What do elements in the Oxygen Group have in common?

Answers

Answer:

Oxygen is in group 16 in the periodic table.  All the elements in this group have in common the number of valence electrons in their outer shell (6 valence electrons).  The only reason I can see that they may be considered "mixed"  is because the group includes non metals and metalloids.

Explanation:

Answer:

Elements in the Oxygen Group (also called the Chalcogen Group) are all non-metal elements that are located in Group 16 of the periodic table. They include oxygen, sulfur, selenium, tellurium, and polonium. These elements all have similar properties because they have a similar number of valence electrons, which are the electrons in the outermost energy level of an atom. They all also tend to form compounds by gaining two electrons to become negatively charged ions.

(Repost) How would you balance the following chemical equation:
A) Place a 2 in front of Ca2
B) Place a 2 in front of O2
C) Place a 2 in front of CaO
D) It is already balanced

Answers

Answer:

C) Place a 2 in front of CaO

Explanation:

The equation:

Ca2 +O2 → CaO is not balanced as there are 2 atoms of Ca from Ca2 on the left side and there is 1 atom of Ca from CaO on the right side, so add a 2 in front of CaO.

Ca2+O2 → 2CaO

On the left we have:

2 atoms of Ca

2 atoms of O

On the right we have:

2 atoms of Ca

2 atoms of O

The equation is now balanced as there are equal numbers of atoms of each side

C, the reactants have an equal charge so there isn’t a need to have multiple of them. Because there’s two of each, there will we 2 of the product

Which statement Best describes this kind of reproduction?


A. Each parent passes half of it's genes to every offspring
B. all the offspring of a set of parents have identical genes
C. Each parent passed all of it's genes to every offspring
D. Only one parent is required to produce offspring

Answers

Answer:

b

Explanation:

their genetics come from the same two parents so if their genetics looked different it would mean that a offspring wasnt one of the parents.

To solve this, we must know each and every concept behind reproduction. Therefore, all the offspring of a set of parents have identical genes best describes this kind of reproduction. the correct option is option B.

What is reproduction?

The process through which organisms duplicate themselves is known as reproduction. In general, reproduction is among the most essential notions in biology: it involves creating a replica, a likeness, and so ensuring the survival of species.

Their genetics are derived from the exact two parents, thus if their genetics differed, it meant that an offspring was not one of the mom and dad. "All the offspring of a set of parents have identical genes"  best describes this kind of reproduction.

Therefore, all the offspring of a set of parents have identical genes best describes this kind of reproduction. the correct option is option B.
