A student is conducting a lab that requires 2 M HCl. In the chemical closet, there is 150 mL of 8 M HCl. How much water must be added to stock solution to get the desired molarity for the lab? A) 150 mL B) 450 mL C) 600 mL D) 1200 mL

I think its B-450 ml

Explanation: you have 8 and need 2 so thats 2 over 8 or 1 over 4, we have 150 ml of 8 so doing a fraction version with ml should work 150 over 450 simplified is 1 over 4 thus theres the answer

plus took the test and it was right sorry if my explamation is confusing

chemists can use the electron cloud model to assign electrons to different atomic orbitals. atomic orbitals also explain the patterns in the periodic table

explanation:

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)
