C₀=2 mol/l
c₁=0.400 mol/l
v₁=100.0 ml = 0.1 l
c₁v₁=c₀v₀
v₀=c₁v₁/c₀
v(H₂O)=v₁-v₀
v₀=0.1*0.400/2=0.02 l = 20 ml
v(H₂O)=100 - 20 = 80 ml
It is necessary to mix 20 ml of the feed solution and 80 ml of water.
The mesosphere is the coldest of the atmospheric layers. In fact it is colder than the Polar regions of the Earth cold enough to freeze water vapor into ice clouds. As you increase in altitude, temperature decreases The thermosphere is the layer to which this pattern does not apply.
They are called meteorologists. i hope this helped.
<h3><u>Answer;</u></h3>
El Nino
<h3><u>Explanation</u>;</h3>
- El Nino is a weather pattern that begins as a result in an increase in the water temperature at the surface of the Pacific ocean that produces a warm current.
- It is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean.
- It has an impact on ocean temperatures, the speed and strength of ocean currents together with the health of coastal fisheries. Its events occur irregularly at two- to seven-year intervals.
Answer:
A is on an island arc,
B is in the Andes
Explanation:
The subduction region is referred to as the subduction zone. When a plate slips underneath another, it forms a trench. Earthquakes resulting from the plate panelling often result in magma spilling across the underwater volcano trench. Island arcs are vast chains of active volcanoes with strong seismicity located along the converging tectonic plate borders. Much of the islands arcs emerge from the oceanic crust and also have originated from fall of the lithosphere into the mantle across the subduction zone. In the Andes mountain range, Under the South American plate the Nazca plate is subducting.
