Answer:

d. 6

Explanation:

Chemical equation:

I₂ + Cl₂ + H₂O   →    HIO₃ + HCl

Balanced chemical equation:

I₂ + 5Cl₂ + 6H₂O   →   2HIO₃ + 10HCl

Step 1:

I₂ + Cl₂ + H₂O   →    HIO₃ + HCl

Reactant                                         Product

I  =  2                                                I = 1  

Cl = 2                                              Cl = 1

H = 2                                                H = 2

O = 1                                                 O = 2

Step 2:

I₂ + Cl₂ + H₂O   →  2 HIO₃ + HCl

Reactant                                         Product

I  =  2                                                I = 2

Cl = 2                                              Cl = 1

H = 2                                                H = 3

O = 1                                                 O = 6

Step 3:

I₂ + Cl₂ + 6H₂O   →  2 HIO₃ + HCl

Reactant                                         Product

I  =  2                                               I = 2

Cl = 2                                              Cl = 1

H = 12                                              H = 3

O = 6                                                O = 6

Step 4:

I₂ + Cl₂ + 6H₂O   →  2HIO₃ + 10HCl

Reactant                                         Product

I  =  2                                               I = 2

Cl = 2                                              Cl = 10

H = 12                                              H = 12

O = 6                                                O = 6

Step 5:

I₂ + 5Cl₂ + 6H₂O   →  2HIO₃ + 10HCl

Reactant                                         Product

I  =  2                                               I = 2

Cl = 10                                             Cl = 10

H = 12                                              H = 12

O = 6                                                O = 6

How many kJ of heat are released by the reaction of 25.0 g of Na2O2(s) in the following reaction? (M = 78.0 g/mol for Na2O2)
solong [7]

-20.16 KJ of heat are released by the reaction of 25.0 g of Na2O2.

Explanation:

Given:

mass of Na2O2 = 25 grams

atomic mass of Na2O2 = 78 gram/mole

number of mole = \frac{mass}{atomic mass of 1 mole}

                          = \frac{25}{78}

                          =0. 32 moles

The balanced equation for the reaction:

2 Na2O2(s) + 2 H2O(l) → 4 NaOH(aq) + O2(g) ∆Hο = −126 kJ

It can be seen that 126 KJ of energy is released when 2 moles of Na2O2 undergoes reaction.

similarly 0.3 moles of Na2O2 on reaction would give:

\frac{126}{2} = \frac{x}{0.32}

x = \frac{126 x 0.32}{2}

 = -20.16 KJ

Thus, - 20.16 KJ of energy will be released.

What's the balanced equation for cellular respiration?
Alik [6]
<span>Correct answer is:

C_{6}H_{12}O_6+6O_{2}\Rightarrow 6CO_{2}+6H_{2}O+energy

But how to get there?

Let's start with simple explanation of what exactly is cellular respiration. 

Cellular respiration is a multistage biochemical oxidation process of organic substances when prime product is energy (ATP - adenosine triphosphate) and other are released waste products. Cellular respiration takes place even if other metabolic processes are stopped, but cellular respiration may differ in particular organism groups.Some reactions during whole process of cellular respiration are similar in all types of living organisms.

Cellular respiration is prime indication of declining living processes.Only viruses which are on the edge of living organism and chemical particle are not performing cellular respiration.But to the point :P

In cellular respiration all substrates which are in the cell might be organic, but mostly we are using sugar oxidation - glucose in the presence of oxygen. Chemical formula of sugar looks like this:

C_{6}H_{12}O_6

Oxygen is just

O_2

so for now we have just part of the equation:

C_{6}H_{12}O_6+O_{2}\Rightarrow

But what would be on the right hand side?

It's quite simple, remember equation of full combustion? If we want to burn something we need oxygen like in the equation, so the product of this equation would be carbon dioxide, water and of course energy (ATP).Carbon dioxide formula looks like this:

CO_{2}

As a reminder water formula:

H_{2}O

Full formula would look like that:

C_{6}H_{12}O_6+O_{2}\Rightarrow\ CO_{2}+H_{2}O+energy

But still as you see this equation is unbalanced, after balancing it would like that:

C_{6}H_{12}O_6+6O_{2}\Rightarrow 6CO_{2}+6H_{2}O+energy

At the end I would like to explain one more thing. Energy which has been released during this process is part of high-energy connection which might be used to perform chemical reactions in the cell or to move organism for example in muscles. We need to remember that production of ATP is not happening with 100% efficiency and part of this energy is released as heat.</span>

the more particles a substance has at a given temperature the more thermal energy it has true or false
Flauer [41]

Answer:

\huge\boxed{\sf True}

Explanation:

Temperature and thermal energy are in a direct proportion which means that if temperature of a substance increases, its thermal energy also increases and vice versa.
