Fredrick is doing a lab on ph. he uses many household items to determine the ph of his items. which of his actions best describes inappropriate lab safety?
he changes into closed-toed shoes before lab starts.
he doesn’t wear goggles because he is using household chemicals.
he asks his teacher if he can mix high- and low-ph solutions before discarding them.
he leaves his workstation to identify all of the safety equipment in the lab.

cuz he's blad

explanation:

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.
