The energy in the bonds in glucose will be broken down and transferred to ATP molecules.

Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules in their cells.

The equation for cellular respiration is as follows:

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

Based on the illustration using the above equation, the energy stored in the bonds of glucose molecule is broken down and used to synthesize ATP molecules.

A side reaction occurs when acid is added to the system, so the species reacts with the acid is base.

Acids are those species which have a pH range in between 0 to 7, generally acids are present with hydrogen atom in their molecular formula.

If in any reaction after adding the acid, side reaction wiull occur then in this condition base will reacts with the acid as it has the opposite behavior as of acid and formation of salt & water molecules takes plavce.

Hence the needed species is base.

Answer:

Explanation:

starch, a white, granular, organic chemical that is produced by all green plants. Starch is a soft, white, tasteless powder that is insoluble in cold water, alcohol, or other solvents.

Starch is amongst the most abundant plant products and is a mixture of two polymers, amylose and amylopectin. During food processing starch is transformed by hydrothermal treatments. ... The structure of starch is also influenced by specific and non-specific interactions with other food constituents and ingredients.

Answer: Ammonia, an alkaline chemical, is used to raise the pH level (it's levels of acidity) of our hair during the colouring process. This then lifts the cuticles of the hair fibre and allows the colour to be deposited onto the cortex (the inner part of the hair protected by the cuticles). In hair coloring products, ammonium hydroxide is used to support the lightening action of hydrogen peroxide and to prepare hair to accept color pigments. Alkaline properties of ammonia raise the cuticle and allow peroxide and dye molecules to penetrate the hair shaft. (creds to the internet)

Answer:

Polythene has the lowest melting/boiling point from all the other covalent structures mentioned in this question.

Answer:

Polythene (polyethene according the IUPAC nomenclature.)

Explanation:

Consider the structure of each option:

Melting each structure requires overcoming the forces that hold the structure rigid:

Van der Waal forces are much easier to break than covalent bonds.

Hence, the melting point of polythene would be the lowest among the options.

The molecular formula of the compound is C6H12O6.

1) We know that;

1 mole of CO2 contains 6.02 X 10^23 atoms

x moles of CO2 contains 1.5 X 10^23 atoms

x = 1 mole X  1.5 X 10^23 atoms /6.02 X 10^23 atoms

x = 0.25  moles of CO2

2) 1 mole of pure Al has 27 g

x moles of Al has 5 g

x = 1 mole ×  5 g/ 27 g

x = 0.19 moles

If 1 mole of Al contains 6.02 X 10^23 atoms

0.19 moles of Al contains 0.19 moles  ×  6.02 X 10^23 atoms /1 mole

= 1.14 X 10^23 atoms

3) From 2Na + Cl2 ---> 2NaCl;

2 moles of Na produces 2 moles of NaCl hence 3 moles of Na will also produce 3 moles of NaCl.

4) The molar mass of K2SO4 is obtained from;

2(39) + 32 + 4(16) = 78 + 32 + 64 = 174 g/mol

Now;

Percentage by mass of K = 2(39)/ 174  ×  100/1 = 44.8%

Percentage by mass of S = 32/174 ×  100/1 = 18.4%

Percentage by mass of O = 4(16)/174 ×  100/1 = 36.8%

5) The reaction equation is;

4Al(s) + 3O2(g) ----> 2Al2O3

Total mass present =  162g + 144g = 306 g

Mass percent of Al =  162g/ 306 g ×  100/1 =52.9%

6)

C - 40/12     H -  6.71/1        O - 53.29/16

C - 3.33      H - 6.71            O - 3.33

Dividing through by the lowest ratio

C- 3.33/3.33     H - 6.71/3.33    O - 3.33/3.33

C - 1                  H - 2                 O - 1

The empirical formula is CH2O

Now;

[12 + 2(1) + 16] n = 180.16

30n = 180.16

n = 180.16/30

n = 6

The molecular formula is C6H12O6.

Answer:

170 dm³ (2 significant figures)

Explanation:

CH₄ + 2O₂ → CO₂ + 2H₂O

We need to find how much 'volume' of O₂ is required to burn 56 g of CH₄.

Let's take the ratios of the two gases only.

CH₄ : 2O₂ (in terms of moles the ratio is 1:2)

56g : x dm³

Mr of CH₄ : Volume of oxygen at rtp

Find the Mr of CH₄.

Mr of CH₄ = 12 + (1 × 4) = 16

We know that 1 mole of any gas occupies 24 dm³ at room temperature and pressure (rtp). We have to find the volume of oxygen, there are 2 moles of oxygen, so 2 moles of gas will occupy:

2 × 24 = 48 dm³

56g : x dm³

  16 : 48 dm³

16x = 56 × 48

16x = 2688

x = [tex]\frac{2688}{16}[/tex]

x = 168 dm³

∴ the minimum volume of oxygen gas, at room temperature and pressure required to completely burn 56g of methane gas is 170 dm³
