What are some examples of high-sodium processed foods?
What role does the sodium-potassium ratio (Na/K) play in good health?
What foods are naturally high in potassium (K)?
Sodium chloride is just one of many possible salts. What are salts? How does asalt form? (Hint: An acid and a base are involved, and a salt is neutral in pH.)
Potassium chloride has the chemical formula KCl. It is a salt that is used as a substitute for NaCl in order to reduce sodium intake. Both salts are composed of metal and halogen ions. Would you expect potassium to have properties similar to those of sodium? Why or why not?
Compare and contrast NaCl and KCl as food additives. For example, how do they taste and how good are they for cooking?
Answer:
HERE IS UOUR ANSWER MATE.............
➡️High-Sodium Foods are :-
1) Smoked, cured, salted or canned meat, fish or poultry including bacon, cold cuts, ham, frankfurters, sausage, sardines, caviar and anchovies.
2) Frozen breaded meats and dinners, such as burritos and pizza.
3) Canned entrees, such as ravioli, spam and chili.
4) Salted nuts.
5) Beans canned with salt added.
➡️ Reducing sodium and increasing potassium in your diet can help control hypertension and lower your risk of cardiovascular disease and death. Lowering blood pressure reduces the risk of heart disease and stroke.
➡️Many fresh fruits and vegetables are rich in potassium:
1 . Bananas
2 . oranges
3 . Cantaloupe
4 . Honeydew
5 . Apricots
6 . Grapefruit
(some dried fruits, such as prunes, raisins, and dates, are also high in potassium)
7 . Cooked spinach.
8 . Cooked broccoli.
9 . Potatoes.
10 . Sweet potatoes.
11 . Mushrooms.
12 . Peas.
13 . Cucumbers.
➡️ A salt is a chemical compound consisting of an ionic assembly of cations and anions. Salts are composed of related numbers of cations and anions so that the product is electrically neutral.
Salt ( for chemistry) is a substance produced by the reaction of an acid with a base. A salt consists of the positive ion (cation) of a base and the negative ion (anion) of an acid.
➡️Most of the salt in food, as well as the salt in a shaker, is sodium chloride. Sodium chloride isan ionic compound with the chemical formula NaCl. Processed foods contain a lot of salt and therefore a lot of sodium (Na). As a result, many people consume too much of this alkali Earth metal.
High-sodium diets have been linked to high blood pressure. High blood pressure, in turn, increases the risk of stroke, heart attack, and kidney failure. Reducing sodium intake may help prevent these health problems.

If we took 8 moles of carbon how many grams(mass) it would be??
Answer:
Mass = 96 g
Explanation:
Given data:
Number of moles of C = 8 mol
Mass of C in gram = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of C = 12 g/mol
8 mol = mass / 12 g/mol
Mass = 8 mol × 12 g/mol
Mass = 96 g
18. What is the maximum temperature for holding cold, potentially hazardous food?
A. 32 degrees farenheit
B. 40 degrees farenheit
C. 41 degrees farenheit
D. 70 degrees farenheit
Answer: I believe the correct answer is C. 41 degrees Fahrenheit.
Explanation: Time and temperature are the most essential elements for monitoring the growth of disease-causing bacteria in food. The temperature danger zone lies between 40 degrees Farenheit and 140 degress Fahrenheit.

Does solubility have any unit? Answer properly
Answer:
Water solubility is a measure of the amount of chemical substance that can dissolve in water at a specific temperature. The unit of solubility is generally in mg/L (milligrams per liter) or ppm (parts per million). You can often find it in the section 9 of a safety data sheet (SDS).

How mariy molecules of water are in a 500.3 g sample?
Answer:
1.67×10^25 molecules
Explanation:
No of molecules = no of moles × Avogadros number
No of moles= mass in gram / molar mass
No of moles of water in given sample = 500.3/18
= 27.79 moles
No of molecules = 27.79× 6.02×10^ 23
= 167.32×10^23 or 1.67×10^25

What is the total amount of heat needed to change 2250 g of silver at 200.0°C to 0.0°C? The specific heat of silver is 0.129 J/g∙°C
Answer:
The total amount of heat needed to change 2250 grams of silver at 200 ºC to 0ºC is 5805 J.
Explanation:
The melting point of silver is 961.8 ºC, meaning that heat released is entirely sensible. Therefore, the amount of heat released by the sample of silver ([tex]Q[/tex]), measured in joules, is determined by the following formula:
[tex]Q = m\cdot c\cdot (T_{f}-T_{o})[/tex] (1)
Where:
[tex]m[/tex] - Mass, measured in kilograms.
[tex]c[/tex] - Specific heat of silver, measured in joules per grams-degrees Celsius.
[tex]T_{o}[/tex], [tex]T_{f}[/tex] - Initial and final temperatures, measured in degrees Celsius.
If we know that [tex]m = 0.225\,kg[/tex], [tex]c = 129\,\frac{J}{kg\cdot^{\circ}C}[/tex], [tex]T_{o} = 200\,^{\circ}C[/tex] and [tex]T_{f} = 0\,^{\circ}C[/tex], then the heat received by the sample of silver is:
[tex]Q = (0.225\,kg)\cdot \left(129\,\frac{J}{kg\cdot ^{\circ}C} \right)\cdot (0\,^{\circ}C - 200\,^{\circ}C)[/tex]
[tex]Q = -5805\,J[/tex]
The total amount of heat needed to change 2250 grams of silver at 200 ºC to 0ºC is 5805 J.

In one or two sentences, make and justify a claim about the frequency of a wave if the wavelength increases and the velocity stays the same.
Answer:
The relationship between the frequency of a wave and the wavelength is an inverse relationship, therefore, if the wavelength of a wave increases and the velocity of the wave stays the same, the frequency of the wave decreases.
An example is the ocean wave, if the distance between successive wave crests, which is the wavelength, 'λ', of the wave, increases, while the velocity, 'v', of the wave coming to shore remains the same, the number of wave crest arriving at the beach in a given period of time, which is the frequency of the wave, 'f', decreases according to the following equation;
f = v/λ
Explanation:
The frequency and wavelength have inverse relationship. With increase in wavelength there has been a decrease in frequency when speed has been kept constant.
Wavelength has been defined as the distance traveled by the wave in a unit time, while frequency has been defined as the rate of the repetition of the wave in unit time.
The relationship between the wavelength and frequency has been given by;
Wavelength = [tex]\rm \dfrac{speed}{frequency}[/tex]
Since the speed has been constant, there has been an inverse relationship between the frequency and wavelength. Thereby with increase in wavelength there has been a decrease in frequency and vice versa.
