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 1

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.

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

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

- 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.

Material 1 41°C
Material 2 53°C
Material 3 98°C
Material 4 59°C
