Question

Read the text below and correct the underlined word in each question. Write the correct word in the space provided on your answer sheet. The pandan cake is a very popular dessert among Malaysians. Baking the cake for the first time may be (0) quite an experience but it is not as difficult as you may think. For the ingredients, you need four eggs, (9) with the yolks separated from the whites, a quarter teaspoon of pandan essence, (10) ground pandan juice, 120 grams of flour, 160 grams of fine sugar, and a pinch of salt. Firstly, add the pinch of salt to the egg whites and (11) whisk it until smooth and fluffy. Next, add the fine sugar (12) and continue beating it until white and creamy. In a separate (13) mixing bowl, beat the egg yolks until creamy. Then, slowly add the beaten egg yolks (14) to the mixture of egg whites. Slowly fold in the flour, a little (15) at a time. (16) Initially, add in the pandan juice and pandan essence. Stir the mixture thoroughly and pour it into a baking tray. Bake at 160 degrees Celsius for 30 minutes.

Answer 1

The discussed concepts revolve around conversion factors used in cooking and stoichiometry in chemistry. For a pound cake recipe, equal weights of each main ingredient are required, while in chemistry, a balanced equation dictates the mole ratio of reactants.

Step-by-step explanation:

The question relates to the concept of conversion factors in a mathematical context, specifically within the scope of cooking and baking. When dealing with recipes like the classic pound cake, which requires equal weights of eggs, butter, flour, and sugar, conversion factors are used to maintain the correct proportions of ingredients regardless of the quantity being made. If you have 4 pounds of butter, you also need 4 pounds each of sugar, flour, and eggs to keep the proportions consistent with the original recipe.

Similarly, understanding ratios is crucial in chemistry when interpreting a balanced chemical equation. For instance, in the reaction where hydrogen gas reacts with oxygen gas to produce water, the stoichiometry indicated by the coefficients shows that 2 moles of hydrogen gas react with 1 mole of oxygen gas to produce 2 moles of water. Therefore, if you start with 1.00 g of hydrogen gas (H₂), you'll need to figure out the corresponding amount of oxygen gas needed for the reaction based on the mole ratio.
