Answer:
Yes
Explanation:
The combination of an acid and base causes a chemical reaction. The product is a gas, bubbles that are carbon dioxide. The carbon dioxide gas is trapped in the balloon and it inflates. The carbon dioxide gas molecules created a pressure by colliding with the sides of the balloon.
Answer: Option (4) is the correct answer.
Explanation:
Heat of vaporization is defined as the heat energy which is necessarily added to a liquid substance in order to transform the quantity of the substance into a gas.
For example, in there will be presence of strong hydrogen bonding and in order to break this bond high amount of heat energy is required.
Whereas , and are all covalent compounds which are bonded together by Vander waal forces. As these forces are weak in nature hence, they require less amount of heat energy to convert into vapor state.
Hence, they have low value of . Also, Ar is a noble gas and it has only Vander waal forces. So, it will also have low value of .
Therefore, we can conclude that out of the given options have the highest .
P1/T1=P2/T2 Gal Lussac's Law
25 C= 298K (just add 273)
0 C= 273 k
6.00atm/298=P2/273
P2=5.50 atm
Proton, the gold foil experiment indicated that the nucleus has a positive charge.
Answer:
mole
Explanation:
Given parameters:
Mass = 12g
Molecule = Cl₂
Unknown:
Number of moles of molecules = ?
Solution:
To solve this problem, we use the expression below:
Number of moles =
molar mass of Cl₂ = 2 (35.5) = 71g/mol
Number of moles = mole
