The answer to this question would be: decrease
If the process is releasing heat to the surrounding, that means it should be an exothermic process. In the exothermic process, the process enthalpy difference will be minus because some of the energy is released as heat. That means the enthalpy of the system will be decreased.
The correct answer is voltage.
According to ohm's law,
V = IR, where V is the potential difference between two points(voltage), I is the electricity, R is resistance.
If the resistance in the electrical conductor is kept constant then the current in the circuit can be increased by increasing the voltage.
Answer:
5 g of H₂ are contained in the vessel
Explanation:
A typical excersise of conversion:
We determine molar mass of H₂.
This is a dyatomic molecule, as molar mass of H is 1g/mol, molar mass of H₂ will be 2g/mol.
Let's make the conversion of units:
2.5 mol . 2g/mol = 5 g
5 g of H₂ are contained in the vessel
Combustion is a type of exothermic chemical reaction that generates light and heat in most cases, and occurs fairly quickly.
<h3>What is an exothermic reaction?</h3>
An exothermic reaction is one that when it occurs releases energy in the form of heat or light to the environment.
<h3>Characteristics of an exothermic reaction</h3>
- When this type of reaction occurs, the products obtained have lower energy than the initial reactants.
- Most of the exothermic reactions are oxidation, and when they are very violent they can generate fire, as in combustion.
- Combustion is a very fast oxidation reaction that occurs between materials called fuels and oxygen.
Therefore, we can conclude that combustion is an example of an exothermic reaction that releases large amounts of heat, which can lead to fire.
