Answer:
If you add water to sulfuric acid, it can boil and spit and you may get a nasty acid burn.
Explanation:
<span>2) H-2 and He-3 N(n)=1
4) H-3 and He-4 N(n)=2</span>
So you add the individual mass of each individual element times the subscript ( no subscript= 1 )
Explanation:
<em>For a given substance, the molar heat of fusion basically tells you one thing from two perspectives</em>
<em>For a given substance, the molar heat of fusion basically tells you one thing from two perspectiveshow much heat is needed in order to melt one mole of that substance at its melting point</em>
<em>For a given substance, the molar heat of fusion basically tells you one thing from two perspectiveshow much heat is needed in order to melt one mole of that substance at its melting pointhow much heat must be removed in order to freeze one mole of that substance at its freezing point</em>
<em>For a given substance, the molar heat of fusion basically tells you one thing from two perspectiveshow much heat is needed in order to melt one mole of that substance at its melting pointhow much heat must be removed in order to freeze one mole of that substance at its freezing pointIt is very important to realize that the molar enthalpy of fusion will carry a positive sign when you're dealing with melting and a negative sign when you're dealing with freezing.</em>
Here we have to justify the work of scientists to generate more unknown elements after atomic number 104 which are so unstable and cannot be obtained in nature.
It is fact that the stability of the super heavy element is hard to obtain, as when there are so much proton and neutron at the nucleus of such element makes it so unstable.
So the try to make more unknown element to enlarge the periodic table is not justified as per the stability and utility of such elements are concerned. But in fact it helps to get the new elements which may exist and may have some radioactivity which can be used.
But apparently the making of new material in laboratory to expand the periodic table is not justified.
