The Earth is rhetorically called the world of water. This is because 70 to 71% of the 

Earth surface is occupied with water. Our country the Philippines is surrounded with 

multiple bodies of water, then why is that despite of this, one of leading problem or 

crisis that the most communities are facing is water shortage, how can this be 

possible knowing that there is an abundance of water that surrounds our islands. 

What is the root of this? And What proposition would you suggest in alleviating 

suffering from this crisis?

 Showers, also known as rain showers, have a shorter duration than rain. They tend 

to be quick and come in bursts. It is a common observation that when the sun comes 

out immediately after a rain shower, the puddles formed from the rain dries up faster 

than if it remains cloudy. Explain, on the molecular level, as to why this occurs.

Carbon monoxide gas, CO_(g), is a primary starting material in the synthesis of many organic compounds, including methanol, CH₃OH_(l). At 2000⁰C, K is 6.40x10^-7 for the decomposition of carbon dioxide gas, CO_2(g), into carbon monoxide and oxygen, O_2(g). Calculate the concentrations of all entities at equilibrium if 0.250mol of CO_2(g) is placed in a 1.000L closed container heated to 2000⁰C.

    2CO_2(g) → 2CO_(g) + O_2(g)

Using the general mass of electrons, protons, and neutrons, calculate the exact mass of a Cu-63 isotope. Write the answer in kg.

Gaseous hydrogen has a density of 0.0899 g/L at 0 °C and at 1 atm.  How many liters would you need if you wanted 1.0078 g of hydrogen? 

Study the following equations and identify the oxidized substances, reduced substances, oxidant and reductant.

(a)Fe 2 O 3(s) +3CO \; \ 2Fe (s) +CO 2(g);

(b)SO 2(g) +2H 2 S (g); LH 2 O (l) +3S (s);

(c)C (s) +H 2 O (g) \; CO (g) +H 2(g);

(d)CuO (s) +H 2 (g).; Cu (s) +H 2 O (g); MgO + H (g)

(e)Mg 1c +H 2 O (g)
