Answer:

Infrared radiation lies between the visible and microwave portions of the electromagnetic spectrum. Infrared waves have wavelengths longer than visible and shorter than microwaves, and have frequencies which are lower than visible and higher than microwaves

C) The atom must contain some centrally located positive charge. He called this core of positive charge the nucleus.

Explanation:

Rutherford concluded from his experiment that the atom contains some centrally located positive charge. He called the core the nucleus.

Rutherford developed the nuclear model of the atom.

In a bid to explain his observation, Rutherford suggested the nuclear model.
The model consists of small positively charged center called the nucleus.
Nearly all the mass is concentrated in the nucleus.
The extranuclear space is made up of electrons orbiting the nucleus.

g Reduction involves the A) loss of neutrons, gain of electrons, and an increase in oxidation state. B) loss of neutrons. C) inc

artcher [175]

Answer:

E. Gain of electrons

Explanation:

A reduction reaction is one part of the two concurrent reactions that take place in a redox (reduction-oxidation) reaction.

During reduction, an atom gains electrons from a donor atom, and it's oxidation number becomes smaller.

Option A is wrong because reduction does not increase oxidation state nor are neutrons involved

Option B is wrong because reduction is not a nuclear reaction (does not involve the nucleons)

Option C is wrong because reduction leads to reduction in oxidation state

Option D is wrong leads to a reduction in oxidation state when electrons are gained

Option E is correct because reduction involves gain of electrons

A sample of 40.0 mL of hydrogen is collected by water displacement at a temperature of 20 degrees Celcius. The barometer reads 7

Roman55 [17]

Answer : The volume of the hydrogen at STP is, 36.8 mL

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas = 751 torr

$P_2$ = final pressure of gas at STP = 760 torr

$V_1$ = initial volume of gas = 40.0 mL

$V_2$ = final volume of gas at STP = ?

$T_1$ = initial temperature of gas = $20^oC=273+20=293K$

$T_2$ = final temperature of gas at STP = $0^oC=273+0=273K$

Now put all the given values in the above equation, we get:

$\frac{751torr\times 40.0mL}{293K}=\frac{760torr\times V_2}{273K}$

$V_2=36.8mL$

Therefore, the volume of the hydrogen at STP is, 36.8 mL
