 is most likely to undergo beta decay.

During the process of beta decay the mass number of the parent nuclide becomes equal to the newly created nuclide. On the other hand, the atomic number of the newly created nuclei increases or decreases by one unit.

Answer:

5 will come in blank

4KMnO₄ ----------> 2K₂O + 4MnO + 5O₂

Explanation:

Reaction:

4KMnO₄ ----------> 2K₂O + 4MnO + ____O₂

this reaction is the dissociation reaction in which KMnO₄ is break down into its component.

KMnO₄ upon dissociation gives Potassium oxide, manganese oxide and liberate oxygen

Balance Chemical Equation:

A balanced chemical equation is that in which the the number of the reactant atoms equal to the number of the product atom.

For example if the oxygen at the reactant side is 4, the number of oxygen should be 4 on the product side.

So for this purpose we have to balnce the reaction and number of atoms on each side of the arrow

if we see the given Equation

Numbers of atom on reactant Side:

K = 4

Mn = 4

O = 16

Numbers of atom on reactant Side:

K = 4

Mn = 4

O = 6 instead of blank oxygen molecule

so from the above data we have 10 oxygen less.

If we put the 5 in the blank then we will have 10 oxygen and equation will be balanced

So the balanced Equation will be

4KMnO₄ ----------> 2K₂O + 4MnO + 5O₂

A submarine fills a special storage area known as ballast with water in order to increase its density. This allows it to dive de

Art [367]

Answer:

The submarine will rise.

Explanation:

To get a submarine to surface, the main vents in the top of the tank are closed and high-pressure compressed air is blown into the ballast tanks, forcing the water out through the flood ports at the bottom of the tank. This increases the vessel's displacement.

Happy Hollidays!! :)

A formulation scientist is creating a formula for a new product that requires the following compounds: barium chloride, silicon

grandymaker [24]

Answer:

Yes. These chemicals named barium chloride and calcium carbonate have been named properly. But silicon oxide has not been named correctly, an oxide of silicon is named as silicon dioxide not silicon oxide.

Explanation:

In chemistry while naming chemicals there are certain rules and naming the chemicals as per these rules is known as chemical nomenclature. The IUPAC's rule for chemical nomenclature of inorganic compounds can be read in a book named as red book.

By sign convention, a cation is named first followed by an anion. For example, in barium chloride (BaCl₂), barium which is represented by symbol Ba²⁺ is a cation and therefore written before chloride (Cl⁻) which is an anion. Similarly calcium carbonate is represented as CaCO₃.

As per the valency of silicon, it forms a dioxide with oxygen atom and it is represented as SiO₂.

one million atoms of a particular element have a mass of 1.99 ×10^-17 grams. how many moles of this element are there?

Marianna [84]

(1.99x10^-17) x 1000000
= 1.99x10^-11 (1.99x10^-11) / (6.023x10^23)
= 3.304001328x10^-35
hope this helps

Before we can use this equation for

AlexFokin [52]

Answer:

2C₂H₆ + [7]O₂ → [4]CO₂ + [6]H₂O

Explanation:

Chemical equation:

C₂H₆ + O₂ → CO₂ + H₂O

Balanced chemical equation:

2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O

Step 1:

2C₂H₆ + O₂ → CO₂ + H₂O

Left hand side Right hand side

C = 4 C = 1

H = 12 H = 2

O = 2 O = 3

Step 2:

2C₂H₆ + O₂ → 4CO₂ + H₂O

Left hand side Right hand side

C = 4 C = 4

H = 12 H = 2

O = 2 O = 9

Step 3:

2C₂H₆ + O₂ → 4CO₂ + 6H₂O

Left hand side Right hand side

C = 4 C = 4

H = 12 H = 12

O = 2 O = 14

Step 4:

2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O

Left hand side Right hand side

C = 4 C = 4

H = 12 H = 12

O = 14 O = 14
