The molality is calculated using the following rule:
molality = number of moles of solute / kg of solvent
From the periodic table:
molar mass of lithium = 6.941 gm
molar mass of chlorine = 35.453 gm
molar mass of LiCl = 6.941 + 35.453 = 42.394 gm
number of moles found in 42 gm = mass / molar mass = 42 / 42.394 = 0.99
molality = 0.99 / 3.6 = 0.275 m
Answer:
2. +7
Explanation:
The oxidation state of Cl in `HClO_(4)` is +7.Apr 17, 2022
3ans. CrS+2No3 --) 2No+So4+cr^3+
Cr=1 Cr=1
S=1 S=1
N=1=2 N=1=2
O=3=6 o=5=6
now that is how it look and it is not balanced in oxygen so add 2 in the front of No3.
it will look something like this 2NO3. even if u add 2 in the fornt it is not balance so add again 2 in the No in second and it will look like this 2NO.
so now it is blance.
Answer:
<h3><em>What is filteration</em><em>:</em></h3>
Filtration, the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles. ... In some processes used in the production of chemicals, both the fluid filtrate and the solid filter cake are recovered.
<h3><em>When</em><em> </em><em>do</em><em> </em><em>we</em><em> </em><em>use</em><em> </em><em>it</em><em>:</em></h3>
<em>Filtration is used to separate particles and fluid in a suspension, where the fluid can be a liquid, a gas or a supercritical fluid. Depending on the application, either one or both of the components may be isolated.</em>
<h3><em>In</em><em> </em><em>order</em><em> </em><em>to</em><em> </em><em>separate</em><em> </em><em>a</em><em> </em><em>salt-water</em><em> </em><em>mixture</em><em>,</em></h3><h3><em>should</em><em> </em><em>a</em><em> </em><em>student</em><em> </em><em>use</em><em> </em><em>filtration</em><em>:</em></h3>
The mixture can be separated by filtration, by dissolving the mixture in water. Salt will dissolve in the water, whereas sand will not.

I believe it would be A, frogs and spiders, because frogs and spiders both eat grasshoppers. But I cannot see the diagram it talks about, so it's harder to tell.
