Is this a balanced equation? 4NH3+ 5O2 – 4NO + 5H20​

As per the given question Mass of water produced = 2 mol × 18.015 g/mol= 36.03 gSo, if 1.0 mole of methane reacts with oxygen to produce carbon dioxide and water, then 36.03 grams of water will be produced.

The given reaction is: CH4 + 2O2 → CO2 + 2H2O The balanced equation tells us that one mole of methane reacts with two moles of oxygen gas to produce one mole of carbon dioxide and two moles of water.Since the reaction involves one mole of methane, we can say that it will produce two moles of water.

In order to determine the mass of water, we need to use the molar mass of water. It can be calculated as follows:

Molar mass of water (H2O) = 2(atomic mass of hydrogen) + atomic mass of oxygen

= 2(1.008 g/mol) + 15.999 g/mol

= 18.015 g/mol

Therefore, one mole of water has a mass of 18.015 g/mol.

.Now, we can use the following formula to calculate the mass of water produced:

Mass of water produced = Number of moles of water × Molar mass of water

Number of moles of water = 2 mol (from the balanced equation)

Molar mass of water = 18.015 g/mol (as calculated above)

Therefore,Mass of water produced = 2 mol × 18.015 g/mol= 36.03 gSo, if 1.0 mole of methane reacts with oxygen to produce carbon dioxide and water, then 36.03 grams of water will be produced.

Emerging scientific ideas are new theories or ideas that are gaining attention in the scientific community, but have not yet been fully accepted or confirmed.

Emerging ideas refer to the new and innovative ideas or theories that have yet to gain full scientific acceptance. While a scientific consensus is a view or theory that has been universally accepted and confirmed by multiple experiments or research, an emerging scientific idea is a new and unproven theory or idea that is gaining attention in the scientific community. These emerging ideas may also be referred to as scientific hypotheses. In contrast to scientific consensus, emerging scientific ideas have not yet been subjected to rigorous testing and confirmation.

They are generally proposed to explain new observations or experimental results, which have not yet been fully understood or explained by established scientific theories. Emerging scientific ideas can have the potential to challenge the current scientific consensus. If an emerging scientific idea is found to be valid, it can ultimately lead to the establishment of a new scientific consensus. For example, the emerging scientific idea of the Higgs boson particle led to the discovery of a new field in particle physics, which is now an established scientific consensus.

Given what we know, we can confirm that despite not being able to provide a visual representation, if you were to create one, it would show the atoms in the substance moving with more and more energy over time until vaporization occurred.

Therefore, given that vaporization is when atoms within a substance gain so much kinetic energy that they are able to rupture the bonds that hold them relatively close together and change into a gas, we can confirm that a visual representation would have to be a diagram showing the increased movement of atoms over time.

Answer: When the electrons in an element are more than the required, a bond is formed with other element which has deficiency of electron and in case when electrons are less in numbers the vice versa happens. Such kind of chemical bonds are known as ionic bond.

Explanation:

Answer:

A covalent bond is made between CH4.

Explanation:

See as There are four atoms in carbon's valence shell it need 4 more atoms to complete its valence shell or octet.Four hydrogen atoms will come and share there one electron with carbon atom.By sharing both atoms will gain stability and covalent bond is made in these atoms because covalent is made by share of electrons between two non metal elements and carbon is non metal and hydrogen is either metal and non metal.

Covalent bond, formed by sharing electrons, is formed between 1 carbon and 4 hydrogens- known as methane (\(CH_{4}\)).

Carbon has 4 electrons in it's valence shell. Since losing or gaining 4 more electrons to become stable requires too much energy which the carbon atom doesn't possess, it gains stability by forming a covalent bond.

Each of the four hydrogen atoms, having one electron in their valence shell, share it with the carbon and hence 8 electrons are there altogether in the sharing bond leading to stability.

Therefore, if you utilise water, you must have a barometer that is 13.534 times the length of a mercury barometer, which may be longer than 11 metres.

Additionally, mercury can reach the same temperature of the atmosphere more quickly than water since it has a lower specific heat than water and is a better heat conductor.

What is Barometer?

Barometer, a tool for calculating atmospheric pressure. A barometer can also be used to determine height because air pressure varies with elevation above or below sea level. Mercury and aneroid barometers are the two primary varieties.

A mercury column whose height can be precisely measured is balanced by atmospheric pressure in a mercury barometer. Mercury barometers are frequently adjusted for the local gravity value and the surrounding temperature in order to boost their accuracy.

as per ideal Gas Law equation, we can calculate the number of moles to be 0.0292 moles.

The number of moles of a gas can be calculated using the Ideal Gas Law equation, PV = nRT,

where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.

For the given sample, the pressure, volume, and temperature are 0.753 atm, 1.68 liters, and 2°C respectively.

By converting the temperature to Kelvin and plugging the values into the Ideal Gas Law equation, we can calculate the number of moles to be 0.0292 moles.

Number of moles = PV / RT

= 0.753 * 1.68 / (0.0821 * (275 + 2))

= 0.0292 moles.

One reason that we say that light is a wave is because light waves can travel through a medium.

A wave can be defined as a disturbance along a medium which transfers energy. It then follows that waves move energy from one point to another.

Waves can be classified as;

Mechanical waves are those waves that  require a material medium for propagation such as sound, and waves on a strings while electromagnetic waves do not require a material medium for propagation.

Light exhibits certain behaviors that are characteristic of any wave. Light reflects in the same manner that any wave would reflect. Light refracts in the same manner that any wave would refract. Light diffracts in the same manner that any wave would diffract. Light undergoes interference in the same manner that any wave would interfere. And light exhibits the Doppler effect just as any wave would exhibit the Doppler effect. Light behaves in a way that is consistent with our conceptual and mathematical understanding of waves. Since light behaves like a wave, one would have good reason to believe that it might be a wave.

Answer:

Explanation:

The equation for the reaction of lithium with water to produce lithium hydroxide and hydrogen gas is:

Li + H2O -> LiOH + H2

To balance this equation using the electron-transfer method, we first need to determine the oxidation states of each element in the reactants and products.

In Li, the oxidation state of lithium is +1. In H2O, the oxidation state of hydrogen is +1 and oxygen is -2.

In LiOH, the oxidation state of lithium is +1, oxygen is -2 and hydrogen is +1.

In H2, the oxidation state of hydrogen is +1.

It's clear that lithium loses 1 electron to become Li+ and hydrogen gains 1 electron to become H-.

So, we have to add an electron on the right side of the equation to balance the electrons.

Li + H2O -> LiOH + H2 + e-

Now, the number of electrons on both sides of the equation is the same and the equation is balanced.

Alternatively, we can use the oxidation number method, where we balance the charge of the reactant and product side of the equation. The sum of the oxidation numbers of all atoms on the reactant side must equal the sum of the oxidation numbers of all atoms on the products side. In this case, the oxidation state of lithium is +1, hydrogen is +1 and oxygen is -2.

Li + H2O -> LiOH + H2

+1 +1 -2 = +1 +1 +1 -2

The equation is already balanced with respect to oxidation numbers

Answer:

Caustic soda

Explanation:

The fractional distillation of air is carried out on liquid air. Before air is liquified, the carbon dioxide content of air is removed using caustic soda. The air is then compressed to a pressure of about 200 atm, sudden expansion of the gas leads to cooling. The process continues until air becomes liquid at  -200°C.

Fractional distillation of liquid air usually produces nitrogen and oxygen as major products. nitrogen in obtained first since it has a lower boiling point than oxygen. The gases are then dried, compressed and stored in cylinders.
