Answer:
2.67 m
Explanation:
We can write the proportion several ways. One of them is ...
(model to Jupiter)/(Jupiter distance) = (model to Pluto)/(Pluto distance)
(model to Jupiter)/5.27 = 20 m/39.5 . . . . . fill in the numbers
(model to Jupiter) = 20 m(5.27/39.5) ≈ 2.67 m
The model of Jupiter should be placed 2.67 meters from the sun.
Nonmetals is most likely the answer
Answer:
A
Explanation:
because number of particle = moles × 6.02 × 10^23
which gives the answer as an A
Answer:- D. 1.8 moles of Fe and .
Solution:- The balanced equation is:
let's first figure out the limiting reactant using the given moles and mol ratio:
= 5.4 mol CO
From calculations, 5.4 moles of CO are required to react completely with 1.8 moles of Iron(III)oxide but only 2.7 moles of CO are available. It means CO is limiting reactant.
Products moles depends on limiting reactant. Let's calculate the moles of each reactant formed for given 2.7 moles of CO.
= 1.8 mol Fe
=
So, the correct choice is D. 1.8 moles of Fe and are formed.
