Hence, Option (A) is correct.

What is States of matter ?

When energy is added or removed to matter in the form of heat, it changes state to form a state of matter.

A state of matter is defined as one of the ways in which matter can interact with itself to form a homogeneous phase.

Therefore , During a change in state, energy is transferred in the form

of heat. Hence, Option (A) is correct.

The relative formula mass (M) of a Group 2 metal carbonate is 197
Relative atomic masses (Ar): C = 12
O = 16
Calculate the relative atomic mass (Ar) of the Group 2 metal in the metal carbonate
Name the Group 2 metal.​

Answers

The relative atomic mass (Ar) : 137 and the element : Ba

Further explanation

The naming of chemical compounds is giving a special name to a compound that aims to facilitate the classification of compounds and facilitate the identification of a compound. The rules for naming chemical compounds have been determined by the IUPAC (International Union of Pure and Applied Chemistry)

This nomenclature includes the naming of ion compounds, covalent compounds, and polyatomic

The molar mass of a compound is given by the sum of the relative atomic mass of Ar  

M AxBy = (x.Ar A + y. Ar B)  

Group 2 metals have a +2 charge : M²⁺

So the compound of metal carbonate : MCO₃

Ar C = 12, O = 16

M MCO₃ = (1.Ar M + 1. Ar C+ 3. Ar O)  

[tex]\tt 197=1. Ar~M+1.12+3.16\\\\197=Ar~M+12+48\\\\Ar~M=137[/tex]

The element with relative atomic masses 137 is Ba

So the compound : BaCO₃

C.

D.

Answers

Answer: A

Explanation: Mortality means death. And it is a primary goal of Development Goals

Reducing child mortality, or rate of death, is one of the primary goals of the UN’s Millennium Development Goals and the correct option is option A.

What is Mortality?

Mortality is defined as the state of the individual being dead. The mortality rate is the death rate of a population which is calculated on the basis of the deaths in the particular region.

Mortality as one of the components of demography is measured as mortality rate.

Mortality meaning provides the basis for mortality rate and its estimation. Mortality is the possibility of and susceptibility to death, and hence, the rate of mortality or the death rate is the measurement of the number of deaths that occur in a particular population, scaled to the size of that population per unit of time.

Therefore, Reducing child mortality, or rate of death, is one of the primary goals of the UN’s Millennium Development Goals and the correct option is option A.

Answers

Answer:

The correct option is;

Element 2

Explanation:

The ionization energy is the energy required to eject an electron from a gaseous ion or atom

The ionization energy increases across the period and increases up the group

The elements with the highest ionization energy are those that have the complete octet structure in their outermost shell, which are the noble gases

Therefore, given that element 2, which has the complete octet structure in the outermost shell, then it is an element of the noble gases which have the highest ionization energy in a period, and therefore has the highest ionization energy.

On the periodic table, the element with 10 electrons is Neon, with ionization energy of 2080.68 kJ/mol which is the second highest after helium, that has only 2 electrons.

pure sodium and chlorine are extremely dangerous, but when combined the result in substance that we use every day. How do you think the properties of sodium and chlorine change when they are combined to make sodium chloride?

Answers

Answer:

Explanation:

chlorine has 7 valence electrons while sodium has 1. on their own, they are very reactive elements. a full valence electron shell has 8 electrons, so when elements combine and have 8 electrons in their outer shell, they are not reactive. when sodium and chlorine are combined to form sodium chloride (table salt), it is no longer dangerous. the number of valence electrons changes its reactivity and how it combines.

The properties of sodium and chlorine change when they are combined to make sodium chloride should be explained below.

Information regarding chlorine:

chlorine comprises of 7 valence electrons while on other hand, sodium has 1.  A full valence electron shell contains the 8 electrons, so when elements combine and have 8 electrons in their outer shell, they are not reactive.

Use the information given to calculate the average atomic mass of element Z. Z- 56 is 70% abundant and Z-59 is 30% abundant.​

Answers

Answer:

56.9 amu

Explanation:

Depending on the number of isotopes an element has, the Average atomic mass of isotopes of an element can be calculated using:

(atomic mass of isotope1 × decimal abundance of isotope1) + (atomic mass of isotope2 × decimal abundance of isotope2)

According to this question, two isotopes of element Z were given

- Isotope Z- 56 with atomic mass 56 is 70% abundance. This means that its decimal abundance is 0.70

- Isotope Z- 59 with atomic mass 59 is 30% abundance. This means that its decimal abundance is 0.30

Therefore, average atomic mass of element Z is:

= (56 × 0.70) + (59 × 0.30)

= (39.2) + (17.7)

= 56.9
