Answer:
A
Explanation:
This kind of bond is known as an ionic bond and is based on electrostatic forces between two charged molecules/atoms. To achieve stable configuration, sodium (2.8.1) transfers its valence electron to chlorine that also needs one electron to achieve stable configuration (2.8.8), and combine in an ionic bond.
Answer:
Explanation:
The first step is the <u>calculation of the moles</u> of and , so:
Now, in 1 mol of CO2 we have 1 mol of C and in 1 mol of we have 1 mol of H. Additionally, if we want to calculate the moles of oxygen we need to <u>calculate the grams of C and O</u> and then do the <u>substraction</u> form the initial amount, so:
Now we can <u>convert the grams</u> of O to moles, so:
The next step is to divide all the mol values by the <u>smallest one</u>:
Therefore the formula is
Best Answer: Total number of moles n = PV/RT = (12.5atm x 10L)/(0.082 x 298K) = 5.1154 mole
30g of oxygen = 30g/32g/mol = 0.94 mole. Also 30g of nitrogen = 30g/28g/mole = 1.07 moles.
Let the number of moles of CO2 be = c,
0.94 + 1.07 + c = 5.1154. Hence c = 3.105 mole = number of moles of CO2
Mass of CO2 = 3.105 moles x 44g/mole = 136.62g ~ 137g
It is a neutralization reaction.
