Measles is a communicable disease that requires immunization to prevent illness when exposed to it.

Measles is a communicable disease and highly contagious. It  is usually very serious in children. The disease can be contacted through droplets in the air, physical contact and through mother-to-child transmission.

It is a very serious disease as it is caused by a virus which replicates very fast in the throat and nose thereby creating symptoms such as runny nose, coughing, sneezing and is usually accompanied with a rash.

The severity and death rates is what gave rise to the creating of a measles vaccine which is usually given to babies after birth to make them immune to the potential exposure to the virus.

Diabetes, bronchitis and strep throat have no vaccine as they can always be treated or managed with over-the-counter drugs.

Answer: Matter cannot be created or destroyed in chemical reactions.

Explanation: This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.

It is appropriate to form double or triple bonds in a Lewis structure when four or six electrons are shared.

A Lewis structure is a representation of a molecule using dots to show the valence electrons in the molecule. This dots are shown around the symbols of the elements.

However, in instances where four or six electrons are shared between bonding atoms, a double or triple bond is used. A double bond means that four electrons are shared. A triple bond means that six electrons are shared.

Answer:B

Explanation:

A positively charged object attracts an uncharged object.

A positively charged object attracts an uncharged object statement is in correct in the table. Hence option B is correct.

Charge are defined as a subatomic particle's ability to experience force when exposed to an electric and magnetic field. The value that the atom reaches after removing or gaining electrons is known as charge. Only ions that comply with the octat rule are stable. Atoms or groups of atoms with an electric charge are referred to as ions. Cations are positive-charged ion particles. Anions are ion types that have a net negative charge.

A charged object will cause an opposing charge to be applied to an uncharged object when it is brought close to the charged one. These two things are drawn to one another because opposing charges attract one another. Other charged items are drawn to a charged object whereas uncharged objects are repelled by it.

Thus, a positively charged object attracts an uncharged object statement is in correct in the table. Hence option B is correct.

CaCO3 --> CaO + CO2

0,2 ----------------> 0,2

nNaOH = 0,5.0,56 = 0,28 mol

=> T = nNaOH/nCO2 = 0,28/0,2 = 1,4

=> sản phẩm tạo ra bao gồm : Na2CO3 và NaHCO3

NaOH + CO2 --> NaHCO3

Explanation:

The mass of ammonia that would be produced is 312.5 g

First, we will write a balanced chemical equation for the reaction

The balanced chemical equation for the reaction is

3H₂(g) + N₂(g) → 2NH₃(g)

This means

3 moles of hydrogen gas reacts with 1 mole of nitrogen gas to produce 2 moles of ammonia.

First, we will determine the number of moles of each reactant present

For Hydrogen (H₂)

Mass = 83.6 g

Molar mass = 2.016 g/mol

Using the formula

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

Number of moles of H₂ present = [tex]\frac{83.6}{2.016}[/tex]

∴ Number of moles of H₂ present = 41.468254 moles

For Nitrogen (N₂)

Mass = 257 grams

Molar mass = 28.0134 g/mol

∴ Number of moles of N₂ present = [tex]\frac{257}{28.0134}[/tex]

Number of moles of N₂ present = 9.174181 moles

Since,

3 moles of hydrogen gas reacts with 1 mole of nitrogen gas to produce 2 moles of ammonia

Then,

27.522543 moles of hydrogen gas will react with the 9.174181 moles of nitrogen gas to produce 18.348362 moles of ammonia

∴ 18.348362 moles of ammonia will be produced during the reaction

Now, for the mass of ammonia that would be produced

From the formula

Mass = Number of moles × Molar mass

Molar mass of ammonia = 17.031 g/mol

Mass of ammonia that would be produced = 18.348362 × 17.031

Mass of ammonia that would be produced = 312.49095 g

Mass of ammonia that would be produced ≅ 312.5 g

Hence, the mass of ammonia that would be produced is 312.5 g
