It should be 8 O atoms. 3O atoms in Na2S2O3 and 5O atom in 5H2O. The reason there are 5 O atoms are because the 5 in front of H2O means you multiply each atom in the compound by that number (like the distributive property). The H2 molecule becomes 10 Hydrogen atoms (5*2) and the Oxygen becomes 5 Oxygen atoms (5*1). Then you add the 5O atoms to the 3O atoms which equals 8
What section? I need more info :(
<h2>
Answer:</h2>
Hydroxide ions.
<h2>
Explanation:</h2>
- When base reacts with water they form hydroxide ion.
- For example, NH₃ + H₂O ----------> NH₄⁺ + OH⁻
(Ammonia) (Water) (Ammonium) (Hydroxide ion).
- In case of strong and week base, generally weak bases partially reacts with water to produce hydroxide ions. Whereas strong base completely reacts with water to produce hydroxide ions And the reaction between a strong acid and a strong base produces salt and water and reaction is called neutralization reaction as both acid and base get neutralized.
Result: On reaction of base with water gives hydroxide ion.
Osmium atomic number is 76
Answer:
True for water: a. In a phase diagram the solid-liquid coexistance line has a negative slope. d. the solid is less dense than the liquid. f. the molecules are closest in the liquid phase. g. Higher pressure will cause the solid to become liquid.
True for most other substances: b. In the phase diagram the solid-liquid coexistance line has a positive slope. c. the solid is more dense than the liquid. e. the molecules are closest in the solid phase. h. higher pressure will cause the liquid to become solid.
Explanation:
Liquid water is usually more dense than the solid ice. This is in contrast to most other substances. In addition, the phase diagram of liquid water is different from those of other substances because of the signs of their slopes. The presence of high pressure can change ice to liquid water while for other substances the presence of high pressure will change liquid to solid.
