Water molecules are formed by covalent bonding. What effect does this have on
the water molecule?
creates a polar molecule with two positive
ends
creates a nonpolar molecule with two positive
ends
creates a nonpolar molecule with one positive
and one negative end
creates a polar molecule with one positive
and one negative end

When covalent compounds dissolve in water, they break apart into molecules, but not individual atoms. Water is a polar solvent, but covalent compounds are usually nonpolar. This means covalent compounds typically don't dissolve in water, instead, it makes a separate layer on the water's surface.

Explanation:

I don't understand the second part but hope this helps.

the force required to move the cart is divided by three or 33.33 n.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
