Answer:
So you should go and try to divide or smth or multiply
The grams of water needed to react with 44.9 grams of Li2O is calculated as follows
write the equation for reaction
Li2O +H2O = 2LiOH
find the moles of Li2O = mass/molar mass
= 44.9/29.9 = 1.5 moles
by use of reacting ratio between Li2O to H2O which is 1:1 the moles of H2O is therefore = 1.5 moles
mass is therefore = moles x molar mass
= 1.5 mol x 18 g/mol = 27 grams
The phase shift in the events is called deposition.
In a vacuum, carbon atoms in gas form a diamond coating on a surface. The conversion of gas phase to solid phase is a part of the described process. As a result, this procedure is known as deposition.
A deposition is a process by which a solid substance is formed from a gaseous one. Bypassing the transitional liquid state, a gaseous substance is deposited in its place (often as crystals). Deposition happens, for instance, when airborne water vapor quickly freezes into ice, as when frost develops.
<h3>
How does deposition occur?</h3>
Whether the eroding agent is gravity, ice, water, waves, or wind, deposition happens when it runs out of energy and can no longer support the burden of the degraded material. Gravity or, in the case of wind, the Sun, provides the energy that the erosion agents can use.
