Answer :
Sugar : Compound
Air : Homogeneous mixture
Hot tea : Homogeneous mixture
Salt water : Homogeneous mixture
Explanation :
Element : It is a pure substance which is composed of atoms of similar elements.
Compound : It is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.
Heterogeneous mixtures : It is a mixture that has non-uniform composition throughout the solution and the particle size or shapes are also different.
There is a physical boundary between the dispersed phase and dispersion medium.
Homogeneous mixtures : It is a mixture that has uniform composition throughout the solution and the particle size or shapes are not different.
There is no physical boundary between the dispersed phase and dispersion medium.
As per question,
Sugar : It is a compound that is made from atoms of different elements combined together in a fixed ratio by mass.
Air : It is a homogeneous mixture of the gaseous substances of nitrogen, oxygen, and smaller amounts of other substances.
Hot tea : It is a homogeneous mixture because its composition is the same throughout the solution.
Salt water : It is a homogeneous mixture because its composition is the same throughout the solution.
Sugar compound
Air Homogeneous mixture
Hot tea Homogeneous mixture
Salt water Homogeneous mixture
Element:
An element is a simplest type of a pure substance which is composed of only one type of matter. For examples; silver, gold platinum etc.
Pure substance:
A compound is a pure substance which is composed of two or more type of matter in definite proportion. For examples; water which is composed by Hydrogen and oxygen etc.
Mixture:
A mixture is made from two or more type of matter in any proportion. Mixture are generally two types:
1. Homogeneous mixture
This is also known as solution, in which the composition of the substances is uniform.
Lemon-flavored water is an example of homogeneous mixture because in this the composition of the substances is uniform.
2. Heterogeneous mixture
In this form of mixture the composition of substance are not uniform and the component of mixture also visible.
Stuffed mushrooms is an example of Heterogeneous mixture because in this form of mixture the composition of substance are not uniform and the component of mixture also visible.
The specie which is acting as a catalyst is; Ag+(aq).
Discussion:
The catalyst is a specie that exists in the same form at the beginning and end of the reaction.
The reaction's mechanism is as follows;
Evidently, although Ag+(aq) was converted to Ag²+(aq) in Step 1 of the reaction; the Ag²+(aq) is reverted back to Ag+(aq) in Step 2 of the reaction.

Answer:
Ag⁺ acts as the catalyst.
Explanation:
Hello,
In this case, each step is reorganized:
- Step 1:
- Step 2:
- Step 3:
In such a way, Ag⁺ is converted to Ag²⁺ in the first step, but then it is regenerated to simple Ag⁺, therefore, Ag⁺ acts as the catalyst.

The stability of an atom is affected by the balance between the electrons, protons, and neutrons in an atom.
A particle less than an atom is referred to as a subatomic particle. A subatomic particle can either be an elementary particle, which is not made of other particles, or a composite particle, which is composed of other particles, according to the Standard Model of particle physics.
Particles smaller than an atom are referred to as subatomic particles. The three primary subatomic particles present in an atom are protons, neutrons, and electrons.

The charge on the most stable ion of bromine is - 1.
A charged atom or molecule is known as an ion. It has a charge because the atom or molecule's number of protons and electrons is not equal. Depending on whether an atom has more electrons than protons or fewer electrons than protons, an atom might become positively or negatively charged.
An atom is referred to be an ION when it is drawn to another atom due to an imbalance in its electron and proton numbers. A negative ion, or ANION, is an atom that contains more electrons than protons. A positive ion is one that has more protons than electrons.
Either there are too many or not enough electrons in a charged atom. Atoms in DS1 are heated to extremely high energy and unstable state. Then, a cathoderay in the thruster chamber discharges electrons, which strike the. Some of the electrons in the atoms in the chamber are stripped or knocked away when the electrons strike them. Plasma is created when a mass of charged, overheated atoms with free electrons.
Therefore, the charge on the most stable ion of bromine is - 1

-1 or Br- hope this helps
Answer:
=16.49 L
Explanation:
Using the equation
P1= 0.6atm V1= 30L, T1= 25+273= 298K, P2= 1atm, V2=? T2= 273
P1V1/T1= P2V2/T2
0.6×30/298= 1×V2/273
V2=16.49L
