Answer:
The pH scale has been drawn below.
Explanation:
pH sacle may be defined as the scale that determines the pH of acids and bases. 0 represent the neutral compounds. The compounds that pH less than 7 acts as acid whereas the compounds that have pH greater than 7 acts as base.
Here, water is neutral, Hydrochloric acid (HCl) is acidic and sodium hydroxide (NaOH) acts as base.
Water, hydrochloric acid, and sodium hydroxide can be placed on the pH scale as follows:
Water: Water is considered neutral and has a pH of 7. It falls in the middle of the pH scale.
Hydrochloric acid: Hydrochloric acid is a strong acid and is highly acidic. It has a pH below 7. The exact pH value of hydrochloric acid may vary depending on its concentration, but it typically falls within the range of 0 to 2.
Sodium hydroxide: Sodium hydroxide is a strong base and is highly alkaline. It has a pH above 7. Again, the specific pH value of sodium hydroxide can vary based on its concentration, but it typically falls within the range of 12 to 14.
So, on the pH scale, water would be placed at pH 7 (neutral), hydrochloric acid would be placed below pH 7 (acidic), and sodium hydroxide would be placed above pH 7 (alkaline).

A)chemical property
B)physical property
C)chemical change
D)physical change
The color is one among the B) physical properties.
The physical properties are visible or observable. The physical properties are measured with physical system. There are many physical properties which include color, size, radiance, luster, and so on. There are two types of physical quantities which includes intensive property and extensive property. This property depends on the change in the structure of the material.
The color of the substance depends on the color it is observing and illuminating which depends on the reflective property of the substance.
The color of ink is basically a physical property. The correct option is B.
Ink's colour is a tangiblecharacteristic. A substance's physical attributes are traits that may be seen or quantified without affecting its chemical makeup. Ink's appearance is referred to as its colour, which is determined by how it responds to light.
There are no chemicalreactions taking place, and the ink's chemical makeup does not change because it is an inherent quality of the ink itself.
Colour, smell, density, melting point, boiling temperature, and other qualities are examples of physicalproperties.
In the case of ink, the colour is a physical characteristic that aids in differentiating and identifying various types or ink formulations.
Thus, the correct option is B.

Answer:
Red blood cells are the most common formed element and they contain hemoglobin which is a respiratory pigment that can transport both oxygen and carbon dioxide throughout the body.
Explanation:
Red blood cells are the most common formed element in the blood and contain hemoglobin, a respiratory pigment that can transport both oxygen and carbon dioxide throughout the body.
Red blood cells are the most common formed element in the blood. They contain a respiratory pigment called hemoglobin, which is responsible for transporting oxygen andcarbon dioxidethroughout the body.
Hemoglobin binds to oxygen in the lungs, forming oxyhemoglobin, and carries it to the body's tissues. In the tissues, oxyhemoglobin releases oxygen, allowing it to be used by cells for various metabolic processes. At the same time, hemoglobin picks up carbon dioxide, a waste product of cellular respiration, and carries it back to the lungs for exhalation.
This process of oxygen and carbon dioxide transportis crucial for maintaining the body's overall oxygen levels and removing waste carbon dioxide. Without red blood cells and hemoglobin, the body would not be able to efficiently deliver oxygen to all cells and remove carbon dioxide.

The number of kcal he consumed by eating the 3 bars is 447 calories
We know that
1 gram of fat is 9 calories
1 gram of carbohydrate is 4 calories
1 gram of protein is 4 calories
So,
In one granola bar:
5 grams of fat = 5 x 9 = 45 calories
19 gram of carbohydrates = 19 x 4 = 76 calories
7 grams of protein = 7 x 4 = 28 calories
So,
total = 45 + 76 + 28 = 149 calories
Now
If Carter ate 3 granola bars so 149 x 3 = 447 calories

Answer:
447 calories
Explanation:
1 gram of fat is 9 calories
1 gram of carbohydrate is 4 calories
1 gram of protein is 4 calories
In one granola bar:
5 grams of fat = 5 x 9 = 45 calories
19 gram of carbohydrates = 19 x 4 = 76 calories
7 grams of protein = 7 x 4 = 28 calories
for a total of 45 + 76 + 28 = 149 calories
If Carter ate 3 granola bars then 149 x 3 = 447 calories
