How many moles of oxygen gas react to yield 0.200 mole water? . . C5H12(g) + 8 O2(g) = 5 CO2(g) + 6H2O(g)

1 answer:

4 0

C5H12(g) + 8 O2(g) = 5 CO2(g) + 6H2O(g)
molar ratio of H2O to O = 6:8
<span>we have 0.200 moles of H2O so we need 0.200 * 8/6 moles of O2 = 0.267 moles of O2

Therefore, there will be 0.267 moles of O2 gas required to yield 0.2 moles of H20.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

CuSO4.5H2O(k) ısı CuSO4(k) + 5 H2O(g) eşitliğine göre bakır sülfatın kristal suyu miktarı ve kaba formülü hesaplanacaktır.

baherus [9]

Answer:

159.609 g/mol

Explanation:

According to the CuSO4.5H2O (k) heat CuSO4 (k) + 5 H2O (g) equation, the crystal water amount of copper sulfate and its rough formula will be calculated.

Weight of copper sulfate containing crystal water = m1 = 249.62… g

Weight of copper sulfate without crystal water weighed = m2 = 159.62 g

Accordingly, calculate the x and y values in the molecular formula of copper sulfate (xCuSO4.yH2O).

A student calculates that the volume of his textbook is 991.880 cm3. what is the volume written with 3 significant figures?

k0ka [10]

The volume of the textbook calculated by the student written to 3 significant figures is 992cm³

According to this question, a student calculates the volume of his textbook and arrived at an answer of 991.880 cm³.

To round up this digit to 3 significant figures, which means that only 3 significant numbers should appear in the answer.

To do this, the number after the third number is 8, which means we can round up the value of 1 to 2. Hence, the volume of the textbook calculated by the student is 992cm³ in 3 s.f.
