In a chemical reaction two gases combine to form a solid What do you expect for the sign of S?

the sign of S would be negative because a solid is much more ordered than a gas, and at least 2 moles of gas are forming 1 mole of solid which is even more ordered

What is made up of hydrogen and helium?
No chemical reaction will be there. It is just a mixture of two gases.
What is a violent expansion of gases and release of energy resulting from a rapid chemical reaction?
1or 2
What type of chemical reaction takes place when ammonia and hydrogen chloride gases are mixed and write a chemical equation of this?
NH3(g) + HCl(g) ==> NH4Cl(s). This type of reaction is called "synthesis". The two gases react to form a solid ammonium chloride salt.
What are the two gases those do not take part in chemical reaction?
All Nobel gases very rarely react, they are very stable gases as they have a full outer orbital. (on the far right of the table)
What affects how fast a chemical reaction takes place?
The nature of the reactants, the temperature (and pressure if gases are involved), and the presence of a catalyst.
What is the formed when two gases mix together?
- A mixture of gases- A chemical reaction producing a compound
Where are products found in a chemical reactions?
These products are the result of the chemical reaction. They may be gases, solid precipitates etc.
Is convection a chemical reaction?
no it is a type of conduction that can happen in liquids and gases, conduction happens in solids, and radiation happens in gases
How does pressure speed up a chemical reaction?
Increasing the pressure on a reaction involving reacting gases increases the rate of reaction. Changing the pressure on a reaction which involves solids or liquids has no effect on the rate of reaction.
What is made up of hydrogen and helium?
No chemical reaction will be there. It is just a mixture of two gases.
What is the scientific word for a gas given off during a chemical reaction?
A reaction that emmits heat is called an exothermic reaction .
What is the chemical compound of a fart?
Those have nothing to do with each other. Smelling is something your body does to take in orders, and a chemical reaction is a reaction that cannot be reversed. Thus, smelling does not have anything to do with a chemical reaction.
What is a violent expansion of gases and release of energy resulting from a rapid chemical reaction?

How is gas formed and why is it bad?
A gas may be the product of a chemical reaction. Not all gases are bad.
How does increasing pressure affect the reaction rate?
The concentration of reactants is changed.
