Oxygen. Is the correct answer
Oxygen has the same number of valence electrons as sulfur. An ion can be an element that gained or lost an electron.
First of all there nothing exists something like SSA congruence criterion, It is SAS Congruence where the sides of a Triangle and the angle between them is exactly same to the other two sides and angle between them of another triangle.
So the correct option is D.
Explanation:
If the Triangle has two sides equal, so the two angles there are equal. Also the other angle be some other definite angle. So
45+x+x=180(Considering definite angle to be 45)
2x=135
x=67.5
So there is only one solution to the triangle.
Answer:
D
Explanation:
Respiration is the process by which you get energy from food. So energy in food is converted to a form that can be used by the body
Answer:
