Based on the atomic-scale models of the samples, which of the following claims do you think is best? Claim 1: All three samples have the same properties. Therefore, they are the same substance. Claim 1: All three samples have the same properties. Therefore, they are the same substance. Claim 2: Two samples have the same properties. Therefore, they are the same substance. However, one sample has a different set of properties. Therefore, this sample is a different substance. Claim 2: Two samples have the same properties. Therefore, they are the same substance. However, one sample has a different set of properties. Therefore, this sample is a different substance. Claim 3: All three samples have different properties. Therefore, they are different substances. Claim 3: All three samples have different properties. Therefore, they are different substances.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

i don't know. if i were you, i would search it up online : d

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.
