Less plankton would mean that all the organisms that eat plankton would start to die off because they have no source of energy.

The electrolyte of the following is:
ozzi
An electrolyte is a term used to describe a compound that can dissociate into ions as it is nothing but an ionic compound, a salt made up of a positively charged cation and negatively charged anion.

Here the correct answer is D. Since there are no hydrocarbons or any other organic compound, that do not possess partial let alone full charges, all of them can dissociate in solution to give their ions.

This allows for the solution to be able to conduct electricity.

Helppppppp! why should i use spr??
Viktor [21]

SPR can be used in order to do real time monitoring and to evaluate the advancement of compounds.

<h3>Why should we use SPR?</h3>

SPR provide information to evaluate whether or not compounds should advance to the next stage of investigation. It also provides real-time monitoring.

So we can conclude that SPR can be used in order to do real time monitoring and to evaluate the advancement of compounds.

Show the calculation of the molar mass (molecular weight) of a solute if a solution of 5.8 grams of the solute in 100 grams of w
Leni [432]

Answer : The molar mass of solute is, 89.9 g/mol

Explanation : Given,

Mass of solute = 5.8 g

Mass of solvent (water) = 100 g

Formula used :  

\Delta T_f=K_f\times m\\\\T_f^o-T_f=T_f\times\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Mass of water}}

where,

\Delta T_f = change in freezing point

T_f^o = temperature of pure solvent (water) = 0^oC

T_f = temperature of solution = 1.20^oC

K_f = freezing point constant of water = 1.86^oC/m

m = molality

Now put all the given values in this formula, we get

(0^oC)-(1.20^oC)=1.86^oC/m\times \frac{5.8g\times 1000}{\text{Molar mass of solute}\times 100g}

\text{Molar mass of solute}=89.9g/mol

Therefore, the molar mass of solute is, 89.9 g/mol

An 11.2 L sample of gas is determined to contain 0.5 moles of nitrogen. At the same temperature and pressure, how many moles of
Volgvan

Answer:

0.89 moles of N2 gas

Explanation:

From Avogadro's law:

V1/n1 = V2/n2

n2 = V2n1/V1

V1=11.2L

V2= 20L

n1=0.5 moles

n2 = ??

Therefore

n2= 20×0.5/11.2= 0.89 moles
