How many atoms are in a 58.2 L sample of Agent Orange gas?

Without looking at the periodic table, identify the group, period, and

kobusy [5.1K]

the group : 2

periode : 6

block = 2

atomic number = 56

<h3>Further explanation </h3>

We can divide the periodic system into several parts:

1. Block s: groups 1 and 2 (having a configuration of 1s-7s) consist of active metals except for H (non-metals) and He (noble gases)

2. Block p: group 13-18 (has a 2p-6p configuration), also called a representative element because it includes metals, non-metals and metalloids

3. Block d: group 3-12 (having the 3d-6d configuration), are transition metal elements

4. Block f: Lanthanides and Actinides (having a 4f-5f configuration), are inner transition elements that are also metal

The element with the electron configuration : [Xe]6s²

The outer shell 6s² :

Electron configuration :

1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s² : electron =56

group⇒valence electron ⇒2

period⇒the greatest value of the quantum number n⇒6

The element that is in period 6, and belongs to group 2 and has the atomic number 56 and in the block s

10.30 Indicate whether each of the following solutions is acidic,

goldfiish [28.3K]

Answer:

Basic

Explanation:

The pH scale is measured from 0 to 14.

At the pH scale of 7, a solution is neutral.

Any solution above 7 is basic.

Any solution below 7 is acidic.

Because you have been given the hydronium concentration [H₃O⁺], you can find the pH of the solution using the following formula:

pH = -log[H₃O⁺]

pH = -log(6.0 x 10⁻¹²)

pH = 11.22

As you can see, the solution must be basic because the pH lies within the basic range.

Explain the difference between the rate law for a reaction and the integrated rate law for a reaction. what relationship does ea

Sonja [21]

<span>While explaining the differences between the rate law and integrated rate law of the reaction, two statements apply from the options. They are 1. The rate law shows the relationship between the rate of a reaction and the concentrations of the reactants. This will give us an idea about the speed that reactants are turned to compounds and products. 2. The integrated rate law is a relationship between the concentration of a reactant and time. This gives an idea of amount of reactant left after a period of time.</span>

Enlist the 2factors which are used in the formation of dry ice

SVETLANKA909090 [29]

Carbon dioxide is a gas at normal room temperature and atmospheric pressure. Carbon dioxide gas converts into solid carbon dioxide when frozen to a particular temperature with no intermediate liquid phase. This frozen or solidified carbon dioxide is called dry ice. Dry ice is formed when gaseous carbon dioxide is cooled to very low temperatures under high pressure. High pressure brings about condensation of the gas molecules and low temperature solidifies the carbon dioxide gas. Therefore, tow factors that help in formation of dry ice are low temperature and high pressure.
