Answer:

NiBr₃ + Al₂S₃ ⇒ NiS₃ + Al₂Br₃

Explanation:

A double replacement reaction is a reaction in which the cations switch anions.

In the reaction, the two cations are Al and Ni. The cations are Br and S.

Put each cation with the opposite anion: Ni with S and Al with Br.

The products would be NiS₃ and Al₂Br₃.

The full reaction is NiBr₃ + Al₂S₃ ⇒ NiS₃ + Al₂Br₃.

Hope that helps.

Can uae produce electricity from water

d1i1m1o1n [39]

Answer:

Flowing water creates energy that can be captured and turned into electricity. This is called hydroelectric power or hydropower. The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. ... This spins the turbines forward, activating the generators to produce electricity.

Thank you.....

Which characteristic best identifies a decomposition reaction?

gtnhenbr [62]

Answer:

Decomposition reaction = Those reactions in which single compound decompose down to give two or more products are called decomposition reaction .

Explanation:

Those reactions in which single compound decompose down to give two or more products are called decomposition reaction .

For the Decomposition reaction to take place , <u><em>a large amount of energy ias needed</em></u>. This is because for decomposition bonds are required to breaks. Hence energy is needed to break the bonds as they have strong force of attraction.

They occur in presence of HEAT , LIGHT , ELECTRICITY.

examples of decomposition reactions are:

$CaCO_{3}\rightarrow CaO+CO_{2}$

Here only one CaCO3 is producing two substances which are : CaO and CO2

This is also known as decompositon of Calcium carbonate and it require a lot of heat energy.

$2AgBr\rightarrow Ag + Br_{2}$

This is also a decomposition reaction , This occur in the presence of sunlight

Classify the following substances as a Bronsted-Lowry acid, Bronsted-Lowry base, Lewis acid, and/or Lewis base.A. HCl, BF_3,B. C

ZanzabumX [31]

Answer:

A. HCl -> Bronsted-Lowry acid, BF3 -> Lewis acid

B. CCl3 -> Lewis acid, -HC -> Lewis acid or Bronsted-Lowry acid

C. H2O -> Bronsted-Lowry acid or Bronsted-Lowry base, CH3Cl -> Lewis base

D.-OCH3 -> Lewis base, NH3 -> Bronsted-Lowry acid or Lewis base.

Explanation:

For the Bronsted-Lowry theory, acids are the substances that can donate a proton H+ and bases are the substances that can receive a pronto H+.

For the Lewis theory, acid is the substance that can gain a pair of electrons, and the base is the substances that can donate the pair of electrons.

A. HCl -> The substance has a proton (H+) and it can donate it, so it's a Bronsted-Lowry acid. BF3 -> The boron (B), still has space in its shells to receive a pair of electrons, so it's a Lewis acid.

B. CCl3 -> The carbon didn't make all the bonds it can do (4), so it still can receive electrons, thus it's a Lewis acid. -HC-> It can lose the proton (H+) as a Bronsted-Lowry acid, os gains a pair of electrons at the carbon, as a Lewis acid.

C. H2O -> It can gain a proton and forms the ion H3O+, or it can lose a proton and form the ion OH-, so it can be a Brosted-Lowy acid or a Bronsted-Lowry base. CH3Cl -> It can donate pair of electrons (the hydrogen is to attached to the carbon, so it will not be lost), so it works as a Lewis base.

D. -OCH3 -> The oxygen still has pairs of electrons, which it can donate, so it's a Lewis base. NH3 -> It can gain a proton and forms the ion NH4+, so it'll be a Bronsted-Lowry acid, but the nitrogen still has electrons, which it can donate, working as a Lewis base.
