Phases in the given chemical reaction:
Hydrogen H₂ is in gas (g) phase
Oxygen O₂ is in gas (g) phase.
Water H₂O is in liquid (l) phase.
What is a phase?A phase in thermodynamics that is a chemically and physically homogeneous or homogeneous amount of substance that can be mechanically separated from a heterogeneous mixture and that can consist of a single substance or a mixture of substances. The three basic phases of matter are solid, liquid, and gaseous (vapor), but others are believed to exist, including crystalline, colloidal, glassy, amorphous, and plasma phases. A phase change is said to have occurred when a phase changes from one form to another.
For the given reaction,
H₂(g) + O₂(g) → H₂O(l)
Hydrogen and oxygen are present in gaseous phase, while water is in liquid phase.

what is the reaction between phosphate ion (PO4 3-) and hydronium ion (H3O+)
Answer:
H3O+(aq) + PO43−(aq) ⇌ HPO42−(aq) + H2O(l)
Notice that the total charge (2-) is the same on both sides of the equation, and that this is reaction can take place in both directions.

i hope it helps uh..!!mark me as brainliest ♥️three moles of a monatomic ideal gas undergoes an isochoric process in which the temperature changes from 500 k to 300 k. calculate the change in volume during this process (in m3).
Change in volume is 0 m3 when three moles of a monatomic ideal gas undergoes an isochoric process in which the temperature changes from 500 k to 300 k.
An isochoric process, also known as a constant-volume process, isovolumetric process, or isometric process in thermodynamics, is a thermodynamic process where the volume of the closed system having undergone such a method remains constant.
In everyday life, we see an isochoric process once we boil the water in a pressure cooker. Because the temperature increase is accomplished at a constant volume, we encounter an isovolumetric process when we transfer heat to the container.
In this problem we have T1=500K T2=300K
Since in isochoric process volume in constant, change in volume = 0

how many electrons are gained in a balanced half-reaction in which chlorine gas is reduced to the aqueous chloride ion?
Each chlorine atom acquires an electron during the reaction to create a chloride ion (Cl-), which is the process known as reduction.
What is an example of a redox reaction?A redox reaction is when there is simultaneous oxidation and reduction. CuO+H2→Cu+H2O. Example: In this process, hydrogen is oxidized to water while copper oxide is reduced to copper.
Combination, breakdown, displacement, combustion, and disproportionation are the five primary categories of redox processes.
The definition was eventually expanded to cover additional processes in which electrons are lost, regardless of whether oxygen was present, because it was understood that the material loses electrons when it is oxidized.

What is the formula for cobalt(II) nitride?
Answer:
Co(NO3)2
Explanation:
The chemical formula for cobalt(II) nitride is Co₃N₂ which has 3 and 2 cobalt and nitrogen atoms respectively.
What is chemical formula?Chemical formula is a way of representing the number of atoms present in a compound or molecule.It is written with the help of symbols of elements. It also makes use of brackets and subscripts.
Subscripts are used to denote number of atoms of each element and brackets indicate presence of group of atoms. Chemical formula does not contain words. Chemical formula in the simplest form is called empirical formula.
It is not the same as structural formula and does not have any information regarding structure.It does not provide any information regarding structure of molecule as obtained in structural formula.
There are four types of chemical formula:
1)empirical formula
2) structural formula
3)condensed formula
4)molecular formula
