Answer:

The greater the number of hydrogen ions, the increase in the acid strength.

Explanation:

Hydrogen ions determine the pH of the acid, greatest number of hydrogen ions give the pH value below 4 hence strong acid, and least number of hydrogen ions give a pH value above 4 but less than 7 hence a weak acid

Answer:

Explanation:

Here is an illustration showing how to "calculate" +5 as the effective nuclear charge (Zeff) for phosphorus. We are not implying that the electrons are in orbits here, this is simply showing inner shell electrons that shield the outer valence electrons from the full nuclear charge.

We have that The effective nuclear charge Z_{eff} of 3p electron in phosphorus atom is discovered to be approximately 4.80

[tex]Z_{eff}=4.8[/tex]

It is important to note that the Z_{eff} of an element can be defined simply as the average positive charge felt by an shell electron in an atom from the various electrons around it

Hence

The effective nuclear charge Z_{eff} of 3p electron in phosphorus atom is discovered to be approximately 4.80

Answer:

The correct answer is - Luster.

Explanation:

Luster is a property that explains how the light is reflected on the surface of a mineral. Luster can be categorized with the help of if an element or mineral is metallic or non-metallic.

Pyrite has a shiny, opaque metallic luster which is similar to other metals. There are different types of luster other than metallic also found like, silky, dusty, pearly, waxy, and a few more.

Answer:

When the Sun's energy moves through space, it reaches Earth's atmosphere and finally the surface. This radiant solar energy warms the atmosphere and becomes heat energy. This heat energy is transferred throughout the planet's systems in three ways: by radiation, conduction, and convection.

Explanation:

Answer:

The sun radiates energy in all directions. Most of it dissipates into space, but the tiny fraction of the sun's energy that reaches Earth is enough to heat the planet and drive the global weather system by warming the atmosphere and oceans. The delicate balance between the amount of heat Earth receives from the sun and the heat that Earth radiates back into space makes it possible for the planet to sustain life.

Answer: This law states that the volume and temperature of a gas have a direct relationship: As temperature increases, volume increases, when pressure is held constant. Heating a gas increases the kinetic energy of the particles, causing the gas to expand

Explanation:

According to this law, a gas's volume and temperature are directly correlated: When pressure is held constant, volume rises as temperature rises. The kinetic energy of the particles in a gas increases when it is heated, which causes the gas to expand.

According to Boyle's Law, when the temperature and mass are both constant, the volume of a given volume of gas sustained at a constant temperature varies inversely with the applied pressure.

The quantity of gas particles, the volume of the container, and the temperature of the gas all affect the pressure of a gas that is confined. The pressure will rise as the amount of gas particles in a container increases. The pressure will rise as a container's volume increases.

Answer:

Reaction between an oxygen and  a phosphorus will produce oxides of phosphorus.

Explanation:

Reaction between oxygen and phosphorus produces four atoms of phosphorus with five atoms of oxygen. Sometimes it produces two atoms of phosphorus and five atoms of oxygen and sometimes four atoms of phosphorus and six atoms of oxygen. It does so depending upon the availability of oxygen. The size of phosphorus atom  interferes with the ability to form a double bonds to the other elements, such as nitrogen, oxygen, etc.

Answer:

See explanation

Explanation:

Accidental overlap of signals are common in H-1 NMR than in C-13 NMR for the following reasons;

1) 13C has a very low  natural abundance compared to H-1

2) 13C nucleus is s many times lesser in NMR sensitivity than H-1 nucleus.

3) As a result of its low abundance,  13C-13C coupling is not common.

4) Longer relaxation times do not give room for integrations.

5) Peaks in 13C spectra mainly consists of single lines.

As a result of all these, 13C-NMR spectra take longer to acquire than H-NMR. Hence, accidental overlap of signals is much more common in H-1 NMR than in C-13 NMR.

Answer:

A. when winds are to strong

B. cool tempatures

Explanation:

The rate of a reaction would be one-fourth.

Given

Rate law-r₁ = k [NO]²[H2]

Required

The rate of a reaction

Solution

The reaction rate (v) shows the change in the concentration of the substance (changes in addition to concentrations for reaction products or changes in concentration reduction for reactants) per unit time.  

Can be formulated:  

Reaction: aA ---> bB  

[tex]\large{\boxed{\boxed{\bold{v~=~-\frac{\Delta A}{\Delta t}}}}[/tex]

or  

[tex]\large{\boxed{\boxed{\bold{v~=~+\frac{\Delta B}{\Delta t}}}}[/tex]

The concentration of NO were halved, so the rate :

[tex]\tt r_2=k[\dfrac{1}{2}No]^2[H_2]\\\\r_2=\dfrac{1}{4}k.[No]^2[H_2]\\\\r_2=\dfrac{1}{4}r_1[/tex]

Answer:

C. The rate would be one-fourth.

Another option would be:

The rate would be four times larger

Explanation:

A salt bridge is necessary to keep the charge flowing through the cell. Without a salt bridge, the electrons produced at the anode would build up at the cathode and the reaction would stop running.
