D
Molecules consist of multiple atoms put together to create a new form.
Answer:
See explanation and image attached
Explanation:
The reaction of bromine molecule with an alkene passes through a bridged intermediate known as the brominium ion.
It is a cyclic intermediate that contains a positively charged bromine ion as i have shown in the image attached.
The brominium ion is first formed during the bromininaton of alkenes.
Answer:
96 grams
Explanation:
Density = mass / volume Multiply both sides by the volume
density * volume = mass
mass = 8 g / cm^3 * 12 cm^3
mass = 96 grams
Answer:
A) Precision
B) Accuracy
C) Precision
D) Accuracy
Explanation:
<em>Accuracy</em> and <em>Precision </em>are factors that determine whether a given analysis is appropiate or not.
Accuracy refers to how close the experimental result is to a <em>known, theoretical or accepted value. </em>For this reason every method that checks the accuracy uses a standard -this could mean repeating the test using the standard instead of the sample, or adding a known amount of analyte to the sample-, in order to compare the results.
Precision refers to how close repeated the results of different tests are to each other, in other words, it refers to the <em>repeatability </em>of the method. A test for precision would require that the method is done several times, in order to check how close the results are to each other, regardless of whether those results are close to the expected value.

Actually Welcome to the Concept of the Chemistry.
The reaction that Is opposite of the decomposition is
==> Synthesis Reaction.
==> Catalyst always Speeds up any reaction, so that it quickly reaches to it's Equilibrium point and gets stabilize.
