A right triangle must contain angles of measure less than 90?
Yes. In fact, it must contain TWO angles of measure less than 90 degrees.
Is it a rule that in every syllable of a word there must be a vowel?
No, but there must be a vowel sound.
How do you know which units of a conversion factor must be in the denominator?
The denominator must contain the unit that you wish to cancel in the numerator of the other number.
What do Aldehydes and ketones both contain?
Aldehydes and ketones both contain a carbonyl group, which is a carbon atom double-bonded to an oxygen atom. In aldehydes, the carbonyl group is located at the end of a carbon chain, while in ketones, it is located within the carbon chain.
Is sulfide organic?
No. Sulfide is simply a sulfur atom with a negative charge. To be organic a compound must contain carbon.
What is the carbon dioxide ratio?
It is 1 carbon atom to every two oxygen atoms. I'm no maths whizz, but if carbon dioxide is CO2, then that must be it.
Every atom of carbon must contain?
six protons and six neutrons in its nucleus. This gives carbon its atomic number of 6 and atomic mass of 12. The number of electrons in a carbon atom is also equal to its number of protons to maintain a neutral charge.
What must a neutral atom with four protons contain?
A neutral atom must contain an equal number of electrons because it is a neutral atom.
What must an organism contain?
carbon
All organic compounds must contain what element?
All organic compounds must contain the element carbon.
What does carbon dating have to do with the fossil record?
Nothing. Something must contain carbon to be carbon dated. By definition fossils are mineralized and contain no carbon.
If a carbon atom is to become the negative end of a bond which atom must it be bonded to?
If a carbon atom is to become the negative end of a bond, it must be bonded to an atom that is more electronegative than carbon. Typically, atoms like oxygen (O), nitrogen (N), and fluorine (F) are more electronegative than carbon and can form a bond where carbon carries a partial negative charge.
What must contain carbon and hydrogen?
An organic compound must contain carbon and hydrogen, but also may contain oxygen, nitrogen, sulfur, and phosphorus. An organic compound that contains only carbon and hydrogen is called a hydrocarbon.
Is 1 atom of carbon a molecule or element?
One carbon atom is an element. You must have two or more atoms to make a molecule.
What must a neutral atom with four contain?
A neutral atom with four electrons must contain four protons in the nucleus in order to maintain an overall neutral charge.
