Which is a characteristic of the polar water molecule?
a tetrahedral electron domain geometry with covalently bonded atoms
a tetrahedral electron domain geometry with ionically bonded atoms
a linear shape with polar covalent bonds
a linear shape with polar ionic bonds

a tetrahedral electron domain geometry with covalently bonded atoms

Explanation:

Water molecule has one central oxygen (with two lone pairs) and with two hydrogens (one on each side). Oxygen is more electronegative hence pulls electrons towards it making it partial negative and the hydrogen partial positives. Since Oxygen has four domains around it (1 domain counts for each lone pair or bond) This is a characteristic of a tetrahedral electron domain geometry with covalently bonded atoms

polar ionic would be where electrons are completely transferred but in case of water, the electrons are not completely transferred from hydrogen to oxygen rather electrons spend most time around oxygen but are still shared b/w oxygen and hydrogen

the answer for apex is "1 and 6"

weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall

erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.

here's your answer.
