How do relationships among organisms help energy and matter flow through an ecosystem?

Chemistry
1 answer:
Scilla [17]3 years ago
7 0

Answer:

Producers, such as plants and green algae, use photosynthesis to turn the Sun's energy, water, and carbon dioxide in the air into complex organic compounds. Other producers, such as the bacteria living near deep-sea vents, can capture energy from other materials.

Explanation: try looking up on google :)

10.0 ml of 1.00 M HCl neutralized 20.0 ml of a NaOH solution. What was the molarity of the NaOH?
Viefleur [7K]

Answer:

0.500 M

Explanation:

The balanced equation for the neutralization reaction is as follows

NaOH + HCl —> NaCl + H2O

Molar ratio of NaOH to HCl is 1:1

Number of moles of NaOH reacted is equal to the number of HCl moles

We can use the following equation

c1v1 = c2v2

Where c1 is concentration and v1 is volume of HCl

c2 is concentration and v2 is volume of NaOH

Substituting the values

1.00 M x 10.0 mL = c2 x 20.0 mL

c2 = 0.500 M

Concentration of NaOH is 0.500 M

Write the formula for each compound (the composition is given after each name):
erastovalidia [21]
Aluminum bromide should be written as  AlBr₃ since we are told that there are 3 atoms of Br for every atom of Al.

I hope this helps.  Let me know if anything is unclear.

A compound contains 64.27% carbon, 7.19% hydrogen, and 28.54% oxygen. the molar mass is 168.19 g/mol. what is the molecular form
coldgirl [10]
Empirical formula is the simplest ratio of whole numbers of components in a compound 
calculating for 100 g of compound 
                                             C                             H                             O
mass                                  64.27 g                   7.19 g                     28.54 g
number of moles        64.27 g / 12 g/mol      7.19 g/1 g/mol     28.54 g / 16 g/mol 
                                        = 5.356 mol           = 7.19 mol           = 1.784 mol 
divide by least number of moles  
                                     5.356 / 1.784            7.19 / 1.784         1.784 / 1.784
                                      = 3.002                     4.03                     = 1.000
rounded off to nearest whole number 
 C - 3
 H - 4
 O - 1
empirical formula - C₃H₄O
 
 mass of empirical formula = 12 g/mol  x 3 + 1 g/mol x 4 + 16 g/mol x 1 = 56 g
molecular mass = 168.19 g/mol 
molecular formula is the actual ratio of elements making up the compound 
number of empirical units = molar mass of molecule / empirical mass
      empirical units = 168.19 g/mol  / 56 g = 3.00
there are 3 empirical units making up the molecular formula 
molecular formula = 3 x C₃H₄O

molecular formula = C₉H₁₂O₃

What would happen if the number of protons and electrons in the Atom did change
Vlad1618 [11]
When you change the number of protons in an atom, you will change the atom from one element to a different element. Sometimes, when you add a proton to an element, the element will become radioactive. If you change the number of electrons in an atom, you will get an ion of the element.
