Element Q is an element that has a metallic shininess, has good heat conductivity, and is very brittle. To which of the following categories does Element Q most likely belong? O A. compounds B. metalloids C. metals D. nonmetals

C. metals

Explanation:

Elements in the periodic table are grouped into metal and non-metals depending on their characteristics. Metals usually possess the following characteristics:

- High melting and boiling point

- Brittle i.e. ability to break

- lustre i.e. ability to shine when polished.

- Good conductor of heat and electricity

Based on this above characteristics, element Q in this question is a METAL because it posseses the same qualities that a metal does.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.  

"it built up in the atmosphere"

i think thats it, idk, i tried looking for this exact q& a for grad. and idk if i got this question right or sorry if im wrong
