Answer:
The correct answer is the green light.
Explanation:
Plant themselves have a green color pigment in their leaves called chlorophyll which absorbs visible light.
Pigments absorb mostly the red and blue color light and reflect green light. This the reason why plants appear green to us and least likely to make food. Most of the autotrophs contain this green pigment.
Thus, the correct answer is the green light.
Answer: B
Explanation: Due to urbanization and the rapid development of urban areas, it quickly eradicate places for the wild cats to live thereoff leaving them more susceptible to being hunted by natural predators.
Answer:
A. Based on our results, students who do 1 hour of chores per night
have grades that are on average 0.2 points higher than students
who do no chores.
Explanation:
In a scientific experiment that employs the scientific method, series of steps should be followed. The steps involved in the scientific method include; making an observation/asking a question, formulating a hypothesis, testing the hypothesis, analyzing the result, drawing a conclusion etc.
From this step, we would notice that DRAWING CONCLUSION immediately follows the analysis of result, which means the conclusion is based on the result of the experiment. A conclusion in a scientific experiment should be factual and based on the measured result. It should either reject or accept the hypothesis.
The best representation of a conclusion is A. Based on our results, students who do 1 hour of chores per night have grades that are on average 0.2 points higher than students who do no chores. This statement has a conclusive content unlike other options that still seemed unlikely.
The alkalinity as CaCO3 in mg/L is 108,23
<h3>What is alkalinity?</h3>
Alkalinity is the total measure of substances present in water, capable of neutralizing acids. In other words, it is the amount of substances present in the water that act as a buffer.
With that being said;
Equivalent weight = {molar mass}*{ion charge/oxidation number}
- Molar mass of HCO3- = 61g/mol
- Molar mass of CO3 = 60g/mol
- Molar mass of CaCO3 = 100g/mol
- Eq. cot. of HCO3- = 61g/Eq
- Eq. cot. of CO3 = 30g/Eq
- Eq. cot. of CaCO3 = 50g/Eq
Alkalinity due to CO3 = {32x50}{30} = 53.33mg/L
Alkalinity due to HCO3- = {56x50}{61} = 54,90mg/L
Total Alkalinity = 53,33 + 54,90 = 108,23 mg/L
In this case, we have to The alkalinity as CaCO3 in mg/L is 108,23 mg/L
