What other factors of weather and climate are affected by elevation?

Answer:

1.5 moles

Explanation:

The equation of the reaction is given as:

2 MnO2 + 4 KOH + O2 --> 2KMnO 4 + 2KOH + H2

From the equation,

2 moles of MnO2 produces 2 moles of KMnO4

x moles of MnO2 would produce 1.5 moles of KMnO4

2 = 2

x = 1.5

Solving for x;

x = 1.5 * 2 / 2

x = 1.5 moles

Answer: 4 ATP molecules is produced in the glycolysis of 2 glucose molecules

The first stage of most carbohydrate catabolism, which is described as the breakdown of larger molecules into smaller ones, is glycolysis, which is a part of cellular respiration. Two Greek words that mean "to break down anything sweet" are the source of the word glycolysis. Two molecules of ATP are created during the breakdown of glucose and formation of pyruvate during glycolysis.

Explanation:

2 ATP are produced.

For every glucose molecule, meaning that for every 2 glucose molecules, 4 ATP will be created.

A balanced nuclear equation for power generation by nuclear fission is given below:

The process of nuclear fission involves the splitting of an atom's nucleus into two or more smaller nuclei. Even by the energetic standards of radioactive decay, the fission process releases a very high quantity of energy and frequently results in gamma photons.

Nuclear fission is applied in nuclear power generation in a nuclear reactor.

The fissionable nuclear material is separated in the nuclear reactor so that a critical mass cannot exist, and the neutron flux and absorption are controlled to stop the fission reactions. The energy released during fission processes in a nuclear reactor used to generate electricity is trapped as thermal energy and used to heat water and create steam. The steam is utilized to turn a turbine, which powers an electricity-generating generator.

Answer:

64.2 L

Explanation:

In order to be able to calculate the volume of oxygen gas produced by this reaction, you need to know the conditions for pressure and temperature.

Since no mention of those conditions was made, I'll assume that the reaction takes place at STP, Standard Temperature and Pressure.

STP conditions are defined as a pressure of

100 kPa

and a temperature of

0

∘

C

. Under these conditions for pressure and temperature, one mole of any ideal gas occupies

22.7 L

- this is known as the molar volume of a gas at STP.

So, in order to find the volume of oxygen gas at STP, you need to know how many moles of oxygen are produced by this reaction.

In the molecule C2H4, valence orbitals of the carbon atoms are assumed to be e) sp^2 hybridized.

The set of orbitals that can energetically accept electrons to create chemical bonds is known as the valence shell. The ns and np orbitals in the outermost electron shell make form the valence shell for main-group elements.

The outside electrons engaged in bonding are called valence electrons. A particular atom can have 0 to 7 valance electrons since valance electrons can only exist in the s and p orbitals. Noble gases are atoms that have no valence electrons and dislike forming bonds.

First, we must compute the index of hydrogen deficiency, IHD, using the molecular formula of the compound [tex]C_{10}H_{14}O_{2}[/tex].

What is a spectrum data?

Spectrum data is data collected from spectroscopic experiments, which measure the interaction of matter with electromagnetic radiation. This data can be used to identify the chemical composition of a sample, as different elements and molecules absorb and emit radiation at different wavelengths.

Then, number of C atoms - [tex]\frac{number of atoms}{2} + 1[/tex]

                                          = [tex]10 + \frac{14}{2} + 1[/tex]

                                          = [tex]4[/tex]

Based on the molecular structure, this tells us how many multiple bonds and rings the compound has.

This compound contains four unsaturated bonds. We can tell from the spectrum data that it is aromatic (chemical shifts above 6 comes from aromatic protons). Based on this, we can conclude that the structure of this compound contains a benzene ring. Four IHD are found in the benzene ring, one from the ring and three from double bonds.

Following that, IR spectrum data revealed that absorption on [tex]3150-2850 cm^{-1}[/tex] indicated hybridised CH bonds.

The following chemical shifts are observed in the NMR spectrum data:

On 1,4ppm, it becomes a 6H triplet. It has two protons in its neighbourhood because it is a triplet, and it comes from [tex]CH_{3}(1)[/tex]. This group must be linked to the [tex]CH_{2}(2)[/tex].

