The  volume  of  0.160    m   Li2S  solution  required  to  completely  react  with  130 ml  of 0.160  CO(NO3)2  is calculated   as  below

write the  reacting  equation

Co(NO3)2 +  Li2S = 2LiNO3  +  COS

find the    moles  of CO(NO3)2  = molarity  x  volume

=  130 ml  x  0.160=20.8  moles

since the reacting moles between CO(NO3)2  to LiS  is   1:1  the  moles of LiS  is  also  20.8  moles

volume  of Lis  is  therefore =  moles of Lis/ molarity  of LiS

=  20.8/0.160 =  130 Ml

30 Pointss<br> Please make sure it is correct please
Vsevolod [243]

Answer:

Option C is correct.

Explanation:

The graph shows birth and death rate in Japan. Birth rate has declined with the passage of time, as shown in the form of blue line whereas death rate is nearly constant, which can be seen as red line. More precisely, birth rate has decreased from ~30 to 10 whereas death rate is nearly ~10 all the times, although it was slightly decreased in the middle. Therefore, option C is the correct option...

Wood has a density of 0.531 g/cm3. What is the volume of 44 grams of wood?
Sunny_sXe [5.5K]

Answer:

<h3>The answer is 82.86 cm³</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}  \\

From the question

mass of wood = 44 g

density = 0.531 g/cm³

It's volume is

volume =  \frac{44}{0.531}  \\  = 82.86252354...

We have the final answer as

<h3>82.86 cm³</h3>

Hope this helps you

We can achieve equilibrium state, when the concentration of product and reactants are equal to each other.

<h3>Describe this system when it reaches phase equilibrium?</h3>

In this type of system, when the same amount of liquid water is converted into gaseous form of water and the gaseous form of water into liquid form of water. This phase is known as equilibrium phase or state because same amount of reactants and products are produced .

So we can conclude that we can achieve equilibrium state, when the concentration of product and reactants are equal to each other.
