The low pressure system wind flow in a counterclockwise direction toward the center because low pressure are connected, and in fact often generally, by upper atmosphere with winds. Winds generally blow from high pressure to low pressure areas at the surface. The direction of deflection is caused by the rotation of the Earth and the resulting Coriolis effect.
A way to remember this is.....some stoners like to get "high around the clock" (as in clockwise, but please don't do this!!)
Low pressure systems usually bring cloudy stormy conditions, while high pressure system bring clear bright skies and in the summer, warm weather.
Ammonium iodide, or NH₄I, is a salt. Since all salts are strong electrolytes, when ammonium iodide is dissolved in water, it would dissociate into ammonium ions and iodide ions. Hence, the major species present would be: <em>NH₄⁺ and I⁻ ions</em>.
Answer : The formula of the gas produced is,
(phosphine gas)
Explanation :
According to the question, when sodium phosphide is treated with water then it react to give phosphine gas and sodium hydroxide.
The balanced chemical reaction will be:

By Stoichiometry of the reaction we can say that:
1 mole of sodium phosphide reacts with 3 moles of water to give 1 mole of phosphine gas and 3 moles of sodium hydroxide.
Thus, the formula of the gas produced is,
(phosphine gas)
