Explain how airbag gets deployed ? Explain the reactions involved?

Answer:

1. Covalent Bond

2. Ionic Bond

Explanation:

Covalent bonds are defined as the bond in which sharing of electrons takes place between atoms. The sharing of electrons is in equal number so that it form a stable balance of attraction and repulsion between atoms. In the given example of CO2 (first image) oxygen is sharing equal number of electrons with carbon to form a stable bond called covalent bond.

Ionic bonds are formed when valence electrons are transferred to other atoms and form oppositely charged ions. In ionic bond formation, the atoms that gain electrons become negatively charged and the atoms that loses electrons become positively charged. In the given example of Ca Cl2, Ca is also giving its 2 valence electrons to each Cl and there is no stable balance of attraction and repulsion between atoms.

Hence, the correct answer is:

1. Covalent Bond

2. Ionic Bond

Answer: gravitational energy

Explanation: If you have a book on a table and it might fall, its using gravitational energy because its depending on gravity to choose rather it will fall or just balance. It also depends on how high the object is off the ground

Answer:

Up to [tex]18\; \rm mol[/tex] [tex]\rm CO_2[/tex].

Explanation:

The equation for this reaction: [tex]2\; \rm C_3 H_7 OH + 9\; O_2 \to 6\; CO_2 + 8\; H_2O[/tex] is indeed balanced.

Notice that the coefficient of [tex]\rm C_3 H_7 OH[/tex] is [tex]2[/tex] while that of [tex]\rm CO_2[/tex] is [tex]6[/tex].

Therefore, each unit of this reaction would consume [tex]2[/tex] units of [tex]\rm C_3H_7OH[/tex] while producing [tex]6[/tex] units of [tex]\rm CO_2[/tex]. In other words, this reaction would produce three times as much [tex]\rm CO_2\![/tex] as it consumes [tex]\rm C_3H_7OH\![/tex].

If all that [tex]6\; \rm mol[/tex] of [tex]\rm C_3H_7OH[/tex] molecules are actually consumed through this reaction, three times as many [tex]\rm CO_2[/tex] molecules would be produced. That corresponds to [tex]3 \times 6\; \rm mol = 18\; \rm mol[/tex] of [tex]\rm CO_2\![/tex] molecules.

Answer:

You can observe a real-life application of Boyle's Law when you fill your bike tires with air. When you pump air into a tire, the gas molecules inside the tire get compressed and packed closer together. This increases the pressure of the gas, and it starts to push against the walls of the tire.

Tyres of untouched vehicles get deflated during freezing winter days while get inflated in hot summer days. This unusual behaviour is because of Charles's law. In winter due to low temperatures, the air inside a tyre gets cooler, and they shrink. While in hot days, the air expands with temperature.

Another common example of Avogadro's law is the deflation of automobile tyres. When the air trapped inside the tyre escapes, the number of moles of air present in the tyre decreases. This results in a decrease in the volume occupied by the gas, causing the tyre to lose its shape and deflate.

Nitrogen N2 has a non polar covalent bond.

Water  H2O has polar covalent bonds between the H and O atoms.

Stronger intermolecular forces = higher boiling point​

The stronger the intermolecular forces, the harder the molecules are to pull/break apart, which means a higher boiling point.

Answer:

17.25 L

Explanation:

I converted 100g into moles and converted the amount of moles into L.

1 mole is equal to 6.023 × 10 ²³ molecules.17.25 Liters are in 100 grams of COCl₂. Therefore, option D is correct.

The term mole is defined as the amount of substance of a system which contains as many elementary entities.

One mole of any substance is equal to 6.023 × 10²³ units of that substance such as atoms, molecules, or ions. The number 6.023 × 10²³ is called as Avogadro's number or Avogadro's constant.

The mole concept can be used to convert between mass and number of particles.

1 gram of COCl₂ =  0.00770 mole

100 gram COCl₂ = 0.770 mole

To convert gram into litre multiply by 22.4

= 0.770 ×  22.4

= 17.25 Litre

Thus, 17.25 Liters are in 100 grams of COCl₂, option D is correct.

Answer:Chlorine

Explanation:

This isotope is Chlorine because an atom with 17 protons will always be chlorine, just as an atom with 1 proton will always be hydrogen, for example

Answer:

3.02x10²⁴

Explanation:

To solve this problem we need to use Avogadro's number: It is the number of units (usually atoms or molecules, in this case it's trucks) contained in one mol: 6.023x10²³.

We multiply the given number of moles times Avogadro's number:

5 * 6.023x10²³ = 3.02x10²⁴

So five moles of trucks would be 3.02x10²⁴ trucks.

Molar mass = 216.8254 (approx.)

Explanation:

Given:

FeCl2 • 5H20

Find:

Molar mass

Computation:

Atomic mass

Fe = 55.845

Cl = 35.453

H = 1.00794

So,

FeCl2 • 5H20

55.845 + 2(35.453) + (2)5(1.00794) + 5(15.999)

55.845 + 70.906 + 10.0794 + 79.995

Molar mass = 216.8254 (approx.)

This question is incomplete, but it can be answered based on general knowledge of the topic. The answer is RED

Explanation:

This question is describing a gene that codes for color. The allele for red color is R while that of white is r, however, these two alleles exhibit incomplete dominance to form an intermediate phenotype that is PINK (Rr).

Since the heterozygous is pink color, it will take two red alleles to make a plant phenotypically red i.e RR. Note that, genotype "rr" will be white.
