<h2>                     <u><em> CLIMATE CHANGE</em></u></h2>

Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle. But since the 1800s, human activities have been the main driver of climate change, primarily due to burning fossil fuels like coal, oil, and gas.

Burning fossil fuels generates greenhouse gas emissions that act like a blanket wrapped around the Earth, trapping the sun’s heat and raising temperatures.

Examples of greenhouse gas emissions that are causing climate change include carbon dioxide and methane. These come from using gasoline for driving a car or coal for heating a building, for example. Clearing land and forests can also release carbon dioxide. Landfills for garbage are a major source of methane emissions. Energy, industry, transport, buildings, agriculture, and land use are among the main emitters.

Nowadays the ice is melting more rapidly, this can cause a rise in water/ocean. The forests are drying up faster, species populations are declining rapidly. So we must take action before it is too late.

Thank you.

1. A solution has a volume of 2500 mL. How<br>many liters is this?<br>​
pentagon [3]

The volume of the given solution is 2.5 L.

<u>Explanation:</u>

Volume of the solution = 2500 mL

We have to convert it into litres as,

1000 mL = 1 litre

To convert ml into litres we have to divide the millilitres by 1000, so that it can be converted into L.

Here given volume is 2500 mL.

Volume in L = $\frac{2500}{1000}  

                   = 2.5 L

So the volume of the solution is 2.5 L.

if you take 2.0mL of a 7.0 ppm NaOH solution and dilute it to 250.0mL, calculate the final concentration in ppm.
Oduvanchick [21]

Answer:

C₂ = 0.056 ppm

Explanation:

Given data:

Initial volume = 2.0 mL

Initial concentration = 7.0 ppm

Final volume = 250.0 mL

Final concentration = ?

Solution:

Formula:

C₁V₁ = C₂V₂

C₁ = Initial concentration

V₁ = Initial volume

C₂ = Final concentration

V₂ = Final volume

Now we will put the values in formula.

C₁V₁ = C₂V₂

7.0 ppm × 2.0 mL = C₂ × 250.0 mL

C₂ = 14.0 ppm.mL /250.0 mL

C₂ = 0.056 ppm

Which of the following reactions shows that the formation of CO2 releases
tiny-mole [99]

Answer:

A. C(s) + O2(g) → CO2(g) + 393.5 kJ

Explanation:

The formation of carbon IV oxide (CO2) is an exothermic process. n exothermic process is a chemical process in which heat is evolved. Speaking in lay man's terminology, heat is one of the 'products' of the reaction. This implies that heat is evolved by the process.

The formation of CO2 is always a combustion reaction where heat is evolved or released by the reaction system. Hence the reaction could be shown as;

C(s) + O2(g) → CO2(g) + 393.5 kJ

This implies that 393.5 kJ of energy is released in the reaction in the form of heat. Hence the answer given in the answer box.
