Answer:
The weather represents the state of the atmosphere in a certain place, at a certain moment. <em>Usually, the weather is defined by evoking the most obvious characteristic of the atmosphere, so that it can be warm weather, cold or frosty weather, clear weather.
</em>
The characteristics that define the weather are the <u>meteorological elements.</u> These are:
- air temperature (expressed in degrees Celsius or Fahrenheit)
- air pressure (expressed in millimeters mercury column)
- wind direction and speed (wind direction is indicated by the cardinal or intercardinal point from which the wind blows, and the speed is expressed in m/s or km/h)
- nebulosity (the degree of coverage of the celestial vault with clouds, expressed in tenths of the visible celestial vault)
- the amount of precipitation represents the thickness of the water layer that would form if it stagnated on the earth's surface and is expressed in liters / m² or mm
Answer:
volcanic material in valleys
Explanation:
Below is the solution:
n equation showing conservation of mass of reactants and products:
<span>2H2O --> 2H2 & O2 </span>
<span>what is the mass of the oxygen gas produced, from 178.8 g H2O , (using molar masses: </span>
<span>178.8 g H2O @ (1mol O2)(@ 32.00 g/mol) / (2molH2O)(18.02g/mol) = </span>
<span>your answer (4 sigfigs): 158.8 g O2 </span>
<span>178.8 g H2O ---> 20.0 H2 & 158.8 O2</span>
