Reactants are formed from a chemical bond with can be broken down by vaporizing
Answer:
hi! I'm pretty sure your answer is solvent!
Explanation:
not 100% sure but I looked it up on google. solvent does the dissolving, solute is what is being dissolved, and a solution is the solvent + the solute. hope this helped!
Explanation:
A property which does not bring any change in chemical composition of a substance is known as physical property.
For example, blood is more viscous than water, its pH is slightly alkaline, its temperature is about () .
On the other hand, a property which changes chemical composition of a substance is known as a chemical property.
For example, precipitation, reactivity, toxicity etc are chemical property.
Sometimes, the change in color of a substance can also occur due to a chemical change.
Thus, we can conclude that following are the physical characteristics of blood.
- it is more viscous than water.
- its temperature is about ().
- the pH is slightly alkaline.
- it is about 8% of one’s total body weight.
Mass of Oxygen required : 24 grams
<h3>Further explanation</h3>
Given
3 moles of H
1.5 moles of O
3 moles of H₂O
Required
Mass of O
Solution
Reaction
2H₂ + O₂ ⇒ 2H₂O
Mass of Oxygen for 1.5 moles of O :
= mol x Ar O
= 1.5 moles x 16 g/mol
= 24 grams
