The type of chemical reaction in

H2CO3 → H2O+ CO2 is decomposition reaction

Decomposition reaction is a reaction which involve the breakdown of a single compound into two or more elements or compounds. The reaction above is a decomposition reaction because H2CO3 decomposes to yield CO2 and H2O

<span>We have the reaction: CO2 + H2O (yield arrow)> H2CO3. It means that carbon dioxide + water makes H2CO3 or Carbonic Acid. This reaction is also reversible, so H2CO3 (yield arrow)> CO2 + H2O. This reversible reaction gives a name to reaction: Carbonic anhydrase. It means that it removes the water molecul from Carbonic Acid. Answer: This is a reversible reaction : Carbonic anhydrase.</span>

8. Calculate the number of moles of eachsubstance.a. 5.45 x 1026 particles of methane, CH4

Klio2033 [76]

<em>ANSWER</em>

The number of moles of methane is 905.32 moles

STEP-BY-STEP EXPLANATION:

Given information

The number of particles of methane = 5.45 x 10^26 particles

Let x represents the number of moles of methane

To calculate the number of moles, we will be using the below formula

$\text{Number of particles = number of moles x Avogadro's constant}$

Recall that, the Avogadro's constant is given as

$6.02\cdot10^{23}$ $\begin{gathered} 5.45\cdot10^{26}\text{ = x }\cdot\text{ 6.02 }\cdot10^{23} \\ \text{Divide both sides by 6.02 }\cdot10^{23} \\ x\text{ = }\frac{5.45\cdot10^{26}}{6.02\cdot10^{23}} \\ x\text{ = }\frac{5.45}{6.02}\cdot10^{26\text{ - 23}} \\ x\text{ = 0.9053 }\cdot10^3 \\ x\text{ = 905.32 moles} \end{gathered}$

Therefore, the number of moles of methane is 905.32 moles

How can i toast a marshmallow using convection ?

Elina [12.6K]

Convection is where the heat source heats the air, and the air transfers the heat to object. Some people prefer to heat their marshmallow through convection, this is achieved by holding the marshmallow high above the flames where the heated air is rising, transforing the heat into the marshmallow.
