Answer:
bent
Explanation:
The molecular formula of sulfur dioxide is written as SO₂
The molecular geometry of sulfur dioxide can be determined using the Lewis structure.
The Lewis structure shows the distribution of electrons around the atoms of a given compound such as sulfur dioxide (SO₂).
In this compound, sulfur is the central atom with 6 valence electrons.
The sulfur is bonded covalently with two oxygen atoms, each with 6 valence electrons. Oxygen contributes 2 lone pairs while sulfur which is the central atom contributes 1 lone pair of electrons in the bond.
The bond angle between the two oxygen atoms and the central sulfur atom is approximately 120⁰, as a result of the bent shape of the molecular structure.
Answer:
22g
Explanation:
Given parameters:
Mass of element A = 18g
Mass of element B = 4g
Unknown:
Mass of compound formed = ?
Solution:
The reaction equation is given as;
A + B → AB
According to the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed but changed from one form to another".
Simply mas is conserved and the mass of the reactants is the same as the mass of the product that forms.
Mass of reactants = mass of A + mass of B = 18g + 4g = 22g
So;
Mass of product AB = 22g
well, without the article, I'm guessing the main idea is about the Great Wall of China
A scientific law is a statement based on repeated experimental observations that describes some aspects of the universe. A scientific law always applies under the same conditions, and implies that there is a causal relationship involving its elements.
