When a molecule can occupy the same active site as the substrate, a situation called __________________ can result.

Neutrons don't have a charge. They are neutral

Taking into account the definition of ato, proton, neutron and electron, the correct answer is second option: The one particle that does NOT have a charge is the neutron.

You must know the atom is defined as the smallest particle into which an element can be divided without losing its chemical properties.

Atoms are made up of extremely small particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom and form the nucleus, while electrons surround the nucleus.

Electrons have a negative charge, while the charge of protons is positive. The only ones that have no electrical charge are neutrons.

In this way, the atomic nucleus has a positive charge in which almost all its mass is concentrated, while around the atomic nucleus, there are a certain number of electrons, negatively charged.

Finally, the correct answer is second option: The one particle that does NOT have a charge is the neutron.

Answer:

gas chromatograph

Explanation:

I took the test and got it right.

Answer:

In a chemical reaction, equilibrium is achieved when the forward and reverse reactions occur at the same rate.

Equilibrium is influenced by the following:

1) pressure

2) temperature

3) concentration

Bear in mind that CATALYST HAS NO IMPACT ON THE EQUILIBRIUM; IT ONLY INCREASES THE RATE.

PRESSURE:

Only if the reaction's left side contains a greater number of molecules can the pressure be increased in order to boost yield. [tex]{e.g:N}_2+3H_2\rlhar2NH_3[/tex]

Thus, because the left side has four molecules and the right side has two, you should increase pressure to increase yield.

TEMPERATURE:

In order to increase yield, raise the temperature only in ENDOTHERMIC FORWARD reactions.

CONCERNTRATION:

Removing the formed product increases yield.

Answer:

- The conjugate base of a weak acid is a strong base.

-  The conjugate base of a strong acid is a very weak base

Explanation:

The conjugate base of a strong acid is a very weak base, and the conjugate base of a weak acid is a strong base. These two statements are true.

It is a substance with the capacity to take a proton out of an extremely weak acid. In water, they can also entirely separate into its ions. Examples include sodium hydroxide and potassium hydroxide (KOH) (NaOH).

The stronger the acid and the weaker its conjugate base are, the higher the Ka. Similar to this, the stronger a material is as a base and the weaker its conjugate acid's acidity, the higher the Kb.

Bases provide a similar problem: a strong base is one that is completely ionized in solution. A weak base is one that is less than 100% ionized in solution. There aren't many strong bases, and any base that isn't on the list is.

Thus, The conjugate base of a strong acid is a very weak base, and the conjugate base of a weak acid is a strong base.

The empirical formula for a aluminum compound containing oxygen (AlxOy), if 4.78g of Al reacts is Al3O2.

According to this question, 4.78g of Al reacts with oxygen to form a total mass of 6.67g. This means that the mass of oxygen that reacted is 6.67 - 4.78 = 1.89g

First, we convert each mass to moles

Next, we divide each value by the smallest

Multiply each value by 2

Al = 2.8 = 3

O = 2

Therefore, the empirical formula for a aluminum compound containing oxygen (AlxOy), if 4.78g of Al reacts is Al3O2.

Explanation:

T1 = 505 K

P1 = 105.3 kPa = 1.04 atm

V1 = 0.250 L

T2 = 495 K

P2 = 100.3 kPa = 0.990 atm

V2 = ?

495 x 1.04 x 0.250 ÷ 505 ÷ 0.990 = V2

V2 = 0.257 L

So 0.257 L is the answer!!

Answer:

2 oxygen atoms make oxygen gas

A molecule of oxygen gas is composed of two oxygen atoms chemically bonded together. The symbol for oxygen is "O," and the atomic number is 8, indicating that each oxygen atom has 8 protons in its nucleus.

A covalent bond is a type of chemical bond that occurs between two atoms when they share one or more pairs of electrons. It is a strong bond that holds atoms together to form molecules.

In a covalent bond, atoms share electrons in order to achieve a more stable electron configuration, typically by filling their outermost energy levels (valence shells). By sharing electrons, both atoms involved in the bond can achieve a more stable configuration, similar to the noble gas configuration.

In an oxygen gas molecule, the two oxygen atoms are held together by a covalent bond. Covalent bonds involve the sharing of electron pairs between atoms. In the case of oxygen gas, each oxygen atom shares two electrons with the other oxygen atom, resulting in a stable molecule.

Therefore, a molecule of oxygen gas is made up of two oxygen atoms (O) bonded together by a covalent bond.

yes because wet is water

Answer: Being a liquid, water is not itself wet, but can make other solid materials wet. Wetness is the ability of a liquid to adhere to the surface of a solid, so when we say that something is wet, we mean that the liquid is sticking to the surface of a material.

The best example of a chemical reaction that has a gas as a product is baking soda in vinegar.

Answer:

The color of light in which plants are less likely to produce food is green.

Explanation:

Photosynthesis is the process by which plants take advantage of sunlight to convert it into chemical energy, necessary to manufacture their nutrients, their growth and development.

Plants do not absorb all the colors of the light spectrum, since due to their pigments they absorb colors with specific wavelengths. Green plants do not absorb the color green, but reflect it —due to the chlorophyll pigment— which gives the green color to those leaves.

For this reason, the light that plants take least advantage of to produce food is green light.

Other options:

    The colors blue, orange and red can be absorbed by the plant, to a lesser or greater degree.

A. The mass of the oxygen gas collected is 0.317 g

B. The mass of potassium chlorate that decomposed is 0.81 g

The number of mole can be obtained as by using the ideal gas equation as illustrated below:

n = PV / RT

n = (0.973 × 0.25) / (0.0821 × 299)

n = 0.0099 mole

Thus the mass of oxygen collected can be obtained as follow:

Mass of oxygen = mole × molar mass

Mass of oxygen = 0.0099 × 32

Mass of oxygen = 0.317 g

Balanced equation

2KClO₃ —> 2KCl + 3O₂

From the balanced equation above,

3 moles of O₂ were obtained from 2 moles of KClO₃

Therefore

0.0099 mole of O₂ will be obtained from = (0.0099 × 2) / 3 = 0.0066 moles of KClO₃

Thus, the mass of KClO₃ that decomposed can be obtained as follow:

Mass = mole × molar mass

Mass of KClO₃ = 0.0066 × 122.5

Mass of KClO₃ = 0.81 g
