WILL GIVE BRAINLEST!!!!​

Answer: The activation energy of a particular reaction determines the rate at which it will proceed. The higher the activation energy, the slower the chemical reaction will be. The example of iron rusting illustrates an inherently slow reaction.

b) NR

c) [tex]Hg_{(l)} + Zn(NO_3)_2 {(aq)}=> NR[/tex]

d) Welp, no reaction so i don't know.

7a) [tex]KI + Pb(NO_3)_2[/tex]

b) [tex]PbI_2 + KNO_3[/tex]

c) All are aqeuous except for PbI2 which is solid

d) [tex]2KI _{(aq)}+ Pb(NO_3)_2_{(aq)} => PbI_2_{(s)} + 2KNO_3_{(aq)}[/tex]

Check if that is ok or if my work has any issues :).

Answer:

K I will attempt

Explanation:

a)

[tex]O_2_{(g)}+ 2H_2_{(g)} => 2H_2O_{(l)}\\[/tex]

b)

1 : 2 : 2 (I don't know if this is what the question wants but it is what I would answer)

c)

Hydrogen because it requires 2 moles of H2 to react with 1 mole of O2

d)

24 moles of water. Look at stoichiometric coefficient. 2:2 means 24 moles you get 24 moles

e)

Oxygen. 2 < 5/2. Remember, 1 mole of O2 requires 2 moles of H2. But 5/2 is still greater than 2

f)

First, let's find out how many moles of water we can get. Since O2 is the limiting reactant, and O2:H2O ratio is 1:2, we will get 4 moles of H2O. Then, we can multiply 4 by Avogadro's number which is [tex]6.022*10^{23}[/tex] to get the number of molecules. We get: 2.41 * 10^24 molecules of water.

Answer:

I'ma just take the point thank you very much

A farmer can be more successful in understanding which plant produces and how to grow plants with a higher degree of photosynthesis with less material and time exhaustion, by recognizing what the limiting factor is.

Hope this helps! Please correct me if I'm wrong :)

Answer:

18.01528 grams.

Explanation:

Ther are 0.84 moles of [tex]H_{2}O[/tex] in 15.2 g of pure ice.

The molar mass of [tex]H_{2}O[/tex] is 18g.

To calculate the number of moles of a substance in a given mass of the sample, we divide the given mass by the molar mass of the sample,

Number of moles = given mass / molar mass

It is given that we have 15.2g of pure ice. Then the number of moles of [tex]H_{2}O[/tex] will be:

n = 15.2/18

n = 0.84 moles.

Explanation:

magnesium  +  zinc oxide  --> magnesium oxide  +  zinc

Mg + ZnO --> MgO + Zn

Reactants:

- Magnesium

- Zinc Oxide

Products:

- Magnesium oxide

- Zinc

Type of reaction: Displacement Reaction

The provided word equation depicts a chemical reaction between magnesium and zinc oxide that results in the creation of magnesium oxide and zinc.

Magnesium and zinc oxide are the reactants in the process. These are the substances that alter chemically. The process produces magnesium oxide and zinc. These are the new chemicals produced by the chemical process. This reaction undergoes a chemical transformation, as indicated by the term equation. Magnesium oxide and zinc are formed when magnesium interacts with zinc oxide.

The reaction's stoichiometry is not explicitly stated in the word equation. We cannot establish the exact quantities of the reactants and products involved without further information or factors. The term equation denotes that the reaction obeys the rule of mass conservation. The total mass of reactants must equal the total mass of products.

Answer:

A. write balanced chemical equation (including states), for this process.

Explanation:

Almost all hydrocarbon 'burn' reactions involve oxygen; it's by far the most reactive substance in air.  

Hydrocarbon combustions always involve  

[some hydrocarbon] + oxygen --> carbon dioxide + steam.  

C6H6(l) + O2 (g)--> CO2 (g)+ H2O (g)

Balance carbon, six on each side:  

C6H6(l) + O2 (g)--> 6CO2 (g)+ H2O (g)

Balance hydrogen, six on each side:  

C6H6(l) + O2 (g)--> 6CO2(g) + 3H2O (g)

Now, we have fifteen oxygens on the right and O2 on the left.  

Two ways to deal with that. We can use a fraction:  

C6H6 (l)+ (15/2)O2 (g)--> 6CO2 (g)+ 3H2O (g)

Or, if you prefer to have whole number coefficients, double everything  

to get rid of the fraction:  

2C6H6 (l)+ 15O2 (g)--> 12CO2 (g)+ 6H2O (g)

With the SATP states thrown in...  

C6H6(l) + (15/2)O2(g) --> 6CO2(g) + 3H2O(g)

Answer:

Heat is not something that can be contained since it is not a tangible thing. Heat is a process

Explanation:

The wrong thing in this statement "a mug of hot chocolate contains more heat than a glass of cold water."is: Heat is a process. Heat is not something that can be contained since it is not a tangible thing.

Heat can be defined as a state or quality of being hot or in a high temperature.

Heat can also be said to be a transfer of kinetic energy from one environment to another, from one medium to another, or from one object to another.

In conclusion, Heat is a process. Heat is not something that can be contained since it is not a tangible thing.
