What else can I help you with?
Are Polymers molecules made from repeating units of identical organic compounds that are linked together by hydrogen bonds?
False, they are by covalent bonds
Are Organic compounds covalently bonded and they always contain oxygen?
Organic compounds are covalently bonded molecules that contain carbon, hydrogen, and sometimes other elements like oxygen, nitrogen, sulfur, or phosphorus. Oxygen is not always present in organic compounds, but it is a common element found in many organic molecules.
Is it true or false that covalent bonds contain ions?
False. Covalent bonds involve the sharing of electrons between atoms, not the transfer of electrons to form ions.
When water boils interatomic bonds are broken.true false?
True. When water boils, the intermolecular hydrogen bonds between water molecules are broken, allowing them to escape as vapor.
Polymers are large organic molecules that are made up of?
False, polymers are molecules made from repeating units of identical or nearly identical compounds called monomers that are linked together by a series of covalent bonds.
True or false Both ionic and covalent bonds between molecules are very strong?
True. Both ionic and covalent bonds are strong chemical bonds that hold molecules together by sharing or transferring electrons between atoms. Ionic bonds result from the attraction between positively and negatively charged ions, while covalent bonds involve the sharing of electron pairs between atoms.
A substance is organic if it did not arise from materials that were once part of a living thing true of false?
False. A substance is organic if it contains carbon-hydrogen bonds, regardless of whether it originated from living or non-living sources.
The attraction between various combinations of atoms will produce bonds which form molecules. True False?
True. Atoms can form bonds with each other through the attraction between their electrons, resulting in the formation of molecules.
True or false Only DNA molecules contain the nitrogen base called uracil?
False. Uracil is a nitrogen base found in RNA molecules, not DNA. In DNA, thymine is the equivalent nitrogen base to uracil.
All compound with carbon are considered Organic compound?
Not all compounds with carbon are considered organic compounds; only compounds containing carbon-hydrogen (C-H) bonds are classified as organic compounds. Inorganic compounds may also contain carbon but lack C-H bonds, such as carbonates like CO3^2- or oxides like CO2.
True or false When sugar is dissolve in water the sugar and water are chemically combined?
False. When sugar is dissolved in water, it is a physical change where the sugar molecules are dispersed in the water but no chemical bonds are formed between them.
Is it true or false when an ionic solid mixes with water the solute breaks down into individual molecules?
False. When an ionic solid mixes with water, the solute breaks down into ions, not individual molecules. This process is known as dissociation, where the ionic bonds are broken, and the ions are surrounded by water molecules.
