Which of the following is an oxidation-reduction reaction? ZnS(s) + 2O2(g) ZnSO4(s) CaO(s) + H2O(l) Ca(OH)2(s) 6Li2O(s) + P4O10(g) 4Li3PO4(s) SO2(g) + H2O(l) H2SO3(aq)

Answers

ZnS(s) + 2O₂(g) ⇒ZnSO₄(s)

Further explanation

The oxidation-reduction reaction or abbreviated as Redox is a chemical reaction in which there is a change in oxidation number

Oxidation is an increase in oxidation number, while reduction is a decrease in oxidation number.

Reaction

ZnS(s) + 2O₂(g) ⇒ZnSO₄(s)

S²⁻ (-2 in ZnS) to S⁺⁶(+6 in ZnSO₄) ⇒ oxidation

O₂(0 in O₂) to O⁻²(-2 in ZnSO₄)⇒ reduction

The speed limit on a certain highway is 80 kilometers per hour. What is this speed in centimeters per second?

Answers

The speed : 2222.2 cm/s

Further explanation

Velocity has magnitude and direction  

Can be formulated :

[tex]\tt \boxed{\bold{v=\dfrac{d}{t}}}[/tex]

v= velocity, m/s

d=distance=m

t=time,s

convert from km/h to cm/s :

[tex]\tt =80\dfrac{km}{h}\times \dfrac{10^5~cm}{1~km}\times \dfrac{1~h}{3600~s}\\\\=2222.2~\dfrac{cm}{s}[/tex]

Double Displacement reaction

A gas occupies 4.31 liters at a pressure of 0.755 atm. Determine the volume if the pressure is increased to 1.25 atm. (Boyle)

Answers

Answer:

2.60 L

Explanation:

The new volume can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we are finding the new volume

[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]

From the question we have

[tex]V_2 = \frac{4.31 \times 0.755}{1.25} = \frac{3.25405}{1.25} \\ = 2.60324[/tex]

We have the final answer as

2.60 L
