It should be 1.13 x 10^25 atoms
So the question ask that how to prepare 20ml of the liquid mixture having a denstiy of 2.7 g/cm and the best answer, base on the data you have given and further formulation of a solution, the answer would be CHCL3=11.73ml and CHBr3 = 8.268 ml. I hope you are satisfied with my answer
Answer:
Electrons are moved through a magnet, creating a current. That current interacts with a circuit, moving the conductor in the orientation of the field.
Explanation:
Electro magnetic fields are used to create electric current by the movement of electrons. When a coil of wire is wrapped around a magnet it pushes electrons and they flow through a magnet to create current. This current interacts with circuit to move conductor.
Answer:
72g of H2O.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
2H2 + O2 —>2H2O
Next, we'll determine the mass of O2 that reacted and the mass of H2O produced from the balanced equation.
This is illustrated below:
Molar Mass of O2 = 16x2 = 32g/mol
Molar Mass of H2O = (2x1) + 16 = 18g/mol
Mass of H2O from the balanced equation = 2 x 18 = 36g
Summary:
From the balanced equation above,
32g of O2 reacted to produce 36g of H2O.
Now, we can obtain the mass of H2O produced when 64g of O2 react as follow:
From the balanced equation above,
32g of O2 reacted to produce 36g of H2O.
Therefore, 64g of O2 will react to produce = (64 x 36)/32 = 72g of H2O.
From the calculations made above, 72g of H2O is produced from the reaction.
<u>Answer:</u> The parent isotope is undergoing alpha decay.
<u>Explanation:</u>
A nuclear reaction is defined as the reaction in which the changes in the nucleus of an atom take place and usually form a different element. An unstable nucleus undergoes various decay processes to attain stability.
Alpha decay is a type of decay process that happens when a heavy nucleus decays into a light nucleus with the release of an alpha particle. This alpha particle carries a charge of +2 units and has a mass of 4 units. It is also known as the helium nucleus. The general equation for this decay process is:
It is given that the daughter isotope formed has atomic number 2 less than the parent isotope. Thus, it is undergoing alpha decay.