A quartet on 4,0ppm, belongs to 4H from [tex]CH_{2}(2)[/tex].  It has 3 protons in neighborhood stop it it attached to the [tex]CH_{3}(1)[/tex] and singlet on 6,8ppm comes of aromatic protons, 4H (3).

Answer:

0.89 times

Explanation:

Let the initial volume of the tank be V.

Finally, we shall determine how much larger the final volume of the gas will be. This is illustrated below:

Initial pressure (P₁) = 130 kPa

Initial volume (V₁) = V

Final pressure (P₂) = 145.5 kPa

Final volume (V₂) =?

P₁V₁ = P₂V₂

130 × V = 145.5 × V₂

130V = 145.5 × V₂

Divide both side by 145.5

V₂ = 130V / 145.5

V₂ = 0.89V

Therefore, the final volume of gas will be 0.89 times the initial volume.

Wavelengths are being recorded by the machine by using IR spectrography. Therefore, option B is correct.

Infrared (IR) spectroscopy is also known as infrared spectrometry. It is a technique that is used to analyze and identify chemical compounds based on their absorption or emission of infrared radiation.

Infrared radiation lies in the electromagnetic spectrum between visible light and microwave radiation. It has longer wavelengths and lower frequencies than visible light. When infrared radiation passes through a sample, certain chemical bonds in the sample absorb specific frequencies of infrared light.

Answer:

Mg + 2HCl=== Mg(Cl)2 + H2

The Reaction is a single displacement reaction.

Yes!

This reaction obeys the law of conservation which states that for a closed system... Matter and energy transfer is constant.

Meaning that the Mass of products must equal mass of Reactants

To prove this

lets Calculate the Mass of reactants

24g + 73g=97g.

Mass of Products...

95g + x.

let's calculate the mass of Hydrogen produced.

Note: You can get it using any of the reactants... I'll use Magnesium

Now from the balanced reaction.... 1mole of Mg reacts to produce 1mole of Hydrogen

Moles of Mg=Mass/Molar Mass

Given Mass=24g

Molar mass of Mg=24

Mole of Mg =24/24

=1mole

Since Mole ratio of Mg and H2 is 1:1.... Therefore 1Mole of Hydrogen is produced too.

To get Mass of H2

Again

Mole=Mass/Mm

Known= 1mole of H2 isproduced

Mass of H2 =2g

Mole=Mass/Mm

Mass =Mole x Mm

= 1 x 2

=2g

Now

Total Mass of products is

95 +2 = 97g.

This is the same with the Mass of Reactants

So The Law of Conservation of Mass Holds.

Two covalent bonds are formed by oxygen to complete their octet.

An electron exchange that results in the formation of electron pairs between atoms is known as a covalent bond. Bonding pairs or sharing pairs are the names given to these electron pairs. Covalent bonding is the stable equilibrium of the attractive and repulsive forces between atoms when they share electrons.

In chemistry, an octet is an arrangement of eight electrons in the outer electron shell of a noble gas atom. The relative inertness of noble gases and the chemical behaviour of several other elements are attributed to this structure.

The chemical element oxygen has an atomic number of 8. (it has eight protons in its nucleus). At normal temperatures and pressures, oxygen transforms into the chemical compound (O2) of two atoms, which is a colourless gas.

Answer:

PROPYL ETHANOATE (OR PROPYL ACETATE)

Explanation:

1st step: Identify the functional group of the compound.

             COO is present, hence it is an ester.

2nd step: Split up the compound into CH3COOH and CH3CH2CH2OH.

                 Comes from ethanoic acid and propanol

3rd step: Join the names of the alcohol and the carboxylic acid together.

               Hence, propyl ethanoate.

In the modern periodic table, reactivity increases when moving from left to right in the third period because metallic character decreases along a period.

The elements in the modern periodic table are arranged in  7 periods and 18 groups in a certain manner such that along a period , the metallic character of the element decreases and non-metallic character increases while on moving from top to bottom in a group, the metallic character increases and non-metallic character decreases.

The metallic character of elements depends upon its ability to lose electrons. Along a group, the size of atom increases and gradually the nuclear pull decreases so they can readily lose electrons but across a period, atomic size decreases and nuclear pull increases so they cannot lose electrons easily.
