How would local residents of a place be affected by changes in the hydrosphere? (please help!!)

The hydrosphere is needed to support human existence. It provides drinking water, water for agricultural purposes, and food and nutrients from fish and plants.
Without hydrosphere the atmosphere will no longer be able to carry up the evaporated water, as well as pour down the water, leaving the biosphere to die.
It will affect all organisms because they won’t be able to survive with water.

— hope it helps!! :)

Answer:

Humans have impacted the hydrosphere drastically and will only continue to due so based on population needs. Global climate change, water pollution, damming of rivers, wetland drainage, reduction in stream flow, and irrigation have all exerted pressure on the hydrosphere's existing freshwater systems.

Hope it helps :)

The molecular weight of table salt, NaCl, is 58.5 g/mol. A tablespoon of salt weighs 6.37 grams. Calculate the number of moles o

cestrela7 [59]

Answer:

The number of moles of salt in one tablespoon is = 0.11 mole

Grams cancel each other.

Explanation:

Moles : It is the unit of quantity . It is the mass of the substance present in exactly 12g of C-12.

$moles=\frac{given\ mass}{Molar\ mass}$

Moles Calculation:

Given mass = 6.37 gram

Molar mass = 58.5 g/mol

$moles=\frac{6.37}{58.5}$

= 0.1088

= 0.11 mole

Units calculation

$moles=\frac{given\ mass}{Molar\ mass}$

$moles=\frac{g}{g/mole}$

$moles=\frac{g}{g}\times mole$

g ang g cancels each other

moles = moles

Hence unit = gram (g ) cancel each other.

Gas is heated from 480. K to 750. K and the pressure is kept constant, what final volume would result if the original volume was

attashe74 [19]

Charles law gives the relationship between volume and temperature of gas.
It states that at constant pressure volume is directly proportional to temperature
Therefore
V/ T = k
Where V - volume T - temperature in kelvin and k - constant
V1/T1 = V2/T2
Parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
Substituting the values in the equation
267 L/ 480 K = V / 750 K
V = 417 L
Final volume is 417 L
