Answer:
So there is83.6g CO2 produced
Explanation:
Burning carbon with air has the following equation
C + O2 → CO2
For 1 mol Carbon, we have 1 mol O2 and 1 mol CO2
Step 2: Calculating moles
mole C = 22.8g / 12g/mole
Mole C = 1.9 mole
1.9 mole C will completely react
Since for each mole C there is 1 mole O2 and 1 mole CO2
This means there will also react 1.9 mole of 02, to be formed 1.9 mole of CO2
mole CO2 = mass CO2 / Molar mass CO2
mass CO2 = 1.9 mole CO2 * 44g/mole =<u>83.6g CO2</u>
In this reaction 18.2 g of O2 remained unreacted
we can control this: 79g - 18.2 g = 60.8g
1.9 mole * 32g/mol = 60.8g
So there is83.6g CO2 produced
Answer:
Number of moles = 10.6 mol
Explanation:
Given data:
Molar mass of H = 1.008 g/mol
Molar mass of C = 12.01 g/mol
Molar mass of O = 16.00 g/mol
Mass of citric acid = 2.03 kg (2.03×1000 = 2030 g)
Number of moles of citric acid = ?
Solution:
Formula:
Number of moles = mass/molar mass
Now we will calculate the molar mass of citric acid:
C₆H₈O₇ = (12.01× 6) + (1.008×8) + (16.00×7)
C₆H₈O₇ = 72.06 + 8.064+112
C₆H₈O₇ = 192.124g/mol
Number of moles = 2030 g/ 192.124g/mol
Number of moles = 10.6 mol
The total charge on an atom comes from protons and electrons.
The proton is positively charged while the electron is negatively charged. A neutral atom would have an equal number of protons and electrons.
An atom with more protons than electrons will be positively charged while those with more electrons than protons will be negatively charged.
