Compared to the charge of a proton, the charge of all electron has(1) a greater magnitude and the same sign
(2) a greater magnitude and the opposite sign
(3) the same magnitude and the same sign
(4) the same magnitude and the opposite sign

Answers

Answer: option (4) the same magnitude and the opposite sign.

Justification:

1) Electrons are negative particles thar are around the nucleus of the atom (in regions called orbitals).

2) Protons are positive particles that are inside the nuclus of the atom.

3) The nucleus of the atom has the same number of protons as electrons are in the orbitals of the atom.

4) The atoms are neutral (neither positive nor negative) because there are the same number of electrons and protons and their charge are of the same magnitude but different sign: (+) + (-) = 0: positive + negative = neutral.

The charge of a proton and the charge of all electron has (4) the same magnitude and the opposite sign

Further explanation

Inside the atom consists of a nucleus containing 3 basic particles namely protons and neutrons, while electrons circulate the nucleus on a particular path so that electrons are not attracted to the nucleus.

The charge of these three atomic particles is based on the Rutherford experiment. Rutherford experimented with firing alpha rays on a thin gold plate. From this experiment it was found that:

1. Most alpha rays are passed through the gold plate, so it is concluded that most of the space in the atom has empty space

2. A small number of alpha particles deflected shows there are positively charged particles inside the atom

(at this time these particles are called protons located in the atomic nucleus)

From here comes the Rutherford atomic model which states that atoms consist of positively charged particles (protons) and negatively charged electrons around the nucleus.

The charge of 1 proton is equal to a charge of 1 electron, but the sign is different.

The proton is positively charged (+1), the electron is negatively charged (-1). and neutrons not charged (neutral)

Charge of 1 electron = e = -1.66.10⁻¹⁹ coulomb

Whereas the neutron charge = 0

What happens immediately before a volcano erupts?

Answers

Well, the cause of a volcanic eruption is when the lower crust melts. This leads to the formation of magma. The volcano is an opening through which the magma is discharged. The rock inside the earth melts. This magma is diffused upwards through the volcano. If magma reaches the top of the volcano, it behaviour depends on viscosity. So what happens before a volcanic eruption is that the lower crust melts, causing the formation of magma, which is released through the volcano. Hope i helped.

Write the pressure equilibrium constant expression for this reaction. 2CO2 (g) + 4H2O (g) → 2CH3OH (l) + 3O2 (g)

Answers

Answer:

The pressure equilibrium constant (Kp) = (P O₂)³/(P CO₂)²(P H₂O)⁴.

Explanation:

For the reaction:

2CO₂ (g) + 4H₂O (g) → 2CH₃OH (l) + 3O₂ (g).

The pressure equilibrium constant (Kp) = the product of the pressure of the products side components / the product of the pressure of the reactantss side components.

each one is raised to a power equal to its coefficient.

∴ The pressure equilibrium constant (Kp) = (P O₂)³/(P CO₂)²(P H₂O)⁴.

Which of the following best describes a mixture? *two or more substances combine and cannot be separated

two or more substances combine chemically

two or more substances combine but keep their physical properties

two or more substances combine and create an irreversible reaction

Answers

Mixtures are combination of two or more substances which can be separated based on their physical properties. Hence, option c best describes a mixture.

What are mixtures?

Mixtures are substances formed by the combination of two or more individual components. The mixing can be of physical or chemical type. The individual components can be separated using some techniques based on their physical properties.

There are both homogenous mixtures and heterogenous mixtures. In homogenous mixtures the components are uniformly mixed and form a single phase.

Heterogenous mixtures are composed of components forming different phases. They can be easily separated using simple techniques. Irrespective of the type of mixing, the physical properties of the components are maintained as such in a mixture. Hence, option c is correct.
