Me. i am a little stuck on what to do. it's been a few months since i have balanced equations, and i know that is one of the steps. i'm very confused on what to do, will someone me?

in the following balanced neutralization reaction equation, how many moles of ca(oh)2 are required to completely neutralize 1.2 moles of hi? 2hi + ca(oh)2 → cai2 + 2h2o a) 1.2 moles b) 0.6 moles c) 2.4 moles d) 1.0 mol

Adozen is 12, and your needing to calculate the weight of one medium egg, so i would do 21/12=1.75 per egg, and check your answer by doing 1.75 * 12= 21 : ) : ): ): ): ) i hoped i

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.
