A small helium tank measures about two feet high. Yet it can fill over 50 balloons! How can such a small tank contain enough hel

ium to fill so many balloons?
Chemistry

It will only take a small amount of helium when inflating balloons. For example, an 11" balloon only needs 0.015 m3 of helium. So it make sense, why a two feet helium tank can inflate at about 50 balloons. Also, the size tank (2 ft. high) does not define the capacity of helium it contains.

Water molecules are polar, with the Select one:
shusha [124]

Answer:

b. oxygen side being slightly negative and the hydrogen side being slightly positive.

Explanation:

The water molecule is a polar molecule, that is to say that its distribution of electronic density is different throughout the molecule.

In this way, in the water molecule there is a negative partial charge towards the oxygen atom and a positive partial charge towards the hydrogen atom.

This polar characteristic of the water molecule allows ions and other molecules to exhibit water solubility and is widely used in chemical reactions.

Which electrophiles can react with an enol?
dlinn [17]

THE MOLECULE HAS A C=C AND AN -OH GROUP, SO IT IS CALLED AN ENE/OL, I.E., AN ENOL. ENOLS CAN BE FORMED ONLY FROM CARBONYL COMPOUNDS WHICH HAVE ALPHA HYDROGENS. THEY CAN BE FORMED BY ACID OR BASE CATALYSIS, AND ONCE FORMED ARE HIGHLY REACTIVE TOWARD ELECTROPHILES, LIKE BROMINE.

consider this reaction at equilibrium at a total pressure: 2h2o(g) o2(g) 2h2o2(g) suppose the volume of this system is twice its
Daniel [21]

The total pressure when the new equilibrium is stabilized is half of the initial pressure of the system.

The given chemical reaction at a stable equilibrium is,

2H₂O(g)+O₂(g) = 2H₂O₂(g)

According to the ideal gas equation,

PV = nRT

P is pressure,

V is volume,

n is moles

R is gas constant,

T is temperature.

Assuming the temperature is constant.

If the volume of the system is twice the initial volume then the total pressure at the new equilibrium can be found out as,

P₁V₁ = P₂V₂

Where, P₁ and V₁ are initial volume and pressure while P₂ and V₂ are final pressure and volume.

If V₂ = 2V₁,

P₂ = P₁/2

So, the final total pressure will be half of the initial pressure.
