when 10.0 ml of 0.2 m iron(ii) sulfate solution is added to 10.0 ml of 0.2 m iron(iii) nitrate, the resulting concentrations of fe2 and fe3 are
a. 0.2 M and 0.2 M, respectively
b. 0.1 M and 0.1 M, respectively
c. 0.4 M and 0.4 M, respectively
Answers
When 10.0 ml of iron sulphate solution is added to 10.0 ml of iron nitrate the resulting concentration of fe2 and fe3 are b. 0.1 M and 0.1 M, respectively.
First, let's calculate the moles of Fe2+ and Fe3+ ions present in their respective solutions before mixing.
Moles of Fe2+ in iron(II) sulfate solution = (0.2 M)(0.010 L) = 0.002 moles
Moles of Fe3+ in iron(III) nitrate solution = (0.2 M)(0.010 L) = 0.002 moles
Now, combine the solutions by adding the 10.0 mL of iron(II) sulfate solution to the 10.0 mL of iron(III) nitrate solution.
Calculate the total volume of the mixed solution: 10.0 mL + 10.0 mL = 20.0 mL = 0.020 L
Determine the new concentrations of Fe2+ and Fe3+ ions in the mixed solution:
- Concentration of Fe2+ = moles of Fe2+ / total volume = 0.002 moles / 0.020 L = 0.1 M
- Concentration of Fe3+ = moles of Fe3+ / total volume = 0.002 moles / 0.020 L = 0.1 M
So, the resulting concentrations of Fe2+ and Fe3+ in the mixed solution are 0.1 M and 0.1 M, respectively.

C₂H₄O₂ + O₂ ➞ CO₂ + H₂O
Answers
Answer:
C2H4O2 + 2O2 ==> 2CO2 + 2H2O
Explanation:
Start with the carbons
C2H4O2 + O2 ==> 2CO2 + H2O There are 2 on the left, so you need 2 on the right.
Next deal with the hydrogens. You have 4 on the left so you have to make 4 on the right
C2H4O2 + O2 ==> 2CO2 + 2H2O
The oxygens are the real devil in this question. Be careful how you handle them. There are 2 * 2 = 4 from the CO2 and 2*1 = 2 from the water. The total is 6
Now you can't just put a 3 in front of the O2. There are 2 in the given chemical. So you don't need 6. You need 6 -2 = 4. But the oxygen is O2. You have to divide the 4 by 2 to get 2

λ = 2.94 x 10⁹ nm (in nanometers)
λ = 2.94 x 10¹⁰ A (in angstrom)
Explanation:
The wavelength of the radio station can be given as follows:
\(\lambda = \frac{c}{f}\\\)
where,
λ = wavelength = ?
f = frequency = 102 MHz = 1.02 x 10⁸ Hz
c = speed of light = 3 x 10⁸ m/s
Therefore,
\(\lambda = \frac{3\ x\ 10^8\ m/s}{1.02\ x\ 10^8\ Hz}\)
λ = 2.94 m (in meters)
λ = (2.94 m)(10⁹nm / 1 m)
λ = 2.94 x 10⁹ nm (in nanometers)
λ = (2.94 m)(10¹⁰ A / 1 m)
λ = 2.94 x 10¹⁰ A (in angstrom)

e. Water and salts can be re-absorbed and returned to the hemolymph
Answers
The statement about an excretory system consisting of Malpighian tubules is false is:
a. Urine cannot be produced with a U/P of greater than 1.
This statement is false because Malpighian tubules are capable of producing urine with a U/P (urine-to-plasma) ratio greater than 1. The U/P ratio refers to the concentration of solutes in the urine relative to the concentration of solutes in the plasma (blood). Malpighian tubules actively transport nitrogenous waste and other solutes from the hemolymph (insect equivalent of blood) into the tubules, which ultimately leads to the production of urine with a higher concentration of waste products compared to the hemolymph.
The correct statements about an excretory system consisting of Malpighian tubules are:
b. Nitrogenous waste collected is deposited into the gut.
c. KCl is the major ion used in the process.
d. Such a system is found in insects.
e. Water and salts can be re-absorbed and returned to the hemolymph.
In this system, nitrogenous waste products, such as uric acid, are collected by the Malpighian tubules and deposited into the gut, where they can be eliminated from the insect's body. Potassium chloride (KCl) is an essential ion involved in the excretory process, as it plays a role in the transport of waste and water reabsorption. Malpighian tubules are a characteristic feature of the excretory system in insects, and they allow for the reabsorption of water and salts from the tubules back into the hemolymph to maintain proper fluid balance.

c. metallic character decreases as you move across a period from left to right and increases as you move down a group
d. metallic character decreases as you move across a period from left to right and decreases as you move down a group
Answers
The correct answer is c. Metallic character decreases as you move across a period from left to right and increases as you move down a group.
The trend in metallic character across the periodic table is determined by the elements' ability to lose electrons and form positive ions. Metals tend to have low ionization energies and readily lose electrons to form cations, exhibiting metallic properties such as conductivity and malleability.
As you move across a period from left to right, the atomic number increases, resulting in an increasing nuclear charge. This stronger nuclear attraction pulls electrons closer to the nucleus, making it harder for them to be removed, thus decreasing metallic character.
On the other hand, as you move down a group, the principal energy level increases, resulting in a larger atomic radius. The larger atomic size leads to weaker nuclear attraction on outer electrons, making it easier for them to be lost, thus increasing metallic character.
Therefore, metallic character decreases as you move across a period from left to right and increases as you move down a group in the periodic table.

In a laboratory setting, concentrations for solutions are measured in molarity, which is the number of moles per liter (mol/L). Concentrations are often converted to more common units on the labels of household products. For a particular brand of bleach, the concentration of sodium hypochlorite (NaClO) is reported on the bottle as 7.25% by mass. The following information can thus be used to calculate the molarity of NaClO in the bleach:
• 1L of bleach has a mass of 1,100 grams.
• 7.25% of the mass of bleach is NaClO.
• 1 mol of NaClO has a mass of 74.44 grams.
What is the molarity (mol/L) of NaClO in the bleach?
Answers
The molarity of NaClO in the bleach is 0.101 M (mol/L).
Molarity (M) is the number of moles of solute per liter of solution.
It is calculated by dividing the number of moles of solute by the volume of the solution in liters.
To find the molarity of NaClO in the bleach, we need to use the following information given in the question:
1L of bleach has a mass of 1,100 grams7.25% of the mass of bleach is NaClO1 mol of NaClO has a mass of 74.44 gramsTo begin the calculation, we need to determine the mass of NaClO in 1L of bleach.
To do this, we can use the fact that 7.25% of the mass of bleach is NaClO:Mass of NaClO in 1L of bleach = 0.0725 x 1,100 g = 79.75 g
Next, we can convert this mass of NaClO to moles using its molar mass:
moles of NaClO = 79.75 g / 74.44 g/mol = 1.07 mol.
Finally, we can use the formula for molarity to calculate the molarity of NaClO in the bleach:
Molarity = moles of solute / volume of solution in litersMolarity = 1.07 mol / 10 L = 0.107 M (mol/L)We can round this answer to three significant figures to get the final answer of 0.101 M (mol/L).

Answers
the absorbance of the solution in a 1.00cm sample cell at 435 nm is 0.397.
the absorbance of the solution can be calculated using the equation A = εlc,
where l = 1 cm.
We have:
Absorbance of protonated bromothymol blue at 435 nm = ε₁lc
= 13800/Mcm × 2.8 × 10⁻⁵ M × 1 cm
