Answer:
when the solution is heated and reaches its saturation point thus starts forming crystals thus crystals starts forming hence crystallisation takes place
The answer to this question would be:5 mol
To answer this question, you need to know the chemical equation of mg3(po4)2 when forming an ion. The equation should be: <span>mg3(po4)2= 3Mg(2+) +2PO4(3-)
That means for 1 mol of </span><span>mg3(po4)2 there will be 3 magnesium(cation) ion and 2 phosphates(anion) ion, the result would be 5 mol of ion.</span>
Answer:
<h2>Density = 0.8 g/cm³</h2>
Explanation:
The density of an object can be found using the formula
<h3>
</h3>
From the question
mass of kerosene = 36.4 g
volume of kerosene = 45.6 mL
To find the density substitute the values into the above formula and solve
We have
<h3>
</h3>
= 0.7982
We have the final answer as
<h3>Density = 0.8 g/cm³</h3>
Hope this helps you
Answer:
The first step in forming the ch3cl lewis structure is drawing out all the atoms that exist within the molecule or ion being studied. Then, each atom must have its atomic number written above it. After this, draw lines between every bonded pair of non-identical electrons on adjacent atoms (bonded pairs are called “bonds”).
