The rules of IUPAC followed for hydrocarbon are

a) We will first find out the longest chain of carbon in the given organic compound  including triple bond

the root name will be "hex" as number of carbon atoms in longest chain is six.

b) The triple bond will be assigned minimum number locant. the locant will be 2 .

The primary suffix will be "yne"

hence

hex-2-yne

c) we will give locant number to methyl group (present as substituent)

it will be "4"

Thus the completer IUPAC name will be

4-methylhex-2-yne or 4-methyl-2-hexyne [as given in the options]

Ammonium perchlorate is the solid rocket fuel used by the U.S. Space Shuttle. It reacts with itself to produce nitrogen gas , ch
SpyIntel [72]

Answer:

2.94 g of water are produced by this decomposition

Explanation:

We need to determine the reaction to solve this problem:

The reactant is the ammonium perchlorate

The products are N₂, Cl₂, O₂ and H₂O

The reaction is: 2NH₄ClO₄ →  N₂ + Cl₂ + 2O₂ + 4H₂O

We convert the mass of the reactant to moles:

9.6 g . 1 mol / 117.45 g = 0.0817 moles

Ratio is 2:4. Let's make a rule of three:

2 moles of perchlorate produce 4 moles of water.

Then, 0.0817 moles of perchlorate will produce (0.0817 . 4)/2 = 0.163 moles

We convert the moles of produced water, to mass (g)

0.613 mol . 18 g / 1mol = 2.94 g

B. If 10.0 g iron reacts with oxygen, how many grams of iron (III) oxide should be<br> produced?
Setler79 [48]

Answer:

14.29g

Explanation:

First, let us write a balanced equation for the reaction. This is illustrated below below:

4Fe + 3O2 —> 2Fe2O3

Next, let us calculate the mass of Fe that reacted and the mass of Fe2O3 produced from the balanced equation. This is shown below:

Molar Mass of Fe = 56g/mol

Mass of Fe from the balanced equation = 4 x 56 = 224g

Molar Mass of Fe2O3 = (56x2) + (16x3) = 112 + 48 = 160g/mol

Mass of Fe2O3 from the balanced equation = 2 x 160 = 320g

From the balanced equation,

224g of Fe produced 320g of Fe2O3.

Therefore, 10g of Fe will produce = (10x320)/224 = 14.29g of Fe2O3

From the calculations made above, 10g iron(Fe) produced 14.29g of iron(iii) oxide (Fe2O3)

At 25 °C, what is the hydroxide ion concentration, [OH–], in an aqueous solution with a hydrogen ion concentration of [H ] = 4.8
Gekata [30.6K]
H₂O = H⁺ + OH⁻

If the H⁺ ion is 2M, the OH⁻ ion is M.

So, the OH⁻ ion is 4.8 x 10⁻⁸ / 2 = 2.4 x 10⁻⁸
