Answer:
See Explanation
Explanation:
In the equilibrium shown in the question,on the left hand side is a pink hexaaquacobalt II complex which is pink in colour. On the right hand side, we have a tetrachlorocobalt II complex which is blue in colour.
The equilibrium can be shifted from left to right by adding HCl (a source of chloride ions).
Hence, when HCl is added to the system, the equilibrium position is shifted to the right thereby yielding the blue solution of the tetrachlorocobalt II complex.

Balanced equation: K2S(aq) + BaCl2(aq) =
Answer:
K2S(aq) + BaCl2(aq) = 2KCl(aq) + BaS(s)
In the image attached, it is explained how the solution is balanced.
The number of atoms of any element in the given chemical formula is the number that is written on the foot of the symbol of that element. The balanced equation is
K[tex]_2[/tex]S(aq) + BaCl[tex]_2[/tex](aq)[tex]\rightarrow[/tex]2KCl(aq) + BaS(s)
What is Balanced equation?Balanced equation is the one in which the total number of atoms of a species on reactant side is equal to the total number of atoms on product side.
The unbalanced equation is
K[tex]_2[/tex]S(aq) + BaCl[tex]_2[/tex](aq) [tex]\rightarrow[/tex]KCl(aq) + BaS(s)
The number of atoms of K on reactant side is 2 while on product side it is 1, so to balance K we need to multiply KCl by 2
K[tex]_2[/tex]S(aq) + BaCl[tex]_2[/tex](aq) [tex]\rightarrow[/tex]2KCl(aq) + BaS(s)
The atoms of sulfur on reactant and product side is 1, so it is balanced.
The atoms of Ba on reactant and product side is 1, so it is balanced.
The atoms of Cl on reactant and product side is 2, so it is balanced.
Therefore the balanced equation is
K[tex]_2[/tex]S(aq) + BaCl[tex]_2[/tex](aq)[tex]\rightarrow[/tex]2KCl(aq) + BaS(s)

What happens to light as it passes through a convex lens?
A.The light rays bend inward
B. The light scattered
C.The light magnified
D.The light bend outward
Answer:
the answer is D
Explanation:
Rays of light that pass through the lens are brought closer together (they converge). A convex lens is a converging lens. When parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
A mixture contains 21.7 g NaCl,
3.74 g KCI, and 9.76 g Lici.
How many total moles are in this
mixture?
Molar Mass
NaCl: 58.44 g/mol
KCI: 74.55 g/mol
LiCl: 42.39 g/mol
Answer:
[tex]n_{tot}=0.652mol[/tex]
Explanation:
Hello there!
In this case, according to the given problem, it is possible to use the given molar masses of NaCl, KCl and LiCl in order to calculate the total moles, yet we calculate the moles of each salt first as shown below:
[tex]n_{NaCl}=21.7gNaCl*\frac{1molNaCl}{58.44gNaCl}=0.371molNaCl\\\\ n_{KCl}=3.74gKCl*\frac{1molKCl}{74.55KCl}=0.0502molNaCl\\\\ n_{LiCl}=9.76gLiCl*\frac{1molLiCl}{42.39gLiCl}=0.230molLiCl[/tex]
Then, we add them all together to obtain:
[tex]n_{tot}=0.371mol+0.0502mol+0.230mol\\\\n_{tot}=0.652mol[/tex]

Round your answer to one decimal place and enter the number only with no units.
Your Answer:
Answer
Answer:
1.0 mole
Explanation:
From the question given above, the following data were obtained:
Volume (V) = 5 L
Temperature (T) = 205 K
Pressure (P) = 340 KPa
Gas constant (R) = 8.31 KPa.L/Kmol
Number of mole (n) =?
Using the ideal gas equation, the number of mole of the gas in the container can be obtained as follow:
PV = nRT
340 × 5 = n × 8.31 × 205
1700 = n × 1703.55
Divide both side by 1703.55
n = 1700 / 1703.55
n = 1.0 mole
Thus, the number of mole of the gas in the container is 1.0 mole

How many grams would be in 4.45 x 10^23 molecules of N203
Answer:
56.24g
Explanation:
To find the mass of N2O3 in 4.45 x 10^23 molecules, it must first be converted to moles by dividing the number of molecules in N2O3 by Avagadro's number (6.02 × 10^23).
number of moles in N2O3 = 4.45 x 10^23 ÷ 6.02 × 10^23
n = 4.45/6.02 × 10^(23 - 23)
n = 0.74 × 10^0
n = 0.74moles.
Using the formula below to find the mass of N2O3;
mole = mass ÷ molar mass
Molar mass of N2O3 = 14(2) + 16(3)
= 28 + 48
= 76g/mol
mass = mole × molar mass
Mass = 0.74 × 76
Mass = 56.24g
