In order to write the Aluminium electron configuration we first need to know the number of electrons for the Al atom (there are 13 electrons). When we write the configuration we'll put all 13 electrons in orbitals around the nucleus of the Aluminium atom.
A shared derived character is a characteristic or trait that two lineages share.
For example, amphibians, turtles, lizards, snakes, crocodiles, birds and mammals all have, or historically had, four limbs. ... Four limbs is a shared derived character inherited from a common ancestor that helps set apart this particular clade of vertebrates.
Answer:
1514g of CO₂ reacted
Explanation:
Based on the reaction:
2CO₂ + 43.9kJ → 2CO + O₂
<em>2 moles of carbon dioxide require 43.9kJ of energy to produce 2 moles of carbon monoxide and 1 mole of oxygen</em>
<em />
To solve this question, we must convert the 755kJ of energy to moles of carbon dioxide that reacts and to find the mass as follows:
755kJ * (2 moles CO₂ / 43.9kJ) =34.4 moles of CO₂ are produced
<em>Mass CO₂: Molar mass: 44.01g/mol</em>
34.4 moles CO₂ * (44.01g / mol) =
<h3>1514g of CO₂ reacted</h3>
1 lb=453.592 grams
So he gained 453.592 pounds
Answer:
The neck, Tongue, Heart and circulation and Lungs.
Explanation:
The Neck: The total length of the giraffe's neck is 6 feet and carries the muscles of about 550 pounds. But the unique characteristics is that it has same vertebrae as humans have i.e. 7. And to support these heavy muscles at the base of the neck spines are there projecting upwards.
The Tongue: Giraffe has a very avaricious long tongue that helps it to gets different vegetation.
Heart: Surprisingly the heart of the giraffe is small in structure yet powerful. And the blood pressure is quite high, double relatively to human so to pump the blood to its brain along with the long neck.
