In a solid state, the molecules have the least amount of energy. They just stick close together and vibrate in place. As the molecules gain more energy, they are able to move around more freely. In the liquid state, the molecules have enough energy to sort of tumble over each other.

1. What do microorganisms share in common?​
alexgriva [62]

Answer:

Bacterial species are typified by their diversity. There are three notable common traits of bacteria, 1) lack of membrane-bound organelles, 2) unicellular and 3) small (usually microscopic) size.

Explanation:

What Are the Characteristics Common to All Bacteria?

Single-Celled. Perhaps the most straightforward characteristic of bacteria is their existence as single-celled organisms. ...

Absent Organelles. ...

Plasma Membrane. ...

Cell Walls. ...

DNA.

GUYS I NEED HELP THIS IS DUE TONIGHT !!!
kenny6666 [7]

Explanation:

To balance the reactions given, we must understand that the principle to follow is the law of conservation of matter.

Based on this premise, the number of moles of species on the reactant and product side must be the same;

 

      Li   +   Br₂  →    LiBr

Put a,b and c as the coefficient of each species

   aLi  + bBr₂ → cLiBr

balancing Li;

       a  = c

 balancing Br;

        2b  = c

 let a  = 1;

       c  = 1

        b = \frac{1}{2}  

or a = 2, b = 1 , c = 2

        2Li   +   Br₂  →    2LiBr

        P   +   Cl₂  →    PCl₃

Using the same method;

      aP  + bCl₂ → cPCl₃

balancing P;

          a  = c

balancing Cl;

          2b  = 3c

let a = 1;

     c  = 1

      b  = \frac{3}{2}

 or

  a  = 2, b  = 3, c  = 2

    2P   +   3Cl₂  →    2PCl₃

iii,

   H₂   +   SO₂  →   H₂S   +   H₂O

use coefficients a,b,c and d;

    aH₂   +   bSO₂  →   cH₂S   +   dH₂O

balancing H;

    2a = 2c + 2d

balancing S;

     b  = c

balancing O

    2b  = d

 let b  = 1,

      c = 1

       d  = 2

    a  = 3

    3H₂   +   SO₂  →   H₂S   +   2H₂O

At 450°C, ammonia gas will decompose according to the following equation: 2 NH3 (g)  N2 (g) + 3 H2 (g) Kc = 4.50 at 475˚C An u
velikii [3]

Answer:

0.2024 M

Explanation:

For the decomposition reactio given, let's do an equilibrium chart. Let's call the initial concentration of NH₃ as C:

2NH₃(g) ⇄ N₂(g) + 3H₂(g)

C 0 0 Initial

-2x +x +3x Reacts (stoichiometry is 1:1:3)

C - 2x x 3x Equilibrium

3x = 0.252

x = 0.084 M

The equilibrium constant (Kc) is the multiplication of the concentrations of the products elevated by their coefficients, divided by the multiplication of reactants concentrations elevated by their coefficients.

Kc = ([H₂]³*[N₂])/([NH₃]²)

4.50 = [(0.252)³*(0.084)]/(C - 2*0.084)²

4.50 = 0.00533/(C - 0.168)²

4.50 = 0.00533/(C² - 0.336C + 0.028224)

4.50C² - 1.512C + 0.127008 = 0.00533

4.50C² - 1.512C + 0.121678 = 0

Solving the equation by a graphic calculator, for C > 0.168

C = 0.2024 M
