Answer:
robbery
Explanation:
The elements of robbery are 1) the felonious taking of personal property, 2) from the person or immediate presence of another, 3) against the will of the victim, and 4) accomplished by means of force or by putting the victim in fear.
Action of taking property by unlawfully from a person or place by force or threat of force is called robbery and all above condition satisfies the term robbery hence robbery is correct match.
solubility. referring to the ability for a given substance, the solute, to dissolve in a solvent.
Rate = k[A] = first order reaction
<h3>Further explanation</h3>
Given
Rate law
Required
A first-order reaction
Solution
The rate law : equation for the rate of chemical reaction
For reaction
aA + bB ⇒ C
The rate : r = k[A]ᵃ[B]ᵇ
The sum of exponents(a+b) is the reaction order
From the choice :
a. a+b = 2, second order reaction
b. a+b = 3, third order reaction
c. a+b = 4, fourth order reaction
d a+0 = 1, first order reaction
The formula for Aluminium Nitrate is
.
This is because aluminium has a 3+ charge and nitrate has a 1- charge, so you need 3 of them to balance out aluminium.
Therefore, you have
one ion of aluminium.
Answer:
option B is correct : The beam was positively charged.
Explanation:
In 19th century J.J Thomson conducted an experiment on cathode ray tube. These cathode ray tubes were sealed glass tubes inside which the pressure of the gas reduced by evacuating air. Then he applied a high voltage across two electrodes at end of the tube, that voltage caused a beam of particles to flow from the cathode to the anode.
Beam of the particles were originated at the cathode and detected on anode by a phosphorous beyond the anode. As at that time phosphorous sparks and emit light.
To test properties of particles he places two opposite charged electric plates around the cathode rays that is one negative and one positive plate.
Thomson observed that these rays deflected to positive electric plate so it indicated that these rays are composed of negatively charged particles as it was attracted by the positive charged electric plate. These particles later named as electrons.
So,
option B is correct : The beam was positively charged.
