A) The alcohol in "gasoholburns according to the following equation: C 2 H 6 O+3O 2=2 CO 2 +3H 2 O . In a test, 9.56 moles of water is collected from this reaction How many moles of CO 2 also formed ? B) Use the following equation to answer the question below. Fe 2 O 3 + 3 H 2=2 Fe + 3 H 2 O How many moles of iron are made from 22.82 moles of Fe 2 O 3 ?

C) How many moles of H 2 SO 4 will react with 471.75 g of NaOH? 2 NaOH + H 2 SO 4=Na 2 SO 4 + 2H 2 O

Iwould you figure it out but you don't have a picture or in your question as to what the physical property you're looking for is

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant. 

Idon't know hope someone you
