Answer:
Reliable knowledge is knowledge that has a high probablility of being true because its veracity has been justified by a reliable method. Reliable knowledge is sometimes called justified true belief, to distinguish reliable knowledge from belief that is false and unjustified or even true but unjustified.
Answer: C. HNO3 and NaOH
Explanation:
Arrhenius acid produces hydogen ion (H+) when dissolved in water. An example of Arrhenius acid is HNO3.
Arrhenius base produces hydroxyl ion (OH-) when dissolved water. An example of Arrhenius base is NaOH.
Answer:
0.225 atm
Explanation:
v1=450ml÷1000=0.45l(1l=1000ml)
P1=1
v2=2.00l
p2=?
p1v1=p2v2
p2=p1v1/v2
=1×0.45/2
=0.225
so the answer is first one
Answer:
B. The s orbital and two p orbitals
Explanation:
Answer:
210 moles
Explanation:
From the question given above, the following data were obtained:
Volume of solution = 25.6 L
Molarity = 8.20 M
Mole of solute =?
Molarity is simply defined as the mole of solute per unit litre of water. Mathematically, it can be expressed as:
Molarity = mole /Volume
With the above formula, the mole of solute dissolved can be obtained as follow:
Volume of solution = 25.6 L
Molarity = 8.20 M
Mole of solute =?
Molarity = mole /Volume
8.20 = mole / 25.6
Cross multiply
Mole = 8.20 × 25.6
Mole = 209.92 ≈ 210 moles
Thus, the mole of solute dissolved in the solution is 210 moles
