Answer: Yes- Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur. Rusting is an example of a chemical change. A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust.

Model A is better than Model B as Model A shows the three-dimensional shape of the molecule, but Model B does not. The correct option is c.

The smallest particle of a substance possesses all of its physical and chemical properties. One or more atoms make up a molecule.

Knowing the molecular weights of the molecules allows us to calculate their sizes. The molecular weight of a molecule is the sum of the atomic weights of the atoms in the molecule.

The relative atomic mass of particles determines their size. Particles with a higher relative atomic mass weigh more than particles with a lower relative atomic mass. Larger atoms have heavier iotas and a larger relative atomic mass.

Therefore, the correct option is c, Model A shows the three-dimensional shape of the molecule, but Model B does not.

Answer:

A hydrogen bond is an intermolecular force (IMF) that forms a special type of dipole-dipole attraction when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons. Intermolecular forces (IMFs) occur between molecules. Other examples include ordinary dipole-dipole interactions and dispersion forces. Hydrogen bonds are are generally stronger than ordinary dipole-dipole and dispersion forces, but weaker than true covalent and ionic bonds.

Unknown:

Mass of NaCl  = ?

Solution:

To solve the problem, we need to use the expression below;

    Mass of NaCl  = number of moles x molar mass

Molar mass of NaCl  = 23 + 35.5  = 58.5g/mol

So;

Insert the parameters and solve;

     Mass of NaCl  = 2 x 58.5  = 117g

Explanation:

Alkaline earth metals are group 2 metals on the periodic table. They are divalent elements because they have two valence electrons and ionize by donating these two valence electrons. Elements in this group have the same numbers of electrons in their outermost shell of their atoms. i.e. they all have the same number of valence electrons and ionic charge.

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.

Kilograms are the largest unit among the options listed.

The metric system is a decimal-based system of measurement widely used around the world. It provides a standardized and convenient way to express measurements by utilizing prefixes that represent powers of 10.

In the metric system, the base unit for measuring mass is the gram (g). The gram is a relatively small unit, and to express larger or smaller masses, prefixes are added to the base unit. Here are some commonly used metric prefixes for mass.

The largest measurement among the options provided is kilograms (kg). Kilograms are larger units of measurement compared to grams (g), milligrams (mg), and centigrams (cg). The metric system follows a decimal-based system, where each unit is 10 times larger or smaller than the adjacent unit.

1 kilogram (kg) is equal to 1,000 grams (g), 1,000,000 milligrams (mg), and 10,000 centigrams (cg). Therefore, kilograms are the largest unit among the options listed.

Answer:

13598 J

Explanation:

Q = m × c × ∆T

Where;

Q = amount of energy (J)

m = mass (grams)

c = specific heat capacity

∆T = change in temperature

m = 65g, specific heat capacity of water = 4.184J/g°C, initial temperature= 100°C, final temperature = 150°C

Q = 65 × 4.184 × (150 - 100)

Q = 271.96 × 50

Q = 13598 J

Hence, 13598 J of energy is required to boil 65 grams of 100°C water and then heat the steam to 150°C.

Answer:

650 grams

Explanation:

Given that acetylene gas reacts with oxygen to produce caobon dioxide, water and heat and the unbalnced equation is

[tex]C_2H_2(g)+O_2(g) \rightarrow CO_2(g) + H_2O(g)+ heat[/tex]

Gram-formula mass of [tex]C_2H_2= 26[/tex] g/mol

So, mass of 1 mole of acelylene is 26 grams

Therefore, mass of 25 moles of acelylene=25x26=650 grams

Hence, the mass of 25 moles of acelylene is 650 grams

The mass of 25 moles of acetylene has been 0.65 kg.

Moles are the count of a number of molecules in an entity and the mass based on the formula mass. 1 mole of a substance has [tex]\rm 6.023\;\times\;10^2^3[/tex] molecules.

The moles can be calculated as:

Moles = [tex]\rm \dfrac{weight}{molecular\;weight}[/tex]

Given, mole of acetylene = 25 mol

molecular mass of acetylene = 26 g/mol

Mass of acetylene = moles [tex]\times[/tex] molecular weight

Mass of acetylene = 25 [tex]\times[/tex] 26

Mass of acetylene = 650 grams

1000 grams = 1 kg

650 grams = 0.65 kg.

The mass of 25 moles of acetylene has been 0.65 kg.
