How do composers interact with their ecosystem

1 answer:

4 0

<span>Composers or consumers eat the by-product of plants in order to get proper nourishment and development. Their waste excretions are in the soil which nourishes it. This is also used by the plants as producers in order to produce more food for the consumers. When consumers die, they become food for the decomposers such as worms, fungi, bugs, and ants so consumers help them to thrive. In the process, the soil becomes nourished of the mineral breakdowns from the body of the consumers, this is again used by producers to provide healthy and nourished foods.</span>

How many atoms are in 1.204x10^22 moles of arsenic?

ra1l [238]

Answer:

<h2>0.02 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

We have

$n = \frac{1.204 \times {10}^{22} }{6.02 \times {10}^{23} } \\ = 0.02$

We have the final answer as

<h3>0.02 moles</h3>

Hope this helps you

Balance the following chemical equation (which is for this reaction) and list the number of atoms of each element present before

Inga [223]

<h3><u>Answer and explanation</u>;</h3>

The balanced chemical equation will be;

NaHCO3 + CH3COOH = CH3COONa + H2O + CO2

After balancing the chemical equation the number of atoms of each element is the same on the reactants and on the products side.

Sodium atoms - 1

Hydrogen atoms - 5

Carbon atoms - 3

Oxygen atoms - 5

6. Write the ICE chart for the reaction of 32.0 g of sulfur and 71.0 g of chlorine: S8 + 4 Cl24S2Cl2 After completing the chart

Marianna [84]

Answer:

ICE Table Figure

a. 67.37 g $S_2Cl_2$

b. 35.62 g $Cl_2$

c. 58.61 g $S_2Cl_2$

Explanation:

For the <u>ICE table </u>we have to keep in mind that we have 4 moles of $Cl_2$ and 1 mol of $S_8$ and the reactives are consumed, so for $Cl_2$ we will have -4X and for $S_8$ we will have -X. Follow the same logic we will have -4X for $S_2Cl_2$ .

a. <u>Mass of the product</u>

Molar mass of $S_8$ = 256.52 g/mol

Molar mass of $Cl_2$ =70.9 g/mol

Molar mass of $S_2Cl_2$ =135.03 g/mol

We have to find the limiting reagent in the reaction:

$S_8+4Cl_2->4S_2Cl_2$

$\frac{32}{256.52}=0.124molS_8$

$\frac{71}{70.9}=1 molCl_2$

Divide by the coefficients in the balanced reaction:

$\frac{0.124}{1}=0.124mol$

$\frac{1}{4}=0.25 mol$

The limiting reagent would be $S_8$

Now is posible to calculate the amount of $S_2Cl_2$ produced:

$0.124molS_8\frac{4molS_2Cl_2}{1 molS_8}\frac{135.03gS_2Cl_2}{1 molS_2Cl_2}=67.37gS_2Cl_2$

b. <u>Mass in excess</u>

$0.124molS_8\frac{4molCl_2}{1 molS_8}\frac{70.9gCl_2}{1 molCl_2}=35.38gCl_2$

$Excess\hspace{0.1cm}=\hspace{0.1cm}71gCl_2-35.38gCl_2=35.62 gCl_2$

C. <u>87%Yield</u>

$67.37gS_2Cl_2\frac{87}{100}=58.61gS_2Cl_2$

Why methane has a low melting point

Leno4ka [110]

Simple molecular substances consist of molecules in which the atoms are joined by strong covalent bonds. However, the molecules are held together by weak forces so these substances have low melting and boiling points.
