Answer:  Selectivity of mineral nutrients absorbed by roots

Explanation:

The Casparian strip in the plants are waxy coating found in the roots of the plant which helps in absorbing excess of water into the plants.

These strips thickens the walls, thus preventing the excess of soil solution from being pulled by the roots into the central part of the plant.

It helps in selecting the type and amount of nutrient into the plant but the plant having no Casparian strip will reduce the selectivity of the nutrients.

What mass of aluminum sulfate is required to precipitate all of the Ba?? out of 45.0 mL of 0.548 M barium nitrate solution? 3 Ba
Verizon [17]

Answer:

2.82 g

Explanation:

Step 1: Write the balanced precipitation reaction

3 Ba(NO₃)₂ (aq) + Al₂(SO₄)₃ (aq) ⇒ 3 BaSO₄(s) + 2 Al(NO₃)₃(aq)

Step 2: Calculate the reacting moles of Ba(NO₃)₂

45.0 mL (0.0450 L) of 0.548 M Ba(NO₃)₂ react.

0.0450 L × 0.548 mol/L = 0.0247 mol

Step 3: Calculate the moles of Al₂(SO₄)₃ that react with 0.0247 moles of Ba(NO₃)₂

The molar ratio of Ba(NO₃)₂ to Al₂(SO₄)₃ is 3:1. The reacting moles of Al₂(SO₄)₃ are 1/3 × 0.0247 mol = 8.23 × 10⁻³ mol

Step 4: Calculate the mass corresponding to 8.23 × 10⁻³ moles of Al₂(SO₄)₃

The molar mass of Al₂(SO₄)₃ is 342.2 g/mol.

8.23 × 10⁻³ mol × 342.2 g/mol = 2.82 g

How would you figure the number of neutrons in an atom?
Sonbull [250]
<span>Mass Number = (Atomic Number) + (Number of Neutrons) so you solve for the Number of Neutrons and you get:
Number of Neutrons = (Mass number) - (Atomic Number) 

Mass Number equals protons plus neutrons, round atomic weight to nearest whole number
Atomic Number equals number of Protons</span>

Crude oil may contain hundreds of different types of hydrocarbons. Some examples include: Butane(C4H10) Dodecane (C12H26) Octane
Klio2033 [76]

Answer:

The answer to your question is below

Explanation:

Material             Classification               Reason

Crude oil             Mixture                         Because we know that crude oil

                                                                 is composed of different substances.

Butane                Compound                   Because it is composed of carbon

                                                                 and hydrogen

Dodecane           Compound                  Because it is composed of carbon

                                                                and hydrogen.

Octane                Compound                  Because it is composed of carbon and

                                                                 hydrogen.

Benzene              Compound                  It is also composed of carbon and

                                                                 hydrogen.

Gasoline              Mixture                         It is a combination of hydrocarbons

Kerosene             Mixture                        It is a combination of hydrocarbons

Oxygen                Element                       We can find it in the periodic table.

Carbon dioxide   Compound                   It is composed of carbon and oxygen.

Water                   Compound                   It is composed of hydrogen and        

                                                                  oxygen.
