Answer:
if you mean "measure" you can use many things. from inches to meters. sometimes if they are big they are measured in "stories". but the smaller the unit is. the harder it is and longer it takes to measure it
I believe the correct response is the first option.
Answer: B2Br6 + 6HNO3 → 2B(NO3)3 + 6BrH
Equation
B2Br6+HNO3=B(NO3)3+HBr
B=2 B=1
BR=6 BR=1
H=1 H=1
N=1 N=3
O=3 O=9
ANSWER
B2Br6 + 6HNO3 → 2B(NO3)3 + 6BrH
B=2 B=2
BR=6 BR=6
H=6 H=6
N=6 N=6
O=18 O=18

Since, we have the reaction as,
2Li(s) + F2(g) --> 2LiF(s)
we are only concerned with the limiting reactants. We calculate for the amount of product that can be produced with the given amount of reactants.
a. 1 g Li(1 mol / 6.941 g of Li)(2 mol LiF/2 mol Li) = 0.144 mol LiF2
1 g F2(1 mol/38 g)(2 mol LiF2/1 mol F2) = 0.052 mol LiF2
Answer: 1 g of F2
b. 10.5 g Li(1 mol/6.941 g of Li)(2 mol LiF/2 mol Li) = 1.512 mol LiF2
37.2 g F2(1 mol/38 g)(2 mol LiF2/1 mol F2) = 1.958 mol LiF2
Answer: 10.5 g of Li
c. (2.85 x 10^3 g Li)(1 mol/6.941 g of Li)(2 mol LiF/2 mol Li) = 410.60 mol LiF2
(6.79 x 10^3 g F2)(1 mol/38 g)(2 mol LiF2/1 mol F2) = 357.368 mol of LiF2
Answer: 6.79 x 10^3 g F2
Explanation:
Sand is a common material found on beaches, deserts, stream banks, and other landscapes worldwide. In the mind of most people, sand is a white or tan, fine-grained, granular material. However, sand is much more diverse - even beyond the pink sand beaches of Bermuda or the black sand beaches of Hawaii.
