Answer:
lose or share electrons in such a way that the outer shells become chemically complete
Explanation:
Most interactions among atoms take place in the outermost shell of each atom. The number of each electron in this shell determines how an atom combines with other atoms to form compounds. When atoms combine they gain, lose or share electrons in such a way that the outer shells become chemically complete.
Answer:
421,787 moles.
Explanation:
No. of Molecules of H20=2.54×10²⁹
1 mole=6.022×10²³=Avagadro No.
No. of moles=Given no. of moles/Avagadro No.
=(2.54×10²⁹)/(6.022×10²³)=421,786.782=421,787(approx)
Answer:
Acid + Base -------> Salt + Water
Explanation:
The reaction between an acid and bases is called a neutralization reaction. The result of the reaction is salt and water. For example, when hydrochloric acid(acid) and sodium hydroxide(base) react they form sodium chloride(salt) and water. Also, heat is evolved.
Example:
HCl + NaOH ----------> NaCl + H2O
HCl is hydrochloric acid.
NaOH is sodium hydroxide which is a base.
NaCl is sodium chloride which is a salt.
H2O is water.
Heat<span> can be </span>transferred<span> from </span>one place<span> to </span>another<span> by three methods: conduction in solids, </span>convection<span> of fluids and radiation through anything that will allow radiation to pass. The method used to </span>transfer heat<span> is usually the </span>one<span> that is the most efficient.</span>
