This would be the Melting point because it is showing that at a certain heat it melts so therefore it is the point it melts and therefore called the melting point
Answer:
Rock
Explanation:
Rock -
It refers to the naturally occuring mass of mineral , with a uniform chemical composition , is referred to as a rock .
In the crust of the Earth , the composition is by the igneous rocks .
<u>There are three main type of rocks , i.e. , </u>
- sedimentary rocks ,
- metamorphic rocks ,
- igneous rocks .
Hence , from the given information of the question ,
The correct term is rock.
Answer. C. The sample will mainly consist of granite.
Explanation:
Sample collected from was continental crust (a part crust) as the samples were from 60 km deep. Continental crust ranges from 30 km to 70 km and this layer is mainly includes granite. This continental crusts is mainly responsible for formation of distinct land-forms like continents.
Statement A ,B and D informs us about the state and temperature of metals(iron) in core that is inner most layer of the earth.
Answer:
113.4g of N2
Explanation:
Step 1:
The balanced equation for the reaction.
N2 + 3H2 —> 2NH3
Step 2:
Determination of the mass of N2 and H2 that reacted from the balanced equation. This is illustrated below:
Molar mass of N2 = 2x14 = 28g/mol
Mass of N2 from the balanced equation = 1 x 28 = 28g
Molar mass of H2 = 2x1 = 2g/mol
Mass of H2 from the balanced equation = 3 x 2 = 6g
From the balanced equation above, 28g of N2 reacted with 6g of H2.
Step 3:
Determination of the mass N2 required to react with 24.3g of H2.
The mass of N2 required to react with 24.3g of H2 can be obtained as follow:
From the balanced equation above, 28g of N2 reacted with 6g of H2.
Therefore, Xg of N2 will react 24.3g of H2 i.e
Xg of N2 = (28 x 24.3)/6
Xg of N2 = 113.4g
Therefore, 113.4g of N2 is required to react completely with 24.3g of H2.
