methane and hydrogen sulfide form when hydrogen reacts with carbon disulfide. identify the excess reactant and calculate how much remains after 36 L o fH2 reacts with 12 L of CS2 all at STP

Answers

Answer 1

Answer: At STP, 1 mol of gas occupies 22.4 L of volume. Using this conversion we the starting amounts of the reactants:
1.6071 mol H2
.5357 mol CS2
The balanced equation is:
4H2 + CS2 -> CH4 + 2H2S
This means that 4 moles of H2 reacts with 1 mole of CS2.
Multiplying this ratio with each of the amounts of the reactants:
required CS2 based on amount of H2 = 0.4018 mol CS2
required H2 based on amount of CS2 = 2.1428 mol H2
Therefore, the excess reactant is CS2. To calculate how much is left, we simply subtract the amount of the reactant CS2 with the required amount based on the amount of H2:
0.5357 mol - 0.4018 mol = 0.1339 mol

Answers

Answer:

Combustion reactions must have oxygen as a reactant. Note that the water that is produced is in the gas rather than the liquid state because of the high temperatures that accompany a combustion reaction.

Pure substances found on the periodic table are called what?

Answers

Answer:

An element is a pure substance that cannot be broken down into different types of substances. ... Examples of elements include carbon, oxygen, hydrogen, gold, silver and iron. Each element is made up of just one type of atom. An atom is the smallest particle of an element that still characterizes the element.

Explanation:

Final answer:

Pure substances found on the periodic table are called elements. They can be further divided into categories like main-group elements, transition metals, and inner transition metals such as alkali metals and chalcogens, based on their properties and compound formation.

Explanation:

Pure substances that are found on the periodic table are referred to as elements.

These elements, which include substances like iron, silver, gold, aluminum, sulfur, oxygen, and copper, cannot be broken down into simpler substances via chemical changes.

The elements on the periodic table can be further subdivided based on their properties. For instance, we have the main-group elements, transition metals, and inner transition metals, each which sit in specific locations on the periodic table. A great example would be the elements in group 1, also referred to as the alkali metals. All alkali metals share similar chemical properties and they form compounds that consist of one atom of the element and one atom of hydrogen.

Another example is the chalcogens, also known as the oxygen group or oxygen family. Essentially, the periodic table serves as a map of all the known elements, each with unique properties that classify them as a certain type of element and determine their positioning on the table.

Which of the following two elements will likely form a covalent bond? N and O K and Cl Li and F Na and Sr

Answers

Covalent bonds are also called molecular bonds. These chemical bondings involves atoms sharing electron pairs. Covalent bonding usually happen between 2 non-metals. Non metals are usually found in the left and right most sides of the periodic table. Hence, the answer will be A. N and O since both elements are non-metals.

Answer: N and O

Explanation:

An ionic bond is formed when a metal completely transfers its valence electron to a non metal.

Covalent bond is formed by sharing of electrons between two non metals.

A. N and O both are non metals and thus form a covalent bond.

B. K is a metal and Cl is a non metal and thus form an ionic bond.

C. Li is a metal and F is a non metal and thus form an ionic bond.

D. Na and Sr both are metals

What happens at a hot spot?

Answers

hot spot develops above the plume. Magma generated by the hot spot rises through the rigid plates of the lithosphere and produces active volcanoes at the Earth's surface. As oceanic volcanoes move away from the hot spot, they cool and subside, producing older islands, atolls, and seamounts. As continental volcanoes move away from the hot spot, they cool, subside, and become extinct.
