Write an If . . . Then statement that tests whether the value in the variable intRow is between 1 and 8. If the number is in that range, set the Text property for the lblCabin Label object to "First Class."

The statement to this question can be described as follows:

Statement:

if (intRow > = 1 && intRow < = 8)

{

lblCabin.Text= “First Class"; //if block that checks the given range and assign the value.

}

Explanation:

Description of the if block:

In the above, If statement fist the value is check, that is it is in the range or not. To check its value an "intRow" variable is used, that checks the value is greater than equal to 1 and less than equal to 8, in between both condition AND operator, that executes when both conditions are true. Inside the if block a label "lblCabin" is used that assigns a value that is "First Class".

answer: when the substance contain the two parts (polar and non-polar) like soap.

explanation:

soap is produced from the basic hydrolysis of ester "saponification", it is considered as a salt of hydrocarbons. the soap molecule contains the two parts: a polar group   (-coo-na+) and a non-polar group (r-hydrocarbon part). the polar group is called the head and the tail is the non-polar group. the polar group is hydrophilic in nature (water loving) and the non-polar group is hydrophobic in nature (water repelling).the polar/non-polar nature of a substance is useful that it can dissolve the non-polar substances by the polar part and also can dissolve the polar substances by the non-polar part. it commonly used in detergents and soaps.
