mole equations please help me :(

Answers

Answer:

A. 0.48mol O2

Explanation:

The balanced equation is given as follows:

2CH3OH + 3O2 → 2CO2 + 4H2O

This shows that 2moles of CH3OH is required to react with 3 moles of O2

If 0.32 moles of CH3OH are reacted, then;

0.32 × 3/2 moles of O2 is required

= 0.96/2

= 0.48mol of O2

Equilibrium constant Kp for the reaction P4(s) + 6Cl2(g) 4PCl3(l) Kp = 1/ P6Cl2 Kp = P4Cl3/ P6P4 Kp = P4Cl3/ (P6P4) (P6Cl2) Kp = 1/ (P6P4) (P6Cl2)

Answers

Answer: [tex]K_p=\frac{1}{[p_{Cl_2}]^6}[/tex]

Explanation:

Equilibrium constant is defined as the ratio of pressure of products to the pressuure of reactants each raised to the power their stoichiometric ratios. It is expressed as [tex]K_p[/tex]  

For the given chemical reaction:

[tex]P_4(s)+6Cl_2(g)\rightarrow 4PCl_3(l)[/tex]

The expression for [tex]K_p[/tex] in terms of gaseous is written as:

[tex]K_p=\frac{1}{[p_{Cl_2}]^6}[/tex]

I am wondering how to find out the blood type of my grandson...my daughter is A+..father is in question...she is stressed to the max on the father of this baby boy.

Answers

Answer:

A person can identify their blood type at home using a rapid blood typing kit. Using the kit requires a person to pierce a finger with a needle. The kit comes with a card that contains chemicals known as reagents. These test for the presence of the antibodies and Rh factor.

Explanation:

Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.

If 0.525 moles of O2 are produced, how many moles of KClO3 are decomposed?

Answers

Answer:

B. 0.35mol KClO3

Explanation:

The balanced equation in this question is given as follows:

2KClO3 → 2KCl + 3O2

Based on the chemical reaction;

2 moles of KClO3 decomposes into 3 moles of O2

If 0.525 moles of O2 are produced, then:

= 0.525 × 2/3

= 1.05/3

= 0.35mol of KClO3 is decomposed.

_ Na+Cl 2 -> _NaCl
reactant side number of atoms?
Na = ?
Cl = ?
Product side number of atoms?
Na = ?
Cl = ?
what is the final equation?
_ Na+Cl 2 -> _NaCl

Answers

Answer:

2Na+Cl2 -> 2NaCl

Explanation:

1Na+1Cl 2 -> 1NaCl (i'm assuming they want you to balance it so ill start with 1)

Na = 1

Cl = 2 (it is 2 because it is Cl2, meaning that there are 2; but remember that you cannot change this number only coefficients)

Na = 1

Cl = 1

We need to have 2 Cl on the product side

1Na+1Cl 2 -> 2NaCl

Now we need 2 Na on the reactants side

The final equation is

2Na+Cl2 -> 2NaCl

Now it is balanced

Na = 2

Cl = 2

--

Na = 2

Cl = 2

Which of the following is not an example for electroplating? A Tin cans for storing food
B Chromium used on bath taps to get shiny appearance
C Copper used for making electrical wires
D To protect iron objects used in machineries, from corrosion
If you answer you will get brainiest
Please answer and thank

Answers

Answer:

C. Copper used for making electrical wires

Explanation:

When a coating of a particular metal is applied on another metal, the process is termed as electroplating. The process is carried by the process of electro-deposition. This process is carried on in order to enhance the quality of the objects manufactured. The coating helps in resistance and provides an attractive appearance to the object.  

Option C. is not an example of electrocoating because on the copper wires no other metal coating is done. In all the other three options, coating has been done on the object.
