Answer:

223.5 g

Explanation:

The formula between the number of moles, mass and Mr can be used to convert moles to grams.

Number of moles = mass ÷ Mr

So, mass = number of moles × Mr

Mr of Li₂O = (6.9 × 2) + 16 = 29.8

∴ Mass = 7.5 × 29.8 = 223.5 g

A reaction mixture that consisted of 0.35 molH2and 1.6 mol I2 was introduced into a 2 L flask and heated. At the equilibrium, 60

Ann [662]

Answer:

The equilibrium constant Kc for the reaction is :

16.07

Explanation:

The balanced equation is :

$H_{2}(g)+I_{2}(g)\rightleftharpoons 2HI(g)$

First ,

"At the equilibrium, 60% of the hydrogen gas had reacted"

This means the degree of dissociation = 60% = 0.6

Here we are denoting degree of dissociation by ="x" = 0.6

Now , consider the equation again,

$H_{2}(g)+I_{2}(g)\rightleftharpoons 2HI(g)$

H2 I2 2HI

0.35 1.6 0 (Initial Concentration)

0.35(1 - x) 1.6(1 - x) 2x (At equilibrium)

0.35(1 - 0.6) 1.6(1 - 0.6) 2(0.6)

0.14 0.64 1.2

calculate the concentration of each:

$Concentration =\frac{moles}{Volume(L)}$

$C_{H_{2}}=\frac{0.14}{2}$

$C_{H_{2}}=0.07moles/L$

$C_{I_{2}}=\frac{0.64}{2}$

$C_{I_{2}}=0.32moles/L$

$HI=\frac{1.2}{2}$

$HI=0.6moles/L$

The equilibrium constant for this reaction "Kc" can be written as:

$Kc=\frac{[HI]^{2}}{[H_{2}][I_{2}]}$

$Kc=\frac{0.6^{2}}{0.07\times 0.32}$

$Kc=\frac{0.36}{0.0224}$

$Kc=16.07$

A piece of lead loses 78.0 J ofheat and experiences a decrease in temperature of 9.0C the specific heat of lead is .130J/gC what

Ratling [72]

The mass of the piece of lead is calculated using the below formula
Q(heat)= mC delta T

Q = 78.0 j
M=mass =?
C=specific heat capacity ( 0.130 j/g/c
delat T=change in temperature = 9.0 c

by making M the subject of the formula
M = Q/ c delta T

M= 78.0 j/ 0.130 j/g/c x 9.0 c = 66.7 g of lead

E. H2CrO4 + Sr(OH)2 →

katrin2010 [14]

Answer:

The answer to your question is SrCrO₄ + H₂O

Explanation:

Data

H₂CrO₄ + Sr(OH)₂ ⇒

We can notice that this is a Redox reaction or neutralization reaction because the reactants are an acid (H₂CrO₄) and a base (Sr(OH)₂). These reactions are also called double displacement reactions.

In these kind of reactions the products are always a binary or ternary salt and water.

Then, for this reaction,

H₂CrO₄ + Sr(OH)₂ ⇒ SrCrO₄ + H₂O
