Answer:

C6H12O6 → 2C2H5OH + 2CO2

Explanation:

Glucose is an organic molecule, specifically a sugar, with the formula C612O6 while ethanol is another organic molecule with formula; C2H5OH.

However, as rightly said in this question, ethanol can be got from glucose via a process called fermentation in the presence of a catalyst called YEAST. The balanced equation is as follows:

C6H12O6 → 2C2H5OH + 2CO2

Answer:

Photosynthesis.

Explanation:

In photosynthesis process, carbondioxide gas enters into plant leaves from which plant produces organic molecules such as glucose. This glucose helps the plant to increase it growth and complete development stages and finally the plant dies and buried in the soil so due to decomposition process, the carbon present in the plant body releases in the soil and become part of sediments. So indirectly photosynthesis process provides carbon to the soil.

25.4g of potassium phosphate (K3PO4) are formed.

Potassium phosphate is an inorganic salts of potassium and phosphate.

3 KOH + H3PO4 → K3PO4 + 3 H2O

Step 1: Convert from grams to moles using the molar mass.

Step 2: Use the molar ratio to determine moles of other substance.

Step 3: Convert from mole to grams using the molar mass.

Convert grams to moles using the molar mass

25.4g KOH (1 mol KOH/56.098g KOH)

= 0.3593mol KOH

Mass of H3PO4 produced

0.3593 mol KOH ( 1 mol H3PO4/3 mol KOH)

= 0.1197 mol H3PO4

converting mole to grams

0.1197 mol H3PO4 (98g H3PO4/1 mol H3PO4)

= 11.730g H3PO4

Mass of K3PO4 produced

0.3593 mol KOH (1 mol K3PO4/3 mol KOH)

= 0.1197 mol K3PO4

converting mole to grams

0.1197 mol K3PO4 (212.267g K3PO4/1 MOL K3PO4)

= 25.408g K3PO4

Hence, option b is the correct answer.

Explanation:

Given data:

Mass of mercury = ?

Volume of mercury = 3426 mL

Density of mercury = 13.6 g/mL

Solution:

Formula:

d = m/v

d = density

m = mass

v = volume

by putting values,

13.6 g/mL = m/ 3426 mL

m =  13.6 g/mL × 3426 mL

m = 46593.6 g

Answer:

A cation is an ion with fewer electrons than protons. Therefore, it has a positive charge. The electric charge on a proton is equal in amount to the charge on an electron. Anions are atoms or radicals (groups of atoms), that have gained electrons. Since they now have more electrons than protons, anions have a negative charge. Halogens always form anions, alkali metals and alkaline earth metals always form cations. Most other metals form cations (e.g. iron, silver, nickel), whilst most other nonmetals typically form anions (e.g. oxygen, carbon, sulfur).

Explanation:

An anion and cation cannot be specifically found on the periodic table.    

The chemical elements are shown in tabular form on the periodic table, sometimes referred to as the periodic table of the elements. It is frequently used in physics, chemistry, and other sciences and is frequently regarded as a symbol of chemistry.

An ion with fewer electrons than protons is known as a cation. It is hence positively charged. Protons and electrons both have the same amount of electric charge. Atoms or radicals (groups of atoms) that have gained electrons are known as anions. Anions now have a negative charge because they have more electrons than protons.

Alkali metals and alkaline earth metals always produce cations, while halogens always produce anions. Iron, silver, and nickel are among the most common non-metals that create cations, whereas the majority of other metals do the same (e.g. oxygen, carbon, sulphur).

The periodic table does not clearly list an anion or cation.

Answer:

High explosives do not need to be contained to make their bang. Nitroglycerine, trinitrotoluene, and RDX are high explosives.

Explanation:

Answer:

116 years

Explanation:

To solve this, we will use the half life equation;

A(t) = A_o(½)^(t/t_½)

Where;

A(t) is the amount of strontium left after t years;

A_o is the initial quantity of strontium that will undergo decay;

t_½ is the half-life of strontium

t is the time it will take to decay

We are given;

A(t) = 7.5 g

A_o = 120 g

From online values, half life of strontium-90 is 29 years. Thus, t_½ = 29

Thus;

7.5 = 120 × ½^(t/29)

Divide both sides by 120 to get;

7.5/120 = ½^(t/29)

0.0625 = ½^(t/29)

In 0.0625 = (t/29) In ½

-2.772589 = (t/29) × (-0.693147)

(t/29) = -2.772589/(-0.693147)

t/29 = 4

t = 29 × 4

t = 116 years
