b. How many grams of oxygen does it take to produce 90.6 grams of Carbon Dioxide​?​

Answers

Answer:

¹/3 C3H8(g) + ⁵/3 O2(g)

Explanation:

The coefficient before every molecule is representative of the number of moles. We can represent it in ration form so as to calculate the question;

C₃H₈(g) + 5 O₂(g) → 3 CO₂(g) + 4 H₂O(l) means;

For every 1 mole of C₃H₈(g) and 5 moles of  O₂(g) produces  3 moles of  CO₂(g) and 4 moles of H₂O(l).

Therefore to produce 1.00 mole of CO₂(g);

We represent it in ratio;

We can write:

5/4 = 3,8/x

Solving for x:

x = 3,04 mols of H2O

Calculating the H2O mass:

M H2O = 18 g/mol

n = m/M

Solving for m:

m = 54,72 g of water

****************************

Using the same, but with molar mass:

M CO2 = 44 g/mol => 3 x 44 = 132 g

M O2 = 32 g/mol => 5 x 32 = 160 g

160/132 = x/90,6

solving for x:

x = 109,82 g if CO2

how many molecules are in 500 moles of Cl2?​

Answers

Answer:

3 x 10^26

Explanation:

You take the number of moles (500) and multiply it by Avogadro's number (6.022 x 10^23) to get the answer.

The number of molecules in one mole of Cl₂ gas is 6.022× 10²³ . Then 500 moles of Cl₂ is 3.01 × 10²⁶.  

What is one mole?

Any substance containing 6.022× 10²³ number of atms is called one mole of the substance. This number is called the Avogadro number. Thus, one mole of  every elements contains Avogadro number of atoms.

Similarly,  one mole of any compounds contains Avogadro number of molecules. One mole of Cl₂ contains 6.022× 10²³ Cl₂ molecules. Thus, the number of molecules in 500 moles of chlorine gas is calculated as follows:

Number of molecules of chlorine gas =  500 ×  6.022× 10²³ = 3.01 × 10²⁶.

Therefore, there will be 3.01 × 10²⁶ number of molecules in 500 moles of chlorine gas.

What is the formula for the ionic compound formed between sodium and oxygen?

Answers

Answer:

Na2O (the 2 is small the o is not a 0 but and OOh)

Explanation:

Hey there, The formula for the compound formed between sodium and oxygen will be Na2O

Though since sodium is a metal and oxygen is a nonmetal, Na2O is expected to be ionic.

What is an ionic compound?

An ionic compound is a chemical compound made up of ions held together by electrostatic forces known as ionic bonding.

To determine an ionic compound's formula, first identify the cation and record its symbol and charge.

After that, identify the anion and record its symbol and charge. Finally, mix the two ions together to make an electrically neutral compound.

After two or more atoms lose or gain electrons to form an ion, an ionic bond can form.

Ionic bonds form when metals lose electrons and nonmetals gain electrons. Ions with opposite charges attract each other, forming an ionic bond.

The symbol for sodium is Na+, and the symbol for oxygen is O2. The resulting compound here in the given condition is Na2O.

Thus, this is the formula for the ionic compound formed between sodium and oxygen.

A photon has an energy of 2.78 x 1032 J. What is its wavelength?

Answers

Answer:

7.14 × 10^(-58) m

Explanation:

We are given;

Energy; E = 2.78 x 10^(32) J

Formula to find this energy is;

E = hc/λ

Where;

E is energy

h is Planck's constant with a constant value of 6.62 × 10^(-34) J/s

c is speed of light with a constant value of 3 × 10^(8) m/s

λ is wavelength

Making λ the subject, we have;

λ = hc/E

λ = (6.62 × 10^(-34) × 3 × 10^(8))/(2.78 x 10^(32))

λ = 7.14 × 10^(-58) m

Can I please get help with this question ‍♂️?

Answers

Answer:

1.50 moles of POH or Potassium Hydroxide.

Explanation:

First of all, find the substance formula

The substance formula of Potassium Hydroxide is

KOH

Second of all, if you want to convert from grams to moles, you use molar mass of KOH

Third of all, find the molar mass of KOH.

K = 39.1 amu

O = 16.0 amu

H= 1.0 amu

Potassium has 1 atom, oxygen has 1 atom, and hydrogen has 1 atom.

So do this:

39.1(1) + 16.0(1) + 1.0(1) = 56.1

The molar mass of KOH is 56.1 g/mol.

Fourth of all, use dimensional analysis to show your work.

84.20 grams of KOH * 1 mol/56.1 g/mol

The moles will cancel out.

84.20 divided by 56.1 = 1.500892166

But I have to round my answer to two digits after the decimal points instead of using sig figs.

So I round to the hundredths place

1.500892166 = 1.50

So the final answer is 1.50 moles(don't forget the units) of POH.

Hope it helped!

Calculate the mass of beryllium (Be) needed to completely react with 18.9 g nitrogen gas (N2) to produce Bez N2, which is the only product of the reaction.
A. 6.19
B. 12.29
C. 18.29
D. 36.69

Answers

Answer:

C = 18.29 g  

Explanation:

Given data:

Mass of beryllium needed = ?

Mass of nitrogen = 18.9 g

Solution:

Chemical equation:

3Be + N₂    →    Be₃N₂

now we will calculate the number of moles of nitrogen:

Number of moles = mass/molar mass

Number of moles = 18.9 g/ 28 g/mol

Number of moles = 0.675 mol

Now we will compare the moles of nitrogen and Be from balance chemical equation.

                     N₂        :       Be        

                       1          :       3

                  0.675       :      3/1×0.675 = 2.03 mol

Number of moles of Be needed are 2.03 mol.

Mass of Beryllium:

Mass = number of moles × molar mass

Mass = 2.03 mol ×   9.01 g/mol

Mass = 18.29 g

b. single replacement
C. combustion
d. double replacement
e. decomposition

Answers

Answer:

Option B. Single replacement reaction

Explanation:

To know which option is correct, it is important that we know the definition of each option. The definition of each option is given below:

1. Synthesis reaction is a reaction in which two different elements or compound combine together to produce a new compound different from the two starting elements or compound. An example is illustrated below:

C + D —> E

2. Single replacement reaction is a reaction in which an element replaces or displaces another element in a compound. An example is illustrated below:

D + BC —> B + CD

3. Combustion reaction is a reaction in a substance react with oxygen to generate carbon dioxide (CO₂) and water (H₂O). An example can be seen when organic compound react with oxygen to produce carbon dioxide (CO₂) and water (H₂O). This is illustrated below:

CₓHᵧ + (x + y/4) O₂ —> xCO₂ + (y/2) H₂O

4. Double replacement reaction is a reaction in which the ions of the two reacting compound replaces one another to form new products. This is illustrated below:

X⁺Y¯ + U⁺V¯ —> X⁺V¯ + U⁺Y¯

5. Decomposition reaction is a reaction in which a large compound breaks down into two or more elements or compound. An example is illustrated below:

GH —> G + H

Now, observing the equation given in the question above:

Sn + 2HCl —> SnCl₂ + H₂

We can see that Sn replaces H in HCl to produce SnCl₂.

Therefore, the reaction is a single replacement reaction.

1 mole   1 mole           1 mole          1 mole

6.93  g of hydrochloric acid = 6.93 / 36.5 = .189 mole of HCl

2.4 g of NaOH = 2.4 / 40 =  .06 mole of NaOH

NaOH is in short supply so it is the limiting reagent .

1  mole of NaOH reacts with 1 mole of HCl to give 1 mole of Water
