Answer:
44.9g
Explanation:
You have to convert grams of CH4 to moles, use the mole-to-mole ratio of CH4 to water, and convert back to grams.
(20.0g CH4)(1 mol CH4/16.04g)(2 mol H2O/1 mol CH4)(18.01 g H2O/ 1 mol) = 44.9127 g

A balloon has a volume of 31.8 L at a temperature of 46 degrees C. What is the new temperature
of the balloon in degrees C if the volume is changed to 49.2 liters?
Round answers to 0.1 decimals
Answers
Answer:
The new volume will be
0.7 L
Explanation:
This is an illustration of Charles' law, some of the time called the temperature-volume law. It expresses that the volume of a gas is straightforwardly corresponding to the Kelvin temperature, while pressing factor and sum are held steady. The condition is V 1 T 1 = V 2 T 2 , where V is volume and T is temperature in Kelvins. Known V 1 = 0.5 L T 1 = 20 ∘ C + 273.15 = 293 K T 2 = 150 ∘ C + 273.15 = 423 K Obscure V 2 Arrangement Revise the condition to confine V 2 . Substitute the known qualities into the condition and address. V 2 = V 1 T 2 T 1 V 2 = ( 0.5 L × 423 K ) 293 K = 0.7 L adjusted to one huge figure

How many molecules are in 6.20 moles of CaCO3?
Answers
1 mole is equal to 1 moles CaCO3, or 100.0869 grams.
What is mole?A mole is just a measuring scale. In reality, it's one of the International System of Units' seven foundation units (SI). When already-existing units are insufficient, new ones are created.
The mole is a SI unit that is used to quantify any quantity of a substance. The word "mole" is shortened to "mol".
A mole consists of precisely 6.022140761023 particles. The "particles" could be anything, from tiny things like electrons or atoms to enormous things like stars or elephants.
Therefore, 1 mole is equal to 1 moles CaCO3, or 100.0869 grams.

S8 +O2 = SO8
Given 80 mols of product, find the amount of each reactant in mols.
Answers
Answer:
10 moles of S₈
320 moles O₂
Explanation:
S₈ +O₂ → SO₈The balanced equation is:
S₈ + 32O₂ → 8SO₈Now we can convert moles of SO₈ (the product) into moles of each reactant, using the stoichiometric coefficients of the balanced reaction:
80 mol SO₈ * [tex]\frac{1molS_8}{8molSO_8}[/tex] = 10 mol S₈80 mol SO₈ * [tex]\frac{32molO_2}{8molSO_8}[/tex] = 320 mol O₂In order for 80 moles of SO₈ to be produced, 10 moles of S₈ need to react with 320 moles of O₂.

How many grams of NaOH are produced from 2.1g of Na2O?
Na2O + H20 --> 2NaOH
Answers
Answer:
2.72g
Explanation:
The balanced equation of this reaction is given as follows:
Na2O + H20 --> 2NaOH
Based on this balanced equation, 1 mole of Na2O will produce 2 moles of NaOH.
First, we need to convert mass of Na2O into moles by using the formula;
mole = mass/molar mass
Molar mass of Na2O = 23(2) + 16
= 46 + 16
= 62g/mol
mole = 2.1g/62g/mol
mole of Na2O = 0.034mol
Hence, if 1 mole of Na2O will produce 2 moles of NaOH.
Then, 0.034mol of Na2O will produce (0.034 × 2) = 0.068mol of NaOH.
To convert mole of NaOH to mass, we use;
mole = mass/molar mass
Molar mass of NaOH = 23 + 16 + 1 = 40g/mol
0.068 = mass/40
mass of NaOH produced = 2.72g.

A neutralization reaction occurs between sodium hydroxide and sulfurous acid. Complete the equation below for the neutralization reaction that ocurs during the titration
Answers
Answer:
2NaOH + H₂SO₃ → 2H₂O + Na₂SO₃
Explanation:
When a base as sodium hydroxide (NaOH) reacts with an acid as sulfurous acid (H₂SO₃), the H⁺ of the acid will produce with the OH⁻ of the base H₂O. Te complementary ions will produce the respective salt (Na₂SO₃):
NaOH + H₂SO₃ → H₂O + Na₂SO₃
To balance the sodiums:
2NaOH + H₂SO₃ → H₂O + Na₂SO₃
And the hydrogens:
2NaOH + H₂SO₃ → 2H₂O + Na₂SO₃And this is the complete reaction for this neutralization reaction.

Calculate the work for the expansion of CO2 from 1.0 to 6.5 litres against pressure of 1.0 atm at constant temperature
Answers
Answer:
557.3J is the work of expansion of the CO2 gas
Explanation:
The work of expansion of a gas under constant temperature and pressure (Isobaric pressure) is:
W = P*ΔV
Where W is work
P is pressure = 1.0atm
ΔV = Final volume - Initial Volume = 6.5L - 1.0L = 5.5L
Replacing:
W = 1.0atm*5.5L
W = 5.5atmL
In Joules (1atmL = 101.325J):
5.5atmL * (101.325J / 1atmL) =
557.3J is the work of expansion of the CO2 gas
