Answer:

C) differ in the arrangement of their atoms about a double bond

Explanation:

Cis-trans isomers -

Isomers are the molecules which have the same molecular formula but they differ in their arrangement of atoms.

The two isomers possible are the cis and the trans isomer .

1. Cis - isomer - The priority group or the similar group are at same side of the double bond .

2. trans - isomer -  The priority group or the similar group are at different side of the double bond . ( the group are diagonally present )

Hence , the option about cis - trans isomer is ( c ) .

From a laboratory process, a student collects 28.0 g of hydrogen and 224.0 g of oxygen. how much water was originally involved i
nikklg [1K]

Chemical reaction is given as :

2H_{2}O\rightarrow 2H_{2}+O_{2}

Here, 2 moles of water gives 2 moles of hydrogen and one mole of oxygen.

Mass of hydrogen =  28.0 g (given)

Mass of oxygen = 224.0 g (given)

Number of moles = \frac{given mass}{molar mass}

Thus, number of moles of hydrogen = \frac{28 g}{2\times 1 g/mol}

= 14 moles of hydrogen

Number of moles of oxygen= \frac{224 g}{2\times 16 g/mol}

= 7 moles of oxygen

Now, to find the amount of water:

7 mol of oxygen \times (\frac{2 mol of water}{1 mol of oxygen})\times (18 g/mol of water)

= 252 g of water.

Thus, amount of water is 252 g (involved in the process).

Who is considered the boss of the water cycle?<br><br> will mark brainliest
oee [108]

Answer: The sun

Explanation:

its the real boss of the water cycle, and it doesn't even live here on Earth. The sun provides heat, or energy, which is what makes the water cycle work. The sun's heat allows water to change forms from liquid to gas to ice and back again.

<h3>Answer:  b) 0.250 mol</h3>

============================================

Work Shown:

Using the periodic table, we see that

  • 1 mole of carbon = 12 grams
  • 1 mole of oxygen = 16 grams

These are approximations and these values are often found underneath the atomic symbol. For example, the atomic weight listed under carbon is roughly 12.011 grams. I'm rounding to 2 sig figs in those numbers listed above.

So 1 mole of CO2 is approximately 12+2*16 = 44 grams. The 2 is there since we have 2 oxygens attached to the carbon atom.

-------------------

Since 1 mole of CO2 is 44 grams, we can use that to convert from grams to moles.

11.0 grams of CO2 = (11.0 grams)*(1 mol/44 g) = (11.0/44) mol = 0.250 mol of CO2

In short,

11.0 grams of CO2 = 0.250 mol of CO2

This is approximate.

We don't need to use any of the information in the table.
