In a low pressure system, it is rainy and cold, where as in a high pressure system it is sunny and hot.
hope this helps!! :)
Explanation:
-In NaCl, the sodium ion is the positive one. The chloride ion is the negative one.
-In Ca3P2, the calcuim ion is the positive one. The phosphide ion is the negative one
-In Rb2S, the rubidium ion is the positive one. The sulfide ion is the negative one
-In AlBr3, the aluminum ion is the positive one. The bromide ion is negative
-The K2Se, potassium ion is the positive one. The selenide ion is the negative one
-The BaO, the baruim ion is the positive one. Oxygen ion is the negative one
A cation is a positive charged ion and a anion is a negatively charged ion. An electron will make a cation if it is lost and a anion if it is gained.
The etymology of the prefix cat- means the way down: so think of the sun setting down and losing light. Cat = losing electrons (Such as in a CAThode ray).
The etymology of the prefix -an means upwards. So think of the sun rising up and becoming brighter. An = gaining electrons and becoming overall more negative as electrons are negatively charged.
Answer:
Explanation:
1. Find the molar concentration
Assume that we have 100 mL solution.
Mass of NaCl = 0.90 g
2. Find the osmotic pressure
The formula for osmotic pressure (Π) is
Π = icRT
T = (37 + 273.15) K = 310.15 K
