What is the mass of 0.257 mol of calcium nitrate?
poizon [28]

Answer: 42.14 g

Explanation:      calcium nitrate -  Ca(NO_{3} )_{2}

                   , the molar mass of calcium nitrate = 164 g

<h3>                   formula used = given mass/molar mass= no of moles </h3>

                   mass required =0.257*164

                                               =42.14 g

How many liters of C3H6O are present in a sample weighing 25.6 grams?
Romashka [77]

Answer:

V = 0.0327 L.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the liters of C3H6O by the definition of density. We can tell the density of this substance as that of acetone (0.784 g/mL) and therefore calculate the liters as shown below:

V=25.6g*\frac{1mL}{0.784g}*\frac{1L}{1000mL}\\\\V=0.0327L

Regards!

The thing that the discovered is a "partially molten state"<br> What would that be considered as
castortr0y [4]

Answer:

liquid and solid

Explanation:

Research scientists of scotland discovered a new state of the matter which consists of both liquid and solid. Scientifically there are  three states of matter i.e Solid, Liquid and Gas, but now there are chances of one more state of matter which which consists of more than one state of the existing three states of the matter which have both liquid and solid state.  

This discovery took place with the help of artificial intelligence of today's world which is transforming the world  day by day.

The State is considered to be true as it is thermodynamically stable state of the matter.

raketka [301]
True.
where the atom is the smallest (tiny) particle of an element, the atom may be neutral or ionized, and its size is around 100 picometers. The atom composed of a nucleus and one or more electrons (negative charge) bound to the nucleus, the nucleus contains protons (positive charge) and neutrons.

In the step gradient separation, four separate fractions were collected. How were these related to the polarities of the column
max2010maxim [7]
<span>  These related to the polarities of the column and of the eluting solvent </span><span>When you run a column are 
 1) always start with a more non-polar solvent ratio and SLOWLY increase the polarity of the solvent.
1) Columns are generally made with silica which is highly polar, so compounds that are more polar in nature will interact with the silica more than those that are non-polar.
 3) The first fractions to come out should be most non-polar, with each fraction collected after that being more and more polar.
hope this helps</span>
