Answer:

A 12 oz Coca Cola contains 39g of sugar or C6H12O6. 

To calculate for the molarity of sugar in the soda, convert 39 grams of sugar to moles sugar:

39g/ 180.16 g/mol = 0.216 mol sugar

then, convert 12 oz to L:

12oz / (1oz/0.02957L) = 0.35484 L

therefore the concentration of sugar in the soda is:

M = mol sugar / L sol'n

   = 0.216 mol sugar / 0.35484 L

   = 0.609 M

The solubility of kL is 50g in 100 g h2o at 20 celcius. If 110 grams of of kL are added to 200 grams of h2o. What is happens ?
tia_tia [17]

Answer:

a saturated solution will form.

Explanation:

All solutions have a definite capacity of dissolving solute in it.

Unsaturated solutions are the solutions which contain less amount of solute than the maximum capacity of dissolving the solute. If more amount of solute is added in such a way a point is reached where addition of more solute cannot be dissolved. The solution is known as saturated solution.

Amount dissolved > Maximum solubility limit, the solution is saturated.

Amount dissolved < Maximum solubility limit, the solution is unsaturated.

If the amount of the salt exceeds the solubility limit, then the solution is saturated solution. If it is less than the limit given, then it is unsaturated solution.

Given,

50 g of KI is added to 100 g of water at 20 °C.

It means:

100 g of water can dissolve maximum of 50 g of  KCl.

Also,

1 g of water can dissolve maximum of 0.5 g of  KCl.

To check for 200 g of water:

200 g of water can dissolve maximum of (0.5)*200 g of  KCl.

Maximum amount of KCl that can be dissolved = 100 g

Actual amount dissolved = 110 g

Since,

Amount dissolved > Maximum solubility limit

110 g > 100 g

According to definition, the solution is saturated.

<u>Hence, a saturated solution will form.</u>

Which elements are main-group elements?<br> 1. Te<br> 2. K<br> 3. V<br> 4. Re<br> 5. Ag
Shkiper50 [21]

Answer:

Te

K

Explanation:

Main group elements are elements designated and located on the s-block and p-block on the periodic table. The core group or prominent elements are the elements that make up those groups. These groupings comprise the most naturally rich and abundant elements. The main group elements are those whose characteristics are more predicted as a function of their periodic table location. From the given options, only Te and K are elements of the main-group.

DNA has 2 strands. if the sequence of nucleotides of one strand was known, is it possible to use the information to determine th
ANTONII [103]
DNA has four main components.
Adenine=A
Cytosine=C
Guanine=G
Thymine=T

Since each letter has an opposite it would be possible by considering the pairs.
A:T
C:G

So, if one strand went as so:
AGCCTAGGTAC
The corresponding strand would be mirrored with the match: TCGGATCCTG

Calculate the number of photons having a wavelength of 12.0 μm required to produce 1.0 kJ of energy.
nika2105 [10]

Answer:

N = 603.32 × 10 ²⁰

Explanation:

Given data:

Wavelength of photon = 12.0 μm or 12 × 10 ⁻⁶ m

Energy = 1.0 KJ  or 1000 j

Number of photons = ?

Solution:

Formula:

E  = n . h . f

E = energy

N = number of photons

h = planck's constant

f = frequency

it is known that

f = c/λ

thus,

E = N . h . c / λ

Now we will put the values in formula.

1000 j = ( N. 6.63 × 10 ⁻³⁴ j.s × 3 × 10⁸ m/s ) / 12 × 10 ⁻⁶ m

N = 1000 j ×12 × 10 ⁻⁶ m  / 6.63 × 10 ⁻³⁴ j.s × 3 × 10⁸ m/s

N = 12000 j × 10 ⁻⁶ m / 19.89 × 10 ⁻²⁶ j. m

N = 603.32 × 10 ²⁰
