

n = 0.50moles

Using mole = mass/molar mass

Molar mass of CH3COOH (acetic acid) = 60g/mol

Mass = mole × molar mass

mass = 0.50 × 60

mass = 30 grams.

A . 6.3 In a healthy pond, the temperature is 16°C (61°F). What is the most likely pH of this pond

In a healthy pond, the temperature is 16°C (61°F). 6.3 is the most likely pH of this pond.

A measure of the acidity or basicity of a substance or solution. The pH scale ranges from 0 to 14. A pH value of 7 is neutral on this scale, indicating that it is neither acidic nor basic.

A pH value less than 7 indicates that it is more acidic, while a pH value greater than 7 indicates that it is more basic.

"Potential of Hydrogen" is the full form of pH. The negative logarithm of H+ ion concentration is known as pH. As a result, the meaning of the name pH is explained as hydrogen strength or power.

Thus, In a healthy pond, the temperature is 16°C (61°F). 6.3 is the most likely pH of this pond, so the pond is more acidic in nature.

Explanation:

The noble gas configuration of vanadium (V), atomic number 23 will be [Ar] 3d34s2.

The electron configuration of noble gases would be known as that of the noble gas configuration. The propensity of chemical elements to gain stability forms the foundation of all chemical reactions. Chemical formation frequently leads to an entire electronic configuration approximating a noble gas for several main group elements.

The atomic number of V = 23

The noble gas configuration = [Ar] [tex]3d^{3} 4s^{2}[/tex].

Answer:

n physical sciences, subatomic particles are smaller than atoms. They can be composite particles, such as the neutron and proton; or elementary particles, which according to the standard model are not made of other particles. Particle physics and nuclear physics study these particles and how they interact.

Explanation:

a particle smaller than an atom (e.g., a neutron) or a cluster of such particles (e.g., an alpha particle).

“Many of the objections are long standing but apparently unknown to many geophysicists, while some are peculiar to the new global tectonics. The conclusions drawn, in order of probability, are (1) the continents have almost certainly not moved with respect to each other; (2) convection is not active throughout the whole mantle; (3) even if convection is active in the upper mantle it cannot account for drift; (4) pole positions derived from paleomagnetism, and results of this method of investigation in its global form generally, are afflicted with an unknown cause of error and are in any case too inexact for drift reconstructions.”

The molecular formula for Nickel (IV) Chloride will be NiCl₂. Nickel reacts with chloride to form a salt. The salt is yellow in color and anhydrous.

A molecular formula is a way of presentation of chemical formula of a compound. It gives the information related to the type of atoms, number of atoms which constitutes the compound and the chemical properties.

Molecular formula of a chemical compound can be derived by the valency of element. In this question, molecular formula of the compound can be derived by:

Valency of Nickel = 2

Valency of Chlorine = 1

By the cross-multiplication of valency:

element 1(valency of element 2). element 2 (valency of element 1)

= Ni (1). Cl(2)

= NiCl₂

Therefore, the molecular formula of Nickel (IV) chloride will be NiCl₂.

b. H₂O₂ = 34 g/mol

c. KCl = 74.55 g/mol

d. NaH₂PO₄  = 119.97 g/mol

Explanation:

In order to determine the molar mass of each compound we need to sum, the molar mass of each element.

a. Ca(OH)₂

40.08 g/mol (Ca) + 2 . 16 g/mol (O) + 2 . 1 g/mol (H) = 74.08 g/mol

b. H₂O₂ → 2 . 1 g/mol (H) + 2 . 16 g/mol (O) = 34 g/mol

c. KCl → 39.1 g/mol (K) + 35.45 g/mol (Cl) = 74.55 g/mol

d. NaH₂PO₄
