Answer:

The question has some part missing which I have added in the attachment.

Explanation:

The reactions given occur under certain reagents, which we are told to pick for each of the reaction synthesis. Conventionally, halogens have the ability to undergo addition reactions with hydrocarbons by breaking down the double or triple bond in them to a single bond, this usually occur by electron donation and electron acceptor.

The attachment shows the reactions and the necessary reagents required for each

What kind of change alters the form of an object without changing what type of matter it is?
vlabodo [156]

that would be physical change cuz your only changing it PHYSICALLY ya know wat im sayin...

a physical change is a change that does not change the composition of the substance. a physical change does not change the molecules of the substance. (they mean the same thing) but no new substance is made from a physical change it stays the same substance as it is...and probably.....always...wooooooo

-exp would be: cutting, tearing, folding, painting, melting, freezing, mixing, and evaporating.

a sample of mass 6.814grams is added to another sample weighing 0.08753 grams. the subsequent mixture is then divided into exact
Alexxx [7]

Answer:

Final\ Mass = 17.560943085g

Explanation:

Given

Sample\ Mass = 6.814g

Additional\ Mass = 0.08753g

Yield = 7.6335

Required

Determine the final mass

First we need to determine the total mass after the sample mass is added to an additional sample;

Total\ Mass = Additional\ Mass + Sample\ Mass

Total\ Mass = 0.08753g + 6.814g

Total\ Mass = 6.90153g

Next, divide the total mass by 3

New\ Mass = \frac{Total\ Mass}{3}

New\ Mass = \frac{6.90153g}{3}

New\ Mass = 2.30051g

The final mass is calculated as follows;

Final\ Mass = New\ Mass * Yield

Final\ Mass = 2.30051g * 7.6335

Final\ Mass = 17.560943085g

<em>Hence, the final mass is 17.560943085g</em>

morpeh [17]

Answer:

32.7 grams of Zn will remained in the crucible after cooling.

Explanation:

2ZnS+3O_2 \rightarrow 2ZnO + 2SO_2..[1]

ZnO+C\rightarrow Zn+CO..[2]

Adding [1] + 2 × [2] we get:

2ZnS+3O_2+2C \rightarrow 2Zn + 2CO+2SO_2..[3]

Moles of ZnS in crucible = 0.50 mol

According to reaction [3]. 2 moles of ZnS gives 2 moles of Zn.

Then 0.50 moles of ZnS will give:

\frac{2}{2}\times 0.50 mol=0.50 mol of Zn.

Mass of 0.50 moles of Zn =

= 0.50 mol × 65.4 g/mol =32.7 g

32.7 grams of Zn will remained in the crucible after cooling.
