If you had a mixture that was found to contain 1.05g SiO2, 0.69g Cellulose and 1.82g Calcium Carbonate. What percentage calcium

boyakko [2]

Percentage by mass = (mass of substance / total mass) x 100
= 1.82 / (1.05 + 0.69 + 1.82) x 100
= 51.1% if Calcium Carbonate

Why is it important to have the correct bond angles of the different atoms and the shape of the molecule? (20 points NEED ANSWER

hjlf

It is important to have the correct bond angles of the different atoms and the shape of the molecule due to following reasons;

Among other properties the polarity of compounds mainly depend upon the shape and bond angles of that particular compound. For example, considering the molecule of water, we already know that it is a polar molecule with partially positive hydrogen atoms and partially negative oxygen atoms and acts as universal solvent. The bond angle in water is about 104.5° with a Bent geometry. Unlike carbon dioxide (CO₂) which has Linear structure with bond angle 180° and is non-polar in nature therefore, the bent geometry in water is responsible for the polarity.

Other properties which can also be predicted by predicting the bond angles along with molecular geometries are;

i) Magnetism

ii) Phase of matter

iii) Color

iv) Reactivity

v) Biological activities e.t.c

Answer:

5.702 mol K₂SO₄

General Formulas and Concepts:

Stoichiometry

Using Dimensional Analysis

Explanation:

Step 1: Define

[Given] 993.6 g K₂SO₄

[Solve] moles K₂SO₄

Step 2: Identify Conversions

[PT] Molar Mass of K: 39.10 g/mol

[PT] Molar Mass of S: 32.07 g/mol

[PT] Molar mass of O: 16.00 g/mol

Molar Mass of K₂SO₄: 2(39.10) + 32.07 + 4(16.00) = 174.27 g/mol

Step 3: Convert

[DA] Set up: $\displaystyle 993.6 \ g \ K_2SO_4(\frac{1 \ mol \ K_2SO_4}{174.27 \ g \ K_2SO_4})$
[DA] Divide [Cancel out units]: $\displaystyle 5.7015 \ mol \ K_2SO_4$

Step 4: Check

Follow sig fig rules and round. We are given 4 sig figs.

5.7015 mol K₂SO₄ ≈ 5.702 mol K₂SO₄
