Answer:
Electrons- 95
Protons- 95
Neutrons-146
Explanation:
An atoms is made up of three fundamental particles; electrons, protons and neutrons,
Americium belongs to the f block in the periodic table. It is an actinide element.
An atom of Am-241 contains 95 protons, 95 electrons and 146 neutrons.
Everything has chemical properties it depends on the reactivity and the reactivity of the other element and what form it is in
Answer:
0.75L
Explanation:
To get the number of liters of hydrogen gas produced, it is very essential to get the number of moles of hydrogen gas produced.
The number of moles of hydrogen gas produced is obtainable and accessible from
the number of moles of zinc reacted.
Hence, we will get the number of moles of zinc reacted at first. To get the number of moles of zinc reacted, we divide the mass of the zinc by the atomic mass of the zinc metal which is 65.38 amu
The number of moles of the zinc is thus: 2.2/65.38 which equals 0.03365 mole
From the equation of chemical reaction, it can be seen that one mole of zinc metal yielded one mole of hydrogen gas. Hence, it is expected that 0.03365mole of zinc will yield 0.03365mole of hydrogen gas.
Now, we proceed to get the volume of the hydrogen gas produced. We know quite well that at S.T.P a mole of a gas occupies a volume of 22.4L. Hence , 0.03365 mole will occupy a volume of 22.4 * 0.03365 which equals 0.75L
