Explain why world food shortages could be reduced by growing more algae.

One of the many awe-inspiring things about algae, Professor Greene explains, is that they can grow between ten and 100 times faster than land plants. In view of this speedy growth rate – combined with the fact they can thrive virtually anywhere in the right conditions – growing marine microalgae could provide a variety of solutions to some of the world’s most pressing problems.

Take, global warming. Algae sequesters CO2, as we have learned, but owing to the fact they grow faster than land plants, can cover wider areas and can be utilised in bioreactors, they can actually absorb CO2 more effectively than land plants. AI company Hypergiant Industries, for instance, say their algae bioreactor was 400 times more efficient at taking in CO2 than trees.

And it’s not just their nutritional credentials which could solve humanity’s looming food crisis, but how they are produced. Marine microalgae grow in seawater, which means they do not rely on arable land or freshwater, both of which are in limited supply. Professor Greene believes the use of these organisms could therefore release almost three million km2 of cropland for reforestation, and also conserve one fifth of global freshwater

liquid disilicon hexachloride reacts with water to form solid silicon dioxide, hydrogen chloride gas, and hydrogen gas. be sure
kodGreya [7K]

The liquid disilicon hexachloride reacts with water to form solid silicon dioxide, hydrogen chloride gas and hydrogen gas are

Si{2}Cl{6} (l)  +  4H{2}O (l)  ------ > 2SiO{2} (s)  +    6HCl (g)    +      H{2} (g)

When liquid disilicon hexachloride reacts with water to form solid silicon dioxide , hydrogen chloride gas and hydrogen gas , the following chemical equation is:

Si{2}Cl{6} (l)  +  H{2}O (l)  ------ > SiO{2} (s)  +    HCl (g)    +      H{2} (g)

now , we have to balance the eqaution,

                   Reactants            product

Si                      2                          1

Cl                      6                          1

H                      2                           3

O                      1                            2

Multiply 4 with H{2}O  2 with  SiO{2}  and 6 with HCL, we get

Si{2}Cl{6} (l)  +  4H{2}O (l)  ------ > 2SiO{2} (s)  +    6HCl (g)    +      H{2} (g)

now ,

                  Reactant       Product

Si                     2                   2

Cl                     6                   6

H                      8                   8

O                    4                     4

Thus, we get the desire equtions.

The liquid disilicon hexachloride reacts with water to form solid silicon dioxide, hydrogen chloride gas and hydrogen gas are

Si{2}Cl{6} (l)  +  4H{2}O (l)  ------ > 2SiO{2} (s)  +    6HCl (g)    +      H{2} (g)

What is the approximate size of solute particles in a solution?
murzikaleks [220]

The approximate size of solute particles in a solution is 1 nanometer.

Explanation:

Solute and solvent are the two components required to prepare a solution. Solute is the one which is dissolved in the solvent to prepare a solution. So solute should be of lesser concentration compared to the solvent. Also the particle size of solute should be lesser in size compared to the solvent for easy diffusion and substitution. Mostly it is seen that if the solute is finer and having a size of less than 1 nanometer can be easily dissolved in the solvent.

So for forming homogeneous solutions, the solute is considered to be of materials having the particle size of 1 nanometer for perfect dissolving.

Thus, the approximate size of solute particles in solution is 1 nanometer.

The diffusion flux is defined as: a) Mass, per unit surface area, per unit time b) Surface area, per unit time c) Time, per unit
s2008m [1.1K]

Answer:

The correct answer is option a.

Explanation:

Diffusion flux is defined as movement of mas of atoms diffusing through the unit area in per unit time.It measured in (kg/m^2 s).

J=\frac{1}{A}\frac{dM}{dt}

J = diffusion flux

A = Unit area A through which atoms moves.

M = mass of atoms passes in t interval of time.

Need help ASAP plzzzzzz​
oee [108]

Answer:

Biodiesel has a higher oxygen content (usually 10 to 12 percent) than petroleum diesel. ... Biodiesel is more chemically active as a solvent than petroleum diesel. As a result, it can be more aggressive to some materials that are normally considered safe for diesel fuel. Biodiesel is much less toxic than petroleum diesel.
