Answer:
500 mL
Explanation:
Step 1: Find conversions
1 mL = 0.0338 oz
Step 2: Use Dimensional Analysis
= 500 mL
The Plum Pudding Model is a model of atomic structure proposed by J.J. Thomson in the late 19th century. Thomson had discovered that atoms are composite objects, made of pieces with positive and negative charge, and that the negatively charged electrons within the atom were very small compared to the entire atom.
Answer:
Color change, formation of a precipitate, heat, formation of a gas, and odor
Explanation:
Small peak at 3000large peak at 1685F: it contains two benzene rings that is connected by a bunch of carbons and ketone-Explanation: The spectrum shows a stretching absorption consistent with a ketone functional group: carbonyl C=O stretching at ~1685 cm-1. (An aldehyde, by contrast, would also show a ~2700 cm-1 absorption for the carbonyl C-H stretch.) The C=O stretching frequency is consistent with an aromatic ketone, such as in compound F (1,4-diphenyl-1,4-butanedione). In contrast, an aliphatic ketone absorbs at higher energy (~1710 cm-1). The spectrum also shows the typical ~1600 & ~1500 cm-1 absorptions of a phenyl group.
Answer:
9.15 × 10²³ molecules of N₂O present.
Explanation:
Given data:
number of moles = 1.52 mol
molar mass of N₂O = 44.013 g/mol
number of molecules = ?
Solution:
First of all we will calculate the mass of 1.52 mol.
mass = number of moles × molar mass
mass = 1.52 × 44.013 g/mol
mass = 66.9 g
Now we will find the number of molecules by using Avogadro number,
The number 6.022×10∧23 is called Avogadro number and it is the number of atoms or molecule in one gram atom of an element or one gram molecule of a compound.
44.013 g of N₂O = one mole of N₂O= 6.02 × 10²³ molecules
For 66.9 g:
66.9 g/ 44.013 g × 6.02 × 10²³ molecules
9.15 × 10²³ molecules of N₂O present
