___Fe2O3 + ___C --> ___Fe + ___ C03 balanced

Chemistry
1 answer:
SashulF [63]3 years ago
5 0

Answer:

Fe2O3 + C → 2Fe + CO3

Explanation:

The unbalanced equation given in this question is as follows:

Fe2O3 + C → Fe + C03

To balance this equation, one should ensure that the number of atoms of each element on both sides of the equation is equal. The balanced equation is as follows;

Fe2O3 + C → 2Fe + CO3

N.B, there are;

- 2atoms of Fe on both sides

- 1 atom of C on both sides

- 3 moles of O on both sides

How is 6.3 written in scientific notation?
Leokris [45]
6.3 × 10^0
In scientific notation, the numerical value without the exponent of 10 must be within the range from 1 to just below 10 (for example, 9.99...). In this case, 6.3 is already within this range, so we just have to multiply it by 1. To get a multiplier of 1 using base 10, we would have to raise 10 to the zeroth power.

1) if I have a 30 mole sample of gas at a temperature of 120˚C, and a volume of 300 L. What is the pressure of the gas on the co
vivado [14]

Answer:

P = 3.23 atm

Explanation:

Given data:

Number of moles of gas = 30 mol

Temperature = 120°C

Volume of gas = 300 L

Pressure of gas = ?

Solution:

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will convert the temperature.

120+273.15 = 393.15 K

P × 300 L = 30 mol × 0.0821 atm.L/mol.K × 393.15 K

P = 968.33 atm. L /300 L

P = 3.23 atm
