You are on an alien planet where the names for substances and the units of measures are very unfamiliar. nonetheless, you obtain 87 quibs of a substance called skvarnick. you can trade this skvarnick for gold coins, but the vendors all measure skvarnick in units of sleps; not quibs. 9 quibs is equal to 8 sleps. if you have 87 quibs of skvarnick, how many sleps do you have? round your answer to the nearest tenth (one decimal place). your

-

77.3 sleps of skvarnick.

In the above question we are told that 9 quibs is equal to 8 sleps.

In the above question we are also told that we have 87 quibs of skvarnick.

Thus 87 quibs of skvarnick = x 8 sleps of skvarnick

                     = 77.333 sleps of skvarnick

                     = 77.3 sleps of skvarnick, rounded off to the nearest tenth (one decimal place).

the correct answer is answer a. a mixture

no other options make sense

hope this

have a great day : )

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8
