64g of sulfur dioxide (SO2) contains 32g of oxygen. Calculate how much sulfur it contains?
Answers
⇒ 64 g= mass of sulfur+ 32 g
⇒ mass of sulfur= 64 g-32 g
⇒ mass of sulfur= 32 g.
There is 32 g of sulfur in 64 g of SO2~

The cells of most plants do not have centrioles, although a spindle of fibers is present. Cytokinesis usually, but not always occurs during telophase. The rigid cell wall prevents the formation of cleavage furrow during cytokinesis; instead, a cell plate forms to separate the parent cell into two daughter cells, and a new cell wall forms along the cell plate.
Question 7 options:
Their speeds are the same.
the object with the greater speed has greater kinetic energy
the object greater speed has the lower kinetic energy
the object with the smaller mass has the greater kinetic energy
Answers
Answer: Option (B) is the correct answer.
Explanation:
Kinetic energy is the energy due to the motion of an object.
Mathematically, K.E =
where m = mass
v = velocity
Therefore, an object whose velocity is more will have more kinetic energy.
Thus, we can conclude that out of the given options, the object with the greater speed has greater kinetic energy is true about their kinetic energy.

C) C2H4O
Answers
Answer:
1) C4H8O2 = C2H4O
2) C4H12O4 = CH3O
3) C2H10O2 = CH5O
Explanation:
- The empirical formula is the formula that indicates the relative proportions of the elements in a molecule rather than the actual number of atoms of the elements. It tells us the simplest ratio of elements in a given compound.
- Molecular formula on the other hand tells us the actual number of atoms of each element a compound or a molecules has. Molecular formula is calculated from the empirical formula and the molecular mass of a compound.
Answer:
C₄H₈O₂ = C₂H₄O
C₄H₁₂O₄ = CH₃O
C₂H₁₀O₂ = CH₅O
Explanation:
1) C₄H₈O₂ = C₂H₄O
The smallest subscript is 2. So dividing each subscript by 2 we get,
C₄/₂H₈/₂O₂/₂ = C₂H₄O
2) C₄H₁₂O₄ = CH₃O
The smallest subscript is 4. So dividing each subscript by 4 we get,
C₄/₄H₁₂/₄O₄/₄ = CH₃O
3) C₂H₁₀O₂ = CH₅O
The smallest subscript is 2. So dividing each subscript by 2 we get,
C₂/₂H₁₀/₂O₂/₂ = CH₅O

Explanation:
Final answer:
The most typical ions formed by K, Ca, and S are K+, Ca2+, and S2-, respectively.
Explanation:
The symbol of the ion most typically formed by each of the elements can be determined by looking at their positions on the periodic table and considering their electron configuration.
- K (Potassium): The most typical ion formed by potassium is K+ (Potassium ion). Potassium has one valence electron in its outermost shell, and it tends to lose this electron to form a stable ion.
- Ca (Calcium): The most typical ion formed by calcium is Ca2+ (Calcium ion). Calcium has two valence electrons in its outermost shell, and it tends to lose these electrons to achieve stability.
- S (Sulfur): The most typical ion formed by sulfur is S2- (Sulfide ion). Sulfur has six valence electrons in its outermost shell, and it tends to gain two electrons to achieve stability.
