The question is incomplete. The complete question is :

Hydrogen (H_2) gas and oxygen (O_2) gas react to form water vapor (H_2O). Suppose you have 11.0 mol of H_2 and 13.0 mol of O_2 in a reactor. Calculate the largest amount of H_2O that could be produced. Round your answer to the nearest 0.1 mol .

Solution :

The balanced reaction for reaction is :

$2H_2(g) \ \ \ \ + \ \ \ \  \ O_2(g)\ \ \  \rightarrow \ \ \ \ 2H_2O(g)$

11.0                      13.0

11/2                       13/1     (dividing by the co-efficient)

6.5 mol               13 mol    (minimum is limiting reagent as it is completely consumed during the reaction)

Therefore, H_2 is limiting reagent. It's stoichiometry decides the product formation amount from equation above it is clear that number of moles for H_2O will be produced = number of moles of H_2

                                     = 11.0 mol

What mass of zinc is needed to react with 23.1g of phosphoric acid according to the following equation?
Hunter-Best [27]

23.01 g of zinc (Zn)

Explanation:

We have the following chemical reaction:

3 Zn + 2 H₃PO₄ = 3 H₂ + Zn₃(PO₄)₂

number of moles = mass / molar weight

number of moles of phosphoric acid = 23.1 / 98 = 0.236 moles

Taking in account the chemical reaction, we devise the following reasoning:

if           2 moles of H₃PO₄ are reacting with 3 moles of Zn

then      0.236 moles of H₃PO₄ are reacting with X moles of Zn

X = (0.236 × 3) / 2 = 0.354 moles of Zn

mass = number of moles × molar weight

mass of Zn = 0.354 × 65 = 23.01 g

PLEASE HELP!! I REALLY NEED HELP
Allushta [10]

Answer:

Explanation:

1. find the molar mass (amu) of each element and add them to get the whole molar mass.

2. divide the 1 element molar mass with the whole molar mass

3. multiple by 100 and that gives you the % composition.

<h2><u><em>56-57: NaCl</em></u></h2>

1. Na(22.99amu) + Cl (35.453amu)=58.443

2(Na):   \frac{22.99}{58.443} = .393

2(Cl): \frac{35.453}{58.443}= .607

3(Na): .393 * 100=39.3%

3(Cl): .607 * 100= 60.7%

<h2><u>58-60 </u>K_{2} CO_{3}<u /></h2>

1. K: (39.098)(2)=78.196

_ C: (12.011)(1)= 12.011

_O: (15.99)(3) = 47.997

78.196+12.011+47.997= 138.204

2:K: \frac{78.196}{138.204}= .566 <u>Step </u>3: (.566)(100)= 56.6%

2: C: \frac{12.011}{138.204}= .087 <u>Step 3</u>: (.087)(100)= 8.7%

2: O: \frac{47.997}{138.204}= .347 <u>Step 3</u>: (.347)(100) = 34.7%

<h2>61-62 Fe_{3} O_{4}</h2>

1. Fe (55.845)(3)= 167.535

_ O (15.999)(4) = 63.996

167.535+63.996=231.531

2: Fe: \frac{167.535}{231.531}= .724 Step 3: (.724)(100)= 72.4%

2: O : \frac{63.996}{231.531}= .276 Step 3: (.276)(100) = 27.6%

<h2>63-65 C_{3}H_{5}(OH)_{3}</h2>

1.

C(12.011*3)=36.033

H(1.008*5)=5.04 + (1.008*3)=3.024 so its 8.064

O(15.999*3)=47.997

add them: 92.094

2: C: \frac{36.033}{92.094}= .391 Step 3: (.391)(100) = 39.1%

2: H: \frac{8.064}{92.094}= .088 step 3: (.088)(100) = 8.8%

2: O: \frac{47.997}{92.094} = .521 step 3: (.521)(100) = 52.1%
