Can anyone ? i was absent and idk what the answers are

Scientific notation is important because astronomers and other scientist use this when they are working with very large or very small numbers. You already know that scientific notation is a system for writing and working with numbers that makes it much easier to deal with numbers that are very small or very large.

1. Scientific Notation expresses a value as the product of a number between 1 and 10 and a power of ten.

2. D

3. it makes very large or very small numbers easier to work with.

4. B and D

5. False

Hope these are correct :) Have a great day

one would be wind another would be water density

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
