Answer:
Unit conversion between Rankine and Kelvin is linear.
Unit conversion between degree Celsius and degree Fahrenheit is linear.
Explanation:
Relation between rankine and Kelvin is
So, the plot between Rankine and Kelvin is a straight line with zero intercept and has a slope having value 
.
Relation between degrees Celsius and degrees Fahrenheit is given by
So, the plot between degrees Celsius and degrees Fahrenheit is a straight line with slope 
and negative intercept of 
.
Answer:
1 mole FeCr2/ 1 mole FeCr2O4
Explanation:
We have to write down the equation of the reaction before we can answer the question;
2C(s) + FeCr2O4(s) -------> FeCr2(s) + 2CO2(g)
By inspection of this reaction equation, we can clearly see that the mole ratio of the reactants and products is 2:1:1:2.
Specifically, the ratio of chromites to ferrochrome is 1:1
Hence;
The mole ration required to convert chromites to ferrochrome is;
1 mole FeCr2/ 1 mole FeCr2O4
Answer:
C
Explanation:
The charge on an atom depends on the number of protons and electrons present in it. The protons in an atom are positively charged while electrons have a negative charge. For a neutral atom, the number of protons balances the number of electrons. for a negatively charged atom, the number of electrons is more than the number of protons. for a positively charged atom , the number of protons are more than the number of electrons.
