An atom is composed of two regions: the nucleus, which is in the center of the atom and contains protons and neutrons, and the outer region of the atom, which holds its electrons in orbit around the nucleus.

dsp73

Answer:

An electrical conductivity meter (EC meter) measures the electrical conductivity in a solution. It has multiple applications in research and engineering, with common usage in hydroponics, aquaculture, aquaponics, and freshwater systems to monitor the amount of nutrients, salts or impurities in the water.

Well all reactions need energy to start it. The light is the energy that the reaction requires to start it. Sunlight also has no mass in the first place so laws of conservation of mass don't apply to it.

Part A Transmutation is the process of transforming one element into another through nuclear reactions. What will be the nuclide

S_A_V [24]

Answer: The isotope produced after the transmutation process of Cf-249 and C-12 is $_{104}^{257}\textrm{Rf}$

Explanation:

Transmutation is defined as the process where one chemical isotope gets converted to another chemical isotope. The number of protons or neutrons in the isotope gets changed.

The chemical equation for the reaction of Californium-249 nucleus with Carbon-12 nucleus follows:

$_{98}^{249}\textrm{Cf}+_6^{12}\textrm{C}\rightarrow _{Z}^{A}\textrm{X}+4_0^1\textrm{n}$

In a nuclear reaction, the total mass and total atomic number remains the same.

To calculate A:

Total mass on reactant side = total mass on product side

249 + 12 = A + 4

A = 257

To calculate Z:

Total atomic number on reactant side = total atomic number on product side

98 + 6 = Z + 0

Z = 104

Hence, the isotope produced after the transmutation process of Cf-249 and C-12 is $_{104}^{257}\textrm{Rf}$
