A molecule always has three types of elements present
b.
Compounds always include the elements hydrogen and sodium
c.
Compounds include things we use in our everyday lives
d.
All elements prefer to hang out with other elements and form molecules
Answers
The true statement among the following options is c. As the substances which we use are compounds.
Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.
Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.
Compounds include things we use in our everyday lives.Compounds are substances composed of two or more different elements chemically combined in a fixed ratio by weight. They are everywhere in our daily life, from food to electronics. For example, table salt is a compound that we use to enhance the flavor of our food.
Thus, the correct option is C.

149g/mol is the gram-formula mass of (NH)
PO
. Therefore, the correct option is option C.
The quantity of a compound which has the exact same mass in grammes that its formula mass in an atomic mass unit is said to have the compound's gramme formula mass. Each atom of every component has a distinctive mass, and every molecular unit of a compound possesses a distinctive mass determined by the complex's formula. It is referred to as the Gramme Formula Mass because the formula-determined mass of a substance that is ionic is calculated by adding the atomic masses of each of its constituents. Gram-formula mass of (NH)
PO
= (14+4)×3+31+16×4= 149g/mol
Therefore, the correct option is option C.

Answer:
1. Considering the massive size of the structures, it is improbable to think that man is actually capable of building them.
2. And the intelligence and calculations needed for this construction is beyond the capacity of man, considering the age and times of the ancient Egyptians.
Explanation:
While Egyptologists and historians have, through years and years of research, have found evidence that it was actually the Egyptians that built them, there are also some people who held the belief that they are actually made and constructed by aliens. The humans of the ancient time that these structures were constructed were incapable of having the intelligent power and manpower and strength to carry out these works, with big blocks of stones and massive heavy structures to be made. However, the article "Who Built The Pyramids" shows the findings of Egyptologists Mark Lehner and Zahi Hawass who has worked to uncover the truth about these massive buildings of ancient years, trying to prove who actually built and how. They argued that, with all the workforce needed to actually bring about the construction of these structures, it is evident that the people of Egypt indeed were the workers and builders of these structures, and that too not as slaves (unlike many claims) but more as a sense of obligation to the king. And to refute the alien builder theory, there are definite proof that shows that it is humans and not aliens who built it. There are settlements that housed the workers, bone remains that have been examined by scientists and doctors, who have proved that humans and not aliens are the workers. Added to it, there seem to be no findings or even a shred of evidence too prove aliens have indeed been there, let alone construct that. Considering the massive structure of the pyramids, it is probable to think that man is incapable of constructing something like these, but like Lehner and Hawass has pointed out, there are lots of evidences to prove man actually built them. But there are still other group of theorists and believers that thinks aliens and not humans built them.
Answer:
Those who support the alien theory believe that the ancient Egyptians were very primitive. They argue that no blueprints of the pyramids have been found and that moving two-ton stones would have required alien technology.
