<span>The appropriate response is filtration. Filtration is any of different mechanical, physical or organic operations that different solids from liquids by including a medium through which just the liquid can pass. The liquid that goes through is known as the filtrate</span>

<span>The correct answer would be "filtration". It's a process that has operations that separate solids from fluids. This is done simply by adding a medium through which only the fluid can pass. After the fluid passes through a certain medium it it's called a filtrate. </span>

Calculate the percent yield of (4-chlorophenyl)bis(4-methoxyphenyl)methanol if the actual isolated mass is 0.15 g.
laila [671]

Answer:

This question is incomplete

Explanation:

This question is incomplete. However, in order to calculate the percentage yield of an extraction/isolation, the formula to be used is below

percent yield = isolated mass/total mass × 100

The mass of the yield (which can also be referred to as isolated mass) was provided to be 0.15 g but the total mass of the (4-chlorophenyl)bis(4-methoxyphenyl)methanol was not provided.

In the completed question that has the total mass or the values to obtain the total mass, the formula mentioned earlier should be used.

there are 1540 megawatts of wind-generated electricity produced globally every year. This amount is equivalent to how many kilow
Reptile [31]

1.54 x 10⁶kW

Explanation:

The problem here is converting from megawatts into kilowatts.

  Given 1540megawatts.

The mega- and kilo- watts are prefixes that denotes multiples of units.

  1 megawatt = 10⁶watts

  1 kilowatt = 10³watts

Now given 1540megawatts power to Kilowatt power;

   We see that :

   1000kW = 1mW

 1540mW x \frac{1000kW}{1mW} = 1.54 x 10⁶kW

Find the number of moles in 3.30 g of (NH4)2SO4?
Vesnalui [34]

Hey there!

Molar mass ( NH4)2SO4 =  132.1395 g/mol

So:

1 mole  ( NH4)2SO4 ---------------- 132.1395 g

moles (NH4)2SO4 ----------------- 3.30 g

moles (NH4)2SO4 = 3.30 * 1 / 132.1395

moles (NH4)2SO4 = 3.30 / 132.1395

=> 0.0250 moles of (NH4)2SO4

Answer A


Hope that helps!
