The atomic mass of Hydrogen : 1.02985

Isotopes are elements that have the same Atomic Number (Proton)  

Atomic mass is the average atomic mass of all its isotopes  

In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu  

An atomic mass unit = amu is a relative atomic mass of 1/12 the mass of an atom of carbon-12.  

Mass atom X = mass isotope 1 . % + mass isotope 2.% ..

99.985% is hydrogen-1 and 0.015% is hydrogen-2

The atomic mass of Hydrogen :

The clear liquid is less dense than the black liquid, which is why it floats on top. If the volume were different, you would visually see more clear liquid than black and vice versa.

The clear liquid is less dense than the black liquid

Answer:

A. The clear liquid is less dense than the black liquid

Explanation:

Since the clear liquid since on top of the black one it's density is less. Whatever liquid has a higher density will sink to the bottom of the flask.

In the definition of kinetic energy, it says: In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

The mass of the 2.34 × 10²³ atoms of copper is equal to 24.68 grams.

The Avogadro constant can be defined as the proportionality factor that the number of constituent particles in a sample with the amount of substance.

Avogadro’s number can be described as a dimensionless number that represents the number of entities in one mole of any substance. These elementary entities can be molecules, atoms, ions, electrons, or protons, etc.

Avogadro’s constant has a value approximately equal to 6.022 × 10²³ mol⁻¹.

Given, the number of atoms of copper = 2.34 × 10²³

The atomic mass of Cu Copper = 63.5 g/mol

So 6.022 × 10²³ atoms of Cu have mass = 63.5 g

Then 2.34 × 10²³  Cu atoms will have mass = [tex]\frac{63.5 \times 2.34 \times 10^{23}}{6.02 \times 10^{23}}[/tex] = 24.68 g

Therefore, 24.68 grams of Cu are there in 2.34 × 10²³ atoms of Cu.

Answer:

When two atoms join together they make compounds

Explanation:

A molecule is formed when two or more atoms join together chemically. If atoms combine that are of two or more different elements, we call that a compound. All compounds are molecules, but not all molecules are compounds.

Answer:

.

Explanation:

-Synthesis reactions are reactions that appear when two distinct atoms or molecules engage to structure a specific molecule or compound. Most of the time, when a synthesis response occurs, electricity is launched and the response is exothermic. However, an endothermic consequence is additionally possible.

-A decomposition response starts offevolved from a single substance and produces extra than one substance; that is, it decomposes. One substance as a reactant and greater than one substance as the merchandise is the key attribute of a decomposition reaction. For example, in the decomposition of sodium hydrogen carbonate (also recognized as sodium bicarbonate)

-A single-replacement response (sometimes referred to as a single-displacement reaction) is a chemical response in which one aspect is substituted for every other factor in a compound, producing a new aspect and a new compound as merchandise

-A double-replacement response (sometimes referred to as a double-displacement reaction) takes place when components of two ionic compounds are exchanged, making two new compounds. A attribute of a double-replacement equation is that there are two compounds as reactants and two distinctive compounds as product

-A combustion response happens when a reactant combines with oxygen, many instances from the atmosphere, to produce oxides of all different factors as products; any nitrogen in the reactant is transformed to elemental nitrogen, N2. Many reactants, referred to as fuels, incorporate normally carbon and hydrogen atoms, reacting with oxygen to produce CO2 and H2O

A chemical reaction may involve one or more reactants to yiled one or more products.

Below we are going to discuss the types of reaction under the following headings;

Synthesis reaction - This is a reaction in which two or more substances come together to yiled a single product.

Decomposition reaction - This involves the breakdown of a substance into new substances.

Single Replacement Reaction- This is a type of reaction in which an atoms replaces another in a compound.

Double Replacement Reaction - This is a reaction in which cations exchange anion partners in a reaction

Combustion - This is a reaction in which a substance is burnt in oxygen.

Answer:

This is true

Explanation:

Answer:

.

Explanation:

An element's location in the periodic table is largely depending on its electrons. The number of valence shell electrons determines its group, and the type of orbital in which the valence electrons lie in determines the element's block. Sometimes during these groups there are more like the alkali metals the non metals and gases :)

Answer:

Water can hold a lot of heat inside it and as the climate starts getting cold, the water releases the heat which heats up the climate

Due to the fact that water has a high heat capacity, its temperature has a very limited range, which causes the coastal areas close to having a similar small daily and seasonal temperature range.

"When the temperature of a material rises 1 K (or 1 °C), the amount of heat (J) absorbed per unit mass (kg)".

When the weather begins to grow chilly, water releases the heat it has stored inside, warming the environment.

High specific heat of the water makes it temperature resistant, and it helps the earth to maintain its temperature and helps organisms to maintain their functions at a constant temperature of the earth.

Thus, the normal temperature is necessary for maintaining the temperature of the earth and the water bodies maintain the temperature of the earth.
