Question: Does the diagramed chemical equation above obey the Law of
Conservation of Matter?
Answer:
matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.

How does electronegativity change going down and across the periodic table?
Answer:
On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left.

The painkiller, Advil® contains the active ingredient ibuprofen (IB), which has a pKb of
5.20. If the pH of a solution containing a dissolved tablet of Advil® was found to be
8.20, what was the equilibrium concentration (mol/L) of ibuprofen?
IB + H2O ⇀ IBH+ + OH−
A) 3.7 × 10−4
B) 5.5 × 10−5
C) 2.8 × 10−7
D) 4.0 × 10−7
E) 9.2 × 10−7
This problem is providing the basic dissociation constant of ibuprofen (IB) as 5.20, its pH as 8.20 and is requiring the equilibrium concentration of the aforementioned drug by giving the chemical equation at equilibrium it takes place. The obtained result turned out to be D) 4.0 × 10−7 M, according to the following work:
First of all, we set up an equilibrium expression for the given chemical equation at equilibrium, in which water is omitted for it is liquid and just aqueous species are allowed to be included:
[tex]Kb=\frac{[IBH^+][OH^-]}{[IB]}[/tex]
Next, we calculate the concentration of hydroxide ions and the Kb due to the fact that both the pH and pKb were given:
[tex]pOH=14-8.20=5.80[/tex]
[tex][OH^-]=10^{-5.8}=1.585x10^{-6}M[/tex]
[tex]Kb=10^{-5.20}=6.31x10^{-6}[/tex]
Then, since the concentration of these ions equal that of the conjugated acid of the ibuprofen (IBH⁺), we can plug in these and the Kb to obtain:
[tex]6.31x10^{-6}=\frac{(1.585x10^{-6})(1.585x10^{-6})}{[IB]}[/tex]
Finally, we solve for the equilibrium concentration of ibuprofen:
[tex][IB]=\frac{(1.585x10^{-6})(1.585x10^{-6})}{6.31x10^{-6}}=4.0x10^{-7}[/tex]

Determine the mass of O(2-) ions in 3 mol of alumina (Al2O3). Molar mass of O = 16)
Considering the rule of three and molar mass of O, the mass of O²⁻ ions in 3 mol of alumina Al₂O₃ is 96 grams.
By multiplying the number of moles by the subscripts next to each atom, you get the amount of each element present in the compound. IIf the same atom appears more than once in the compound, you must add its amounts.
So, in 1 mole of Al₂O₃, you have 2 ions of O²⁻.
Then you can apply the following rule of three: if 1 mole of the compound contains 2 ions of O²⁻, 3 moles of the compound contains how many ions of O²⁻?
[tex]amount of ions of O^{2-} =\frac{3 moles of Al_{2} O_{3} x2 ions of O^{2-}}{1mole of Al_{2} O_{3} }[/tex]
amount of ions of O²⁻= 6 ions
Being the molar mass of O 16 g/mole, this is the amount of mass that a substance contains in one mole, then the mass of O²⁻ can be calculated as:
6 x 16 g/mole= 96 grams
Finally, the mass of O²⁻ ions in 3 mol of alumina Al₂O₃ is 96 grams.

Calculate the following examples.
1. Ramji conducted an experiment in the field related to the rate of percolation. He observed that it took 30 minutes for 600 ml of water to percolate through the soil. Calculate the rate of percolation per hour.
2. Jigna takes 50g of dry powdered soil in a filter paper and slowly adds water to the soil from a 100 ml fully filled measuring cylinder. When water starts dripping from the filter paper, 60 ml of water is left in the measuring cylinder. Find out the percentage of water absorbed by the soil.
Answer:
12ml per hour and
69% LOL
1) The rate of percolation would be 0.33 ml/s
Percolation rate = volume of water/time
= 600/1800s
= 0.33 ml/s
2) The percentage of water absorbed would be 40%
Percentage of water absorbed = amount absorbed/total water x 100
amount of water absorbed = 100 - 60
= 40 ml
total amount of water = 100 ml
Percentage of water absorbed = 40/100 x 100
= 40%

The particles in a metal are held together by strong __________ bonds. What word describes the type of bond to complete this sentence?
Answer:
metallic
Explanation:
The dislocated electrons moving around the protons create opposite charges with electrostatic attraction between them that are very strong, and are called metallic bonds.
The particles in a metal are held together by strong metallic bonds . The metals forms crystalline solids with highly ordered lattice structure.
What are metals?Metals are electropositive elements. They are rich in electrons and easily donate their electrons with non-metals to form ionic bonds. Metals gain positive charge by losing electrons.
Metals in periodic table are classified as s block elements that are alkali metals and alkaline earth metals and d-block elements that are transition metals.
Metals forms highly ordered crystal lattice 3 D structures in which metal ions negative ions or electrons are bonded by strong intermolecular force called metallic bonds and the free electrons are located in the interstices.
These electrons can delocalize and conduct thermally and electrically.Hence, the bond which hold the particles in a metal is called metallic bond.

Why can the grasses now grow when they couldn’t earlier?
Grasses can grow where they could not earlier because the soil conditions, water volume, or rate of sunlight have evolved.
Each species of plant requires specific conditions to thrive. These conditions include:
Nutrients from the soil.SunlightSpecific amount of water.This implies that if the conditions for a specific species are not provided in terms of sunlight, radiation, and water, the plant will not grow in that specific zone. In the same way, if the conditions of a zone change and they are not suitable for a plant species the plant will grow even if this was not possible before.
This key idea is the reason why some plants including grasses can now grow in zones where they did not exist before. Some of the factors that have contributed to this are:
Fertilization: This provides soils with necessary nutrients.Climate change: This has affected climate patterns, and therefore it can increase or decrease radiation.Irrigation: This increases the amount of water available for plants.Learn more about grass in: https://brainly.com/question/3671945

how many grams of baf2 are dissolved in 75.0 ml of a saturated solution of baf2? ksp = 1.00 x 10-6
Using the solubility product of the saturated solution, the mass of BaF2 dissolved is 0.083 g.
The equation of the reaction is obtained from;
BaF2(s) ⇄ Ba^+(aq) + F^-(aq)
The concentration of the substance can be obtained from the Ksp as follows;
Ksp = [Ba^2+] [2F^-]^2
Ksp = 4x^3
x = ∛Ksp/4
x = ∛ 1.00 x 10-6/4
x = 6.3 x 10^-3 M
Given that;
mass/molar mass = concentration x volume
molar mass = 175 g/mol
concentration = 6.3 x 10^-3 M
volume = 75.0 ml or 0.075 L
Mass = ?
Mass = concentration x volume x molar mass
Mass = 6.3 x 10^-3 M x 0.075 L x 175 g/mol
