Answer

The base is Ba(OH)2

Explanation

This equation follows the path of, acid +base---salt +water

H2S +Ba(OH)2------BaS +2H2O

Where H2S is the acid, Ba(OH) is the base and 2H2O is water.

Here, Barium hydroxide reacts with hydrogen sulfide to give barium sulfide and water.

A sample of helium occupies a volume of 180.0 ml at a pressure of 0.800 atm and a temperature of 29°C. What will be the
Brrunno [24]

Answer:

If the volume of the container is decreased to  90.0 ml and the pressure is increased to 1.60 atm the temperature will be 302 °K

Explanation:

Boyle's law says that "The volume occupied by a given gas mass at constant temperature is inversely proportional to the pressure", which is expressed mathematically as:  

P * V = k

Charles's Law consists of the relationship between the volume and temperature of a certain amount of ideal gas, which is maintained at a constant pressure, by means of a proportionality constant that is applied directly. In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the ratio between volume and temperature will always have the same value:

\frac{V}{T} =k

Finally, Gay Lussac's law establishes that as the temperature increases, the gas molecules move more quickly and therefore the number of collisions against the walls increases, that is, the pressure increases since the container is of fixed walls and its volume can not change. Therefore, the ratio of pressure to temperature always has the same value (it is constant).

\frac{P}{T}=k

Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law:

\frac{P*V}{T}=k

Having a state 1 at the beginning and a state 2 at the end is fulfilled:

\frac{P1*V1}{T1}=\frac{P2*V2}{T2}

In this case, you know:

  • P1= 0.800 atm
  • V1= 180 mL= 0.180 L (being 1 L=1000 mL)
  • T1= 29 °C= 302 °K
  • P2= 1.60 atm
  • V2= 90 mL= 0.09 L
  • T2=?

Replacing:

\frac{0.800 atm*0.180L}{302 K}=\frac{1.60 atm*0.09L}{T2}

Solving:

T2*\frac{0.800 atm*0.180L}{302 K}=1.60 atm*0.09L

T2=\frac{1.60 atm*0.09L}{\frac{0.800 atm*0.180L}{302 K}}

T2= 302 °K

<em><u>If the volume of the container is decreased to  90.0 ml and the pressure is increased to 1.60 atm the temperature will be 302 °K</u></em>

If you burn 10 kilograms of wood in a fire (combustion) what is the weight of the products after the fire has finished burning t
sleet_krkn [62]

The answer is: the weight of products is is equal the weight of the wood plus the weight of oxygen that was used to burn that wood, so weigh of the product is greater than 10 kilograms.

Conservation of mass (mass is never lost or gained in chemical reactions), during chemical reaction no particles are created or destroyed, the atoms are rearranged from the reactants to the products.

In this example wood (mostly carbon) and oxygen are reactants and carbon dioxide (mostly) is product of reaction.
