Answer:

b. 4

Explanation:

The reaction expression is given as:

   C₃H₈   +   O₂     →    CO₂   +  H₂O

To solve this problem, we employ a mathematical approach.

Now use coefficient a, b, c and d as the numbers that will balance the expression:

            aC₃H₈   +   bO₂     →    cCO₂   +  dH₂O

Conserving C: 3a  = c  

                   H:  8a  = 2d

                    O: 2b  = 2c + d

let a  = 1, c  = 3, d  = 4 , b  = 5

 The balanced reaction expression is:

            C₃H₈   +   5O₂     →    3CO₂   +  4H₂O

Novosadov [1.4K]

Answer:

Sodium - malleable, soft, and shiny

Silicon - has properties of both metals and nonmetals

Bromine - highly reactive gas

Argon - non-reactive gas

Explanation:

Sodium is an alkaline metal. Just like other alkaline metals, it's malleable, soft, and shiny.

Silicon is a metalloid. Metalloids are elements that have properties of both metals and nonmetals.

Bromine a highly reactive chemical element. It is a fuming red-brown liquid at room temperature that evaporates to form a similarly coloured gas.

Argon is a noble gas. Just like other noble gases, it's non-reactive.

Standard units of measure for density
Mrrafil [7]

Answer:

g/cm³ for solids,

g/ml for liquids

g/L for gases.

Explanation:

Though SI unit of density is kg/m³, for convenience we use g/cm³ for solids, g/ml for liquids and g/L for gases. Mathematically, density is defined as mass divided by volume:   ρ=m/V
