A or D I think...sorry if it’s wrong
Answer:
The force applied to the object is an external force, from outside the system. When it does positive work it increases the gravitational potential energy of the system. Because gravitational potential energy depends on relative position, we need a reference level at which to set the potential energy equal to 0.
Answer:
(a) barium chloride : BaCl₂ [the cation is barium and anion chloride]
(b) magnesium-nitride
: Mg₃N₂ [Mg is cation and N anion]
(c) sulfur dioxide
: SO₂ [ S is cation and O anion]
(d) nitrogen trichloride : NCl₃
(e) dinitrogen trioxide
: N₂O₃ [two nitrogens and three oxygen]
(f) tin(IV) chloride : SnCl₄
Explanation:
The formula of a compound comprises of the symbol of all the elements.
The element or ion having positive charge is written first followed by anion.
The number of any element is represented as subscript in the formula.
(a) barium chloride : BaCl₂ [the cation is barium and anion chloride]
(b) magnesium-nitride
: Mg₃N₂ [Mg is cation and N anion]
(c) sulfur dioxide
: SO₂ [ S is cation and O anion]
(d) nitrogen trichloride : NCl₃
(e) dinitrogen trioxide
: N₂O₃ [two nitrogens and three oxygen]
(f) tin(IV) chloride : SnCl₄
Answer:
Is it multiple choice? you didnt have any choices
Explanation:
Democritus was a Greek philosopher who studied natural phenomena and concluded together with his mentor, that all matter is made up of tiny particles he called atoms. The basic tenets of this theory are that atoms are invisible, indestructible, are homogeneous, are solid and differ in shape, mass, size arrangement and postion.
