Answer:

This reaction is a single replacement reaction.

Explanation:

Step 1: Data given

A single-replacement reaction is a reaction in which one element replaces a similar element in a compound. The general form of a single-replacement (also called single-displacement) reaction is:

A+BC→AC+B

A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances. The general form of a decomposition reaction is:

AB→A+B

A double-replacement reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds. The general form of a double-replacement (also called double-displacement) reaction is:

AB+CD→AD+BC

A combustion is a high-temperature exothermic (heat releasing) redox (oxygen adding) reaction between a fuel and an oxidant, usually atmospheric oxygen.

Whenever we complete a combustion reaction of a hydrocarbon (compound of C and H) we generally  have the same products formed: CO2 and H2O.

Na (s) + H2O (l) → NaOH (aq) + H2 (g)

This reaction is not a decomposition because we don't break down a compound.

This reaction is not a combustion because we don't oxidze a compound to form CO2 and H2O

This reaction is a replacement reaction. But only a single replacement reaction because one element replaces a similar element in a compound

Answer:

The answer to your question is Single replacement

Explanation:

Data

Chemical reaction

                 Na  +  H₂O  ⇒   NaOH  +  H₂

Single replacement  is a chemical reaction in which a metal replaces the cation of a compound.

Decomposition  is a chemical reaction in which a compound forms 2 or more products.

Double replacement  in this chemical reaction two compounds react interchanging their cations and anions.

Combustion in this chemical reaction the reactants must be a compound with carbon and the other oxygen and the products must be carbon dioxide and water.

Explain why an atom can only emit specific wavelengths of light and not every possible wavelength
ella [17]

Answer:

<em>The electrons in an atom can only occupy certain allowed energy levels to a lower one</em>, the excess energy is emitted as a photon of light, with its wavelength dependent on the change in electron energy. This is why an atom can only emit specific wavelengths of light and not every possible wavelength.

When the submarine's density is equal to the density of the surrounding seawater, the submarine will maintain depth. If a 103200
GaryK [48]

Answer:

2.023 m^3 is the total displacement (volume) of the submarine.

Explanation:

Mass of water carried by submarine at 1000 ft depth = m = 2100 kg

The density of seawater at 1000 ft depth = d = 1033 kg/m^3

Volume of the water displaced = V= ?

Total displacement of the submarine = Volume of the water displaced = V

Density=\frac{Mass}{Volume}

V=\frac{m}{d}=\frac{2100 kg}{1033 kg/m^3}=2.023 m^3

2.023 m^3 is the total displacement (volume) of the submarine.

Consider a mixture of soil and water and compare it to a colloid, such as milk. Which property best differentiates these two mix
mezya [45]
There are many differentiates between them. Like if you standing these two mixture, the soil and water will separate while milk will not. And colloid have tyndall effect while soil and water doesn't have.

6.0 moles of Na and 4.0 moles of Cl2 are mixed, how manu moles of NaCl in moles cane be made from this mixture
Sladkaya [172]

Answer:

Moles of NaCl formed is 6.0 moles

Explanation:

We are given the equation;

2 Na(s) + Cl₂(g) → 2 NaCl(s)

  • Moles of Na is 6.0 moles
  • Moles of Cl₂ is 4.0 moles

From the reaction;

2 moles of sodium reacts with 1 mole of chlorine gas to form 2 moles of NaCl

In this case;

6 moles of Na would require 3 moles of Cl₂, this means that chlorine gas is in excess.

Thus, the rate limiting reagent is sodium.

But, 2 moles of sodium reacts to form 2 moles of NaCl

Therefore;

Moles of NaCl = Moles of Na

                      = 6.0 moles

Thus, moles of sodium chloride produced is 6.0 moles
