The definition in Volume is a the amount of space a substance or object occupies, or that is enclosed within a container, especially when great. For example "The sewer could not cope with the volume of rainwater" . You can say it in different ways, such as capacity, size, magnitude, mass, bulk, extent and more. I hope this helps :-).
Answer:

Explanation:
From the question we are told that:
Mass of zinc 
Initial conc of HCl 
Initial volume of HCl
Molar mass of zinc
Generally the equation for reaction is mathematically given by

Generally the equation for moles of zinc
is mathematically given by



Generally the equation for moles of
is mathematically given by
Generally the reacted moles of HCl
is mathematically given by
Since
Zn:HCl =1:2
Therefore
![HCl_[reacted]=0.038*\frac{2}{1}](https://tex.z-dn.net/?f=HCl_%5Breacted%5D%3D0.038%2A%5Cfrac%7B2%7D%7B1%7D)
![HCl_[reacted]=0.076mol \ HCl](https://tex.z-dn.net/?f=HCl_%5Breacted%5D%3D0.076mol%20%5C%20HCl)
Generally the moles of HCl after Zn oxidization X is mathematically given by


Generally the conc of hydrochloride acid X is mathematically given by


Therefore Conc of HCl

The two main types of weathering are physical and chemical weathering
Answer: transfer of heat by the actual movement of warmed matter
Explanation: convection is the process of heat transfer through fluids. When molecules absorbs heat they become excited and less dense causing it to rise.
Apples turn brown when exposed to air because it undergoes aerial oxidation. Due to this, when the inside of the apple is exposed to the air containing oxygen and water, it turns brown. When apple is uncut, skin of the apple protects it from this process.
If the peeled apple in kept in the refrigerator, the oxidation reaction is greatly slowed down. This is because, rate of chemical reaction decreases with temperature. Hence, in refrigerator it would take several days for it to turn brown.
