What is 5 5 5 5 5 equals 26?
It is a FALSE statement.It is a FALSE statement.It is a FALSE statement.It is a FALSE statement.
Are proteins composed of subunits called fatty acids and glycerol made up of carbon hydrogen and oxygen?
That statement is false.
True or false water is an example of a chemical element?
False. Water is a molecule made of 2 parts hydrogen one part oxygen. NOT AN ELEMENT.
True or false if 25 g of hydrogen is mixed with 25 g of oxygen 50 g of water is formed?
False.
True or false Hydrogen and oxygen atoms have an equal number of electrons?
False. Hydrogen atoms have one electron, while oxygen atoms have eight electrons.
True or false Water is an example of a polar molecule?
True. Water is a polar molecule because it has a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom due to differences in electronegativity. This polarity allows water to form hydrogen bonds with other water molecules.
Diamond and quartz are both minerals composed of a single element true or false?
False. Diamond and quartz are minerals composed of multiple elements. Diamond is composed of carbon atoms, while quartz is composed of silicon and oxygen atoms.
Is it true that in a water molecule the electrons within the molecule are attracted more towards the hydrogen atoms?
Yes, in a water molecule, the electrons are more attracted to the oxygen atom than the hydrogen atoms. This creates a partial negative charge on the oxygen and partial positive charges on the hydrogen atoms, leading to a polar molecule.
Water particles are not actually water molecules trues or false?
False. Water particles, whether in liquid or vapor form, are made up of water molecules consisting of two hydrogen atoms bonded to one oxygen atom.
State true or false Hydrogen is insoluble in water?
False False False FalseFalse
Is it True or False that water consists of an atom of oxygen that has formed a covalent bond with two atoms of hydrogen?
True. Water consists of one oxygen atom that has formed covalent bonds with two hydrogen atoms, resulting in the chemical formula H2O.
Is this true or false oxygen is the most prevalent gas?
False. Hydrogen is the most common gas in the universe.
Is star is born when helium and oxygen combine true or false?
False. A star is born when hydrogen starts to fuse into helium.
