Methane and sulfur react to produce carbon disulfide (CS₂), a liquid often used in the production of cellophane.

2CH₄ + S₈ --> 2CS₂ + 4H₂S

Calculate the moles of H₂S produced when 2.25 mol S₈ is used.

Answers

Answer:

9 moles

Explanation:

The balanced chemical equation provided in this question is as follows:

2CH₄ + S₈ → 2CS₂ + 4H₂S

In accordance to the above balanced equation, 1 mole of sulphur (S8) produces 4 moles of hydrogen sulfide (H2S).

Therefore, if 2.25mol of S8 is used, 2.25 × 4 = 9 mol

9 moles of H2S is produced.

What is created when an acid is mixed with a base?

Answers

Answer:

If you mix equal amounts of a strong acid and a strong base, the two chemicals essentially cancel each other out and produce a salt and water. Mixing equal amounts of a strong acid with a strong base also produces a neutral pH (pH = 7) solution.

- Rachel performed an investigation to study the thermal conductivity of four different materials. She started with four identically shaped rods—each made of a different material. Then, she placed one end of each rod into a pot of boiling water, which was at 100°C.

- After five minutes, Rachel measured the temperatures of the ends of the rods that were sticking up out of the pot to see whether they got hot. Her results are shown below.

Thermal Conductivity Investigation
Material Temperature of End of Rod After 5 Minutes
Material 1 41°C
Material 2 53°C
Material 3 98°C
Material 4 59°C

A 20 g granite boulder absorbs 300.2 Joules of energy from the Sun, resulting in its temperature
changing. Calculate this temperature change

Answers

Answer:

19 °C

Explanation:

Step 1: Given and required data

Mass of granite (m): 20 gHeat absorbed (Q): 300. 2 JSpecific heat capacity of granite (c): 0.790 J/g.°C

Step 2: Calculate the temperature change (ΔT)

We will use the following expression.

Q = c × m × ΔT

ΔT = Q/c × m

ΔT = 300.2 J/(0.790 J/g.°C) × 20 g = 19 °C

How many moles of aspirin (C9H8O4) are contained in 3.13 g of aspirin?

Answers

Answer:

The correct answer is - 0.0173888 moles.

Explanation:

Aspirin, C 9 H 8 O 4 , the atomic mass rounded to the nearest whole number, so: c- 12 h- 1 o - 16

now multiply these number by how many of each there are in the formula:

c - 12 x 9 = 108

h - 1 x 8 = 8

0 - 16 x 4 = 64

add these numbers up 108 + 8 + 64 = 180

aspirin has a molar mass of

180.g mol ^− 1 . This means that one mole of aspirin will have a mass of 180 g .

You're dealing with 3.13 g of aspirin, which will be equivalent to

3.13 g /180g

= 0.0173888 moles aspirin

Complete the dialogues by selecting the appropriate words or expressions and writing them in the corresponding ovals The Soviet structure of power is committed to the perfection of the dictatorship and to maintaining the concept that Russia is in a state of siege, with an enemy that lies just beyond the walls. This mentality has profound implications for Russias international conduct. Moscow assumes that the aims of the capitalist world are antagonistic to the Soviet regime. However, the Kremlin is under no compulsion to accomplish its goal of spreading its influence in a hurry. If it finds unassailable barriers in its path, it accepts them and accommodates itself to them. There is no trace of any feeling in Soviet psychology that that goal must be reached at any given time.In these circumstances it is clear that the main element of any United States policy toward the Soviet Union must be that of patient and vigilant containment of Russian expansive tendencies. Soviet economic development, while it can list certain formidable achievements, has been precariously spotty and uneven. It is difficult to see how the deficiencies of the Soviet economic system can be corrected by a tired and dispirited population working largely under the shadow of fear and compulsion. And as long as they are not overcome, Russia will remain an economically vulnerable and impotent nation, capable of exporting its ideological enthusiasm but unable to export real evidence of material power and prosperity. Indeed, it is the strong belief of this writer that Soviet power bears within it the seeds of its own decay, and that the sprouting of these seeds is well advanced.George F.
