How many moles of oxygen atoms are present in 3 moles of sulfur dioxide?

Chemistry

Verdich [7]3 years ago

There are two moles of oxygen in one mole of sulfur dioxide, hence the molecular formula being SO2. Therefore, the number of oxygen moles will be double the number of moles of sulfur dioxide.

3 moles SO2 * (2 moles O)/(1 mole SO2) = 6 moles Oxygen atoms

Answer: 6moles of oxygen

Explanation:

The chemical formula for sulphurdioxide is SO2.

3 moles of sulphurdioxide will be 3SO2.

In sulphurdioxide, there is presence of 2 atoms of oxygen (O2). Therefore to get the total number of moles of oxygen in 3moles of SO2, we will multiply the number of atom of oxygen present (2) with the number of moles of SO2 compound (3).

That will be equivalent to 2×3 = 6moles of oxygen.

What is the difference between evaporation and boiling
Gekata [30.6K]
Answer:

Evaporation is slower, occurs only from the surface of the liquid, does not produce bubbles, and leads to cooling. Boiling is faster, can occur throughout the liquid, produces lots of bubbles, and does not result in cooling.

If 0.507J of heat leads to a 0.007 degree C change in water, what mass is present?
Mamont248 [21]

Answer:

17.3 g

Explanation:

<u>Given the following data;</u>

  • Quantity of heat, Q = 0.507 J
  • Temperature = 0.007°C
  • Specific heat capacity of water = 4.2 J/g°C

Mathematically, Heat capacity is given by the formula;

Q = MCT

Where;

  • Q represents the heat capacity or quantity of heat.
  • M represents the mass of an object.
  • C represents the specific heat capacity of water.
  • T represents the temperature.

Making "M" the subject of formula, we have;

M = \frac {Q}{CT}

Substituting the values into the formula, we have;

M = \frac {0.507}{4.2*0.007}

M = \frac {0.507}{0.0294}

<em>Mass, m = 17.3 grams</em>

Use the equation 2cu+o2=2cuo to find how many miles of copper react to form 3.64 mil cuo
Firlakuza [10]
<h3><u>Answer;</u></h3>

3.64 moles

<h3><u>Explanation;</u></h3>

From the equation;

2Cu + O2 → 2CuO

Mole ratio of Cu : CuO = 2: 2 equivalent to 1: 1

Moles of CuO = 3.64 Moles

Therefore;

moles of Cu will be ;

3.64 × 1 = 3.64 moles

Moles of Cu = <u>3.64 moles </u>

Which of the conservationists discussed earlier in this unit is
Arte-miy333 [17]

The correct answer is A. The conservationist credited with founding the Wilderness Society is Bob Marshall.

Bob Marshall was an American forester, botanist, traveler, climber, writer and social activist who advocated the preservation of unspoiled wildlife.

 

He actively contributed to the development and adoption of environmental regulations prohibiting the construction of roads in vast federal specially protected natural areas. In 1935 he became one of the founders of the public environmental organization The Wilderness Society and its main sponsor.  

Today Bob Marshall is considered one of the main initiators of the wildlife movement in the United States. Several geographic features are named after him, including the Bob Marshall Wilderness Nature Reserve in Montana and the Marshall Mountain on the Adirondack Ridge.
