On analysis a compound was found to contain 41.55 g of element W and 8.45g of element Z. If the relative atomic mass of W is 23 and of Z is 14 the
empirical formula of the compound is​

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

i believe the answer is three water molecules

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
