Answer:
<h2>1. Ionic compound-
</h2><h2>2. Polar molecular compound-
</h2>
Explanation:
Mg is a metal that has 12 atomic numbers and thus its electronic configuration is 
. The outer most shell of this element has 2 electrons so it loses 2 electrons and thus form 
ions. Br is a nonmetal and has 35 atomic number so its electronic configuration is 
. Since its outermost shell has 7 electrons so it can accept one electron and thus forms 
. So magnesium ion and bromide ion combine and forms an ionic compound .
P is also a nonmetal and combine with Br with covalent bond and due to electronegativity differences form polar covalent compound such as .
Answer:
The boiling point decreases as the volume decreases.
Explanation:
The Temperature - Volume law otherwise called as Charles law is applied, which says that the volume of the given gas at constant pressure is directly proportional to the temperature measured in Kelvin. As the volume increases, the temperature also increases, if the volume decreases, then the temperature also decreases.
As per the Charles law, here the volume is decreased from 50 ml to 25 ml so the boiling point also decreases.
Answer: 53.3
Explanation:
V2=(T2 x P1 x V1)/(T1 x P2)
(320x50x80)/(300x80)
53.3
B. 0.9 <span>
</span>D.Light intensity has no effect on whether electrons are emitted or not.
and
A. X=1.9eV,Y=0.2eV
I already took the gizmo so I know these are right. The first one I got wrong b/c there was no graph and the last one I didn't understand. Basically for the last one you calculate the work function for the metals and find their difference.
Hope this helps.
In a 0.01 M solution of HCl, Litmus will be red. Litmus paper will turn into red in acidic conditions. Hydrochloric acid is an acid. Litmus is an indicator for acidity and alkalinity made from inchens.
