atm for standardized pressure
2 atm is your answer. This is because atm stands for atmosphere which is a unit of pressure.
Chemical reactions are carried out at a certain rate. Sometimes that rate is quite slow, so we want to speed things up, which is usually used by increasing temperature, increasing pressure or adding a catalyst (a substance that increases the rate without changing itself).
If this is the case, then, when writing a chemical equation, we state these special conditions over a right arrow.
Now let's look at the answers:
- 25°C is a value and unit of temperature
- ∆ is a symbol that denotes change
- 2 atm is a value and unit of pressure (atmosphere is old unit for pressure)
- Pt is a chemical symbol for platinum, an element often used as a catalyst.
So, the correct answer is C) 2 atm
Different symbols have different meanings in chemistry. For example, the symbol Δ = adding energy to the reactants.
To identify whether the reactants combine with a specific pressure, we have to use the symbol atm, in such a case 2 atm.
Hope that helps!
2atm symbol can be used to indicate the pressure at which a chemical reaction is carried out
Answer : The symbol used to indicate the pressure at which a chemical reaction is carried out can be, 2 atm.
Chemical reaction : It is defined as the reaction in which the one or more reactants converted to one or more different substances known as product.
The reactants and product are separated by right arrow.
The species present on the left side of the right arrow is the reactant and the species present on the right side of the right arrow is the product.
Some symbols used in the chemical reaction are :
The symbol is used for temperature.
The symbol (s), (l), (g) and (aq) are used for the representation of physical states.
The symbol 'atm' is used for pressure.
Hence, the symbol used to indicate the pressure at which a chemical reaction is carried out can be, 2 atm.
The symbol 'atm' is used for pressure. Hence, the symbol used to indicate the pressure at which a chemical reaction is carried out can be, 2 atm.Aug 18, 2019
