Chemistry
1 answer:
Afina-wow [57]4 years ago
3 0

Answer is: b) decomposition.

Synthesis is reaction of two or more substances combining to make a more complex substance.

Decomposition is reaction where one substance is broken down into two or more simpler substances.

For example, balanced chemical reactio:

CaCO₃(s) → CaO(s) + CO₂(g).

Chemical decomposition is the separation of a single chemical compound (in this example calcium carbonate) into its two or more simpler compounds (in this example calcium oxide and carbon dioxide).

Combustion is reaction with oxygen.

Single Displacement is reaction where  neutral element metal or nonmetal become an ion as it replaces another ion in a compound.  

Double displacement reactions (more reactive metals displace metals with lower reactivity).

The delocalized cloud of π electrons in benzene is formed by the overlap of 6 ________ orbitals.
Radda [10]

The delocalized cloud of π electrons in benzene is formed by the overlap of 6<u> p-orbitals</u>.

So, option B is correct one.

In the case of hydrocarbons, delocalisation occurs in benzene rings , where a hexagon of six carbon atoms has decalized electrons spread over the whole ring.

All of the carbon atoms in the benzene rings are sp^{2} orbitals around the ring produces a framework of six sigma bonds, while the unhybridized p-orbitals which are perpendicular to this plane over in side-to-side fashion to form three pi-bonds.

Write the formula for the salts that are oxidizing agents in chlorine bleaches
Stella [2.4K]

Answer:- NaClO(sodium hypochlorite) and Ca(ClO)_2 (calcium hypochlorite) are the salts that are oxidizing agents in chlorine bleaches.

Explanations:- NaOCl reacts with water to form hypochlorous acid(HOCl) that works as a bleach as it could remove the color of the objects.

Hypochlorite ion can also produce chlorine ion and oxygen which also works as a bleach.

Explain, List the steps that show how the sunprovides the energy for surface ocean currents.
baherus [9]
The heat moves in predictable ways, flowing from warmer objects to cooler ones, until both reach the same temperature. When air is in contact with the ocean at a different temperature than the sea surface, heat transfer by a conductor. The ocean absorbs and stores energy from the sun and when precipitation falls , it release heat energy in the atmosphere(air)

marin [14]

Answer:

[A]²

Explanation:

Since the formation is independent of D, D is 0 order.

Since a quadruples when it is doubled it can be written as

2A^X= 4

To find the unknown power we can assume A= 1 to make the math simple. So When a = 2 (Because you doubled it) raised to X power it will equal 4

so the unknown power is 2

Making the rate law

[a]²[b]⁰

or simply just

[A]²
