Answer:
An alloy is the combination of metals homogeneously.
Explanation:
Alloys can also include other elements in combination with metals e.g carbon and Iron forms steel.
Alloys find a host of application in various industries and domestic use.
Alloying of metals helps to improve the physical and chemical properties of such materials better.
Some materials are alloyed to improve their strength.
Alloying can help heat and electrical conduction of a substance.
Alloys can greatly prevent rusting and produce corrosion resistant metals.
Alloys can provide a better means for a material to be worked.
Alloys can be more durable than original materials.
Answer:
"Urban area is used for the buildings, industries etc, whereas the rural areas are used for cultivation, forest cover etc."
Explanation:
When we talk about the urban land they are mostly covered with buildings, industries, roads and apartments and also the municipal structures. But when we talk about the rural land it has less dense population with forest cover, agricultural lands, rangeland and also different land cover type.

Answer:
See explanation.
Explanation:
Hello!
In this case, we can proceed as follows:
1. Here, the undergoing chemical reaction is:
Thus, the moles and mass of water turn out:
2. Here, the undergoing chemical reaction is:
So the required moles of HCl and the yielded of water are:
3. Here, the undergoing chemical reaction is:
Now, we apply each mole ratio obtain:
A.
B.
Best regards!
Divide 180kg and 90m3 and your density will be 2kg/m3
The answer is c)11 because copper has 11 valence electrons
