A metamorphic rock can turn into an igneous rock if it becomes hot enough to melt. Then, when it cools enough to become solid the result will be an igneous rock. An igneous rock can become metamorphic, if it is under pressure when it is heated. The pressure will keep the rock from melting but will allow the atoms to unite with our atoms forming new minerals when the rock cools. The resulting metamorphic rock will have some new minerals that the igneous didn't have. The new minerals will have a ordered physical arrangement unlike the random mixture of an igneous rock.

Identify the bronsted-lowry acid and the bronsted-lowry base in this reaction on the left side of each of the following equation

Dahasolnce [82]

<u>Answer:</u> $NH_4^+$ is an acid, $CN^-$ is a base, $NH_3$ is conjugate base and $HCN$ is conjugate acid

<u>Explanation:</u>

According to Bronsted and Lowry's theory:

An acid is defined as a proton donor while a base is defined as a proton acceptor.

In a chemical reaction, an acid loses a proton to form a conjugate base while a base accepts a proton to form conjugate acid.

For the given chemical reaction:

$NH_4^+(aq)+CN^-(aq)\rightleftharpoons HCN(aq)+NH_3(aq)$

$NH_4^+$ is losing a proton thus it is an acid to form $NH_3$ which is its conjugate base

$CN^-$ is gaining a proton thus it is a base to form $HCN$ which is its conjugate acid

Hence, $NH_4^+$ is an acid, $CN^-$ is a base, $NH_3$ is conjugate base and $HCN$ is conjugate acid

erik [133]

Answer:

please rate my answer 5 Star

Explanation:

Using Boyle's Law,

The pressure exerted by a gas is inversely proportional to the volume the gas is occupying provided the temperature is constant

p*v = constant

100*1000*7.5 = p * 11

p = 750000/11

yarga [219]

Answer:

The structure of the major organic product isolated from the reaction of 1-hexyne with hydrogen chloride (2 mol) is attached below.

Explanation:

Hydracids are added to triple bonds by a mechanism similar to that of the addition to double bonds. The regioselectivity of the addition of H-X to the triple bond follows the rule of Markovnikov, where the Z conformation predominates in the addition of halide to the alkyne, because in the formation of the carbocation it prefers to place the positive charge on the more substituted carbon where the nucleophilic attack of the halide ion will occur.

With respect to the halogenation of the alkene, the same procedure occurs at the time of the formation of the carbocation, joining the nucleophilic ion to the most substituted carbon.
