What is the highest energy to which doubly ionized helium atoms (alpha particles) can be accelerated in a DC accelerator with 3
pentagon [3]

Answer:

Highest energy will be equal to 9.6\times 10^{-13}J

Explanation:

Charged on doubly ionized helium atom q=2e=2\times 1.6\times 10^{-19}C=3.2\times 10^{-19}C

It is accelerated with maximum voltage of 3 MV

So voltage V=3\times 10^6volt

Now energy is given by E=qV=3.2\times 10^{-19}\times 3\times 10^6=9.6\times 10^{-13}J

So highest energy will be equal to 9.6\times 10^{-13}J

GIVING 20 POINTS!! Apply Concepts Two chemists each plan an investigation in which they will combine hydrogen gas with chlorine
Montano1993 [528]

Answer:

Yes, the investigations will reach similar conclusions about the reactivity of H2 and Cl2

Explanation:

1. The law of multiple proportions says that when elements form compounds, the proportions of the elements in those chemical compounds can be expressed in small whole number ratios.  This means that regardless of whether 1000 times more of the products are used, the reactivity of the products is established by the chemical reaction

2. The law of multiple proportions is an extension of the law of definite composition, which states that compounds will consist of defined ratios of elements.

3. A reaction with more reactants will need more care because more products are produced, which can be toxic

4. H2 and Cl2 reactivity does not depend on the quantities but the chemical properties of each compound

Given what you observe at the molecular/atomic level, why would surface area have this effect?
LenKa [72]

Answer:

Increasing the surface area of a reactant increases the frequency of collisions and increases the reaction rate. Several smaller particles have more surface area than one large particle. The more surface area that is available for particles to collide, the faster the reaction will occur.
