Answer: 4 is the subscript in .
Explanation:
We know that,
Subscript: The number of atom present in a given compound.
In , 4 represents the number of chlorine atom in 1 mole of Silicon tetra chloride.
Coefficient: Number of atom which is used in reaction.
For example: In , 3 is the coefficient of silicon tetra chloride.
A Product : In the balance equation, right hand side is called product.
A reactant : In the balance equation, left hand side is called reactant.
For example: the balance equation is
In this equation, is the reactants and
is products.
Hence, 4 is the subscript in .
Answer:
k_max = 31.82 w/mk
k_min = 17.70 w/mk
Explanation:
a) the maximum thermal conductivity is given as
where k_m is thermal conductvitiy of metal
k_p is thermal conductvitiy of carbide
v_m = proportion of metal in the cement = 0.17
v_p = proportion of carbide in the cement = 0.83
= 66*0.17 + 28*0.83
k_max = 31.82 w/mk
b) the minimum thermal conductivity is given as
= \frac{28+66}{28*0.17 +66*0.83}
k_min = 17.70 w/mk
