What mass of h2o is formed when h2 reacts with 384 grams of o2?

Chemistry

Tasya [4]3 years ago

Answer is: mass of water is 432 grams.
Chemical reaction: 2H₂ + O₂ → 2H₂O.
m(O₂) = 384 g.
M(O₂) = 2 · 16 g/mol = 32 g/mol, molar mass.
n(O₂) = m(O₂) ÷ M(O₂).
n(O₂) = 384 g ÷ 32 g/mol.
n(O₂) = 12 mol, amount of substance.
From chemical reaction: n(O₂) : n(H₂O) = 1 : 2.
n(H₂O) = 12 mol · 2 = 24 mol.
m(H₂O) = n(H₂O) · M(H₂O).
m(H₂O) = 24 mol · 18 g/mol.
m(H₂O) = 432 g.

Water is made of polar molecules, and oil is made of nonpolar molecules. Based on your observations, which molecules attract eac
victus00 [196]

Based on observation of polar and non-polar molecules, polar molecules would attract each other more strongly.

<h3>What are polar and non-polar molecules?</h3>

Polar molecules are those molecules that can ionize or dissociate into their respective positive and negative ions when in an aqueous solution.

Nonpolar molecules, on the other hand, are not ionic i.e. not dissociating into ions when dissolved in water.

Polar molecules like water (H2O) contains an uneven distribution of cations (+) and anions (-), hence, would be more attracted to one another than nonpolar molecules that have an even distribution of ions.

Answer:

B. Extreme heat and pressure.....

Explanation:

This is how sedimentary rocks are actually made. I had learned recently in my class about these rocks, and my teacher told that these are made by heat and pressure. And these are the types of rocks that you'll find in canyons for example Grand Canyon.

You know that when something gets pressurized then it changes shape, same for rocks, if they're having lots of pressure on them, then they will also basically turn into newer rocks and also change shape. They also change looks because sedimentary rocks don't look like any other type of rock.

Also, heat can also be found in the crust of the earth since there is the Mantle under the crust which is filled up of MAGMA! (supa hot magma!! woohoo!) And also, because all of the dirt and stuff underground is packed together, the friction can also create heat. As you know, heat makes things expand, you might have done this before.... when you learned about hot and cold gas, you might have also learned that hot gases are more larger, and require more volume than cold gas. That means that the size of the object changes, that too, it's not just for gas, it's for everything, <em>including rocks!</em>.

Hence, your answer is B. Extreme heat and pressure from inside the earths surface......

:D

Consider molecular, complete ionic, and net ionic equations.
8090 [49]

Explanation:

(a) The molecular equations shows the equation in which all the species of the reactants and the products are in molecules and the net charge is zero.

The complete ionic equations shows the equation in which all the species of the reactants and the products are in dissociated form and are represented as ions.

The net ionic equations shows the equation in which all the species of the reactants and the products are in dissociated form and do not show the spectator ions which are same in the reactants and the products.

(b) If there is no spectator ions in the reaction, then the complete and the net ionic equations would be identical.

7. I have 2.50 x 1023 atoms of titanium. How many moles of titanium dol<br> have?
algol13

Answer:

0.42mole

Explanation:

Given parameters:

Number of atoms of titanium  = 2.5 x 10²³atoms

Unknown:

Number of moles  = ?

Solution:

To solve this problem, we must understand that a mole of any substance contains the Avogadro's number of particles.

              6.02 x 10²³ atoms makes up 1 mole of an atom

              2.5 x 10²³ atoms will contain \frac{2.5 x 10^{23} }{6.02 x 10^{23} }   = 0.42mole
