In the above equation how many moles of NO can be made when 43 moles of HNO3 are consumed?

Answer/Explanation:

The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.

Earth's surface warms up in the sunlight. At night, Earth's surface cools, releasing heat back into the air. But some of the heat is trapped by the greenhouse gases in the atmosphere. That's what keeps our Earth a warm and cozy 58 degrees Fahrenheit (14 degrees Celsius), on average.

Answer:

An acidic solution has a high concentration of hydrogen ions (H +start superscript, plus, end superscript), greater than that of pure water.

The acidic solution indicates the highest concentration of hydrogen or the proton ion in the solution.

Acidity is the measure of the hydrogen ion in the solution by the pH scale and gives the acidic or basic characteristics to the solution.

The concentration of the hydronium or the hydroxide in the solution is a way to determine the acidic basic nature and the pH and pOH of the solution.

Therefore, in an acidic solution hydrogen ions are in the greatest concentration.

Answer: It does not react with water, but reacts with most acids. It combines with oxygen at room temperature to form chromium oxide. Chromium oxide forms a thin layer on the surface of the metal, protecting it from further corrosion (rusting).

Explanation:

You know the number of moles of Mg that react: 6 moles.

You don't know (yet) how many moles of Mg₃N₂ are produced when 6 moles of Mg react.

The coefficients of each substance in the chemical equation tells us the molar ratio between the substances. The coefficient of Mg is 3, and the coefficient of Mg₃N₂ is 1 (coefficients of 1 are implied and omitted). So, for every 3 moles of Mg that react, 1 mole of Mg₃N₂ is produced.

We can use the proportion set up in the image to calculate the number of moles of Mg₃N₂ produced. In the first fraction, the green-boxed numerator should be our known number of moles of Mg, that is, 6 moles Mg. In the second fraction, we insert our molar ratio. Since we want the product of these two fractions to have the units "moles Mg₃N₂," the numerator in the second fraction should be 1 mole Mg₃N₂ and the denominator should be 3 moles Mg.

Our setup should look like this:

[tex]\frac{\textrm{6 moles Mg}}{1} \times \frac{\textrm{1 mole }\mathrm{Mg_3N_2}}{{\textrm{3 moles Mg}}} = \textrm{2 moles }\mathrm{Mg_3N_2}.[/tex]

Indeed, 2 moles of Mg₃N₂ are produced.

Answer:

The correct answer is - Frequency is the number of wavelengths, which is measured in hertz.

Explanation:

Frequency is the number of waves that go through a fixed point at a particular time. Hertz is the SI unit for frequency which means that one hertz is equal to a unit number of waver passes in a unit time to a fixed point.

As the frequency of a wave increases which means the number of waves increases in the unit time, the shorter the wavelength will be.

a higher frequency wave has more energy than a lower frequency wave with the same amplitude.

When tin metal is placed into a solution of nickel (II) iodide then nothing will occur.

Reactivity series of the metals tells about the increasing or decreasing orders of the reactivity of the metals.

According to the reactivity series, reactivity of nickel metal is more than the tin metal. So, if we add tin metal in the solution of nickel (II) iodide then no reaction occurs. Because the reactivity of tin is less as compare to nickel metal so it is not possible for tin to replace the nickel metal and get dissolve.

Hence, option (C) is correct i.e. nothing.

Explanation:

How many formula units are in 2.0 moles of Fe(NO3)2?

Mole measure the number of elementary entities of a given substance that are present in a given sample. 12.044×10²³ formula units are in 2 moles of Fe(NO₃)₂.

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number. Mole is inversely proportional to molar mass.

Mathematically,

Mole of Fe(NO₃)₂. =given number of atoms of Fe(NO₃)₂.÷ 6.022×10²³(Avogadro number)

mole of Fe(NO₃)₂= 2moles

Substituting the values

2=number of atoms of Fe(NO₃)₂.÷ 6.022×10²³

Number of atoms of Fe(NO₃)₂.=2×6.022×10²³

Number of atoms of Fe(NO₃)₂.=12.044×10²³

Therefore, 12.044×10²³ formula units are in 2 moles of Fe(NO₃)₂.

Explanation:

Forces are given many names, such as push, pull, thrust, lift, weight, friction, and tension. Traditionally, forces have been grouped into several categories and given names relating to their source, how they are transmitted, or their effects. The most important of these categories are discussed in this section, together with some interesting applications. Further examples of forces are discussed later in this text.

This is a Charles' Law problem: V1/T1 = V2/T2. As the temperature of a fixed mass of gas decreases at a constant pressure, the volume of the gas should also decrease proportionally.

To use Charles' Law, the temperature must be in Kelvin (x °C = x + 273.15 K). We want to solve Charles' Law for V2, which we can obtain by rearranging the equation into V2 = V1T2/T1. Given V1 = 25 L, T1 = 1200 °C (1473.15 K), and T2 = 25 °C (298.15 K):

V2 = (25 L)(298.15 K)/(1473.15 K) = 5.1 L.  

The volume of this gas will be "5.1 L".

Given:

             [tex]= 1473 \ K[/tex]

             [tex]= 298 \ K[/tex]

As we know,

→ [tex]\frac{V_1}{V_2} = \frac{T_1}{T_2}[/tex]

By substituting the values, we get

→ [tex]\frac{25 \ L}{V_2} = \frac{1473 \ K}{293 \ K}[/tex]

→    [tex]V_2 = \frac{25\times 298}{1473} \ L[/tex]

→         [tex]= 5.1 \ L[/tex]

D. ms=+1/2.

Explanation:

Hello there!

In this case, since the quantum numbers are known as:

* Principal quantum number (n) which cannot be zero. The allowed values of n are therefore 1, 2, 3, 4, and so on.

* Angular quantum number (l) is able to be any integer between 0 and n-1. If n = 2, for example, l can be either 0 or 1.

* Magnetic quantum number (m) is able to be any integer between -l and +l. If l = 3, m can be either -3, -2, -1, 0, +1, +2 or +3.

* Spin Quantum Number (ms): ms = +½ or -½. Accounts for the orientation of the spin axis of an electron as it is able to spin in only one of two directions.

Thus, since the fourth quantum number is ms, spin, we infer that the answer is D. ms=+1/2 because it represents the positive spin on 2s^2.

Answer:

Explanation:

A titration in general is used to determine the concentration of something with a solution of known solution. For acid, a base solution of known concentration is added slowly. The end-point is determined by using a pH indicator. When the acid is neutralized at the end, note the amount of base solution used and the strength of acid can be calculated.

Note that the quantity of base solution utilised and the acid strength can be estimated after the acid has been neutralised.

Titration is a method of chemical analysis where the quantity of a sample's constituents is established by adding a precisely measured amount of something else with which the component that is wanted will react in a specific, known proportion.

A burette, which is essentially a long, graded measurement tube with a stopper and a tube for injection at its bottom end, is used to gradually administer a standard solution of titrating reagent, and titrant, to a specified concentration. When the point of equal value is achieved, the addition is terminated. Note that the quantity of base solution utilised and the acid strength can be estimated after the acid has been neutralised.

Therefore, note that the quantity of base solution utilised and the acid strength can be estimated after the acid has been neutralised.
