6 0

Answer: Option (d) is the correct answer.

Explanation:

A fatty acid is defined as a long chain of hydrocarbons that consists of a carboxylic group, that is, COOH group at the end of the chain.

General formula of a fatty acid is R-(CH_{2})_{n}-COOH where n is mostly an even number in many cases.

Fatty acids are also known as aliphatic monocarboxylic acid.

For example, C_{17}H_{35}COOH is the formula of stearic acid which is a fatty acid.

Thus, we can conclude that a long chain of hydrocarbon bonded to cooh is a fatty acid.

How many calories of heat are necessary to raise the temperature of 319.5 g of water from 35.7 °C
rjkz [21]

20600Cal              

Explanation:

Given parameters:

Mass of water = 319.5g

Initial temperature = 35.7°C

Final temperature = 100°C

Unknown:

Calories needed to heat the water = ?

Solution:

The calories is the amount of heat added to the water. This can be determined using;

     H  =   m  c Ф

c  = specific heat capacity of water = 4.186J/g°C

   H is the amount of heat

    Ф is the change in temperature

    H = m c (Ф₂ - Ф₁)

    H = 319.5 x 4.186 x (100 - 35.7) = 85996.56J

Now;

     1kilocalorie = 4184J

     

85996.56J to kCal; \frac{85996.56}{4184}   = 20.6kCal  = 20600Cal

What is the formula for the compound by calcium ions and chloride ions?
dimaraw [331]
To find the ratio of the the combination for the ion, write the charge of the cation as the subscript for the anion, and the charge of the anion as the subscript of the cation. This will make the charges effectively cancel and you will be left with a neutral ionic compound. Remember, that an ionic compound is made up of a metal and a nonmetal.
For Ca2+ and Cl-, you will get the neutral compound to be CaCl₂.
