He Sprite and Banana Challenge consists of eating two bananas and then drinking a liter of Sprite. This causes you to projectile vomit and throw up all over the place!

The experiment with eating two bananas and then drinking a Sprite has not shown any chemical reaction by people who have done the experiment. People who have studied this believe that it makes some people vomit simply because it is a lot of food to put in your stomach at one time. Most people do not vomit, rather they tend to feel sick after.... i know this because ive done the challenge xD

The equilibrium constant, Kc, is calculated using molar concentrations. For gaseous reactions another form of the equilibrium co

Anarel [89]

Answer:

Kp = 1.41 x 10⁻⁶

Explanation:

We have the chemical equation:

2 A(g) + 3 B(g)⇌ C(g)

In which A and B are the reactants and C is the product. We calculate first the change in the number of moles of gas (Δn or dn):

dn= (sum moles products - sum moles reactants)

= (moles C - (moles A + moles B))

= (1 - (2+3))

= 1 - 5

= -4

We have also the following data:

Kc = 63.2

T= 81∘C + 273 = 354 K

R = 0.082 L.atm/K.mol (it is a constant)

Thus, we introduce the data in the mathematical expression for the relation between Kp and Kc:

$Kc = (RT)^{dn}$ = (0.082 L.atm/K.mol x 354 K)⁻⁴ = 1.41 x 10⁻⁶

Which statements accurately describe Dmitri Mendeleev’s contributions to the development of the periodic table? Check all that a

Varvara68 [4.7K]

Answer:

Mendeleev produced the first orderly arrangement of known elements.

Mendeleev used patterns to predict undiscovered elements.

Explanation:

Mendeleev produced the first orderly arrangement of known elements and used patterns to predict the undiscovered elements.

Those two statments are true.

For the time being there were some 62 known elements. Before Medeleev some schemes to order part of the elements were proposed, but Medeleev showed the relationship between the atomic mass and the properties of the elements (supports second choice). This arrangement is known as the periodic table.

More importantly, Mendeleev predicted correctly the existance and properties of unknown elements, which is his major contribution: he left blanket spaces which where gradually filled when new elements where discovered (this supports the fourth choice).

The first modern chemistry book was written by Antoine Lavoisier (this discards first option).

Mendeleev ordered the elements by increasing mass number (this discards third choice), which was corrected later by the scientist Henry Moseley, who ordered the elements by increasing atomic number (number of protons).

Isotopes were not known by Mendeleev times, so this discards the last option.

How do we balance chemical equations in order to follow the Law of Conservation of Mass?

Bingel [31]

Answer: Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. ...

Use coefficients of products and reactants to balance the number of atoms of an element on both sides of a chemical equation.
