Permeable materials for what
Answer:
0.02L
Explanation:
Using the formula V1/T1 = V2/T2
Given
V1 = 0.5L
T1 = 25 degrees
T2 = 1 degree
V2 =?
Substitute
0.5/25 = V2/1
Cross multiply
25V2 = 0.5
V2 = 0.5/25
V2 = 0.02L
Hence the new volume will be 0.02L
The atomic number of an atom containing 29 protons, 29 electrons, and 34 neutrons is 29.
The atomic number of copper is 29, and it has a mass number of 63. The mass number is generally equal to the sum of the protons as well as neutrons within the nucleus, while the atomic number refers to the count of the nucleus's protons. This indicates that the nucleus of the copper atom contains 34 neutrons as well as 29 protons, for a total of 63 protons.
The charge number of such an atomic nucleus would be the chemical element's atomic number, also known as the nuclear charge number. This is equivalent to the proton number, or even the quantity of protons present in the nucleus of each atom of a particular element, for conventional nuclei.
Therefore, the atomic number of an atom containing 29 protons, 29 electrons, and 34 neutrons is 29.

White gold is yellow gold that has had other alloys added to it to make it appear white. New polished white gold has a bright white metal color. Depending of the type of alloys used in the fabrication of white gold, white gold jewelry tends to have a faint yellowish tint with wear.
Answer:
Explanation:
Iodine - 125
The atomic symbol of iodine is ¹²⁵₅₃ I
The symbol for iodine is I
The atomic number of iodine is 53,
and the atomic mass of iodine is 125 .
<u>The representation of the atomic symbol is as, the atomic mass is written in uppercase and the atomic number is written in lower case , followed by the symbol of the element .</u>
Iodine is a radio active element , used for many biological process .
It is the second largest -lived radioisotope of iodine .
The first is iodine-129 .
