WILL GIVE BRAINIEST is C6H1005 + O2 → CO2 + H2O balanced?

Answer:

320pka

Explanation:

This is a complete question;

If the temperature of a gas increased from 100 K to 200 K and the volume of a gas decreased from 20 L to 10 L, what is the new pressure if the original pressure was 80kPa?

EXPLANATION;

Gas laws can be regarded as aws which relate the pressure, volume, as well as temperature of a gas. It can be expressed as

P1V1/T1 = P2V2/T2

Where

V1= initial volume= 20L

V2 = final volume= 10L

T1 = initial temperature= 100K

T2 = final temperature= 200K

P2=final pressure=

P1= initial pressure= 80pka

Making P2 subject of the formula from the eqn, we have

P2= (P1*V1*T2=)/(T1*V2)

If we substitute the values we have

P2= (80 × 20×200)/(100×10)

P2= 320pka

Hence, the new pressure is 320pka

Answer:

2NaI + F₂    →     2NaF + I₂

Explanation:

Chemical equation:

NaI + F₂    →     NaF + I₂

Balanced chemical equation:

2NaI + F₂    →     2NaF + I₂

The given reaction is single replacement reaction.

Step 1:

NaI + F₂    →     NaF + I₂

left hand side                    Right hand side

Na = 1                            Na = 1

I = I                                 I  = 2

F = 2                               F = 1

Step 2:

2NaI + F₂    →     NaF + I₂

left hand side                    Right hand side

Na = 2                                Na = 1

I = 2                                   I  = 2

F = 2                                  F = 1

Step 3:

2NaI + F₂    →     2NaF + I₂

left hand side                    Right hand side

Na = 2                                Na = 2

I = 2                                    I  = 2

F = 2                                   F = 2

Explanation:

Among the halogens given in this problem, iodine has the lowest attraction for electrons.

This property is known as electronegativity.

Electronegativity is expressed as the relative tendency with which the atoms of the element attracts valence electrons in a chemical bond.

Answer:

Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.

Answer:

18.01528 grams.

Explanation:

Ther are 0.84 moles of [tex]H_{2}O[/tex] in 15.2 g of pure ice.

The molar mass of [tex]H_{2}O[/tex] is 18g.

To calculate the number of moles of a substance in a given mass of the sample, we divide the given mass by the molar mass of the sample,

Number of moles = given mass / molar mass

It is given that we have 15.2g of pure ice. Then the number of moles of [tex]H_{2}O[/tex] will be:

n = 15.2/18

n = 0.84 moles.

Answer:  lone pair of electrons

Explanation: A bonding electron domain is a pair of electrons shared between two atoms and a nonbonding is a lone pair of electrons

The difference between the bonding electron domain and a nonbonding electron domain should be explained below.

A bonding electron domain refers to the region that lies between the two bonded atoms that comprise one or more pairs where the electrons should be bonded.

While on the other hand, the non-bonded electron contains on the single-atom also comprise of one pair of lone pair.

In this way, it should be differentiated.

Answer:

we need to know it's

mass and velocity

Explanation:

then use the formula of kinetic energy

Answer:

Mass and velocity (or motion).

Explanation:

KE=(1/2)mv^2.

The kinetic energy of an object is the amount of work (expended energy) that's required to move (or more accurately, to accelerate) the object to a specific velocity.  So, if you know the mass of the object, and you know it's current velocity, you can determine it's kinetic energy with the formula above.

Answer:

Gold is a relatively dense metal because its atoms have more

protons than atoms of many other metals.

Explanation:

Answer:

The relative velocity is the velocity of an object or observer B in the rest frame of another object or observer A.

Answer:

Relative motion is defined as the calculation of the motion of an object with regard to some other moving or static object. Thus, the motion is not calculated with reference to the earth, but is the velocity of the object in reference to the other moving object as if it were in a static state.

Answer:

6.624× 10²³ molecules      

Explanation:

Given data:

Mass of KOH = 60 g

Number of molecules = ?

Solution:

First of all we will calculate the number of moles.

Number of moles = mass/molar mass

Number of moles = 60 g/ 56.1 g/mol

Number of moles = 1.1 mol

Now number of molecules are determine by using Avogadro number.  

1 mole = 6.022 × 10²³ molecules

1.1 mol × 6.022 × 10²³ molecules / 1mol

6.624× 10²³ molecules        

Avogadro number:

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

Answer:

Mass of CO₂ produced = 299.64 g  

Explanation:

Given data:

Mass of CO₂ produced = ?

Mass of propane (C₃H₈) = 100.0 g

Solution:

Chemical equation:

C₃H₈ + 5O₂     →        3CO₂ + 4H₂O

Number of moles of propane:

Number of moles = mass/molar mass

Number of moles = 100.0 g/  44.1 g/mol

Number of moles = 2.27 mol

Now we will compare the moles of propane and carbon dioxide.

                 C₃H₈          :          CO₂

                    1              :            3

                  2.27          :           3/1×2.27  = 6.81 mol

Mass of CO₂:

Mass = number of moles × molar mass

Mass = 6.81 mol × 44 g/mol

Mass = 299.64 g
