  • Hydrometeorology it’s a branch of meteorology and hydrology that studies the transfer of water and energy between the land face and the lower atmosphere.
  • They regard for a dominant bit of natural hazards and do in all regions of the world, although the frequency and intensity of certain hazards and society’s vulnerability to them differ between regions.
  • Severe storms, strong winds, cataracts, and famines develop at different spatial and temporal scales, but all can come disasters that beget significant structure damage and claim hundreds of thousands of lives annually worldwide. hourly, multiple hazards can do contemporaneously or spark slinging impacts from one extreme rainfall event.
  • In addition to causing injuries, deaths, and material damage, a tropical storm can also affect in flooding and mudslides, which can disrupt water sanctification and sewage disposal systems, beget overflow of poisonous wastes, and increase propagation of mosquito- borne conditions

Therefore these are the hydro-meteorological hazards.

Zn(s)+2HCl(aq)-&gt;ZnCl2(aq)+H2(g)
kobusy [5.1K]
To answer this we need to assume that at STP 1 mol of a substance is equal to 22.4 L. We use this data for the calculations. 
Statement 1
2 mol HCl (1 mol H2 / 2 mol HCl) = 1 mol H2 thus at STP 22.4 L H2
<em>This statement is false.</em>
Statement 2
1 L Zn (1 mol Zn / 22.4 L Zn) (1 mol H2 / 1 mol Zn) (22.4 L H2 / 1 mol H2) = 1L H2
<em>This statement is true.</em>
Statement 3
65.39 g Zn (1 mol Zn / 65.39 g Zn) (1 mol H2 / 1 mol Zn) = 1 mol H2
<em>This statement is true.</em>
Statement 4
1L HCl (1 mol HCl / 22.4 L HCl)(1 mol H2 / 2 mol HCl) = 0.022 mol H2
<em>This statement is false.</em>
