Because root mean square velocity '=((3RT)/(M))(1/2)', CO' gas is a gas. For example, "RMS prop ((1)/(M))(1/2)" The highest "RMS" velocity is exhibited by "CO," which has the lowest molecular mass.

Alternating currents and voltages are one of the main areas where RMS values are applied. An AC voltage's value continuously fluctuates between zero and its positive peak, through its negative peak, and back to zero. The RMS value is the accurate measurement of a fluctuating voltage or current. The square root of the temperature and the molar mass have direct and inverse relationships with the rms velocity, respectively. Thus, increasing the temperature of a gas by fourfold causes the molecules' average motion to double.

D. electrons and protons

Each of the subatomic particles that make up the atom has a different charge.

Subatomic Particles

Firstly, remember that subatomic means smaller than the atom. There are 3 subatomic particles that make up the atom: the neutron, proton, and electron. The neutron has no charge, also known as a neutral charge. The proton is positively charged. The electron is negatively charged. The proton and neutron are located in the nucleus, and the electrons orbit the nucleus.

Attractions

The reason that electrons orbit the nucleus is due to the opposite charges of the proton and electron. The positive charge of the protons attracts the negative charge of the electron toward the nucleus. As the electrons move quickly around the nucleus, the attractive forces keep the electrons near the atom. The opposite charges and subsequent attraction of protons and electrons are the cause of many chemical reactions.

The chemical symbols for three different atomic cations that all have 23 protons are V²⁺ ; V³⁺ ; V⁴⁺ ; V⁵⁺.

An ion with positive charge is known as a cation, and this means that it has more protons (positively charged particles) than electrons (negatively-charged particles). When an atom loses one or more electrons, cations are created because the negatively charged electron or electrons are lost, leaving a positive charge on the atom overall.

Keep in mind that cations are positive ions; they are positively charged as a result of having lost one or more electrons and consequently possessing a higher number of protons than electrons. Anions are negative ions, having more electrons than protons due to the fact that they have gained one or more electrons.

O The NaCl will fail to dissociate. is NOT true. When solid NaCl is stirred into water, it will dissociate, meaning it will separate into individual sodium and chloride ions, which will make the solution conduct electricity and taste salty.

When a solid ionic compound dissolves, there is a process known as dissociation that separates the ions. The ability to formulate dissociation equations is crucial. Simply reverse the crisscross technique you learnt to use when writing ionic compound chemical formulas.

Dissociation is the process by which chemical molecules (or ionic compounds like salts, or complexes) disintegrate into simpler components like atoms, ions, or radicals. This process is typically reversible, as it is for CO2 and H2O at high temperatures.

Association and recombination are opposed by dissociation.

Answer:A mole is a way of counting things, in the case of chemistry those things are molecules.

But the number of things is a chemical reaction are not necessarily preserved: some reactions create more molecules (electrolysis of water (H2O), for example, starts with two molecules of water but delivers one molecule of oxygen gas (O2) and two molecules of hydrogen gas (H2)).

So moles are not conserved if the structure of the molecules changes because of the reaction. The point of writing equations is to match conservation of matter (atoms don't disappear) to the structures of the molecules involved in the reaction. Sometimes reactions just rearrange the atoms and give the same number of moles of product, sometimes they create more molecules, and sometimes they create fewer molecules.

In an ideal gas, there is a neat relationship between the number of moles and the volume or pressure (at constant pressure the volume is proportional to the number of moles of gas; at constant volume, the pressure is proportional to the number of moles of gas). So your question asks you to compare the number of moles resulting from the reaction to the number going into the reaction. since they are the same, the pressure won't change.

The balance chemical equation is defined as the total mass of reactant is exactly equal to the total mass of product.

Molar mass of Cu  is 63.57 g/mol.

Mole of Cu in 100 g

= (100 g/63.57 g/mol)

= 1.573 mol

Molar mass of AgNO3 is 169.91 g/mol.

Mole of AgNO3 in 200 g

= (200 g/169.91 g/mol)

= 1.177 mol.

From the balanced, the mole ratio of Cu to AgNO3 is 1:2.

So, for 1.573 mol of Cu, mole of AgNO3 required for reaction

= (2/1) x 1.573

= 3.146 mol.

Therefore, Cu is the excess reactant.

From the balanced equation again, the mole ratio of AgNO3 to Ag is 2:2 or simply 1:1.
