Because size of an atom INCREASES from top to bottom and DECREASES from left to right on the periodic table. If to elements are in the same period they can't increase in size based on the up or down trend. Instead, notice that Alkali Metals are LEFT of Alkaline Earth Metals. Therefore, the Alkali Metal will be larger than the Alkaline Earth Metals.
Answer:
To find the mass percent of hydrogen in hydrogen chloride, we must divide the weight of the hydrogen atom alone by the weight of the entire molecule. Then we multiply by 100% to find the percentage. Thus, 2.77% of the mass of hydrogen chloride is hydrogen.

Answer:
Vertically Shrunk by a factor of 1/6
Explanation:
Parent Formula: f(x) = a(bx - c) + d
<em>a</em> - vertical shrink/stretch and x-reflections
<em>b</em> - horizontal shrink/stretch and y-reflections
<em>c</em> - horizontal movement left/right
<em>d</em> - vertical movement up/down
Since we are only modifying <em>a</em>, we are dealing with vertical shrink/stretch:
Since a < 1 (1/6 < 1), we are dealing with a vertical shrink of 1/6.
Since a > 0 (1/6 > 0), we do not have a reflection over the x-axis.
Answer:
density is a PROPERTY that DESCRIBES<u> </u>the MASS of an object to its VOLUME.
Explanation:
The correct answer is D. In a police interrogation room, questioning the suspect.
Explanation:
Forensic scientists are experts who use science as part of criminal investigations. Indeed, the main role of these experts is to deal with the evidence related to the crime to help authorities understand how the crime occurred and who was involved in this.
Because of this, the forensic scientist's role includes collecting evidence, analyzing samples, participating as witnesses in trials, and in some cases teach other experts about techniques. However, forensic scientists cannot interrogate suspects as they only deal with evidence and this process is in charge of the police.
