A cylinder containing 14.71 L of helium gas at a pressure of 169.1 atm is to be used to fill toy balloons to a pressure of 1.086

atm. Each inflated balloon has a volume of 2.414 L. What is the maximum number of balloons that can be inflated? Report your answer to 1 decimal place. (Remember that 14.71 L of helium at 1.086 atm will remain in the exhausted (empty) cylinder)

Answer:

The number of balloons is 948.8.

Explanation:

The number of balloons can be calculated as follows:

N = \frac{V_{f}}{V_{T}}

Where:

V_{f}: is the volume at 1.086 atm

V_{T}: is the balloon volume = 2.414 L  

The volume at 1.086 atm can be found using Boyle's law:

P_{i}V_{i} = P_{f}V_{f}

V_{f} = \frac{P_{i}V_{i}}{P_{f}} = \frac{169.1 atm*14.71 L}{1.086 atm} = 2290.5 L

Now, the number of balloons is:

N = \frac{V_{f}}{V_{T}} = \frac{2290.5 L}{2.414 L} = 948.8

Therefore, the number of balloons is 948.8.

I hope it helps you!

What happens to the speed of motion of the particles of a gas when a certain volume of the gas is heated at constant pressure? E
Vitek1552 [10]
As the gas is heated, the particles will begin to move faster. Likewise if you start to cool a gas, the particles will move slower. Because the gas remains at a constant pressure and volume, the particles cannot spread out so they simply move around the container even faster.

Hope this helps :)

Which is the correct name of a compound that is formed by Si and O?
svp [43]
Naming conventions for 2 non-metals like Si and O are based on their valence electrons,  Si has 4 electrons around it and Oxygen has 6, in order for you to satisfy octet (8 electrons around each element) surrounding each Si and O, you need another O,  To name these 2, just write the name of the first element which has less electrons first then the second element to which you use a prefix "di" since it means there are two oxygen, then put the names together and end the name of the second element with "ide" (remove the last 4 letters).
Silicon + "dI" + ox +"ide"

Based on molecular orbital theory, the bond orders of the H—H bonds in H 2 , H 2 + , and H 2 - are _________, respectively
vodka [1.7K]

Answer:

H2-1

H2+-1/2

H22- zero

Explanation:

Bond order= Bonding electrons-antibonding electrons/2

In H2, there are two bonding electrons and no antibonding electrons. In H2+ there is only one bonding electron and no antibonding electron while in H22- there are two bonding and two antibonding electrons respectively.

This equation represents a:
Leto [7]

Answer : The correct option is, (D) double replacement reaction

Explanation :

Synthesis reaction : A chemical reaction where multiple substances or reactants combine to form a single product.

It is represented as,

X+Y\rightarrow XY

Decomposition reaction : A chemical reaction in which larger reactant decomposes to give two or more than two products.

It is represented as,

AB\rightarrow A+B

Single replacement reaction : A chemical reaction in which the more reactive element replace the less reactive element.

It is represented as,

A+BC\rightarrow AC+B

In this reaction, A is more reactive element and B is less reactive element.

Double replacement reaction : It is a type of chemical reaction where a positive cation and a negative anion of two reactants exchange places to form two new products.

It is represented as,

XY+AB\rightarrow XB+AY

(X and A are the cations, Y and B are the anions)

The given reaction is:

2NaCl(aq)+CuSO_4(aq)\rightarrow Na_2SO_4(aq)_CuCl_2(aq)

This reaction is a double displacement reaction.
