What is the nutritional value of yellow milk compared to regular white milk?
Yellow milk, also known as flavored milk, typically has added sugars and artificial flavors, which can increase its calorie and sugar content compared to regular white milk. However, the nutritional value of yellow milk can vary depending on the specific brand and ingredients used. In general, white milk is a good source of calcium, protein, and other essential nutrients, while yellow milk may provide similar nutrients but with added sugars and potentially lower nutritional value. It is important to check the nutrition label to compare the specific nutritional content of yellow milk versus white milk.
What is the effect of adding too much acid in milk?
Adding too much acid to milk can cause the proteins in the milk to denature, which can lead to curdling. The acidity can also affect the taste and texture of the milk, making it sour and unpleasant to consume. In addition, excessive acid can also reduce the nutritional value of the milk.

It may be defined as the number of milliliters of 0.1 N alkali solution required to neutralize the volatile, soluble fatty acids distilled from 5 g of fat under specified conditions. It is primarily a measure of butyric acid. The value for milk fat ranges between 17 and 35 and this value is well above that for all other fats and oils.
What is rm value in chromatography?
The rm value (also known as retention factor) in chromatography is a measure of how strongly a compound is retained by the stationary phase relative to the mobile phase. It is calculated as the distance traveled by the compound divided by the distance traveled by the solvent front. The rm value helps in characterizing and identifying compounds based on their behavior in the chromatographic system.
How long does it take a principal of RM 25000 at a simple interest rate of 5 percent to become RM 30000?
4 time periods (eg 4 years if the 5% simple interest were added each year). In simple interest, the interest is added, but attracts no interest itself (that is compound interest) - only the original value attracts the interest: 5% of RM 25000 = RM 1250 added each time RM 30000 - RM 25000 = RM 5000 RM 5000 ÷ RM 1250 = 4 time periods
