In the equation CH4 + 2O2 --> 2H2O + CO2 What is the mass of CO2 produced when 35g of O2 reacts?
Answer:
24.06 g of CO₂
Explanation:
The balanced equation for the reaction is given below:
CH₄ + 2O₂ —> 2H₂O + CO₂
Next, we shall determine the mass of O₂ that reacted and the mass of CO₂ produced from the balanced equation. This can be obtained as follow:
Molar mass of O₂ = 2 × 16 = 32 g/mol
Mass of O₂ from the balanced equation = 2 × 32 = 64 g
Molar mass of CO₂ = 12 + (2×16)
= 12 + 32
= 44 g/mol
Mass of CO₂ from the balanced equation = 1 × 44 = 44 g
SUMMARY:
From the balanced equation above,
64 g of O₂ reacted to produce 44 g of CO₂.
Finally, we shall determine the mass of CO₂ produced by the reaction of 35 g of O₂. This can be obtained as follow:
From the balanced equation above,
64 g of O₂ reacted to produce 44 g of CO₂.
Therefore, 35 g of O₂ will react to produce = (35 × 44)/64 = 24.06 g of CO₂.
Thus, 24.06 g of CO₂ were produced from the reaction.

What would be the mass of 3 moles of water molecules?
a
54 grams
b 40 grams
C
30 grams
d 20 grams
Answer:
[tex]\boxed {\boxed {\sf A. \ 54 \ grams }}[/tex]
Explanation:
To convert from moles to grams, we must use the molar mass.
Recall that water's molecular formula is H₂O. It contains hydrogen and oxygen. Look up the two elements masses on the Periodic Table.
Hydrogen (H): 1.008 g/mol Oxygen (O): 15.999 g/molNow, use these masses to find water's mass. The subscript of 2 tells us there are 2 atoms of hydrogen, so we multiply hydrogen's mass by 2 and add oxygen's.
H₂O= 2(1.008 g/mol) + 15.999 g/mol = 18.015 g/molUse the molar mass as a ratio.
[tex]\frac{18.015 \ g \ H_2 O}{ 1 \ mol \ H_2 O}[/tex]
Multiply by the given number of moles.
[tex]3 \ mol \ H_2O*\frac{18.015 \ g \ H_2 O}{ 1 \ mol \ H_2 O}[/tex]
The moles of water will cancel.
[tex]3 *\frac{18.015 \ g \ H_2 O}{ 1 }[/tex]
[tex]3 *{18.015 \ g \ H_2 O}[/tex]
[tex]54.045 \ g \ H_2O[/tex]
Round to the nearest whole number. The 0 in the tenth place tells us to leave the number as is.
[tex]54 \ g \ H_2O[/tex]
There are about 54 grams of water in 3 moles.
Answer:
54 grams
Explanation:
First step is to find what one mole of water is in grams.
Water is H2O so that means we have two moles of Hydrogen.
H - 2 grams (on periodic table)
We have one mole of Oxygen.
O - 16 grams (on periodic table)
Add 2 and 16 to get 18 total grams in one molecule of H2O
Now multiply 3 times 18 to know how many grams in 3 moles of H2O
You end with
3x18=54 grams

If a substance is a bad conductor as a solid, but a good conductor as a liquid or when dissolved into water, which type of bond is holding the compound together?
The bond type in the substance is ionic bonding because, ionic compounds in their solid state are not conducting but the ions they furnish when dissolved in water conducts electricity.
What are ionic compounds ?Ionic compounds are formed between metals and nonmetals. Metals are electropositive and they can easily loss electrons to from cations. Metals donate electrons to the electron deficient non metals to achieve octet.
Ionic bonding is a strong electrostatic force between opposite charged ions. Hence this bond is stronger than other types of bond. This intact bonding make them bad conductors in the solid state.
However they are electrically conducting the molten state or when dissolved in water due to the presence of free ions and electrons in the solution.

what are the steps to naming simple ionic compounds
Answer:
To name an ionic compound, you simply need to find the names of the cation and anion present in the compound and make sure to revise the ends of metal names as needed. First, write out the name of the metal, followed by the name of the non-metal with its new ending.
