Answer: Option (b) is the correct answer.
Explanation:
According to ideal gas law, the product of pressure and volume is equal to the product of number of moles, gas constant and temperature.
Mathematically, PV = nRT
So, when there are two gases with equal number of moles behaving ideally then the ideal gas equation will be as follows.
=
and =
Hence, when temperature and pressure of both the gases will be constant then = 1.
Thus, we can conclude that constant temperature and pressure is the conditions that must be met for a volume ratio to be created from a balanced chemical equation.
Answer:pure water is neutral . Lake water is acidic. Baking soda and soapy water are basic.
Explanation: 7 is neutral. The higher on the ph scale like 1-6 is acidic. The lower on the scale 8-13 is base or alkaline.
A kelp forest is an ecosystem in itself. Many animals use these massive forests to shelter their young from predators. Other animals feed off of the kelp plants. When you understand how marine life lives with the kelp forests you can begin to understand the big picture.
Answer: A) 67.1 moles
Explanation:
The balanced reaction is :
To calculate the moles, we use the equation:
According to stoichiometry;
2 moles of iron is produced by 3 moles of carbon monoxide
89.3 moles of iron is produced by= moles of carbon monoxide
2 moles of carbon monoxide is produced by = 1 mole of oxygen
Thus 134 moles of carbon monoxide is produced by = moles of oxygen
Answer:
Convection
Explanation:
Convection is the transfer of thermal energy by particles moving through a fluid.
