1. When carbon dioxide is bubble through a clear solution of calcium hydroxide, a milky solution of calcium carbonate will be formed. The balanced chemical equation for the reaction is as follows:
CO2 + Ca[OH]2 = CaCO3 + H2O.
That is, one mole of carbon dioxide react with one mole of calcium hydroxide to produce one mole each of water and calcium carbonate.
2. An acidic oxide is defined as those compounds of oxygen which react with water to form acids or react with bases to form salts. They are usually oxides of metals or of metals in high oxidation states.
In the chemical equation given in answer 1, one can easily see that carbon dioxide is an acidic oxide because it reacts with calcium hydroxide [which is a base] to produce calcium carbonate, which is a salt.
The change that would cause an increase in the no. of deaths in the little population of wee bug would be:
b). Decrease Greenleaf
c). Increase Furbil
<u>Wee bug Population</u>
- As per the question, the decrease in Greenleaf would result in reduced eatables for the wee bugs.
- While the increase in Furbil would cause a threat to the population of the wee bug.
- As a result, due to decreased food and increased energy storage by Furbils would increase the death of wee bug population.
Thus, <u>options b and c </u>are the correct answers.
Answer:
P SO₂ = 0.06atm
P O₂ = 2.635atm
P SO₃ = 0.53atm
Kp = 29.6
Explanation:
The reaction of Sulfur dioxide and oxygen react to form sulfur trioxide is as follows:
2SO₂(g) + O₂(g) ⇄ 2SO₃(g)
And Kp is defined as:
Where P represents the pressure at equilibrium of each reactant.
If you add, in the first, 0.59atm of SO₂ and 2.9atm of O₂, the equilibrium pressures will be:
P SO₂ = 0.59atm - 2X
P O₂ = 2.9atm - X
P SO₃ = 2X
<em>Where X represents the reaction coordiante.</em>
<em />
As equilibrium pressure of SO₃ is 0.53atm:
0.53atm = 2X
0.265atm = X
Replacing, equilibrium pressures of each species will be:
P SO₂ = 0.59atm - 2×0.265atm
P O₂ = 2.9atm - 0.265atm
P SO₃ = 2×0.265atm
<h3>P SO₂ = 0.06atm</h3><h3>P O₂ = 2.635atm</h3><h3>P SO₃ = 0.53atm</h3><h3 />
And Kp will be:
<h3>Kp = 29.6</h3>
Answer:
An electron will jump to a higher energy level when excited by an external energy gain such as a large heat increase or the presence of an electrical field, or collision with another electron.

Looks to me like C and O are virtually equal and H is double those, so:
CH_20, which is the empirical formula for carbohydrates.
