Answer:
40 Grams
Explanation:
Fe2O3 is 2 parts Iron 3 parts Oxygen.
Assuming the molecular weights of both are equivalent (<em>ideal elemental law</em>), it is a 2:3 ratio, or 2/5 of the total.
2/5 of 100 is 40, so the answer is
40 grams
Answer:
Solid metals are good conductors of heat and electricity
Explanation:
Answer:
Giant structures are usually arranged in to giant regular lattices and they are extremely strong because they have many bonds involved. Simple molecules are just normal molecules as the name suggests like CO². though it contains strong covalent bond it still has weak intermolecular forces
Explanation: when your account gets to deleted and your trying to get your points up lol
Note that we are omitting the water.
So, sodium carbonate will basically dissociate into positive sodium ions and negative carbonate ions based on the following equation:
<span>Na2CO3 → 2 Na(+) + CO3(2-)
</span>
If we took water into consideration:
Sodium carbonate will dissociate in water forming carbonic acid and sodium hydroxide. Since sodium hydroxide is a strong base, therefore, it will then neutralize the gastric acid, thus, acting as an antacid.
