Answer:

(a)57.48 percent (b) 29.45 percent

Explanation:

copper(II) bromide is 29.45 percent copper and 71.54 percent bromine. so the first element percentage composition is always the percentage composition of the compound.

that goes same with sodium hydroxide. it  is 57.48 percent sodium, 40 percent oxygen, and 2.52 percent hydrogen.

Rubbing alcohol or isopropanol can be described by the chemical formula C3H7OH. One milliliter of isopropanol has a mass of 0.76
SVETLANKA909090 [29]

A chemical property of isopropanol : D. Isopropanol is flammable.

<h3>Further explanation </h3>

There are changes that occur in the mater: physical changes and chemical changes

Classification uses the principle of the initial and final state of the substance.

Physical changes do not form new substances, so the properties of the particles remain the same.(size,volume,shape)

Example : boiling and freezing, just change its phase form from liquid to gas or from liquid to solid

 

Chemical changes/reaction form new substances(products) that are different from the initial substances(reactants)

Example : toxic, corroded

So :

  • the physical properties of isopropanol :

<em>mass, density, evaporation</em>

  • the chemical properties of isopropanol :

<em>highly flammable</em>

An atom of sodium -23 has a net charge of +1 identify the number of protons, neutrons, and electrons in the atom. Then explain h
nikitadnepr [17]

Number of protons is 11

Number of neutrons is 12

Number of electrons is 10

For a neutral Na, Sodium atom:

The mass number P+N = 23

Atomic number (E or P) = 11

A charged Na atom that has lost an electron is positively charged and so:  Number of Protons = 11 (Still the same)

Number of neutrons = 12

Number of electrons = 11-1=10 (the atom has lost an electron)

If an atom loses electron, it becomes positively charged ie. P>E
