1 mole of H₂O has more molecules than other compounds. The correct option is A.

A molecule is a collection of two or more atoms held together by attractive forces known as chemical bonds.

The International System of Units uses the mole as the unit of material quantity. How many elementary entities of a specific substance are present in an object or sample is determined by its quantity.

The tiniest component of any substance is capable of existing independently while maintaining its chemical and physical properties and is composed of one or more elements.

Out of these molecules, water has more molecules than  1 mole Al(OH)₃ and 1 mole NaCl. They don't have the same number of moles.

Therefore, the correct option is A. 1 mole H₂O.

A species acts as an oxidizing agent if it gains electrons in a half-reaction. Conversely, it could potentially act as a reducing agent if it loses electrons in a half-reaction.

Answer:

All of them

Explanation: A molecule can be all of them

Answer:

false

Explanation:

1. Atomic Radius:

  Atomic radius increases down a group and decreases across a period. Lithium (Li) has a larger atomic radius than beryllium (Be) due to Li's additional electron shell. Be has fewer shells, resulting in a smaller radius.

2. 2nd Ionization:

  Second ionization energy is the energy needed to remove a second electron. Potassium (K) has higher second ionization energy than calcium (Ca) due to K's electron configuration ([Ar] 4s¹), requiring breaking into a filled shell.

3. C-C Bond:

  Carbon-to-carbon bond energy differs based on bond type. Ethene (C₂H₄) has a stronger double bond, requiring more energy to break, while ethane (C₂H₆) has a weaker single bond.

4. Boiling Point:

  Boiling points relate to intermolecular forces. Chlorine (Cl₂) has lower boiling point due to weaker dispersion forces compared to bromine (Br₂), with stronger dispersion forces leading to higher boiling point.

If you are looking for the formula, then it is NaOCl

Explanation:

Answer:

solubility in presence of 0.16M Cu(IO₃⁻)₂ = 3.4 x 10⁻⁴M*

Explanation:

        Cu(IO₃⁻)₂ ⇄           Cu⁺²          +   2(IO₃⁻)        

C(i)    ----------                0.16M                 0M

ΔC    ----------                   +x                   +2x

C(f)    ----------      0.16 + x ≅ 0.16M*        2x

Ksp = [Cu⁺²][IO₃⁻]²

7.4 x 10⁻⁸M³ = 0.16M(2x)² = 0.64x²

x = solubility in presence of 0.16M Cu(IO₃⁻)₂ = SqrRt(7.4x10⁻⁸M³/0.64M²)

= 3.4 x 10⁻⁴M*

*Note: This is consistent with the common ion effect in that a reduction in solubility is expected. The normal solubility of Cu(IO₃⁻)₂ in pure water at 25°C is ~2.7 x 10⁻³M.

1 silver, 1 nitrogen and 3 oxygen

Subscripts show the number of atoms of each element in a compound

There is no subscript after Ag which shows there is only one silver atom. There is no subscript after N which shows there is only one nitrogen atom. However, there is a 3 in the subscript after O which shows there are 3 oxygen atoms

Answer:

9

Explanation:

Nitrogen-16

Atomic number of nitrogen= 7

electrons=7

protons=7

First organisms to convert solar energy to chemical energy were the organisms which are called as cyanobacteria.

Energy which is stored in the chemical bonds of chemical compounds is called chemical energy.Chemical energy is released during the occurrence of chemical reaction.Reactions wherein energy is given out in the form of heat is called exothermic reactions.

Chemical energy can be converted to other forms of energy like electrical energy during the process of electrolysis and to thermal energy as in the case of thermal engines.

It can also be converted to kinetic energy during explosions . It is stored in batteries, coal, biomass, food, vehicle air bags,etc.During digestion chemical energy is converted to mechanical and thermal energy.

Elements can be made of one atom, like He, or be elemental molecules, such as hydrogen (H2), oxygen (O2), chlorine (Cl2), ozone (O3), and sulfur (S8). Atoms are not drawn to scale. Some elements are monatomic, meaning they are made of a single (mon-) atom (-atomic) in their molecular form...

Answer:

melting

Explanation:

Answer:

When a solid is heated the particles gain energy and start to vibrate faster and faster. ... Further heating provides more energy until the particles start to break free of the structure. Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid.

Check the image above, sorry if my handwriting is poor :(

Answer:

In today's world, the periodic table is very valuable for both students and scientists since it allows them to forecast the sorts of chemical reactions in which a specific element is likely to engage. Rather than memorizing facts and figures for each element, students and scientists can learn a great deal by simply looking at the table. They can learn about an element's reactivity, whether it is likely to conduct electricity, whether it is hard or soft, and many other characteristics by simply looking at the table.

Groups are made up of elements that are in the same column as one another and have attributes that are comparable to one another. If we look at the first column (the alkali metals), for example, we see that they are all metals that have a 1+ charge in reactions, react quickly with water and combine easily with nonmetals.

Periods are made up of elements that are arranged in a row next to one another and have the same maximum unexcited electron energy level as one another.

The periodic table also has the advantage of providing all the information you need to balance chemical processes at a glance, which is a very valuable feature. The atomic number and, in most cases, the atomic weight of each element are included in the table. The group of an element indicates the characteristic charge of that element.
