Why are microwaves idea for transmitting satellite communication signals?
Answers
Answer:
Microwaves are best suited because
they have a higher frequency and small wavelength
Satellite communication and Earth observation from space benefit from microwaves that can pass through haze, light rain, snow, clouds, and smoke. Because they can penetrate the atmosphere, microwaves are used. Small wavelength and high frequency is employed for this.
Microwaves are radio waves with short wavelengths and frequencies in the gigahertz (GHz) range. They can send signals over great distances without any data loss thanks to their high frequency. Without producing signal overlap or interference, they may carry a wide range of frequencies.
Electromagnetic radiations include radio waves and microwaves. In communication, both are utilized. Television and radio programs are transmitted by radio waves, but mobile phones and Wi-Fi use microwaves. Radio waves are one of the several alternatives for satellite communication.

Each of these Ionic Compounds are named INCORRECTLY. 1. Find and describe the mistake 2. Correctly name the compound. CaCl2 - Calcium Chlorine CuS - Copper Sulfide Li3P - Trilithium Phosphide CuBr - Copper(II) Bromide NaOH - Sodium Hydrogen Oxide
Answers
Explanation:
The nomenclature of ionic compounds is given by:
1. Positive is written first. And if the metal atom has various oxidation states then its oxidation state is to be mentioned in brackets with help of roman numbers
2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
1.) : Calcium chloride (Correct)
In the given compound, calcium has oxidation state of +2 and chlorine has oxidation state of -1.The name is correct.
2.) : Copper (II) oxide (Incorrect)
In the given compound,copper has the oxidation state of +1 and oxygen has oxidation state of -2.So ,the correct name will be Copper (I) oxide.
3.) : Lead (II) sulfide (Incorrect)
In the given compound, lead has the oxidation state of +4 and sulfur has oxidation state of -2. So ,the correct name will be Lead (IV) sulfide.

Answers
Answer:
Elements in the same group has different physical properties such as boiling and melting points. However there are trends of their physical properties down the group.
Explanation:
You should look at the perdoic table to for extra help
The boiling points and melting points of the given elements does not support the claim that elements of the same group have similar physical properties.
What are boiling point and melting point?The boiling point of a substance is the temperature at which it changes from liquid state to gaseous state. Melting point is the temperature at which the substance changes from solid to liquid state.
Elements in the same group shows similar physical and chemical properties. But from the boiling and melting point we cant say that they are in the same group.
Elements in a group shows a trend in boiling point and melting point but cannot be distinguished with this from other groups.
Hence, boiling point and melting point of the elements do no support for the similar properties in a group.

what is the molarity of an hcl solution if 50.0 ml is neutralized in a titration by 40.0 ml of 0.400 m naoh? group of answer choices 0.200 m 0.280 m 0.320 m 0.500 m
Answers
The molarity of an HCl solution if 50.0 ml is neutralized in a titration by 40.0 ml of 0.400M NaOH is 0.320 M.
HOW TO CALCULATE MOLARITY:
The Molarity of an acid when involved in a titration procedure can be calculated by using the formula below:M1V1 = M2V2
Where;
M1 = molarity of acid (M)M2 = molarity of base (M)V1 = volume of acid (mL)V2 = volume of base (mL)According to this question,
M1 = ?M2 = 0.400MV1 = 50 mLV2 = 40 mLM1 × 50 = 0.400 × 40
50M1 = 16
M1 = 16 ÷ 50
M1 = 0.32M
Therefore, the molarity of an HCl solution if 50.0 ml is neutralized in a titration by 40.0 ml of 0.400M NaOH is 0.32 M.Learn more at: https://brainly.com/question/8732513?referrer=searchResults

which group of the periodic table is composed of inert gases
Answers
Answer:
Group 0
Explanation:
A cheerful teen willing to help,

The group zero of the periodic table is composed of inert gases.They are very unreactive So, they don't form molecules easily and are found as single atoms.
Which group of metals is inert?"Noble metals, such as gold, platinum, silver, and a few rare metals. Members of this class have little or no tendency to unite with oxygen in the free state and do not change composition when placed in water at a red heat.
Noble gas atoms already have complete outer shells and have no tendency to lose, gain, or share electrons. As a result, noble gases are inert and do not participate in chemical reactions.
Because their outermost shells are completely filled, zero group elements are inert. They have no tendency to lose, gain, or share electrons with other elements.
Thus, The group zero of the periodic table is composed of inert gases because they are unreactive.

when is it appropriate to form double or triple bonds in a lewis structure?
Answers
It is appropriate to form double or triple bonds in a Lewis structure when four or six electrons are shared.
A Lewis structure is a representation of a molecule using dots to show the valence electrons in the molecule. This dots are shown around the symbols of the elements.
However, in instances where four or six electrons are shared between bonding atoms, a double or triple bond is used. A double bond means that four electrons are shared. A triple bond means that six electrons are shared.
