Answer:
2x1000 = 2000
Explanation:
10^3 = 10×10×10 = 1000
exponent , the ^3 means multiply the number by itself 3 times, if it was ^4, it would be 4 times and so forth.
another trick for 10s is just put the 1 and the exponents number of 0's after the 1. so in this case, put three 0's: 1,000
<u>Given:</u>
Concentration of Ba(OH)2 = 0.348 M
<u>To determine:</u>
pOH of the above solution
<u>Explanation:</u>
Based on the stoichiometry-
1 mole of Ba(OH)2 is composed of 1 mole of Ba2+ ion and 2 moles of OH- ion
Therefore, concentration of OH- ion = 2*0.348 = 0.696 M
pOH = -log[OH-] = - log[0.696] = 0.157
Ans: pOH of 0.348M Ba(OH)2 is 0.157
This is a two step step reaction as shown below,
Step 1: Epoxidation of Alkene: In first step Cyclohexene is treated with peroxybenzoic acid in the presence of Dichloromethane which results in the formation of epoxide moiety.
Step 2: Nucleophillic Substitution Reaction: In second step the epoxide formed is treated with Sodium Methoxide which acts as a nucleophile and attacks the less hindered carbon of epoxide resulting in the formation of final product as shown below.
Answer:
Different liquid
Explanation:
<em>The independent variable in the investigation is the different liquid given to the plants.</em>
<u>The independent variable in an experimental investigation is the variable that is supplied by the researcher which directly affects the main variable being measured during the investigation. In other words, the independent variable is a variable that directly affects the dependent variable.</u>
In this case, the dependent variable would be growth determining factors in plants such as height, biomass, number of leaves, etc. while the independent variable would be the different types of liquid given to the plants.
