Answer:
- Option C) the chance of water-borne diseases.
Explanation:
When a <em>flood </em>happens, water will lpotentially get contaminated by several causes which include the overflow of untreated wastewater, the decomposition of the carcasses of animals and people, and the chemical contamination from industries.
In general, biochemical and chemical hazards are present in the water, after a flood, which means that the authorities and population should take extreme care for the use and intake of water: chemical treatment (use of chlorine), boil water. As usual, children and the elderly are the most at risk in those conditions.
Answer:
104.352°C
Explanation:
Data Given:
Boiling point of water = 100.0°C
Kb (boiling point constant = 0.512°C/m
Concentration of the Mg₃(PO₄)₂ = 8.5 m
Solution:
Formula Used to find out boiling point
ΔTb = m.Kb . . . . . . (1)
where
ΔTb = boiling point of solution - boiling point of water
So,
we can write equation 1 as under
ΔTb = Tb (Solution) -Tb (water)
As we have to find out boiling point so rearrange the above equation
Tb (Solution) = m.Kb + Tb (water) . . . . . . . (2)
Put values in Equation 2
Tb (Solution) = (8.5 m x 0.512°C/m ) + 100.0°C
Tb (Solution) = 4.352 + 100.0°C
Tb (Solution) = 104.352°C
so the boiling point of Mg₃(PO₄)₂ 8.5 m solution = 104.352°C
The answer would be B since it forms a solid
Cuando se combina con oxígeno e hidrógeno, el carbono puede formar muchos grupos de compuestos biológicos importantes que incluyen carbohidratos (azúcares), lignanos (importantes en las plantas), quitinas (el componente principal de las paredes celulares de los hongos, los exoesqueletos de los artrópodos), alcoholes, lípidos y grasas (triglicéridos) y carotenoides.
