Answer:
We use coolant instead of water because when heated, water can start to accumulate the minerals that it has, and this can corrode the metal on your car. Other solution could be to use distilled water, but is will also corrode the metal of your radiator. One advantage of ethylene glycol is that prevents the corrosion in your radiator providing a protective coating to the metals.
<span>Sunis made of about 72 percent of hydrogen. The sun is also composed of about 26 percent helium and trace amounts of other elements — oxygen, carbon, neon, nitrogen, magnesium, iron and silicon.
so,if you want the element which made up MOST of sun than go for HYDROGEN. :)</span>
Answer:
The kind of bond formed depends on the identity of the bonding atoms and the shape of the molecule formed for covalent bonds.
Explanation:
There are various kinds of chemical bonds that could be present in a compound;
I) ionic bond
ii) covalent bond
iii) metallic bond
The kind of bond present in the compound depends on the elements involved in the bond. Metals and nonmetals mostly form ionic bonds win which electrons are transferred from metal to nonmetal.
Nonmetals commonly form covalent bonds with each other by sharing electrons in single, double and triple bonds. One may decide if the bond between two elements is ionic, covalent or polar covalent by looking at the electro negativity difference between the bonding atoms as well as the observed molecular geometry.
Finally, two metals are bonded by metallic bonds. This is the kind of bonds found in metallic crystals.
