A balloon has a volume of 18.0-L at a pressure of 87.6 kPa. What will be the new volume when the pressure is 48.2 kPa?

Answer:

32.71 L

Explanation:

We can solve this question using Boyle's law of ideal gas. The law states that the volume and pressure are inversely proportional when the temperature is constant. At first, the volume is 18L (V1) and the pressure is 87.6 kPa(P1). Then the pressure changed into 48.2 kPa(P2). We are asked to find the volume(V2).

The calculation will be:

P1 * V1= P2 * V2

87.6 kPa  *18L = 48.2 kPa * V2

V2=  87.6 kPa  *18L / 48.2 kPa

V2=32.71 L

which one of the following is not an example of a combination reaction a. 2H2O(I)---> 2H2(g)+O2(g) b. 2K+CI2--->2KCI c. 2H
Alexxandr [17]
The answer would be A.

Combination reaction, otherwise known as synthesis reaction, occurs when two or more substances react and form a single, more complex substance.

A combination reaction looks like this in an equation:

                                     <em> A + B         </em><em>→       </em><em>AB</em>
                                   reactants              product

So from two reactants they become one product. 
Let's take a look at choice A.

                                   2H₂O(l)       →      2H₂(g) + O₂(g)
                                  reactant                     product(s)

Notice that from one substance, it broke down into two substances. So this is not a combination reaction. This is what you call a <em>decomposition reaction. </em>

We can calculate the force that the atmospheric pressure produces on a surface. Consider a living room that has a 4.0m×5.0m floo
qaws [65]

Answer:

Force, F=2.02\times 10^6\ N

Explanation:

It is given that,

Length of the room, l = 4 m

breadth of the room, b = 5 m

Height of the room, h = 3 m

Atmospheric pressure, P=1\ atm=101325\ Pa

We know that the force acting per unit area is called pressure exerted. Its formula is given by :

P=\dfrac{F}{A}

F=P\times l\times b

F=101325\times 4\times 5

F=2.02\times 10^6\ N

So, the total force on the floor due to the air above the surface is 2.02\times 10^6\ N. Hence, this is the required solution.

What is the two different atoms in a ring
snow_tiger [21]

Answer:

If two or more atoms of the same element combine, they produce a molecule, for example, H2, O2, O3, etc.

If, however, two (or more) atoms of different elements combine, they produce a compound, for example, NO, CO, FeS, NaCl, etc. The compound may be called a molecule if it is made of independent units, such as NO and CO. However, FeS and NaCl are not molecules because there is no independent unit made of one atom of Fe and a single atom of sulfur or a single unit of Na and Cl. These compound are made of a network of large number of ions of Fe^+2 and S^-2 and Na^+1 and Cl^-1 as a ionic crystallines. If you could isolate a single FeS or NaCl (for example in the gaseous state) you could call them also molecules.
