The "calorie" used to measure the caloric content of foods is actually a kilocaloric (kcal) or 4184kJ. If the heat of cumbustion for sugar Is 5639kJ/Mol, why are people who are on limited calorie diets advised to limit thier fat intake?
Answers
Answer:
fat has twice the calories of carbohydrates per gram
Explanation:
The first point that we must make is that fat has twice the calories of carbohydrates per gram. This is why it is necessary for people who are dieting to limit their intake of fat. It is known that the calories contained in food are obtained from carbohydrates, proteins, and fats. Experts are of the opinion that one gram of carbohydrate contains 4 calories, one gram of protein contains 4 calories while one gram of fat contains about 9 calories. This is a little above two times the amount of calories in carbohydrates and proteins.
Since fat has twice as much calories as carbohydrates or sugar, taking them into the body will increase the 'calories' in the body thereby making the weight loss process difficult since the excess calories will now be stored in the body.
This is the reason why people who are on limited calorie diets are advised to limit their fat intake.
The reason why people who are on limited calorie diets are advised to limit their fat intake: because too much fat can raise the cholesterol level.
A calorie can be defined as a standard unit which is used for the measurement of the energy contained in a food.
Basically, the standard unit for the measurement of the caloric content in food is actually a kiloJoules (kJ) or kilocaloric (kcal).
A limited calorie diet is also referred to as a fat-restricted diet and it refers to an eating plan that completely limits the amount of fat that a person consumes on a daily basis.
Generally, people who are on limited calorie diets are advised to limit their fat intake because too much fat can raise the cholesterol level, which in turn increases their risk of having a heart disease.

Snowshoe hares have fur that changes color in fall and spring. This color change is caused by a genetic trait. In the fall, their fur becomes white, the color of winter snow. In the spring, their fur becomes mostly brown, matching their summertime surroundings. This change is not related to the outside temperature. Instead, it is related to change in the lengths of days and nights. The days get shorter in the fall. They get longer again in the spring. But hares don't all have the same genes. Different individuals change color at different times in fall and spring.

Which of the following best explains the relationship between peak-to-peak amplitude and semi-amplitude?
Answers
Answer:
A. Semi-amplitude is half the distance of the peak-to-peak amplitude
Explanation:
The correct answer is : The semi-amplitude is half the distance of the peak-to-peak amplitude (option A). The peak-to-peak amplitude is the total distance between the highest positive peak and the lowest negative peak in a waveform. It represents the full range of variation in the amplitude of the waveform.
The peak-to-peak amplitude of a waveform is the measurement of the total distance between the highest positive peak and the lowest negative peak. It provides information about the full range of variations in the amplitude of the waveform. Mathematically, it is calculated by subtracting the minimum value from the maximum value of the waveform.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

this is the question and i dont know which reasoning i should use for the claim "If you follow the instructions, the POW kits will always heat the water above the correct temperature for pasteurization (65°C), but some people didn’t follow the instructions."
Answers
Answer:
I think this evidence supports this claim because Evidence Card b says “One man got sick, but his two children did not. He used water from Whip River. He used the cube to heat the first pitcher of water, which he gave to his kids, and then reused the cube without reheating for the second pitcher, which he drank himself.”
Explanation:
The correct reasoning for the given claim is shown by evidence 2.
What is water pasteurization?
Pasteurization is a method of disinfecting water without boiling it using heat or radiation.
Evidence 2 is the correct reasoning to explain the fact that if we follow the instructions the kit will always heat the water above the correct temperature for pasteurization (65°C). Second evidence is that “One man got sick, but his two children did not. He used water from Whip River. He used the cube to heat the first pitcher of water, which he gave to his kids, and then reused the cube without reheating for the second pitcher, which he drank himself.”
Hence evidence 2 is the correct reasoning.

Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element. At standard conditions hydrogen is a gas of diatomic molecules having the formula H2. It is colorless, odorless, non-toxic, and highly combustible. Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all normal matter.[8][note 1] Stars such as the Sun are mainly composed of hydrogen in the plasma state. Most of the hydrogen on Earth exists in molecular forms such as water and organic compounds. For the most common isotope of hydrogen (symbol 1H) each atom has one proton, one electron, and no neutrons.
In the early universe, the formation of protons, the nuclei of hydrogen, occurred during the first second after the Big Bang. The emergence of neutral hydrogen atoms throughout the universe occurred about 370,000 years later during the recombination epoch, when the plasma had cooled enough for electrons to remain bound to protons.[9]
Hydrogen is nonmetallic, except at extremely high pressures, and readily forms a single covalent bond with most nonmetallic elements, forming compounds such as water and nearly all organic compounds. Hydrogen plays a particularly important role in acid–base reactions because these reactions usually involve the exchange of protons between soluble molecules. In ionic compounds, hydrogen can take the form of a negative charge (i.e., anion) where it is known as a hydride, or as a positively charged (i.e., cation) species denoted by the symbol H+. The H+ cation is simply a proton (symbol p) but its behavior in aqueous solutions and in ionic compounds involves screening of its electric charge by nearby polar molecules or anions. Because hydrogen is the only neutral atom for which the Schrödinger equation can be solved analytically,[10] the study of its energetics and chemical bonding has played a key role in the development of quantum mechanics.

When a chemical reaction does not occur, what happens to the atoms of the two substances? Provide an example from Sim as evidence to support your answer.
Answers
An example of this can be seen in the Sim on Amplify, where students can experiment with different chemical reactions. For instance, in the "Chemical Reactions" Sim, students can explore the reaction between iron and sulfur to form iron sulfide. In this reaction, the iron atoms and sulfur atoms combine to form a new compound, iron sulfide, with different properties than the original iron and sulfur. The atoms of the iron and sulfur are rearranged to form new bonds, resulting in the formation of a new substance. This is an example of a chemical reaction, where the atoms of the two substances are rearranged to form a new compound with different properties.
Answer:
Explanation:A chemical response is a chemical transformation in which two chemicals combine to create a third component.
(i) Adding diluted acid to an active metal causes the test tube to heat up and hydrogen gas to escape, which results in the production of heat.
(ii) When diluted hydrochloric acid is added to silver nitrate, AgCl, a white precipitate, results.
(iii) When water is added to quicklime, the mixture boils and produces heat along with a hissing sound.
(iv) Thermal breakdown of mercury oxide - Mercury turns from red to a metallic silver tint as a result of this process.

Answer: The mass of silver is 1.19 X 10^14 M g
Explanation: The volume of the truck is 402 cubic feet or 1.138 x 10⁷ mm.
The density of silver is 10.49 g/mL.
We need to find the mass of silver that will fit in this moving truck. Density equals mass divided by volume. So,
d= m/v where m= mass m= d x VM=10.49 g/mL X 1.138 X 10∧7 mLM=119376200 g 1 gram=10⁻⁶ Megagram 119376200= 1.19 X 10^14 Mg hence the mass of silver is 1.19 X 10^14 M g hopefully this will help you please mark me as brainlist
