Classify the following as atoms or molecules. Drag the appropriate items to their respective bins. a. Mg S b. H2 SO3 c. HBr
Harman [31]

Answer:

a) Mg and S = atoms

b) H2   SO3 = molecules

c) HBr =molecule

Explanation:

Step 1: Data given

Atoms = An atom is the smallest constituent unit of ordinary matter that constitutes a chemical element. We can find them on the periodic table.

Molecules = A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.

a. Mg S  = Magnesium and sulfur both are atoms, we both can find them on the periodic table

b. H2 SO3  =  H2 is a molecule that contains 2 hydrogen atoms

SO3 is a molecule that contains 1 sulfur atoms and 3 oxygen atoms

c. HBr = HBr is a molecule that contains 1 hydrogen and 1 bromine atom

Arrhenius acids are 1. substances that produce hydrogen atoms in solution. 2. substances that produce hydronium ions in aqueous
ElenaW [278]

Answer:

<h2>1 ) substances that produce hydrogen atoms in solution.</h2>

Explanation:

A swedist scientist Savante Arhenius give the theory of behaviour of Acid-bases. According to Arhenius ,Arhenius Acid compound produce hydrogen ion or proton upon adding in aqueous solution . Acid are molecular compound that have higly polar covalently bonded  ionizable hydrogen atom. HCL is a polar covalently bonded and gas at room temperature and noormal pressure . Upon addition of HCL in water cause ionization ,water breaks into chloride ion and hydrogen ion , in this reaction chlorine gain bond pair electron , while hydrogen ion or proton attached with water . chlorine gain bond pair electron due higher electronegativity than hydrogen and hydrogen loose their electron due to less electronegativity and become hydrogen ion ,these hydrogen ion attached with water to form hydronium ion H_{3}O^{+}(aq) . Hydronium ion is polyatomic ion .

  • Ionization of HCL in water  

         HCL(gas)\rightarrow H^{+}(aq) + CL^{-}(aq)

  •  formation of polyatomic hydronium ion after HCL ionization in water ,where hydrogen ion attached to water and form polyatomic ion.

                 HCL(gas) + H_{2}O(liq)\rightarrow  H_{3}O^{+}(aq) + CL^{-}(aq).

Radioactive decay Question 6 options: is a spontaneous process. occurs when an unstable nucleus loses energy. does not require a
lianna [129]

The correct answer is all of the above.  

Nuclear or radioactive radiation or radioactive decay refers to the procedure by which an unstable atomic nucleus loses energy in the form of mass in its rest frame by discharging radiation like a beta particle, alpha particle, or a gamma ray. A substance comprising such unstable nuclei is regarded as radioactive. The process does not need any input of energy.
