A. LITTORAL ZONE is a freshwater ecosystem that is home to rooted plants.

Littoral zone is the shallow area of a lake, pond, river or ocean. This is the area where mangroves grow.

Some counties and water district identify littoral zones so that these zone will be planted with native plants. This is done for the purpose of having the plants purify the water and maintain a balanced ecosystems.

How many moles of carbon atoms is 7.72 x 10 ^24 atoms of carbon? Round to 2 decimal places
soldier1979 [14.2K]

Answer:

<h2>12.82 moles </h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{7.72  \times {10}^{24} }{6.02 \times  {10}^{23} }  \\  = 12.8 239

We have the final answer as

<h3>12.82 moles</h3>

Hope this helps you

What is the angle between the carbon-sulfur bonds in the carbon disulfide ( cs2 ) molecule?
Bingel [31]

Answer:

180º

Explanation:

Carbon has 4 valence electrons and to complete the octet requires 4 more , so it will share with the oxigen atoms 4 more, forming a single and a pi bond similar to CO2

Since the carbon does not have lone pairs, the geometry around this central atom will be linear and the angle will be 180 ,   S = C = S

The density of the hydrocarbon in part (a) is 2.0 g l-1 at 50°c and 0.948atm. (i) calculate the molar mass of the hydrocarbon. (
Vedmedyk [2.9K]

1. Answer;

=56 g/mol

Explanation and solution;

PV = nRT

nRT= mass/molar mass (RT)

molar mass = (mass/V ) × (RT/P)

                   = Density × (RT/P)

Molar mass = 2.0 g/L × (0.0821 × 323 K)/0.948 atm

Molar mass = 56 g/mol


2. Answer;

Molecular mass is C4H8

Explanation;

Empirical mass × n = molar mass

Empirical mass for CH2 = 14 g/mol

Therefore;

56 g/mol = 14 g/mol × n

   n = 4

The molecular formula= 4(CH2)

    = C4H8
