Answer : The correct option is, (1) Gains an electron and its radius increases.

Explanation :

The given element is chlorine.

Atomic number of chlorine = '17'

The electronic configuration of chlorine is, $1s^22s^22p^63s^23p^5$

Number of electrons = 17

Number of protons = 17

The electronic configuration of chloride ion is, $1s^22s^22p^63s^23p^6$

Number of electrons = 18

Number of protons = 17

When the chlorine atom gains an electron to acquire a stable electronic configuration. As the electrons add in the valence shell of the chlorine, the number of electrons increases but the number of protons remains the same. So, the protons will not be able to bind the extra electron and it will remain far from the nucleus.

As a chlorine atom becomes a negative ion, the atom (1.) gains an electron and its radius increases. The chlorine atom gains an electron (which is a negatively charged ion) in order to become a chloride and to fulfill the outer shell.

For the following reaction, 2.45 grams of methane (CH4) are allowed to react with 27.7 grams of carbon tetrachloride . methane (

rosijanka [135]

Answer:

The limiting reactant is CH₄

26.0g of CH₂Cl₂ is the maximum amount that can be formed

4.15g CCl₄ will remain

Explanation:

The reaction of methane, CH₄, with carbon tetrachloride, CCl₄ is:

CH₄ + CCl₄ → 2CH₂Cl₂

To find the maximum mass of dichloromethane that can be determined we need to find moles of methane and carbon tetrachloride:

Moles CH₄:

2.45g * (1mol / 16.04g) = 0.153 moles

Moles CCl₄:

27.7g * (1mol / 153.82g) = 0.180 moles

That means just 0.153 moles of CCl₄ will react until CH₄ is over.

The limiting reactant is CH₄

Assuming the whole 0.153 moles will react, the moles of CH₂Cl₂ will be:

0.153 moles CH₄ * (2 moles CH₂Cl₂ / 1 mole CH₄) = 0.306 moles of CH₂Cl₂

The mass is (Molar mass dichloromethane: 84.93g/mol):

0.306 moles of CH₂Cl₂ * (84.93g / mol) = 26.0g of CH₂Cl₂

The moles of CCl₄ that remain are:

0.180 moles - 0.153 moles = 0.027 moles

In grams:

0.027 moles * (153.82g / mol) = 4.15g CCl₄

Write a hypothesis about whether radiation has the same impacts on coastal areas, forest areas, and desert areas.

Natasha2012 [34]

Radiation has different intensity of impact depending on the area which they are experienced. Excessive amounts of radiation cause abnormalities in the growth of living things, humans, animals, and plants. The intensity of the damage in forest and coastal areas is higher compared to desert areas since more wildlife are present in the two former areas.

Oksanka [162]

Answer:

Answer B

Explanation:

By definition mixtures are combinations of substances physically prepared and physically separated. Mixtures are classified as 'homogeneous mixtures' and 'heterogeneous mixtures'. For homogeneous mixtures all components are dissolved, with solute evenly distributed throughout the solution and assumes state of solvent. 'Heterogeneous mixtures' have inconsistent properties throughout and solute concentration is not consistent throughout the mixture.

Which of the following describes the characteristics of a plasma? (3 points) a Particles are packed closely together, have low c

Jobisdone [24]

Answer:

The correct option is;

b. The particles are positively and negatively charged, have high compressibility, and spread out to fill a container

Explanation:

Plasma are gases that contain positively and negatively charged particles. Therefore, plasma flow drift in space such that plasma. like gases has no characteristic shape or volume but takes the shape and fills the entire volume of a container in which it is placed

Other characteristics of plasma are that plasma is a conductor of electricity and magnetic fields can therefore exist in plasma due to the fact that plasma are made of atoms in which part or all of the electrons have been removed leaving the ions to roam freely in a container.
