He conditions needed to produce lightning have been known for some time. However, exactly how lightning forms has never been verified so there is room for debate.
Leading theories focus around separation of electric charge and generation of an electric field within a thunderstorm. Recent studies also indicate that ice, hail, and semi-frozen water drops known as graupel are essential to lightning development. Storms that fail to produce large quantities of ice usually fail to produce lightning.
Hope this helps!
Explanation:
5) Le Chatelier's principle says, when in a reversible reaction any of the concentration or temperature or pressure are changed, then the equilibrium shifts such a way to nullify the changes occurred. (hope you get it)
<h3 /><h3>6) 1.change in concentration </h3>
R ======= P
if concentration of reactant R is increased then eqm shifts towards the one with lower concentration ,that is product P.
<em><u>forward</u></em><em><u> </u></em><em><u>dire</u></em><em><u>ction</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>favoured</u></em><em><u>.</u></em>
<h3 /><h3>2.Change in temperature</h3>
if the above's reaction is endothermic,<em> </em>that is temp of product is low. So increasing temperature in such case reaction goes towards product.
<em><u>forward direction is favoured</u></em>.
If reaction is exothermic ,temp of reactant is more. So increasing temperature in such case, reaction goes towards reactants.
<em><u>forward direction is favoured</u></em>

Answer: a . is determined by the number of protons and neutrons it contains.
Explanation:
Atomic number is defined as the number of protons or the number of electrons that are present in an electrically neutral atom.
Atomic number = Number of protons = number of electrons
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
As the mass of electron is negligible as compared to mass of neutron and proton, the number of electrons does not influence the atomic mass of an element.
Answer:
491.4 g
Explanation:
This a stoichiometry question, let me repeat the reaction equation here;
2 Na + Cl2 --> 2 NaCl
The balanced reaction equation must serve as a guide in solving any problem on stoichiometry.
From the balanced reaction equation;
1 mole of chlorine gas yields 2 moles of sodium chloride
Therefore, 4.2 moles of chlorine gas yields 4.2 ×2/1 = 8.4 moles of sodium chloride.
Molar mass of sodium chloride= 23 + 35.5= 58.5 gmol-1
Mass of sodium chloride formed= number of moles × molar mass
Mass of sodium chloride formed= 8.4 × 58.5= 491.4 g
Answer:
A homogeneous mixture is a solid, liquid or gaseous mixture that has the same proportions of its components throughout any given sample. Conversely, a heterogeneous mixture has components in which proportions vary throughout the sample.
