A rectangular solid measures 1.0m by 5.6cm by 2.1mm express its volume in cubic meters
Answers
1.0m=1.0m
5.6cm=0.056m
2.1mm=0.0021m
Then, you just want to multiply the three together to get the total volume.
1.0X0.056X0.0021=0.0001176 or 0.00012, if your teacher wants you to use proper sig figs
Answer : The volume of of rectangle is,
Explanation : Given,
Length of rectangular solid = 1.0 m
Width of rectangular solid = 5.6 cm = 0.056 m
conversion used : (1 cm = 0.01 m)
Height of rectangular solid = 2.1 mm = 0.0021 m
conversion used : (1 mm = 0.001 m)
Formula for volume of rectangle :
where,
V = volume of rectangular solid
l = length of rectangular solid
b = width of rectangular solid
h = height of rectangular solid
Now put all the given values in the above formula, we get:
Therefore, the volume of of rectangle is,

What is hydrocarbon?
Any member of a group of organic compounds comprised only of the atoms carbon (C) as well as hydrogen (H) (H). The carbon atoms bind together to create the compound's framework, as well as the hydrogen atoms connect to them in a variety of ways.
Petroleum as well as natural gas are mostly composed of hydrocarbons. They are used as fuels and lubricants, as well as raw materials to make polymers, fibers, rubbers, solvents, explosives, various industrial chemicals. The name of the hydrocarbon CH(CH

Answer is: n-octane.
Octane is the straight-chain alkane (an acyclic saturated hydrocarbon) with eight carbon atoms.
Carbons in octane have sp3 hybridization (carbon’s 2s and three 2p orbitals combine into four identical sp3 orbitals).
Orbitals in sp3 hybridization have a tetrahedral arrangement and form single (sigma) bonds.
Burning octane fuel is very fast chemical reaction, it happens in immediately.
Main products of the combustion of fossil fuels are carbon(IV) oxide and water.
Chemical reaction: C₈H₁₈ + 25/2O₂ → 8CO₂ + 9H₂O; ΔH = -5500 kJ/mol.

Answer:
When an electron is hit by a photon of light, it absorbs the quanta of energy the photon was carrying and moves to a higher energy state. This higher energy state is to imagine that the electron is now moving faster, (it has just been "hit" by a rapidly moving photon) Electrons therefore have to jump around within the atom as they either gain or lose energy
Explanation:
They gain or lose energy.

By breaking a carbon double bond and adding chlorine.
By removing hydrogen because of chlorine’s attraction to hydrogen’s nucleus.
Chlorine and ethene do not react spontaneously.
Answers
Explanation : When chlorine reacts with ethene it forms dicholoroethane. It reacts spontaneously to form product. The halogenation reaction takes place in ethene across the double bonds and removes the hydrogen from ethene and two chlorine atoms gets attached in their place; which results in dichloroethane as the product.
Answer: option B m
Explanation:
It is an example for Electrophilic Addition of Halogen. And addition of Cl2 to Alkene is always Trans Addition. That means both cl atoms should add opposite side of double bond and results vicinal 1,2-dichloroethane as a product.

B. nitrogen (N), bismuth (Bi), antimony (Sb)
C. antimony (Sb), nitrogen (N), bismuth (Bi)
D. bismuth (Bi), antimony (Sb), nitrogen (N)
Answers
Answer: Option (A) is the correct answer.
Explanation:
Nitrogen is a non-metal and it is known that non-metals do not conduct electricity. Thus, it will be least conductive out of the given options.
Whereas antimony (Sb) is a metalloid. Metalloid are the substance that show properties of both metals and non-metals. Thus, antimony will conduct electricity.
On the other hand, bismuth (Bi) is a metal hence, it will conduct electricity.
Thus, we can conclude that the order from least conductive to most conductive will be nitrogen (N), antimony (Sb), bismuth (Bi).
Answer: The correct answer is Option A.
Explanation:
Conductivity of an element is defined as the tendency to conduct electricity. This property is shown mostly by metals and then by some metalloids and least by non-metals.
Metals are defined as the elements which loose electrons easily and thus can easily conduct electricity due to the presence of free electrons.
Metalloids are defined as the elements which show the properties of both metals and non-metals. Some metalloids are conductive, some are not.
Non-metals are defined as the elements which gain electrons easily and thus cannot conduct electricity easily and are considered as non-conductive.
From the given options:
All the three elements belong to same group but nitrogen is a non-metal, antimony is a metalloid and Bismuth is a metal.
Thus, the order of conductivity follows:
Hence, the correct answer is Option A.
