Cu + 2HCI → Cu²⁺ + 2CI⁻ + H2(g)
has an overall reduction potential of –0.34 V
The correct option is:
The reaction is not spontaneous and will require energy to proceed.
Since the overall reduction potential is negative,the reaction is not spontaneous and it requires energy to proceed.
You have 1 m³ of wood and 1 m³ of aluminum.
Aluminum is the heavier material with a higher density.
What is density?
The mass-to-volume ratio, or mass per unit volume, is known as density. It assesses how much material an object contains in relation to its volume (cubic metre or cubic centimeter). In essence, density is a measurement of how closely together matter is packed.
<u>Density of the wood =1500kg/1m³ = 1500kg/m³ ⟹ 1m³ has a mass of 1500kg Density of Aluminum(Al) =2700kg/m³ = 2700kg/m³⟹ 1m³ has a mass of 2700kg </u>
Therefore, Aluminum is the heavier material with a higher density.

1 mole ----------- 22.4 L ( at STP )
3.75 moles ----- ?
3.75 x 22.4 / 1 => 84.0 L
When there’s water in a department such as a lake, pound or/and ocean, the water tends to evaporated into the air and that’s how/when clouds are created. The same water from those locations are the same water that comes from the rain water, it’s a cycle that creates and takes water
The molar mass of O2 is 32g/mol. So the mol amount of these O2 is 56/32=2 mol. STP stands for the standard temperature and pressure which means the temperature is 0 ℃ and pressure is 100 kPa. And the molar volume of gas is 22.7 L/mol under STP. So the answer is 22.7*2=45.4 L
