The correct answer is option D) Both A and C are correct.

Carbohydrates are the hydrate of carbon and they are large macromolecules made of carbon (C), hydrogen (H), and oxygen (O). They can be found as starch, cellulose, and sugars in food and living tissues.

Carrots also produce natural sugar, which provides energy for the plant to reproduce. This sugar is then delivered to the storage organs of carrots (the root). Then the sugar is transformed into starch because starch is non-soluble and hence it is easier to store it.

However, when plants need energy, this starch is converted back into sugar by the activity of an enzyme. Depending on how much sugar is still available, carrots and similar plants vary in sweetness.

A nonmetal is a chemical element that doesn't have a lot of metallic characteristics; examples include colourless gases (like hydrogen) and glossy, solids with high melting points (like boron).

Dull, brittle and non conductive best describes which of the following:

"S - Sulfur"

A Non-metallic Chemical element sulfur has the letter S and atomic number 16. It is multivalent, nonmetallic, and plentiful. Sulfur atoms normally combine to create cyclic octatomic molecules, which have the chemical formula S8. At room temperature, elemental sulfur is a crystalline solid that is brilliant yellow.

When compared to metals, nonmetals' electrons exhibit different behaviour. With a few exceptions, nonmetals don't have any moving parts, which makes them often poor heat- and electricity-conductors and brittle or crumbly when solid. Metals are good conductors since their electrons are typically free to move about, and the majority of them are also simple to flatten into sheets and draw into wires. Nonmetal atoms have varying degrees of electro negativeness, which makes them more likely to draw electrons in chemical processes and produce acidic compounds.

A reactive metal can displace HYDROGEN gas either from water or from an aqueous acid.

A MORE reactive metal can also displace the ion of a LESS reactive metal from the solution.

A less reactive metal can be displaced by a more reactive metal (one that produces positive ions more readily). An example of this is a displacement reaction.

The more reactive metal thus enters the solution as a cation, while the cations of the less reactive metal are changed into metal. In their salt solutions, more reactive metals thus displace less reactive metals.

Only when a metal is situated above another metal in the reactivity series may one metal remove another metal from a complex.

The percent abundance for Fe-57 in the attached photo if the average atomic mass for Fe is 55.845 u is 2.1%.

The relative abundance is the percentage of a particular isotope that occurs in nature.

According to this question, four isotopes of Fe (iron) was given. The percent abundance can be calculated using the following expression;

M1(0.05845) + M2(0.91754) + M3 (x) + M4 (y) = M(E)

Where;

3.153 + 51.32 + 56.9354x + 57.9333y = 55.845

56.9354x + 57.9333y = 55.845 - 54.475

56.9354x + 57.9333y = 1.37......eqn 1

0.97599 + x + y = 1

x + y = 0.02401.......eqn 2

Solving both equations simultaneously using substitution method

x = 0.02401 - y

56.9354 (0.02401 - y) + 57.9333y = 1.37

1.3670 - 56.9354y + 57.9333y = 1.37

1.3670 + 0.9979y = 1.37

0.9979y = 0.003

y = 0.003006

x = 0.02401 - y

x = 0.02401 - 0.003006 = 0.021

Therefore, the percent abundance for Fe-57 in the attached photo if the average atomic mass for Fe is 55.845 u is 2.1%.

0.5634 g of KHP was dissolved in 50.00 mL of the standardization titrant.

1 mol of potassium hydrogen phthalate reacts with 1 mol of sodium hydroxide to form 1 mol of potassium sodium phthalate and 1 mol of water. Because of this molar ratio, the amount of NaOH used will be equal to the amount of KHP present in the sample of the standardization titrant.

c = n/V, so n = c * V = 0.049 M * 0.025 L = 0.001225 mol of NaOH and KHP

With this information, we can obtain the moles of KHP present in the 50.00 mL of the titrant:

22.20 mL : 0.001225 mol = 50.00 mL : X

X = 0.001225 mol * 50.00 mL / 22.20 mL = 0.002759 mol

The next step is utilizing the potassium hydrogen phthalate molar mass (204.22 g/mol), to calculate the grams of it dissolved in the sample:

n = m/M, so m = n * M = 0.002759 mol * 204.22 g/mol = 0.5634 g

w/v percentage of a dextrose solution with an osmolarity of 100 mosmol/L would be 1.9817%.

Because dextrose does not disassociate in an aqueous solution, the osmolarity of the solution is equal to its molarity, so we have a 100 mmol/L (or 100 mM or 0.1 M) dextrose solution. That means that, in 100 mL (0.1 L) of this solution, we have:

c = n/V, so n = c x V = 0.1 M x 0.1 L = 0.01 mol

n = m/M, so m = n x M = 0.01 mol x 198.17 g/mol = 1.9817 g of dextrose

w/v percentage would be:

The temperature in degrees Fahrenheit is -49°F and the temperature in Kelvin is 228K.

How does temperature conversion take place?

Celsius to Fahrenheit-

In order to convert temperature in degrees Celsius to Fahrenheit, the formula we use is  multiplied by 1.8 (or 9/5) and added to 32.

i.e,  (°C × 9/5) + 32 = °F

Given the water freezes at -45°C, so temperature in degree Fahrenheit is

                    (-45°C × 9/5) + 32 = -49°F

Celsius to Kelvin-

In order to convert the degrees Celsius to Kelvin, the formula we use  is

Kelvin = Celsius + 273.15.

i.e, K = °C + 273.15

Given the water freezes at -45°C, so temperature in Kelvin is

                         K = -45 + 273.15 = 228 K

So after conversion the temperature in degrees Fahrenheit is -49°F and the temperature in Kelvin is 228 K.

Answer:

i think it might be diseased people. but im not sure

Explanation:

A17.90-gram sample of iron is heated in the presence of excess iodine a metal iodide is formed and the empirical formula of the compound is Fe1I2.

The empirical formula, which is defined as the ratio of subscripts of the least whole number of the elements present in the formula, is the simplest formula for a compound.

Mass of Fe= 17.90 g

Mass of metal iodide = 99.24 g

Now we have to calculate the mass of iodide.

Mass of I = Mass of metal iodide - Mass of Fe

Mass of I = 99.24 - 17.90

Mass of I = 81.34 g

To formulate the empirical formula, we need to follow some steps:

First, we convert the given masses into moles.

Moles of Fe = Given mass/ molar mass = 17.90/55.93 = 0.32 moles

Moles of I = given mass/ molar mass = 81.34/126 = 0.64 moles

To calculate the mole ratio, we divide each value by the smallest number of moles that is 0.32 moles.

For Fe = 0.32/0.32 = 1

For I = 0.64/0.32 = 2

Hence the mole ratio is

Fe:I = 1:2

Thus, the empirical formula would be Fe1I2

Making a solution of sodium chloride for an experiment , we add 250 mg of sodium chloride to 500 ml of lab water. the sodium chloride concentration of solution in unit of mg/l is 499.7 mg/l and in ppm is 499.7 mg/l.

mass of solute = 250 mg = 0.250 g

volume of solvent = 500 ml = 500 g

mass of solution  = 0.250 g + 500 g = 500.25 g

concentration of solution in ppm ( parts per million ).m

= ( mass of solute in g / mass of solution in g  ) × 1000000

= ( 0.250 g / 500.25 g) × 1000000
