Sean and Rachel we’re both born on April 17.
ipn [44]

Step-by-step explanation:

let Sean be 4 years old and Rachel be 2 years old on April 17

part (A)

R=S-2 --(A)

is an equation that can be used to determine Rachel's age

likewise,

S=R+2--(B)

can be used to determine Sean's age

part (B)

use equation(A) for table (1) and equation(B) for table 2

Table (1) : R=S-2=11-2= R=9

12-2=10=»R=10

13-2=11=»R=11

14-2=12=»R=12

15-2=13=»R=13

16-2=15=»R=14

likewise use equation B for the table (2)

the outputs must be 3,4,5,6,7,8

and 9

A student sets up two reactions. Reaction 1 uses 0.180 mol/L of reactant, and Reaction 2 uses 0.510 mol/L of reactant. How many
il63 [147K]

Given the data from the question, reaction 2 is 2.83 times faster compared to reaction 1

<h3>Data obtained from the question</h3>
  • Molarity of reaction 1 (R₁) = 0.180 mol/L
  • Molarity of reaction 2 (R₂) = 0.510 mol/L
  • Comparison =?

<h3>How to determine the comparison of reaction 2 to reaction 1</h3>

We can determine how many times faster is reaction 2 to reaction by doing the following:

R₂ / R₁ = 0.510 / 0.180

R₂ / R₁ = 2.83

Cross multiply

R₂ = 2.83 × R₁

From the above illustration, we can see that reaction 2 is 2.83 times faster than reaction 1
