Because the reaction occurs between a metal and non metal
CL=2,8,7
C
Answer:
4.88 M
Explanation:
M = number moles/Volume (L)
MM AlCl3 = 133.34 g/mol
Volume = 500 mL = 0.5 L
number moles = mass/MM = 325.4/133.34 = 2.44 moles AlCl3
M = 2.44/0.5 = 4.88 M
The accepted model of an atom was made by Schrodinger, which is known as the quantum mechanical model. Unlike Bohr's model, electrons are represented as a cloud and not small balls orbiting the nucleus. There is no define path of electrons in Schrodinger's model, but it can predict the odds of where an electron is located.
The answer to your question is then Electrons form a cloud around the nucleus.
Answer:
Intensity
Explanation:
The correct answer is -Intensity
Reason -
Intensity has no affect on whether or not the photoelectric effect occurs.
As frequency , wavelength are inversely proportional.
Answer:
17 mg/ml.
Explanation:
Since NaOH was titrated against Citric acid in the grape fruit, therefore
Converting g to mg,
0.1698 g * 1000 mg/1 g
= 169.8 mg
Volume of grapefruit juice = 10 ml
Mass of Citric acid in ml of juice = 169.8/10
= 17 mg/ml.
