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.


Is combining hydrogen and oxygen to make it water is a physical change Is it true or false?

False. Combining hydrogen and oxygen to form water is a chemical change, not a physical change. During this process, the hydrogen and oxygen atoms chemically react to create new substances, resulting in the formation of water molecules. This transformation involves breaking and forming bonds, which is characteristic of chemical changes.


True or false Hydrogen and oxygen atoms have an equal number of electrons?

False, a Hydrogen has 1 electron and Oxygen has 8 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.


Is it true that in a water molecule the electrons within the molecule are attracted more towards the hydrogen atoms?

Water is a polar molecule where the electrons spend more time in orbitals around the oxygen atom because it is significantly more electronegative than the hydrogen atoms. So, false is the answer.


When an electric current passes through water it causes the water to start to combust true or false?

False. When an electric current passes through water, it typically causes electrolysis, which splits water molecules into hydrogen and oxygen gases rather than causing combustion. However, if the hydrogen gas produced is ignited in the presence of oxygen, it can combust, but the current itself does not cause the water to combust directly.


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.


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.
