Explanation:
Given that,
Initial temperature
Final temperature
Length = 34.0 m
We know that,
Coefficient of linear expansion of Invar is
Coefficient of linear expansion of steel is
We need to calculate the temperature difference is
We need to calculate the change in length of Invar
Using formula of change in length
Put the value into the formula
We need to calculate the change in length of steel
Difference in length of two 34.0 m
Long surveyor's tapes is
Put the value into the formula
The difference in length is 18.12 mm.
Hence, This is the required solution.
Answer:
Reactants are initiators of a chemical reaction whereas products are substances produced as the end of that reaction.
Explanation:
In a chemical reaction, there are two categories of substances involved: reactants and products.
The reactants are those substances utilized in a chemical reaction which undergo certain changes to produce different substances at the end of the reaction known as products.
On can write a chemical equation as:
M+N→MN, where M and N are the reactants and MN is the product.
For example,
Zn + S → ZnS
|___| ↓
Reactants Products
As you can notice when writing a chemical equation, reactants are always written on left hand side of the arrow and the products on the right hand side.
