Add water and you get phosphoric acid
P₂O₃ = diphosphorus trioxide
since there are two phosphorus and three oxygen.
In CaS (Calcium Sulfide), calcium is a metallic element and thus it is rich in valence electron. The outer most shell of CaS consists of two valence electrons, thus it is required to lose two electron to become noble. While sulfur has six valence electron in its outermost shell, thus it is required to gain two electrons to become noble. Thus there is a sharing of two electrons between the two element and therefore its ionic formula is Ca(II)S
D concave pentagon
Because angle J is pointing inwards.
concave = "cave" in
angle IJK > 180
Also diagonal from I to K goes outside of the polygon
geometric shapes equilateral triangle
Equilateral triangles have all angles equal to 60° and all sides equal length.
All equilateral triangles have 3 lines of symmetry.
Isosceles triangles have 2 angles equal and 2 sides of equal length.
All isosceles triangles have a line of symmetry.
Scalene triangles have no angles equal, and no sides of equal length.
right triangle or right angled triangle
Right triangles (or right angled triangles) have one right angle (equal to 90° ).
Obtuse triangles have one obtuse angle (an angle greater than 90° ). The other two angles are acute (less than 90° ).
Acute triangles have all angles acute.

sphere of influence
a sphere of influence is a region upon which an imperial power has considerable intrest,and influence in. It can be achieved through miltary force or diplomatic means. The term became popular during the scramble for and partitition of africa, after the Berlin conference of 1884
spheres of influence is the wright answer
