Answer:
a. forming ions, causing reactions that mutate DNA
Explanation:
Ionizing radiation is a type of energy released by atoms in the form of electromagnetic waves or particles. The spontaneous decay of atoms is called radioactivity, and the surplus energy emitted is a form of ionizing radiation. The unstable elements that decay and emit ionizing radiation are called radionuclides.
Exposure of a human being to certain doses of ionizing radiation can cause irreparable changes in the structure of their DNA, that is, in the genes that control the function of cells, and therefore cause a series of changes that can lead to a cancer.
Answer:
Explanation:
The oxidation reduction reactions are called redox reaction. These reactions are take place by gaining or losing the electrons and oxidation state of elements are changed.
Oxidation:
Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.
Reduction:
Reduction involve the gain of electron and oxidation number is decreased.
Oxidizing agents:
Oxidizing agents oxidize the other elements and itself gets reduced.
Reducing agents:
Reducing agents reduced the other element are it self gets oxidized.
In given example,
Magnesium is able to <u>reduced</u> the copper and copper is able to <u>oxidized</u> the magnesium.
Zinc is able to <u>oxidized</u> the magnesium and magnesium is able to <u>reduced</u> the zinc.
Copper is able to <u>oxidized</u> the zinc and zinc is able to <u>reduced</u> the copper.
Answer:
You need to heat the mixture to 78.37°C
Explanation:
In distillation, you can separate 2 or more compounds based on their difference in boiling points.
In a mixture of ethanol and water, in theory, you need to heat the mixture to 78.37°C. In this temperature, the ethanol must be evaporated and then condensed in the receiving flask.
One half-life: 5 grams
Two half-lives: 2.5 grams
Answer:
at 181.0 
is -723.3 kJ/mol.
Explanation:
We know, 
where, T is temperature in kelvin.
Let's assume 
and 
does not change in the temperature range 25.0 - 181.0 .
= (273+181.0) K = 454.0 K
Hence, at 181.0 , ![\Delta G^{0}=(-795.8kJ/mol)-[(454.0 K)\times (-159.8\times 10^{-3}kJ/K.mol)]](https://tex.z-dn.net/?f=%5CDelta%20G%5E%7B0%7D%3D%28-795.8kJ%2Fmol%29-%5B%28454.0%20K%29%5Ctimes%20%28-159.8%5Ctimes%2010%5E%7B-3%7DkJ%2FK.mol%29%5D)
= -723.3 kJ/mol
