A cylinder with a radius of 5.6 cm and a height of 10.7 cm has what volume? (You can look up the formula for the volume of a cyl

Keith_Richards [23]

Answer:

$V=1054.2cm^{3}$

Explanation:

1. First take the cylinder volume formula:

$V=\pi.r^{2}.h$

2. Then take the values for the radius and the height of the cylinder and replace them into the formula:

$V=\pi*(5.6cm)^{2}*(10.7cm)$

3. Solve the equation:

$V=\pi*(31.36cm^{2})*(10.7cm)$

$V=\pi*335.5cm^{3}$

$V=1054.2cm^{3}$

Write a nuclear reaction for the neutron-induced fission of u?235 to produce te?137 and zr?97. how many neutrons are produced in

alexandr1967 [171]

This is a neutron induced fission, therefore a neutron will be added to the U²³⁵ to cause the reaction, and thus it will be added to the left side. There will be unknown number of neutrons produced and thus we put this on the right hand side.
n₁ + U²³⁵ = Te¹³⁷ + Zr ⁹⁷ + xn1 ( n1 to mean a neutron of mass 1)
To balance the masses on both sides of the equation;
1 + 235 = 137 +97+ x
x = 2
the end reaction will be
n₁ +U²³⁵ = Te¹³⁷ + Zr⁹⁷ + 2 n₁

Which unit can be used to express the concentration of a solution?

exis [7]

Answer: (3) ppm

Explanation: Concentration is defined as the amount of solute dissolved in a known amount of the solvent or a solution.

Parts per million (ppm) is used to express the concentration when a very small quantity of solute is present in a large quantity of the solution. It is defined as the mass of solute present in one milion $(10^6)$ parts by mass of the solution.
