I FORGOT HOW TO SHOW THE SLIDE BUT -Yosef is so intrigued by what he sees in his microscope that he walks to a nearby pond and c

ollects a sample of pond water to learn more about paramecium. He uses a single drop of the pond water to create a wet mount slide, which allows him to see living paramecia moving around in the water, unlike the processed and dyed paramecia in the prepared slide How do the structures observed under magnification help the organism carry out basic functions of life? - PLS HELP IT WAS DUE YESTERDAY

The structure of paramecium observed under magnification that helps the organism carry out basic functions of life is ; CILIA

The paramecium has a oral surface and a dorsal body surface that is covered with pellicles ( elastic firm membrane ) that supports the cell membrane of the paramecium.  while The whole body of a paramecium is covered with Cilia ( hair like filaments ) that supports the propelling movement of the paramecium and the movement of food particles into the mouth of the paramecium.

The basic function of a paramecium are ; (i) movement and ( ii ) feeding. the CILIA is the structure that helps the organism to carry out these functions.

Hence we can conclude that structure of paramecium observed under magnification that helps the organism carry out basic functions of life is CILIA .

Be sure to answer all parts. Write the balanced equations corresponding to the following rate expressions: a) rate = − 1 3 Δ[CH4
Alinara [238K]

Answer : The balanced equations will be:

(a) 3CH_4+2H_2O+CO_2\rightarrow 4CH_3OH

(b) 2N_2O_5\rightarrow 2N_2+5O_2

(c) 2H_2+2CO_2+O_2\rightarrow 2H_2CO_3

Explanation :

The general rate of reaction is,

aA+bB\rightarrow cC+dD

Rate of reaction : It is defined as the change in the concentration of any one of the reactants or products per unit time.

The expression for rate of reaction will be :

\text{Rate of disappearance of A}=-\frac{1}{a}\frac{d[A]}{dt}

\text{Rate of disappearance of B}=-\frac{1}{b}\frac{d[B]}{dt}

\text{Rate of formation of C}=+\frac{1}{c}\frac{d[C]}{dt}

\text{Rate of formation of D}=+\frac{1}{d}\frac{d[D]}{dt}

Rate=-\frac{1}{a}\frac{d[A]}{dt}=-\frac{1}{b}\frac{d[B]}{dt}=+\frac{1}{c}\frac{d[C]}{dt}=+\frac{1}{d}\frac{d[D]}{dt}

From this we conclude that,

In the rate of reaction, A and B are the reactants and C and D are the products.

a, b, c and d are the stoichiometric coefficient of A, B, C and D respectively.

The negative sign along with the reactant terms is used simply to show that the concentration of the reactant is decreasing and positive sign along with the product terms is used simply to show that the concentration of the product is increasing.

Now we have to determine the balanced equations corresponding to the following rate expressions.

(a) Rate=-\frac{1}{3}\frac{d[CH_4]}{dt}=-\frac{1}{2}\frac{d[H_2O]}{dt}=-\frac{d[CO_2]}{dt}=+\frac{1}{4}\frac{d[CH_3OH]}{dt}

The balanced equations will be:

3CH_4+2H_2O+CO_2\rightarrow 4CH_3OH

(b) Rate=-\frac{1}{2}\frac{d[N_2O_5]}{dt}=+\frac{1}{2}\frac{d[N_2]}{dt}=+\frac{1}{5}\frac{d[O_2]}{dt}

The balanced equations will be:

2N_2O_5\rightarrow 2N_2+5O_2

(c) Rate=-\frac{1}{2}\frac{d[H_2]}{dt}=-\frac{1}{2}\frac{d[CO_2]}{dt}=-\frac{d[O_2]}{dt}=+\frac{1}{2}\frac{d[H_2CO_3]}{dt}

The balanced equations will be:

2H_2+2CO_2+O_2\rightarrow 2H_2CO_3

Sulfuric acid (H2SO4) is prepared commercially from elemental sulfur using the contact process. In a typical sequence of reactio
Elan Coil [88]
I believe the end result is still 83 moles since there is never an amount of sulfur atoms added to the initial amount, but rather oxygen and water is repeatedly added to it. To find it's weight, first find the molar mass of H2SO4:

H2 + S + O4 = 2.00 + 32.1 + 64.0 = 98.1 g/mol

and mass = (98.1 g/mol)(83 mol) = 8142.3 g

rounded to 8.1 x 10^3 g assuming 100% yield?
