Answer:
Ozone is a gas made up of three oxygen atoms (O3). It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). Ozone protects life on Earth from the Sun's ultraviolet (UV) radiation.
At STP, copper (Cu) would be the only substance here that will exist in the solid state.
<h2>Collision Theory
</h2>
Explanation:
<h3>
The given statement is related to the collision theory -
</h3>
Collision theory was given by William Lewis in 1916.
This theory explains in a qualitative manner that in what way any chemical reaction occurs and the reason for the different reaction rates for different reactions.
<h3>
According to the collision theory -
</h3>
- Molecules must collide in order to react
- Sufficient amount of energy is needed for collisions (kinetic energy) so that the chemical bonds should break
- This energy used is known as the activation energy
- On the increase in the temperature, the kinetic energy of the molecule increases and the molecules move faster and collide with a proper orientation at an increased speed
- This increases the rate of a collision that in turn increases the breaking of the bond
Hey there !
Molecular Weight: 262.86 g/mol
Volume in liters : 1,000 mL => 1,000 / 1000 => 1 L
Number of moles of solution :
number of moles = volume x molarity
number of moles = 1 x 0.3 => 0.3 moles
Therefore:
1 mole Mg₃(PO₄)₂ ------------------- 262.86 g
0.3 moles ----------------------------- mass of Mg₃(PO₄)₂ ??
mass of Mg₃(PO₄)₂ = 0.3 x 262.86 / 1
mass of Mg(PO₄)₂ => 78.858 g
Hope this helps!
