Moles= number of molecules/Avogadro’s constant
(3.8 x 10^24) /(6.02 x 10^23)
=6.31229..
Volume=moles*24(molar gas volume under STP)
= 6.31229...*24
= 151.5 dm^3 (units mainly used in the UK)
=. 151.5 litres
Answer:
1. an educated guess
2. data
3. what changes in experiment
4. what stays the same in both groups
5. the group where nothing changes, normal
6. group with independent variable, what's being tested
Answer:
18moles of H20
Explanation:
C5H12 + 8O2 —> 5CO2 + 6H2O
From the balanced equation,
1mole of C5H12 were consumed to produce 6moles of H2O.
Therefore, if 3 moles of C5H12 were consumed, it will produce = 3 x 6 = 18moles of H20
I think the correct answer from the choices listed above is option D. the substances cobalt and barium chloride will not react since cobalt os less active than barium so it does not have enough energy to displace barium in the compound. Hope this answers the question.
