Sodium has more valence electrons than magnesium.
True
False
Correct answers only please, no links. (15 points)
Answer:
False
Explanation:
hi! sodium has one valence electron while magnesium has 2. this is because of their position on the periodic table. sodium is the first in the row, meaning it has one valence electron. magnesium is next to sodium on the periodic table, meaning it is second in the row and has two valence electrons. hope this helps!
a side reaction occurs when acid is added to the system. which species reacts with the acid?
A side reaction occurs when acid is added to the system, so the species reacts with the acid is base.
What are acids?Acids are those species which have a pH range in between 0 to 7, generally acids are present with hydrogen atom in their molecular formula.
If in any reaction after adding the acid, side reaction wiull occur then in this condition base will reacts with the acid as it has the opposite behavior as of acid and formation of salt & water molecules takes plavce.
Hence the needed species is base.

Solve the following problems and show the complete solutions.
1. How many moles of Carbon Dioxide is equivalent to 1.5X1023 atoms of CO2?
2. If you have 5grams of pure Aluminum, (Al), how many atoms does it have? (Al=27)\.
3. If 3 moles Sodium (Na) reacts with exact Chlorine gas (Cl2) in this reaction: 2Na + Cl2 ---> 2NaCl How many mole of Sodium Chloride (NaCl) will be produced?
4. Give the mass percent composition of Potassium, Sulfur and Oxygen in a molecule of Potassium Sulfate: K2SO4.(atomic mass: K=39, S=32).
5. If 162g of Aluminum reacts with 144g of Oxygen gas to form Aluminum oxide, what is the mass percentage of Aluminum?
6. A sample was analyzed and found to contain 40% Carbon. 6.71% Hydrogen and 53.29% Oxygen. If the molecular mass of this compound is 18.16g/mol, what is the empirical and molecular formula of this compound?
The molecular formula of the compound is C6H12O6.
1) We know that;
1 mole of CO2 contains 6.02 X 10^23 atoms
x moles of CO2 contains 1.5 X 10^23 atoms
x = 1 mole X 1.5 X 10^23 atoms /6.02 X 10^23 atoms
x = 0.25 moles of CO2
2) 1 mole of pure Al has 27 g
x moles of Al has 5 g
x = 1 mole × 5 g/ 27 g
x = 0.19 moles
If 1 mole of Al contains 6.02 X 10^23 atoms
0.19 moles of Al contains 0.19 moles × 6.02 X 10^23 atoms /1 mole
= 1.14 X 10^23 atoms
3) From 2Na + Cl2 ---> 2NaCl;
2 moles of Na produces 2 moles of NaCl hence 3 moles of Na will also produce 3 moles of NaCl.
4) The molar mass of K2SO4 is obtained from;
2(39) + 32 + 4(16) = 78 + 32 + 64 = 174 g/mol
Now;
Percentage by mass of K = 2(39)/ 174 × 100/1 = 44.8%
Percentage by mass of S = 32/174 × 100/1 = 18.4%
Percentage by mass of O = 4(16)/174 × 100/1 = 36.8%
5) The reaction equation is;
4Al(s) + 3O2(g) ----> 2Al2O3
Total mass present = 162g + 144g = 306 g
Mass percent of Al = 162g/ 306 g × 100/1 =52.9%

C - 40/12 H - 6.71/1 O - 53.29/16
C - 3.33 H - 6.71 O - 3.33
Dividing through by the lowest ratio
C- 3.33/3.33 H - 6.71/3.33 O - 3.33/3.33
C - 1 H - 2 O - 1
The empirical formula is CH2O
Now;
[12 + 2(1) + 16] n = 180.16
30n = 180.16
n = 180.16/30
n = 6
The molecular formula is C6H12O6.

Which of the following giant covalent structures does not have a high melting and boiling
point?
a) Polythene
b) Graphite
c) Silicon dioxide
d) Diamond
Answer:
Polythene has the lowest melting/boiling point from all the other covalent structures mentioned in this question.
Answer:
Polythene (polyethene according the IUPAC nomenclature.)
Explanation:
Consider the structure of each option:
Polythene: long chains of atoms that are able to rotate along the bonding axis. Graphite: layers of (hexagonal) carbon sheets; each individual sheet is rigid (allows no rotation.) Silicon dioxide: three-dimensional (tetrahedral) network of carbon and oxygen atoms; the entire network very rigid (allows no rotation.)Diamond: three-dimensional (tetrahedral) network of carbon atoms; likewise, the entire tetrahedral network is very rigid.Melting each structure requires overcoming the forces that hold the structure rigid:
In polythene, van der Waal forces hold the chains together and prevents rotations.Deshaping graphite requires bending the layers; doing so would require overcoming the covalent bonds within the hexagonal sheets.In silicon dioxide and diamond, deshaping the tetrahedral network also requires overcoming covalent bonds.Van der Waal forces are much easier to break than covalent bonds.
Hence, the melting point of polythene would be the lowest among the options.

BALANCED EQUATION FOR THE BURNING OF METHANE GAS.
CH₄+2O₂→CO₂+2H₂O
Answer:
170 dm³ (2 significant figures)
Explanation:
CH₄ + 2O₂ → CO₂ + 2H₂O
We need to find how much 'volume' of O₂ is required to burn 56 g of CH₄.
Let's take the ratios of the two gases only.
CH₄ : 2O₂ (in terms of moles the ratio is 1:2)
56g : x dm³
Mr of CH₄ : Volume of oxygen at rtp
Find the Mr of CH₄.
Mr of CH₄ = 12 + (1 × 4) = 16
We know that 1 mole of any gas occupies 24 dm³ at room temperature and pressure (rtp). We have to find the volume of oxygen, there are 2 moles of oxygen, so 2 moles of gas will occupy:
2 × 24 = 48 dm³
56g : x dm³
16 : 48 dm³
16x = 56 × 48
16x = 2688
x = [tex]\frac{2688}{16}[/tex]
x = 168 dm³
∴ the minimum volume of oxygen gas, at room temperature and pressure required to completely burn 56g of methane gas is 170 dm³
