the balanced equation for the combustion of ethane is as follows
2C₂H₆ + 7O₂ --> 4CO₂ + 6H₂O
molar ratio of C₂H₆ to H₂O is 2:6
this means that when 2 mol of C₂H₆ react 6 mol of H₂O are produced
for every 1 mol of C₂H₆ that reacts thrice the number of moles of H₂O are produced
therefore when 1.4 mol of C₂H₆ reacts - 3 x 1.4 = 4.2 mol of H₂O are produced
the answer is 4.2 mol
I took this quiz and the correct answer is not A.
4Na3PO4 The 4 at the beginning of the formula is important, it means you multiply everything after it by 4 so you would instead get the answer,
D. 12 Sodium, 4 phosphorus, 16 oxygen
The choices can be found elsewhere and as follows:
<span>a.
Waxy needles
b.
Cone-shaped
c.
Thin trunks
d.
Low-growing
I think the correct answer is option D. The moss </span><span>campion adapted to enable its survival in the alpine biome by its ability of low-growing. Hope this answers the question.</span>

Answer:
The answer is
<h2>0.56 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of liquid = 0.165 g
Next we change the volume from L to mL using the conversion
1 L = 1000 mL
We have
If 1 L = 1000 mL
Then 0.000295 l = 1000 × 0.000295
volume = 0.295 mL
The density is
We have the final answer as
<h3>0.56 g/mL</h3>
Hope this helps you
