1. Al(C₂H₅)₂OCl₃
Al(C₂H₅)₂OCl₃ is made from 5 different elements. They are Al, C, H, O and Cl. Number of atoms in each element can be found as follows.
number of Al atoms = 1
number of C atoms = 2 x 2 = 4
number of H atoms = 5 x 2 = 10
number of O atoms = 1
number of Cl atoms = 3
<span>
Total number of atoms = 1 + 4 + 10 + 1 + 3 = 19
2. </span>BCl₃<span>
BCl</span>₃ is a simple neutral molecule. It consists of 2 different elements as B and Cl. Total number of atoms is 4. Number of atoms can be calculated as follows.
number of B atoms = 1
number of Cl atoms = 3
Total number of atoms = 1 + 3 = 4<span>
3. </span>H₂O + H⁺
H₂O makes H₃O⁺ (hydronium ion) with H⁺ which is a positive ion. H₃O⁺ consists of two different elements as H and O. Number of atoms are as follows.
number of H atoms = 3
number of O atoms = 1
Total number of atoms = 3 + 1 = 4
Answer:
High partial pressure of oxygen in the tissues.
Explanation:
Hemoglobin is a protein found in the red blood cells that is responsible for the transportation of oxygen from the lungs to the rest of the tissues in the body. The partial pressure determines whether oxygen is loaded or unloaded into the hemoglobin.
When there is lack of oxygen in our bodies, we experience hypoxia.
Hey there!
First we need to find the molar mass of Ca(OH)₂.
Ca: 1 x 40.078
O: 2 x 16
H: 2 x 1.008
----------------------
74.094 grams
Find how many moles are in 523 grams of Ca(OH)₂.
523 ÷ 74.094 = 7.06 moles
There are 2 atoms of oxygen in each molecule of Ca(OH)₂.
7.06 x 2 = 14.12
523g of Ca(OH)₂ contains 14.12 moles of oxygen.
Hope this helps!
Explanation:
A way to maintain good health is from exercise, eating healthy foods, getting enough rest, keeping .The first mention of the phrase 'you are what you eat' came from the 1826 work Physiologie du Gout, ou Medetations de Gastronomie Transcendante, in which French author Anthelme Brillat-Savarin wrote: “Tell me what you eat and I will tell you what your are.”
