Answer:

Diffusion is the movement of solutes from an area of higher concentration to an area of low concentration.

Explanation:

In chemistry, diffusion is the movement of molecules or atoms from an area of higher concentration to an area of low concentration. How it works is that molecules in motion from thermal energy randomly move about. Over time, this leads to the distribution of different particles in your volume solution.

A lithium atom contains 3 protons,4neutrons and 3 electrons.What would be formed if a proton was added to this atom.

slega [8]

Answer:

Adding one proton to an atom of lithium with 3 protons, 4 neutrons and 3 electrons would form a _beryllium ion_. The new atom have 4 protons and 4 neutrons since Be has a mass number of 9 then it has to form an ion. Hope this helps! PLEASE GIVE ME BRAINLIEST!!!! =)

ClO(4)− Express your answer as a chemical formula.

Nimfa-mama [501]

ClO(4)− is regarded as perchlorate ion and are produced commercially in most situations as salts via industries and in the laboratory.

<h3>What is Perchlorate ion?</h3>

This ion is referred to as a monovalent inorganic anion and is obtained by deprotonation of perchloric acid. It is composed of chlorine and oxygen atoms in the ratio 1 to 4 respectively.

This has 32 valence electrons available in the Lewis structure and is used in the commercial production of solid rocket fuel.This ion has a molar mass of 99.451 g mol−1 and is used in different processes such as an oxidizer and to control static electricity during the process of food preservation in industries.

Therefore ClO₄− is also regarded as perchlorate ion and is the most appropriate choice.

SVEN [57.7K]

Answer:

Functional groups

Explanation:

A functional group refers to an atom or cluster of atoms that are covalently bonded to carbon and influence the behavior of organic compounds.

There are several functional groups in organic chemistry that determine the properties of organic compounds.

For instance, in the compound CH3CH2CH2CH2OH, the functional group is the -OH group. The chemical and physical properties of this compound is largely determined by this functional group.

A given reaction has an activation energy of 24.52 kj/mol. at 25°c, the half-life is 4 minutes. at what temperature will the hal

igor_vitrenko [27]

According to half life equation:

T(1/2) = ㏑2 / K1

when the T(1/2) = 4 min * 60 = 240 sec

by substitution:

240 = 0.6931 / K1

K1 = 2.9 x 10^-3

when the second T(1/2) = 20 sec, so to get K2:

T(1/2) = 0.6931 / K2

by substitution:

20 = 0.6931 / K2

∴K2 = 3.4 x 10^-2

so, we can get T2 by using this formula:

㏑ (K2/K1) = Ea/R (1/T1 - 1/T2)

by substitution:

㏑(3.4 x 10^-2)/(2.9 x 10^-3) = (24520 / 8.314) (1/298 - 1/T2)

∴ T2 = 396.7 K

= 396.7 - 273 = 123.7 °C
