Answer:

Magnetism surrounding the wire draws the needle toward the wire.

Explanation:

Magnetism is a force which is responsible for the attraction and repulsion of objects. Magnetism is also generated around the wire in which current is flowing. This magnetism is stronger when more current flows through the wire.  This magnetism is stronger than the magnetism of the poles so when the compass brought near to the electric wire, the needle moves toward the wire.

Answer:

D.  -Magnetism surrounding the wire draws the needle toward the wire.

Explanation:

We can see that an atom with 14 protons, 14 neutrons, and 16 electrons is unstable, and has a -2 charge.

So the correct option is the third one.

An atom with 14 protons, 14 neutrons, and 16 electrons is not stable. The number of protons in an atom, also known as its atomic number, determines its element and its chemical properties. In this case, the atom has 14 protons, which corresponds to the element silicon (Si) on the periodic table.

For an atom to be stable, it should have a balanced number of protons and electrons. Electrons are negatively charged particles that orbit the nucleus of an atom in energy levels or electron shells. The number of electrons in a stable atom should be equal to the number of protons, resulting in a neutral charge overall.

In this case, the atom has 14 protons and 16 electrons, which means it has two more electrons than protons, resulting in a net charge of -2. This is an example of an ion.

Answer:

Explanation:

To find the number of moles we must first find the molar mass of LiCL

From the question

mass = 0.550g

M(Li) = 6 Cl = 35.5

Molar mass of LiCL = 6 + 35.5 = 41.5 g/mol

Then we use the formula

\(n = \frac{m}{M} \)

where

n is the number of miles

m is the mass

M is the molar mass

So we have

\(n = \frac{0.550}{41.5} \)

We have the final answer as

Because it is a chemical compound composed of manganese and bromine

Answer: Neutral Xe atom

Answer:

\(F>C> H_e\)

Explanation:

From the question we are given

a. He

b. C

c. F

Generally

The electron affinity  of an atom or molecule is defined as the amount of energy released when an electron is attached to a neutral atom or molecule in the gaseous state to form a negative ion.

Therefore

The order of electron Affinity is give as

\(F>C> H_e\)

Elements arranged according to increasing electron affinity is He, C, F.

Electron affinity is a measure of the ability of an atom or molecule to attract and accept an electron. It quantifies the energy change that occurs when an electron is added to a neutral atom or ion in the gaseous state.

When an atom or ion gains an electron, it undergoes a process called electron attachment or electron capture. The electron affinity is the energy released or absorbed in this process. A higher electron affinity value indicates a stronger attraction for electrons.

The electron affinity is typically expressed in units of energy, such as electron volts (eV) or kilojoules per mole (kJ/mol). It can be either positive or negative. A positive electron affinity indicates that energy is released when an electron is added, while a negative electron affinity indicates that energy is required to add an electron.

Na is for sodium and SO4 is sulfate...

Answer: The chemical compound name for Na₂SO₄ is Sodium Sulfate.

Answer: 75° C for mercury, 40.59° C for iron

Explanation:

the equation used to solve this problem is q=mcΔT ( where q is heat in joules, m is mass in grams, c is the specific heat capacity, and ΔT is the change in temperature in degrees celsius)

For mercury:

q = mcΔT

1050J = (150g)(0.140J/g°C)(final T - 25°C)

\(\frac{1050}{(150)(0.140)}\) = final T - 25

Final T = \(\frac{1050}{(150)(0.140)}\) - 25

Final T = 75°C

For iron:

q = mcΔT

1050J = (150g)(0.449J/g°C)(final T - 25°C)

\(\frac{1050}{(150)(0.449)}\) = final T - 25°C

final T = \(\frac{1050}{(150)(0.449)}\) + 25

Final T = 40.59°C

If heat is going into the system, then energy must have come out from the surroundings.

If heat is entering a system, it means that the system is gaining thermal energy, which can lead to an increase in temperature, changes in state, or other effects depending on the nature of the system and the heat transfer mechanism.

The first law of thermodynamics, also known as the law of conservation of energy, states that the total amount of energy in a closed system remains constant, and energy can neither be created nor destroyed, only transferred or converted from one form to another.

When heat enters a system, it is either used to increase the internal energy of the system or to perform work, such as moving a piston or driving an electrical generator.

The amount of heat transferred to a system can be quantified using the equation Q = mcΔT, where Q is the heat transferred, m is the mass of the substance, c is its specific heat capacity, and ΔT is the change in temperature.

Therefore, if the system is gaining energy in the form of heat, then the surroundings (the rest of the universe) must be losing that same amount of energy. This is because energy is conserved.

The two chemical compounds are not the same, because their ratio is not equal. In both samples the composition of lead and oxygen is different.

A chemical compound is a substance made of numerous similar molecules (or molecular entities) joined by chemical bonds and comprising atoms from various chemical elements. Therefore, a molecule made up of only one type of atom is not a compound. Chemical reactions, which may entail interactions with other molecules, can change a compound into a distinct substance. Atomic bonds may be broken or new ones created during this process.

sample 1 = mass of lead / mass of oxygen = 12.92g/2g = 6.46 .

sample 2 = mass of lead/ mass of oxygen = 34.27 - 14.39/14.39 = 1.38 .

so, the ratios are not the same.

Hence, the two chemical compounds are not the same, because their ratio is not equal. In both samples the composition of lead and oxygen is different.

The volume of a substance at STP for one mole is 22.4 L. The volume of oxygen required to react with excess of carbon sulphide to produce 4 L of carbon dioxide 4.0 L is 12 L.

Volume of a substance is the space occupied by the particles of the substance. As the temperature increase, volume also increases. The volume of one mole of every substance at standard temperature and pressure is 22.41 L

According the balanced reaction given, 3 moles of O₂ is required to produce one mole carbon dioxide. One mole of O₂ is 22.4 L. Thus volume of 3 moles of oxygen is calculated as follows:

Volume of O₂= 3×22.41 =67.2 L.

Thus, 67.2 L of O₂ produces one mole or 22.4 L of carbon dioxide.

The volume O₂ required to produce 4 L of carbon dioxide is calculated as follows:

Volume of O₂ = (67.2 L × 4 L) / 22.41 L

                       = 12 L.

Therefore, the volume of oxygen molecule required to produce 4 L of carbon dioxide on the reaction with excess of carbon sulphide is 12 L.
