Answer:

7.28 mol

Explanation:

2 NaOH + H₂SO₄ = 2 H₂O + Na₂SO₄ -------------------(1)

mole fraction for the reaction is;

2 : 1 = 2 : 1

Number of moles of H₂SO₄ = 7.28 mol

1 mol of H₂SO₄ shall form 1 mole of Na₂SO₄

therefore,

7.28 mol of H₂SO₄ shall form 7.28 mole of Na₂SO₄

The condensed structural formula of the product of the reaction of 2,7-dimethyl-4-octene with hydrogen and metal catalyst.

Ch3 CH(CH3) CH2 CH2 CH2 CH2 CH(CH3) CH3

Equation is as follows

CH3 CH(CH3) CH2 C=C CH2 CH(CH3) CH3 + H2→

CH3 CH(CH3)CH2 CH2 CH2 CH2 CH(CH3) CH3

metal catalyst example is nickel and the name of structure formed is
2,7- dimethyl octane

Given the equation: 2H2 + O2 → 2H2O, how many moles of oxygen are needed to react with 13 moles of hydrogen

bulgar [2K]

Explanation:

2H2 + O2 = 2H2O

2mol. 1mol. 2mol

2mol reacts with 1mol

13mol reacts with x

x=13mol × 1mol

2mol

x= 13mol

2mol

x= 6.5mol of oxygen

A biology student is studying ways to grow crops in soils that are high in salts and other dissolved solids. To determine whethe

lana [24]

Answer:

b. Plants grown in typical soil

Explanation:

The experimental control is one that controls for the condition you have changed. The student was changing the salt concentration. But she has to also grow plants in typical conditions to make sure that the plants are able to grow typically. It ensures that any changes made are the result of the changing experimental conditions, not some other factor.

This controls for unforeseen circumstances, such as that none of the plants grow (maybe the seeds were faulty, maybe the weather was poor). It allows you to make conclusions based on what would have happened if you changed nothing. It is vital for ALL scientific experiments!

When you placed the chromatography paper in the Petri dish containing the salt-water solution solvent, what would have happened

BaLLatris [955]

Answer:

It will not achieve the desired separation

Explanation:

Chromatography is a separation method that involves the use of a stationary phase and a mobile phase. The stationary phase is immobile, in the particular instance of this question, the stationary phase is paper. The mobile phase is the appropriate solvent, in this case, a salt-water solution.

If the level of solvent is above the dye spots, it will introduce error into the separation. The solvent (if volatile) may evaporate without drawing up and separating the solute. Secondly, the solvent may simply dissolve the spots without achieving any meaningful separation of the components in the system. This second reason is particularly why the salt solution must be below the dye spots in this chromatographic separation.
