Find the sum of 8a –2b + 3c and –3a +4b –3c
2 answers:
Answer: 5a + 2b
Step-by-step explanation:
<u>Given</u>
(8a - 2b + 3c) + (-3a + 4b - 3c)
<u>Expand parentheses</u>
=8a - 2b + 3c - 3a + 4b - 3c
<u>Put like terms together</u>
=(8a - 3a) + (4b - 2b) + (3c - 3c)
<u>Combine like terms</u>
=5a + 2b + 0
=

Using an ideal gas equation to solve the problem. Then the original volume is 17.67 liters.
<h3>What is an ideal gas equation?</h3>An ideal gas is a theoretical composed of a set of randomly moving gas particles that interact only through elastic collision.
Given
A balloon containing 0.500 mol at 0. 00°C and 65.0 kPa pressure are expanded by adding more argon.
Pressure (P) = 65 kPa
Mole (n) = 0.5 mol
Temperature (T) = 0 °C = 273.15 K
Universal gas constant (R) = 8.317 L.kPa/mol.K
We know the ideal gas equation
Put the values, we have
Thus, the original volume is 17.67 liters.
