Well because the lowest possibility of having a decen is 3-decene so 6-decene is not possible. Hope this helps!! :)

What mass of H₂ is needed to react with 8.75 g of O₂ according to the following equation: O2(g) + H2(g) → H₂O(g)?

FromTheMoon [43]

Explanation:

For reacting with 8.75 grams of oxygen, 1.08 grams of hydrogen is required.

The given balanced equation has been:

\rm O_2\;+\;2\;H_2\;\rightarrow\;H_2OO2+2H2→H2O

From the equation, 1 mole of oxygen reacts with 2 mole of hydrogen to give 1 mole of water.

The mass of oxygen has been: 8.75 g,

Moles = \rm \dfrac{weight}{molecular\;weight}molecularweightweight

Moles of oxygen = \rm \dfrac{8.75}{32}328.75

Moles of oxygen = 0.27 mol

Since,

1 mole Oxygen = 2 mole hydrogen

0.21 mol oxygen = 0.54 mol hydrogen

Mass of hydrogen = moles \times× molecular weight

Mass of hydrogen = 0.54 \times× 2

Mass of hydrogen = 1.08 grams.

Thus, for reacting with 8.75 grams of oxygen, 1.08 grams of hydrogen is required.

How many moles of NO2 form when<br> 63.25 g N2O5 decompose?<br><br> 2N₂O54NO₂ + O₂

KonstantinChe [14]

Answer:

1.1713 moles

Explanation:

RFM of N2O5=108

Moles of N2O5= mass/RFM= 63.25/108=0.5856 moles

Mole ratio of N2O5:NO2= 2:4

Therefore moles of NO2= 4/2*0.5856= 1.1713 moles

5) How many Kilograms are in 12 L of Chlorine Gas?

melamori03 [73]

Answer: 0.03798 kilograms

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given volume}}{\text {Molar Volume}}=\frac{12L}{22.4L}=0.535moles$

1 mole of chlorine gas $(Cl_2)$ weighs = 71 g

Thus 0.535 moles of chlorine gas $(Cl_2)$ will weigh = $\frac{71}{1}\times 0.535=37.98g=0.03798kg$ (1kg=1000g)

Thus there are 0.03798 kilograms in 12 L of chlorine gas.

How many different kinds of monomers are there in proteins?

zubka84 [21]

There are 20 different type of monomers present in proteins. Amino acids are in reality the monomers of proteins. Out of the 20 amino acids, only 9 are considered essential. The other 11 are of little use to the humans. The nine of the essential amino acids required by humans are Tryptophan, lysine, Histidine, Isoleucine, Valine, Threonine, Phenylalanine, Methionine and Leucine. The amino acids combine with one another to form different types of proteins. These proteins satisfy a number of our physical functional needs.
