Write a code block to encode strings from original messages, using our custom encoding. To do so: Initialize a variable called custom_encoded as an empty string Use a for loop to loop across all characters of a presumed string variable called custom_message Inside the loop, check if the current character is in the custom_encodings dictionary If it is, use the current char to get the value from custom_encodings, and concatenate it to custom_encoded The line inside the if should look something like out = out + dictionary[char] Otherwise, concatenate the current character to custom_encoded

custom_encoded = "" custom_message = "this is a pen" custom_encoding = {    "a": "1",    "e": "2",    "i": "3",    "o": "4",    "u": "5" } for c in custom_message:    if(c in custom_encoding):        custom_encoded = custom_encoded + custom_encoding[c]    else:        custom_encoded = custom_encoded + c print(custom_encoded)

Explanation:

The solution code is written in Python 3.

Let's define a variable custom_encoded with an empty string (Line 1).

Create another variable custom_message and set a sample string to it (Line 2).

Create one more variable custom_encoding to hold the mapping values between vowel and their respective encoded character (Line 3-9).

Create a for loop to loop through all the character in custom_message (Line 11) and in the loop check if the current character is found in custom_encoding dictionary, if so, use the current character to loop up the dictionary for the encoded value and add the encoded string to custom_encoded (Line 12-13). Otherwise, just add the current character to custom_encoded (Line 14-15).

At the end, print the custom_encoded to terminal and you shall get th3s 3s 1 p2n

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.
