A solution of hydrogen peroxide, H2O2, is titrated withpotassium permanganate, KMnO4, according to the following equation: 5H2O2 + 2KMnO4
+ 3H2SO4 = 5O2 + 2MnSO4 + 8H2O + K2SO4. It requires 46.0 mL of 0.145 Mol/L
KMnO4 to titrate 50.0 mL of the solution of H2O2. What is the mole per liter
concentration of H2O2 in the solution?

Answers

5H2O2 + 2KMnO4+ 3H2SO4 = 5O2 + 2MnSO4 + 8H2O + K2SO4

0,145 moles of KMnO4----------in--------1000ml
x moles of KMnO4---------------in------------46ml
x = 0,00667 moles of KMnO4

according to the reaction:
2 moles of KMnO4------------------5 moles of H2O2
0,00667 moles of KMnO4----------------x
x = 0,01668 moles of H2O2

0,01668 moles of H2O2---------in-----------50ml
x moles of H2O2--------------------in----------1000ml
x = 0,334 mol/L H2O2

A graduated cylinder has 20 ml (cm3) of water placed in it. An irregularly shaped rock is then dropped in the graduated cylinder and the volume of the rock and water in the cylinder now reads 30 ml (cm3). The mass of the rock dropped into the graduated cylinder is 23 grams. a.) Find the volume of the rock dropped into the graduated cylinder.
b.) Find the density of the rock dropped into the graduated cylinder.

Answers

Answer:

$\boxed {\boxed {\sf v=10 \ mL \ and \ d=2.3 \ g/mL}}$

Explanation:

Answer:

Explanation:

A. Volume

The volume was found using water displacement. Subtract the initial volume from the final volume.

$final \ volume - initial \ volume$

The graduated cylinder had 20 milliliters of water (initial volume).

After the rock was added, the graduated cylinder read 30 milliliters (final volume).

Substitute the values in and subtract.

$30 \ mL- 20 \ mL$

$10 \ mL$

The volume of the rock is 10 milliliters.

B. Density

Density can be found by dividing the mass by the volume.

$d=(m)/(v)$

The mass of the rock is 23 grams. We just found the volume of 10 milliliters.

$m= 23 \ g\nd= 10 \ mL$

Substitute the values in and divide.

$d=(23 \ g)/(10 \ mL)$

$d= 2.3 \ g/mL$

The density of the rock is 2.3 grams per milliliter.

Answer:

Volume = 10 cm3

Density = 2.3g/cm3

Explanation:

volume:

30ml - 20ml = 10ml = 10cm3

density:

density = mass/volume

23/10

2.3g/cm3

Which general trend in period 2 on the Periodic table as the elements are considered in order of increasing atomic number? 1)increasing atomic radius
2.) decreasing electronegativity
3.) increasing 1st ionization energy
4.) decreasing atomic mass

Answers

As the atomic number increase in the 2nd period, the first ionization energy also increases. Therefore, option (3) is correct.

What is the ionization energy?

The ionization energy can be described as the minimum amount of energy that is absorbed by an electron to come out of the influence of the nucleus of a gaseousatom.

In general, the atomic number of an atom increases as we move from left to right in a period on the modern periodic table. While moving from left to right, there is an increase in the effective nuclear charge while the electron enters the same electron shell.

The atomic radius of an atom in the period decreases in the order of increasing atomic number. As the effective nuclear charge is increasing large amount of energy is required to knock out the electron from an atom. Therefore, the first ionization energy also increases as the atomicnumber increase in the 2nd period.

According to the FDA, products labeled gluten-free must contain less than _______ of gluten.a. 5 milligrams
b. 10 grams
c. 20 milligrams
d. 50 grams

Answers

Answer: 20 milligram per kilo gram of food.

Explanation:

FDA: Food and drug Administration

According to FDA, product labelled as gluten free must contain 20 parts per million gluten. This also means that 20 milligram of gluten per kilo gram of food. or we can also say that 20 milligrams of gluten per 35.27 ounce of food.

Hence,the correct answer is option (c).

According to the FDA, products labeled gluten-free must contain less than 20 milligrams of gluten
