The state of matter with a specific volume but no definite shape is the <u>Liquid</u> state.
<u>Explanation:</u>
There are three states of matter according to chemical science: Solid, Liquid and Gas. There is not much space in among the molecules. The particles in a liquid are free to float, so while a liquid has a certain volume it has no definite form. Liquids are composed of atoms or molecules bound by inter molecular bonds.
Most of the liquids resist compression while some do not, unlike a gas, a liquid will not spread to fill any container room and will retain a fairly constant density. A characteristic liquid state property is surface tension that results to wetting phenomena. Water is perhaps the most frequent substance on Earth.
It has a positive charge of 1
Answer:
1533.6 kg NO
Explanation:
The reaction that takes place is:
First we <u>convert the masses of ammonia (NH₃) and oxygen gas (O₂) into moles</u>, using<em> their respective molar masses</em>:
- NH₃ ⇒ 869 kg ÷ 17 kg/kmol = 51.12 kmol NH₃
- O₂ ⇒ 2480 kg ÷ 32 kg/kmol = 77.5 kmol O₂
77.5 kmol of O₂ would react completely with (77.5 kmol O₂ * ) 62 kmol of NH₃. There are not as many kmol of NH₃, so NH₃ is the limiting reactant.
Now we <u>calculate how many kmol of NO are produced</u>, using the <em>limiting reactant moles</em>:
- 51.12 kmol NH₃ * = 51.12 kmol NO
Finally we <u>convert kmol of NO to mass</u>, using its<em> molar mass</em>:
- 51.12 kmol NO * 30 kg/kmol = 1533.6 kg NO
<h3><u>Answer and explanation</u>;</h3>
- Zinc metal reacts with strong bases forming <u>hydrogen gas</u>:
Zn(s) + 2 OH−(aq) → Zn(OH)2(s) + H2(g)
- Zn2+ is precipitated by hydroxide ions as Zn(OH)2 (white amorphous precipitate)
Zn2+(aq) + 2 OH−(aq) ⇄ Zn(OH)2 (s)
- By acid excess hydroxide ions, the precipitate is dissolved.
Zn(OH)2(s) + 2 H+(aq) ⇄ Zn2+(aq) + 2 H2O(l)
Zn(OH)2(s) + 2 OH−(aq) ⇄ [Zn(OH)4]2−(aq)
- [Zn(OH)4]2−(aq)
is the <em>complex ion</em>
When Ag+ is combined with Na2CO3, the substances formed are Ag2CO3 and Na+. In this case, Ag performs single substitution over the element Na to form another set of substances. There are other types of reactions like double displacement, decomposition, etc.
