A. Objective The learners should be able to investigate changes that happen in the absence of oxygen. B. Materials ● fire. Activity: TITLE: ABSENCE OF OXYGEN Jar with cover (Jar A) Jar without cover (Jar B) 2 same sized candle (small) Match or lighter Timer Ruler C. Precautionary Measure Remember to handle match or lighter carefully and don't play with it for it can cause D. Procedure 1. Label the jar with cover with Jar A and the jar without cover as Jar B. 2. Light the candles with a match and put the candles in each jar. 3. Record the time when the candles are lighted and the time when the light was put off. 4. Cover the Jar A and observe what will happen. 5. Measure the length of the candles after the flame was put off. 6. Record your findings on the chart below. Jars JAR A JAR B Time of the flame was put off Length of the candle after burning Answer the following questions: 1. Which of the 2 jars was the candle's flame put off first? 2. Which of the two candles has the shortest size? 3. What happen, when you cover the Jar A? 4. When the lighted candle in Jar A was covered, the flame was put off, what is the reason why the candle's flame did not continue to burn? 5. What are the 3 main components in combustion? Doss​

ordered pair for the relationship 1) domain 2)range​

Step-by-step explanation:

To provide ordered pairs for a relationship, we need to know the specific relationship or function in question. The domain refers to the set of input values, while the range refers to the set of output values.

For example, let's consider a simple linear function: f(x) = 2x + 3.

In this case, we can determine the ordered pairs by selecting different values for x and evaluating the function to find the corresponding y values.

1) Domain: Let's choose a few values for x: -2, 0, and 3.

- When x = -2, f(-2) = 2(-2) + 3 = -1. So, the ordered pair is (-2, -1).

- When x = 0, f(0) = 2(0) + 3 = 3. The ordered pair is (0, 3).

- When x = 3, f(3) = 2(3) + 3 = 9. The ordered pair is (3, 9).

2) Range: The range consists of the corresponding y-values for the chosen x-values.

- The range for the given function is {-1, 3, 9}.
