If 50.0 g of oxygen and 50.0 g of hydrogen react to produce water.

Chemistry

Elan Coil [88]2 years ago
6 0

m(O2)=50g

m(H2)=50g

m(H2O)-?

n2(H2)-?

2H2 + O2 = 2H2O

n(O2)= m (O2)/M(O2) =50g / 32 g/mol= 1,56 mol.

n(H2)= m (H2)/M(H2) =50g / 2 g/mol= 25 mol.

Since oxygen gas is the limiting reactant,

n(O2)< 2 n(H2) from reaction.

n(H2O)= 2n(O2)= 2n (H2 reac.)=2*1,56 mol=3,12mol.

m(H2O)=n(H2O)*M(H2O)= 3,12mol* 18 g/mol.

n2(H2)= n(H2) - n (H2 reac.)=25mol - 3,12mol=21,88mol.

Lakes can disappear due to?
stich3 [128]

Answer:

Lakes can vanish due to natural processes and human activity. Bacteria break down lake species' bodies and release nutrients into the water when they die. Eutrophication is the accumulation of nutrients in a lake over time. Lakes and rivers all throughout the world have dried up as a result of rising water demand and a warmer environment. Overpumping of aquifers and excessive diversion of water from rivers.

how much sodium chloride must be added to 100 mL of water so that its concentration is 20 parts per million assume that the dens
OlgaM077 [116]
Answer: 2mg

Part per million is unit that equal to mg/kg of water or simply 10^{-6} . In this case, you asked how much NaCl needed and know the volume of water(100mL), concentration(20ppm or 20 mg/kg) and water density.
Then, the equation would be

concentration = NaCl weight/ water weight
20 x 10^{-6} mg= NaCl weight/ (100ml x 1g/ml)
NaCl weight= 20x 10^{-6} mg/kg x 100g 
NaCl weight= 2000 x 10^{-6} g
NaCl weight= 2x 10^{-3} g = 2mg

a culinary student fills a 40ml container with 37.2 grams of vegetable oil.What is the density of the oil
Lynna [10]

Answer:

<h2>0.93 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 37.2 g

volume = 40 mL

We have

density =  \frac{37.2}{40}  \\  = 0.93

We have the final answer as

<h3>0.93 g/mL</h3>

Hope this helps you

7. A cyclist starting from rest accelerates at a rate of 6 m/s until she reaches 30 m/s. How long
Hunter-Best [27]

Answer:

Explanation:

The given values are:

a= 6m/s²

u= 0 m/s

v = 30 m/s

t= ?

The formula is :

a=\frac{v-u}{t}

thus,

t=\frac{v-u}{a}\\t=\frac{30-0}{6}\\t= 5 seconds
