Answer:  The answer is:  " 7.81 kg " .

___________________________________________________

Explanation:

___________________________________________________

Note the exact conversion:   1000 g = 1 kg ;

0.00781 g = ? kg :

So:  To convert "0.0781 g" ; to "units in kg" ;

            →  we multiply the value:  0.00781 g ;  by "1000" ;

So:  Given:  " 0.00781 g " ;  

           →  we move the decimal point "3 (three) spaces forward" ;

   to get:  " 7.81 kg " .

tatiyna

Answer:

12.4 × 10∧3 atoms

Explanation:

Given data:

moles of oxygen molecule= 1.0000 x 10-20 mol

atoms =?

Solution:

32 g O2 = 1 mol = 6.02 × 10∧23

1.0000 x 10∧-20 mol × 6.02 × 10∧23 × 2 = 12.4 × 10∧3 atoms

Hydrogen sulfide decomposes according to the following reaction: 2H2S(g) ⇋ 2H2(g) + S2(g) Kc=9.30x10-8 at 700.°C.If 0.45 mol of
Natalija [7]

Answer:

[H₂] = 1.61x10⁻³ M

Explanation:

2H₂S(g) ⇋ 2H₂(g) + S₂(g)

Kc = 9.30x10⁻⁸ = \frac{[H_{2}]^2[S_{2}]}{[H_{2}S]^2}

First we <u>calculate the initial concentration</u>:

0.45 molH₂S / 3.0L = 0.15 M

The concentrations at equilibrium would be:

[H₂S] = 0.15 - 2x

[H₂] = 2x

[S₂] = x

We <u>put the data in the Kc expression and solve for x</u>:

\frac{(2x^2) * x}{(0.15-2x)^2}=9.30x10^{-8}

\frac{4x^3}{0.0225-4x^2}=9.30*10^{-8}

We make a simplification because x<<< 0.0225:

\frac{4x^3}{0.0225} =9.30*10^{-8}

x = 8.058x10⁻⁴

[H₂] = 2*x = 1.61x10⁻³ M

Goshia [24]

Answer:

im not completely sure but the mst likely answer would be the would be they have the same density

Explanation:

if two mixture have the same ingriedients their most likely going to have the same density depending of the measurements like when baking a cake when you add your wet ingriedients to your dry one it makes a batter and if you were to make another mixture with the same ingriedients and somewhat similar measurements your going to get a similar density

Se combustionan 2 g de magnesio en Aire, obteniéndose 3,28 g de óxido de magnesio (MgO)¿Qué masa de oxígeno se consumen en la re
konstantin123 [22]

Answer:

1.30 g

Explanation:

La reacción que toma lugar es:

  • 2Mg + O₂ → 2MgO

Primero <u>convertimos 3.28 g de MgO en moles</u>, usando su <em>masa molar</em>:

  • 3.28 g ÷ 40.3 g/mol = 0.081 mol MgO

Después <u>convertimos 0.081 moles de MgO en moles de O₂</u>, usando los <em>coeficientes estequiométricos</em>:

  • 0.081 mol MgO * \frac{1molO_2}{2molMgO} = 0.0407 mol O₂

Finalmente<u> convertimos 0.0407 moles de O₂ en gramos</u>:

  • 0.0407 mol O₂ * 32 g/mol = 1.30 g
