Calculate the electronegativity difference of CH3OH
Maru [420]

You can't calculate the electronegativity difference of a single molecule you'll need a frame of reference to explain the electronegativity difference and properties arising due to the difference. Another term arise here is modified electronegativity that is calculated within the molecule between two atoms of different electronegativity and use to explain the nature of molecule wether they are electron withdrawing group or electron donating group and also used to compare the electronegativity with other molecule!

The actual yield of a certain reaction is 34.0 g, while the theoretical yield is 50.0 g. Calculate the percent yield.
anyanavicka [17]
The percent yield formula is % yield= (actual yield/theoretical yield) x 100 
34.0g/50.0g= .68 x 100 = 68.0% (theres three sig. figs.)

The cycle repeats when the carbon stored in the atmosphere as carbon dioxide gas is taken in.
Rzqust [24]

Answer:

Order of the cycle:

Step -1>>>>Step -4 >>>> Step -3 >>>>> step -2.

Explanation:

<u>Step -1:</u>

Carbon dioxide is taken in by plants during photosynthesis.

<u>Step -4;</u>

The animal eats a plant and uses its carbohydrates for energy.

<u>Step - 3</u>

The animal releases the carbon dioxide back into the atmosphere during respiration.

<u>Step -2</u>

The cycle repeats when the carbon stored in the atmosphere as carbon dioxide gas is taken in.

Therefore, order of the cycle is Step -1>>>>Step -4 >>>> Step -3 >>>>> step -2.

Please help me with this chemistry question. Image attached.
Leya [2.2K]

Answer:

Moles of zinc chloride produced are 0.09942 moles.

Explanation:

Zn+2HCl\rightarrow ZnCl_2+H_2

Mass of zinc used = 6.5 g

Moles of zinc =\frac{6.5 g}{65.38 g/mol}=0.09942 mol

According to reaction, 1 mol of zinc gives 1 mole of zinc chloride,then 0.09942 moles of zinc will give :

\frac{1}{1}\times 0.09942 =0.09942 mol of zinc chloride

Moles of zinc chloride produced are 0.09942 moles.
