What volume of 0.100 M AgNO3 is
needed to react completely with
45.0 mL of 0.230 M Na2S?
2AgNO3 + Na2S → Ag2S + 2NaNO3
[?] mL AgNO3

Answers

Answer:

448mL AgNO3

Explanation:

M x V

n = 0.230 x .045 = 0.01

2AgNO3 + Na2S --> Ag2S+2NaNO3

1 mol Ag2S --> 2 moles AgNO3

.01 mol Ag2S --> ? moles AgNO3

.01x2/1=.02 moles AgNO3

Moles to L conversion is multiplying by 22.4L so we do .02 x 22.4=0.448L

Then we convert to mL so we multiply by 1000 (1000 x 0.448)

448mL AgNO3

Lithium has an atomic mass of 6.941 amu. Lithium has two isotopes. One isotopes has a mass of 6.015 amu with a relative abundance of 7.49%. What is the mass of the other isotopes?

Answers

Explanation:

List the known and unknown quantities and plan the problem. Change each percent abundance into decimal form by dividing by 100. Multiply this value by the atomic mass of that isotope. Add together for each isotope to get the average atomic mass.

Answer:

The atomic mass of second isotope is 7.016

Explanation:

Given data:

Average Atomic mass of lithium = 6.941 amu

Atomic mass of first isotope = 6.015 amu

Relative abundance of first isotope = 7.49%

Abundance of second isotope = ?

Atomic mass of other isotope = ?

Solution:

Total abundance = 100%

100 - 7.49 = 92.51%

percentage abundance of second isotope = 92.51%

Now we will calculate the mass if second isotope.

Average atomic mass of lithium = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  / 100

6.941 = (6.015×7.49)+(x×92.51) /100

6.941 =  45.05235 + (x92.51) / 100

6.941×100 = 45.05235 + (x92.51)

694.1 - 45.05235   = (x92.51)

649.04765 = x 92.51

x = 485.583 /92.51

x = 7.016

The atomic mass of second isotope is 7.016

Define atomic numbers and mass numbers

Answers

Atomic numbers is the number of a chemical element in the periodic table and the mass number is the total number of protons and neutrons in an atom

Answer:

1). Atoms of each element contain a characteristic number of protons. In fact, the number of protons determines what atom we are looking at (e.g., all atoms with six protons are carbon atoms); the number of protons in an atom is called the atomic number.

2) In contrast, the number of neutrons for a given element can vary. Forms of the same atom that differ only in their number of neutrons are called isotopes.

3) Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

(NO LINKS PLS) From Freezing to Globalizing (The Cold War, and Globalization) What is The Cold War, and Globalization? Why are they so important? How did they shape the world we live in today? In 1945, World War II ended. This meant different things to different areas of the world. In Europe, the war left deep scars that did not heal easily, especially when it came to its economy. In the United States, 1945 was the beginning of an economic boom, as the US was able to take advantage of the markets not covered by Europe, while at the same time increasing production to help with the rebuilding of the continent. Another power that became stronger after the end of the war was the Soviet Union. The years that followed WWII are known as the Cold War, as the United States and the Soviet Union fought for control of other countries. Their opposite ideals of (capitalism vs. communism) led to a Brobdingnagian conflict. Ultimately, the Cold War diminished in importance during the 1980s and 1990s, as the Soviet Union adopted more capitalist measures. Eventually, the Union would break up and collapse resulting in the creation of Russia and several other countries. Leaving The United as the worlds only superpower. The years following the end of the Soviet Union saw a congenital transformation of communication technology, mostly due to the internet. The creation of the internet and the popularity of new technological devices such as (computers, cell phones, etc.) led to a nonpareil phenomenon known as globalization. Globalization allowed us to be in closer contact with the rest of the world, a process that continues to this day. This is how globalization and The Cold War shaped the world.
