For the first part,

 Reaction equation:

         N₂  +  3H₂   →   2NH₃

Given:

Number of moles of NH₃  = 6 moles

Unknown:

Number of moles of N₂  = ?

Solution:

   N₂  +  3H₂   →   2NH₃;

  From the reaction above, we solve from the known specie to the unknown. Ensure that the equation is balanced;

         2 moles of NH₃ is produced from 1 mole of N₂

        6 moles of NH₃ will be produced from [tex]\frac{6}{2}[/tex]  mole of N₂

                                                                      = 3moles of N₂

The number of moles of N₂ is 3 moles

ii.

Given parameters:

Number of moles of sulfur = 2.4moles

Molar mass of sulfur  = 32.07g/mol

Unknown:

Mass of sulfur  = ?

Solution:

The number of moles of any substance can be found using the expression below;

 Number of moles  = [tex]\frac{mass}{molar mass}[/tex]

  Mass of sulfur  = number of moles of sulfur x molar mass

Insert the parameters and solve;

    Mass of sulfur  = 2.4 x 32.07  = 76.97g

Answer: B

Explanation: Covalent bonds where electrons are not shared equally between two atoms are called polar covalent bond. As shown above, the electrons in a covalent bond between two different atoms (H and Cl in this case) are not equally shared by the atoms. This is due to the electronegativity difference between the two atoms.

There are two types of chemical compound one is covalent compound and other is ionic compound in chemistry. The covalent bond will be formed between two chromium atoms. the correct option is option B.

Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.

Covalent bond formed by sharing of electron and ionic bond formed by complete transfer of electron.

Element with same electronegativity difference combine together by covalent bond whereas ionic bond is formed by elements whose electronegativity difference is high.

As two chromium is combining that is two two element with same electronegativity is combining therefore, formation of covalent bond is the only possibility.

Therefore covalent bond will be formed between two chromium atoms. the correct option is option B.

Answer:

A. ✔️Substitution

B. ✔️Insertion

C. ✔️Deletion

Explanation:

In A, the type of mutation that is shown is Substitution. In B, the type of mutation shown is Insertion and in C, the type of mutation shown is Deletion.

Mutation refers to the change in the DNA sequence. This occurs in an organism. In gene mutation, the structure of DNA molecule changes and produces a different allele of a gene. While in chromosome mutation, there is the change in the structure or number of the whole chromosomes in a particular cell.

Actually, mutations can take place both in prokaryotic cell and in eukaryotic cell.

In genetics, there are: Substitution, Insertion and Deletion mutations.

Substitution mutation is an exchange of one base for another. Insertion mutation is simply addition of one or more nucleotide pairs in a DNA sequence while Deletion mutation refers to the situation in which a sequence of DNA is left out when there is DNA replication.

Answer:

A. Substitution

B. Insertion

C. Deletion

Explanation:

A. There is a replacement in C G there is A T.

B. There is one more base.

C. There are 8 base there should be 9.

Answer:

936g/mol

Explanation:

To find the molar mass of a molecule, you find the sum of the molar masses of each atom in the molecule.

This compound has 40 carbon atoms, 60 Hydrogen atoms, 10 Nitrogen atoms, 12 Oxygen atoms, and 2 Sulphur atoms.

The molar mass of:

[tex](12 \times 40) + (60 \times 1) + (14 \times 10) + (16 \times 12) + (32 \times 2) = 936[/tex]

Answer:

B. Density stays the same no matter how much of a substance there is.

Explanation:

Density of the substance is the same and it is the measure of its mass per unit volume. Thus, the mass of titanium per  1 cm³  is 4.506 g which is the same for 10 g, 100 g or whatever the mass.

Density of a substance is the measure of its mass per unit volume. It describes how closely its particles are packed.  Density of an object depends on its bond type, temperature and pressure.

The more denser the object is , more will be its mass distribution per unit volume. Substances denser than water will sink on it otherwise they float on water.

Density is constant for a substance, the distribution of given mass per unit volume is same for all masses. Hence, the density of 100 g Ti is same as that of 10 g. i.e., 4.56 g/cm³.

Answer: surface temperature

Explanation:

Answer:

air

Explanation:

The main source of oxygen molecules is the air around us. Air is made up of 21% of oxygen gas which is the second most abundant gas found in the atmosphere.

Ions can be made by single element or covalently bonded group of elements. The covalently bonded group of elements is called polyatomic ion. Therefore, when an atom forms a negative ion, atom become cation.

Any species that contain charge whether it is positive charge or negative charge is called ions. The example of polyatomic ions are sulfate, phosphate, nitrate etc.

Cation is the species that loose electron and attain positive charge while anion is a species which gain electron and attains negative charge so when anion and cation combine in fixed ration the the overall charge of the molecule is zero that is molecule is neutral, the charge over cation and anion is also called oxidation state. When an atom forms a negative ion​, then atom itself gain positive charge over it and become cation by loosing electron.

Therefore, when an atom forms a negative ion, atom become cation.

Answer:

In the chemical bonds.

Explanation:

There are different types of chemical bonds, some store a TON of energy while others do not store as much. You can think of it like this: for bonds with low energy, it takes a LOT of force to pull them apart, meaning they are strong bonds. However, this way, you have to put energy into them to break the bonds and form a chemical reaction. This is an endothermic reaction, a reaction that absorbs heat from its surroundings.

Instead, bonds in exothermic reactions are BEGGING to form a more stable bond, and hence store a lot of potential energy. Due to the difficulty of maintaining these bonds, there is a lot of energy put into them. If you break them, however, (exothermic reaction) the energy is released, and hence the exothermic reaction happens.

Answer:

30 N

Explanation:

To find force you multiple mass by acceleration. If you multiple 10kg by 3 m/s you then get 30 N.

Answer:

30 N

Explanation:

Force can be found by multiplying the force by the acceleration.

F=m*a

The mass of the bowling ball is 10 kilograms. The acceleration is 3 meters per second squared.

• m= 10 kg

• a= 3 m/s^2

Substitute the values into the formula.

F= 10 kg * 3 m/s^2

Multiply.

F= 30 kg*m/s^2

• 1 kilogram meter per second squared is equal to 1 Newton.

• Therefore our answer of 30 kg*m/s^2 is equal to 30 Newtons.

F= 30 N

The correct answer is B. 30 Newtons.
