Answer:
Some common examples of malleable metals are; gold, iron, silver, aluminium, copper, lead, etc. Sometimes, the hard metals make it harder to be deformed into thin sheets. ... Thus, argon does not show the property of malleability.
Answer:
Molarity=Moles of solute/volume of solution in Litres
Simply imputing your values
you have
0.75/65
0.0115M.
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>
Answer:
The answer to your question is: H₂CO₃ is a strong acid
Explanation:
HCl is a strong base. This option is wrong because HCl is a strong acid.
Water is a strong acid. Water is a neutral substance it is neither an acid nor a base.
HCO 3 is a strong acid. I can see clearly the molecule but if it were H₂CO₃ , it would be carbonic acid which is a strong acid, but if not, this aswer is wrong.
Ammonia is a strong base. This answer is incorrect, Ammonia is a weak base.
