Higher humidity because there's more H2O in the air
Answer:
There are three factors that help in the prediction of the trends in the periodic table: number of protons in the nucleus, number of energy levels, and the shielding effect. The atomic radii increase from top to the bottom in any group. The atomic radii decrease from left to right across a period.
Explanation:
Major periodic trends include atomic radius, ionization energy, electron affinity, electronegativity, valency and metallic character. These trends exist because of the similar electronic configuration of the elements within their respective groups or periods and because of the periodic nature of the elements.
Answer:
<h2>acetyl chloride > acetic anhydride > methyl acetate > acetamide</h2>
Explanation:
Such kind of substitution reaction in which nucleophiles and the acyl compound interact is known as nucleophilic acyl substitution reaction. In this reaction, the interaction between carbonyl compounds and the nucleophile takes place by addition reaction. The reactivity of the acyl compound is based on the condition of the leaving group that is related to the acidity of the compounds. So the decreasing order of reactivity of the acyl compounds is, acetyl chloride > acetic anhydride > methyl acetate > acetamide.
Answer:
M = 0.138 M
Explanation:
Given data:
Mass of glucose = 12.55 g
Volume of solution = 500 mL
Molarity of solution = ?
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Number of moles of glucose:
Number of moles = mass/molar mass
Number of moles = 12.55 g/ 180.156 g/mol
Number of moles = 0.069 mol
Volume in L:
500 mL × 1 L /1000 mL
0.5 L
Molarity:
M = 0.069 mol / 0.5 L
M = 0.138 M
