Answer: A. Gamma Ray
Explanation:
X-ray scans can diagnose possibly life-threatening conditions such as blocked blood vessels, bone cancer, and infections. However, x-rays produce ionizing radiation—a form of radiation that has the potential to harm living tissue. However, the risk of developing cancer from radiation exposure is generally small.

Answer:
The statement is TRUE.
Explanation:
In endothermic reactions, heat is absorbed (imagine that heat would be a reactive in the reaction). The enthalpy (H) of the products is greater than that of the reagents and the deltaH is positive. An example of this reaction is the decomposition of H20:
2H20 -> 2H2 + 02
It looks like we are solving for a pressure. All that is required is some algebraic manipulation to find our pressure in mmHg.
Given:
(5.0 m³)(7.5 mmHg) = (P)(4.0m³)
Multiply:
37.5 = 4.0P
Divide:
9.375 = P
P = 9.4 mmHg (remember sig figs)
<h3>
Answer:</h3>
9.4 mmHg
This statement is true in fact to mount Everest atmospheric pressure sit at about one third of that at sea level.
Answer:
4) 2Na + Cl2 → 2NaCl
5) 2Mg + O2 → MgO
6) 2H2 + 2O2 → 2H2O
Explanation:
4) In order for it to be well balanced, yeah you've got to add 2 in front of Na before the reaction and after the reaction.
5) Add 2 in front of Mg bcuz of the same reason in number 4 but you don't have to add 2 in front of the others bcuz it's alrd well balanced.
6) Tbh for this one, it got me staring at my cat until he freaks out but like yeahh, I tried :')
