Ok they are both can formed by the same high pressure system . the heat waves are extended periods of above-normal temperatures . but the cold wave is an extended periods of below normal temperatures
If you're asking about the greatest amplitude of visible sunlight, then red light waves.
However if you're talking about the colors just in general, then radio waves.
Answer:
Check explanation section.
Explanation:
Yes, that is true. Sodium with chemical symbol Na belongs to the group 1 on the periodic table. Group 1 elements are known as Alkali metals. Other elements in the group are Caesium, lithium, Rubidium, francium and potassium.
Neon belongs to the noble gas of group 8/0.
Sodium is very reactive and and good conductor of electricity. Sodium reacts with water for the production of hydrogen (NB: this reaction is vigorous).
2Na(s) + 2H2O ------------> 2NaOH + H2(g).
They can react with nonmetals such as the halogens. For instance;
Na + Cl2 -------------------------------> 2NaCl.
Sodium is ductile and have low melting point( but high compared to neon).
Neon is not active chemically and it has no odour and no color
The standard entropy for the substances are as follows:
C6H12O2(s) = -212
<span>O2(g) = -205 </span>
<span>CO2(g) = -214 </span>
<span>H2O(l) = -70
</span>
We calculate the ∆S°r<span>eaction by the expression:
</span>∆S°rxn = ∆S°products - ∆S° reactants
∆S°rxn = (212+6x205)-(6x214+6x70)
∆S°rxn = -262 J/K ------> OPTION 3
