<u>Answer:</u> The gamma decay is represented below.

<u>Explanation:</u>

Gamma decay is defined as the process in which an unstable nuclei gives off excess energy by a spontaneous electromagnetic process and thus releases \gamma -radiations. These radiations does not carry any charge and are electrically neutral.

The chemical equation representing gamma decay process follows:

_Z^A\textrm{X}^*\rightarrow _Z^A\textrm{X}+_0^0\gamma

where,

_Z^A\textrm{X}^* = unstable nuclei

_Z^A\textrm{X} = stable nuclei

_0^0\gamma = gamma particle

Hence, the gamma decay reaction is given below.

In which are the ionic solids ranked in order of increasing melting point?
abruzzese [7]

Answer:A

Explanation:

The melting points of solids depend in the relative sizes of ions in the ionic lattice. The smaller the relative sizes of the ions, the higher the lattice energy and the stronger the lattice hence higher melting point. Comparing relative ionic sizes, fluoride ion is lesser in size than chloride ion hence NaF has a higher melting point than NaCl.

A student determines the molar mass of acetone, CH3COCH3, by the method used in this experiment. She found that the equilibrium
Alexandra [31]

Answer:

(a). 4°C, (b). 2.4M, (c). 11.1 g, (d). 89.01 g, (e). 139.2 g and (f). 58 g/mol.

Explanation:

Without mincing words let's dive straight into the solution to the question.

(a). The freezing point depression can be Determine by subtracting the value of the initial temperature from the final temperature. Therefore;

The freezing point depression = [ 1 - (-3)]° C = 4°C.

(b). The molality can be Determine by using the formula below;

Molality = the number of moles found in the solute/ solvent's weight(kg).

Molality = ( 11.1 / 58) × (1000)/ ( 90.4 - 11.1) = 2.4 M.

(c). The mass of acetone that was in the decanted solution = 11.1 g.

(d). The mass of water that was in the decanted solution = 89.01 g.

(e). 2.4 = x/ 58 × (1000/1000).

x = 2.4 × 58 = 139.2 g.

(f). The molar mass of acetone = (12) + (1 × 3) + 12 + 16 + 12 + (1 x 3) = 58 g/mol.

Virtually no chemical reaction can occur in the body in the absence of enzymes. how might excessively high body temperature or a
olchik [2.2K]
1. The structural unit of nucleic acids are composed of repeating units of monomers called nucleotides. Nucelotides are composed of three functional groups: sugars which are specifically pentoses (5-Carbon sugars), phosphate group and nitrogenous base.

2. The two major classes of nucleic acids in the body are the DNA or deoxyribonucleic acids and RNA or ribonucleic acids.

3.
a. Based on the nitrogenous bases and sugar, the DNA has a deoxyribose as the sugar and its 4 bases are adenine, guanine, cytosine and thymine. For RNA, the sugar is ribose while its 4 bases are <span>adenine, guanine, cytosine, and uracil

b. Based on the </span>general three-dimensional structure, DNA is a double stranded β-helix with a long chain of nucleotides. RNA is composed of a shorter chain with a single strand α-helix structure.

c. Based on r<span>elative functions, the DNA is responsible for storing the genetic information while the RNA is responsible for transporting the genetic information to the ribosomes which synthesize proteins.</span>

13C and 14C are isotopes of 12C, which has 6 electrons, 6 protons, and 6 neutrons. What is the arrangement of subatomic particle
Degger [83]
6 electrons, 6 protons, and 8 neutrons.
This is because in isotopes of the same element proton and electron number are the same, it is only the number of neutrons that changes.

What does elevation effect on climate
HACTEHA [7]
The higher in altitude the colder the temperature. Temp. drop 4°F every 1000 feet. That means that 75° at the bottom and 10000 feet up it will be 35°. This colder temp does affect plant growth but it also affects the soil which in turn affects plant growth. Mountain vegetation (depending on the elevation) is comparable to the vegetation in areas of high latitude. Areas found up in the northern regions are affected by the colder temp as are the soils - same happens in mountainous areas. You tend to see more evergreens and soils are more acidic and less rich (poor nutrients). You will also get your permafrosts. Eventually a treeline occurs - mountain tops become treeless as does the north arctic areas. You find mosses growing in and around the rocks with some shrubs whereever there is enough soil for the roots to take. "An increase in altitude, such as climbing a mountain is similar to heading north (in the northern hemisphere) plant and animal species will be similar at a mountain top to those which are further north.
