Answer:

The ice record shows a period in Earth's history when there was an ice age and the global average temperature was

much colder. During this time, the ice record shows the amount of carbon dioxide in the atmosphere decreased, but the

amount of energy from the sun did not change. How did the the total amount of energy in the Earth system change, how

did this change happen, and how did it contribute to the ice age?

Calculate the heat released when 454 grams of steam at 100 degrees C condenses.
sasho [114]
<h3>Answer:</h3>

1026.05 kJ

<h3>Explanation:</h3>
  • The Quantity of heat is calculated by multiplying the mass of a substance by specific heat capacity and the change in temperature.
  • However, condensation takes place at a constant temperature.
  • Therefore, Quantity of heat is calculated by multiplying mass by the latent heat of vaporization.
  • That is; Q = m × Lv

In this case we are given;

Mass of steam as 454 g

To calculate the amount of heat released we must know the value of latent heat of vaporization;

The latent heat of vaporization of steam is 2260 J/g

Therefore;

Heat released, Q = 454 g × 2260 J/g

                             =1026040 Joules

But, 1000 joules = 1 kilo-joules

Thus, Q = 1026.04 kJ

Hence, the amount of heat released is 1026.05 kJ

a stock solution has a concentration of 0.30 m clo2 and is diluted to become a 0.20 m solution with a volume of 0.050 l. what wa
Pavlova-9 [17]

The stock solution has a volume of 0.208L. When diluted, a stock solution with a concentration of 0.30 m clo2 becomes a 0.20 m stock solution with a volume of 0.050.

A three-dimensional space's occupied volume is measured. It is frequently measured numerically with SI-derived units (such the cubic metre and litre) or with other imperial units (such as the gallon, quart, cubic inch). Volume and length are related in how they are defined (cubed).

A highly concentrated stock solution, often prepared as a 10x concentrated solution, can be described as a stock solution since it can be diluted to create a working solution. In order to prepare complex solutions with numerous constituents, stock solutions can also be utilized as a component.

0.3M*v = 0.125M*0.50L

V=0.208L
