Answer: 6.3 kg m/s toward pitcher
Explanation:
Answer:
The correct answer is C: A radiation consisting of uncharged particles is emitted when alpha particles strike beryllium atoms.
Explanation:
Chadwick discovered neutron while experimenting with a gold foil. A stream of alpha particles produced from a polonium source was directed at beryllium target. It was noticed that some penetrating radiations were produced. These uncharged particles were called neutrons because on the charge detector these particles showed no deflection.
Their nuclear reaction is as follow.
₂He + ₄Be ----------> ₀n + ₆C
Chadwick noticed that neutrons cannot ionize gases and are highly penetrating particles.
Answer:
1. Ag+ precipitates. 2. Ca2+ precipitates. 3. Co2+ precipitates.
Explanation:
First AgBr is formed which is practically insoluble in water. CaBr2 and CoBr2 are soluble.
Then precipitates CaSO4. CoSO4 is soluble.
And then precipitates Co2(PO4)3 which is insoluble.
Answer:
The final concentration of the Randyne in grams per milliliter = 0.011 g/mL
Explanation:
As we know
C1V1 = C2V2
C1 and C2 = concentration of solution 1 and 2 respectively
V1 and V2 = Volume of solution 1 and 2 respectively
Substituting the given values, we get -
mg/mL
The final concentration of the Randyne in grams per milliliter = 0.011 g/mL
