forsale [732]

Answer:

read it first

Explanation:

Population change is governed by the balance between birth rates and death rates. If the birth rate stays the same and the death rate decreases, then population numbers will grow. If the birth rate increases and the death rate stays the same, then population will also grow.

What is the minimum pressure in kPa that must be applied at 25 °C to obtain pure water by reverse osmosis from water that is 0.2
Nadya [2.5K]

This is an application of osmotic pressure which is one of the colligative properties of substances. The formula of osmotic pressure is expressed as P = MRT where M is molarity , R is the gas constant and T is temperature. When M is equal to a total of 0.305 M and T is equal to 298 K ,  P should be equal to 7.46 atm

A tank of water was contaminated with a colored dye (D). To determine the concentration of D, an analyst took 5.0-mL solution fr
alekssr [168]

Answer:

0.005 M

Explanation:

Given data:

volume of sample solution ( volume of D ) = 5.0 mL

volume of added stock solution ( V1 ) = 5.0 mL

concentration of added stock solution ( N1 )  = 0.02 M

Total volume of concentration  ( V2 )= 10 mL = ( 5.0 mL + 5.0mL)

concentration of Total volume of sample ( C2 ) = 0.01

N2 = ( N1V1 ) / V2

     = ( 0.02 * 5 ) / 10 = 0.01 m

absorbance of sample solution ( A1 ) = 0.10

absorbance of additional sample solution ( A2 ) = 0.20

attached below is the remaining part of the detailed solution

How many grams of barium sulfate can be produced from the reaction of 2.54 grams sodium sulfate and 2.54 g barium chloride? Na2S
Rama09 [41]

Answer: 2.796 grams

Explanation:

Na_2SO_4+BaCl_2\rightarrow 2NaCl+BaSO_4

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

\text{Number of moles of sodium sulphate}=\frac{2.54g}{142g/mol}=0.018moles

\text{Number of moles of barium chloride}=\frac{2.54g}{208g/mol}=0.012moles

According to stoichiometry:

1 mole of BaCl_2 reacts with 1 mole of Na_2SO_4

0.012 moles of BaCl_2 will react with=\frac{1}{1}\times 0.012=0.012moles of Na_2SO_4

Thus BaCl_2 is the limiting reagent as it limits the formation of product. Na_2SO_4  is the excess reagent as (0.018-0.012)=0.006 moles are left unused.

1 mole of BaCl_2 produces 1 mole of BaSO_4

0.012 moles of BaCl_2 will produce=\frac{1}{1}\times 0.012=0.012moles of BaSO_4

Mass of BaSO_4=moles\times {\text {Molar mass}}=0.012\times 233=2.796g

Thus 2.796 grams of BaSO_4  are produced.
