A3.689 g object is added to 7.29 ml of water causing the water level to rise to 8.54 ml. what is the density of the object?

2.95 g/mL

explanation: first you find the difference between the previous and current water level:

8.54-7.29=1.25

then you place 3.689g over 1.25mL then divide:

you get 2.9512

due to significant #'s the answer is rounded and turned into:

2.95 g/mL

hoped this helped and that it's actually right-_-

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
