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

<h3>Further explanation</h3>

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

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.

Oxygen gas is collected over water. The total pressure (the O2 pressure the water vapor pressure) is 736 torr. The temperature o

tigry1 [53]

Answer:

The value of the partial pressure of the oxygen $P_{O_{2} }$ = 690 torr

Explanation:

Total pressure of the mixture of gases = 736 torr

The partial pressure of water vapor = 46 torr

From the law of pressure we know that

Total pressure = The partial pressure of water vapor + The partial pressure of oxygen $O_{2}$

Put the values of pressures in above equation we get,

⇒ 736 = 46 + $P_{O_{2} }$

⇒ $P_{O_{2} }$ = 736 - 46

⇒ $P_{O_{2} }$ = 690 torr

This is the value of the partial pressure of the oxygen.

The expression below was formed by combining different gas laws. V is proportional to StartFraction n T over P EndFraction. Whic

Ronch [10]

Answer:

The Ideal gas law

Explanation:

From the given question, we have:

V $\alpha$ $\frac{nT}{P}$

where each variable has its usual meaning.

Thus,

V = $\frac{nRT}{P}$

where R is the ideal gas constant

cross multiply to have;

PV = nRT

This implies that the volume of the gas is directly proportional to the number of moles of the gas.

Therefore, the law can be used to determine the relationship between the volume and number of moles is the ideal gas law.

which of the following describes something an engineer would probably do first when developing new technology meant to reduce oc

JulijaS [17]

Answer:

Option B. is the right answer.

Explanation:

Before developing a new technology, an engineer has to evaluate the advantages and disadvantages of the chemical used in order to clean water bodies. If the chemical has more disadvantages as compared to advantages, so its usage will be avoided while if the chemical does not harm the marine organisms of the ocean so it can be used for the purpose of cleaning. So we can say that first the engineer has to study the chemicals.

Zinc oxide adopts a face-centered cubic arrangement. Both Zinc ions and oxide ions adopt the face-centered cubic arrangement; wi

vichka [17]

Answer:

5.41 ×10⁻²²

Explanation:

We were told right from the question that both the Zinc ions and the Zinc oxide adopts a face-centered cubic arrangement.

Then, the number of ZnO molecule in one unit cell = 4

The standard molar mass of ZnO = 81.38g

Avogadro's constant = 6.023 × 10²³ mole

∴

The mass of one unit cell of zinc oxide can be calculated as:

= $\frac{4*81.38}{6.023*10^{23}}$

= 5.40461564×10⁻²²

≅ 5.41 ×10⁻²²

∴ The mass of one unit cell of zinc oxide = 5.41 ×10⁻²²
