Desalination is a process that takes away mineral components from saline water.
We know power=work done/time taken
power*time= work
100watt=0.1kw
total work in a day= power* time
0.1*5.5=0.55kwh
for 1 year total.energy is 0.55*365=200.75kwh
cost is 200.75*0.13=26.0975dollars
for 25 watt it is 0.025*5.5*365*0.13=6.524375 dollars
Answer:
10
Explanation: 5 moles of Oxygen + 3moles of Oxygen from Carbondioxide + 2 moles of Oxygen from water
Global warming affects many processes in biological ecosystems. Different species of flora and fauna change their habitats and geographical areas according to climate change and specific geographical environments. Areas of occurrence of specific species, for example insects in terrestrial areas and fish and arthropods in the seas and oceans, change. Bird habitats change, so migrations of some bird species may also be subject to modification. In the situation when forest areas dry out and turn into steppes and deserts, changes in natural habitats and areas of occurrence of species change and concern simultaneously many species of flora and fauna.
Total mass of mouthwash = volume*density
1 pint is 568.261 mL therefore 1.040 pints = 591.0 mL (4 significant figures)
Therefore mouthwash mass in a bottle = 591.0 mL * 0.851 g/mL = 503 g (3 s.f.)
In 160 bottles, ethanol mass = 509 g * 160 * 0.381 = 30700 g = 30.7 kg
