Write sulfur dioxide reactions
scZoUnD [109]

Answer:

Sulfur dioxide is a covalent bond because  we have two non-metals (Sulfur and Oxygen).

S + O_{2} \to SO_{2} (<em>Sulfur dioxide formula)</em>

It's called Sulfur dioxide but it can be called Sulfurous anhydride and Sulfur (lV) oxide.

Sulfur dioxide can have different reactions:

  • In the presence of oxygen oxidation of sulfur dioxide to sulfur trioxide occurs and the formula is:

SO_{2}+\frac{1}{2} O_{2}= SO3

The equal is because  it's a reversible equation. This reaction is spontaneous.

  • The sulfur trioxide reacting with water produces sulfuric acid. The formula is:

3 SO_{2} + O_{3} \to 3 SO_{3}\\SO_{3} + H_{2}O \to H_{2}SO_{4}

  • Also the sulfur dioxide reacting with  sodium hydroxide produces sodium sulfite and the formula is:

SO_{2} + 2 NaOH \to Na_{2}SO_{3} + H_{2}O

  • And finally we have the reduction of sulfur dioxide (it can be in presence of  hydrogen sulfide) getting elemental sulfur and water. The formula is:

SO_{2} + 2 H_{2}S \to 3 S + 2 H_{2}O

Electricity is the flow of electrons. The following questions relate to how electricity is quantified.1. Electrons are charged p
kakasveta [241]

Answer:

The correct option are:

1.  (b) current

2. (c) potential

3.  (b) coulombs (C)

4.  (a) amperes (A)

5.  (d) volts (V)

Explanation:

Electric charge is a property of a particle, like electron and proton. The subatomic particles, electrons and protons are negatively and positively charged particles, respectively.

The electric charge of a particle can be measured in <em>coulomb, denoted by C</em>.

Current or electric current is defined as the <em><u>net flow of the electric charges through a given region, per unit time.</u></em> Electric current can be measured in <em>ampere, denoted by A.</em>

<em>Potential or Electric potential</em> is described as the work done to displace the electric charges from one point to another. <em><u>Potential is the driving force for the movement of charges</u></em> and can be calculated in <em>volt, denoted by V.</em>

How many grams of water are produced from the reaction of 40.3 g of oxygen according to this equation? 2h2(g) + o2(g) → 2h2o(g)?
Vikki [24]
The balanced equation for the above reaction is as follows;
2H₂ + O₂ --> 2H₂O
stoichiometry of  O₂ to H₂O is 1:2
number of O₂ moles reacted - 40.3 g / 32 g/mol = 1.26 mol
according to molar ratio 
number of water moles produced = 2 x number of O₂ moles reacted 
number of water moles formed - 1.26 x 2 = 2.52 mol
mass of water produced = 2.52 mol x 18 g/mol = 45.4 g
45.4 g of water produced
