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.
Is water a nonpolar molecule?
No, water is a polar molecule. It has a bent shape with an unequal distribution of electrons between the oxygen and hydrogen atoms, resulting in a slight negative charge on the oxygen atom and slight positive charges on the hydrogen atoms.
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.
When iron rusts iron atoms are destroyed true or false?
False. When iron rusts, iron atoms are not destroyed. Instead, iron atoms combine with oxygen in the presence of water to form iron oxide (rust), which causes the iron to corrode.
True or false a mole of water in chemistry contains the same number of atoms as a mole of methane?
False, They contain the same number of molecules, not the same number of atoms. H2O contains 3 atoms, so in 1 mole of water there are 6.022*10^23 * 3 = 1.81*10^24 atoms. CH4 contains 5 atoms, so in 1 mole of methane there are 6.022*10^23 * 5 =3.01*10^24 atoms.
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.
Ozone is a form of oxygen true or false?
It is true. Ozone is an allotrope of oxygen.
True or false Hydrogen and oxygen atoms have an equal number of electrons?
False, a Hydrogen has 1 electron and Oxygen has 8 electrons
In the water molecule within the molecule are attracted more toward the hydrogen atoms?
false
True or false the basic unit of matter is a molecule?
False. The basic unit of matter is an atom, not a molecule. Atoms are the smallest unit of a chemical element, while molecules are made up of two or more atoms bonded together.
What regarding the carbon atoms in a molecule and its functional groups is false?
One false statement could be that all carbon atoms in a molecule must be part of a functional group. This is incorrect, as some carbon atoms may simply be part of the molecule's backbone without participating in a specific functional group.
Each hemoglobin molecule is able to transport molecules of oxygen.?
False. The mammalian hemoglobin molecule can bind (carry) up to four oxygen molecules.
Is water a nonpolar molecule?
No, water is a polar molecule. It has a bent shape with an unequal distribution of electrons between the oxygen and hydrogen atoms, resulting in a slight negative charge on the oxygen atom and slight positive charges on the hydrogen atoms.
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.
The complete breakdown of a glucose molecule during oxidative respiration requires six oxygen molecules is that true or false?
False. The complete breakdown of a glucose molecule during oxidative respiration actually requires six molecules of oxygen.
When iron rusts iron atoms are destroyed true or false?
False. When iron rusts, iron atoms are not destroyed. Instead, iron atoms combine with oxygen in the presence of water to form iron oxide (rust), which causes the iron to corrode.
Atoms are made up of tiny particles called molecules true or false?
FALSE. It is in fact the other way around. A molecule consists of two atoms or more kept together by chemical bonds.
