Answer:
82.04g
Explanation:
To solve this problem, you need to find the molar mass of HCl, which is the sum of the molar mass of H plus the molar mass of Cl. The molar mass of H is 1.008g/mol while the molar mass of Cl is 35.45g/mol. Thusly the molar mass of HCl is 36.458g/mol. You have 2.25 moles of HCl, so multiply the number of moles by the molar mass to get the mass in g. In this case it is 2.25mol * 36.458g/mol = 82.04g.

Answer: Oxygen
Explanation:
As seen from the balanced equation:
2 moles of hydrogen combine with 1 mole of oxygen or 1 mole of hydrogen combine with 1/2 mole of oxygen.
According to Avogadro's law, equal volumes of gases contain equal number of molecules and hence equal number of moles.
Thus if x moles of both gases are present, x moles of hydrogen will combine with 
moles of oxygen and 
moles of oxygen will be left used and will be in excess.
Answer: Tadpole, also called polliwog, aquatic larval stage of frogs and toads. Compared with the larvae of salamanders, tadpoles have short, oval bodies, with broad tails, small mouths, and no external gills. The internal gills are concealed by a covering known as an operculum.
Explanation:
The answer is a bonding agent
Gases
Explanation:
Gases are the highly compressible states of matter made up of tiny particles that are moving independently of one another and are present in large quantities on the earth surface.
There are three states of matter which are solid, liquid and gas.
- The particles of a gas are very far apart and are held together by very weak attractive forces.
- In a gas, the molecules are in continuous, random, straight -line motion
- They are easily compressible due to the weak attraction between them.
