Answer:
duplet-A set of two things or people
Octet-A group of 8 things or people
Answer:
83.33ml
Explanation:
Firstly, let's notice that 200ml are equal to 0.2L
M=number of moles of the solute ÷ number of liters. Let's call the number of liter by x:
2.5=x÷0.2
x=2.5×0.2
x=0.5
It means you'll need 0.5 mol of HNO. But your solution have 6 moles per liter, so how much do you need? Divide the moles by 12 to have 0.5, so now you need to divide the liter per 12 too. The liter is equal to 1000ml, so:
1000ml÷12=83.33ml

Hello there!
In this case, since the the concentrations are not given, and not even the Ksp, we can solve this problem by setting up the chemical equation, the equilibrium constant expression and the ICE table only:
Next, the equilibrium expression according to the produced aqueous species as the solid silver chloride is not involved in there:
And therefore, the ICE table, in which x stands for the molar solubility of the silver chloride:
I - 0 0
C - +x +x
E - x x
Which leads to the following modified equilibrium expression:
Unfortunately, values were not given, and they cannot be arbitrarily assigned or assumed.

Answer:
2.61atm
Explanation:
The following were obtained from the question given:
P1 = 2.1atm
T1 = 21°C = 21 + 273 =294K
T2 = 93°C = 93 + 273 = 366K
P2 =?
Using P1/T1 = P2/T2, we can calculate for the new pressure as follows:
P1/T1 = P2/T2
2.1 / 294 = P2 / 366
Cross multiply to express in linear form
294 x P2 = 2.1 x 366
Divide both side by 294
P2 = (2.1 x 366) / 294
P2 = 2.61atm
