Answer: solid.
Explanation:
Precipitate is the solid substance produced during a chemical reaction carried out in a solution.
The precipitate is formed when the reactants in a chemical reaction, which are in solution, form a compound that is insoluble, and so it cannot stand dissolved but precipiates, normally going to the bottom of the vessel, in solid form.
The phases in a chemical equation are indicated using letters inside parenthesis placed to the right of the chemical formula of each compound or element.
These are the common uses: s for solid, aq for aqueous solution, l for liquid, and g for gaseous.
This is an example:
2 NaOH (aq) + CuCl₂ (aq) → 2 NaCl (aq) + Cu (OH)₂ (s)
The phases are:
- Reactant side: NaOH and CuCl₂ are dissolved in water, which is indicated by the the word aq, meaning aqueous.
- Product side: NaCl is aqueous, and Cu(OH)₂ is in solid form, meaning that it is a precipitate.
I'm pretty sure the answer is Temperature
Answer:
S(metal) = 0.66J/g°C
Explanation:
We can find specific heat of a material, S, using the equation:
q = m*S*ΔT
<em>Where q is change in heat, m is the mass of the substance, S specific heat and ΔT change in temperature.</em>
The heat given by the metal is equal to the heat that water absorbs, that is:
m(Metal)*S(metal)*ΔT(Metal) = m(Water)*S(water)*ΔT(water)
<em>Where:</em>
m(Metal) = 76.0g
S(metal) = ?
ΔT(Metal) = 96.0°C-31.0°C = 65.0°C
m(Water) = 120.0g
S(water) = 4.184J/g°C
ΔT(water) = 31.0°C-24.5°C = 6.5°C
Replacing:
76.0g*S(metal)*65.0°C = 120.0g*4.184J/g°C*6.5°C
S(metal) = 0.66J/g°C
<em />
The law of conservation applies because the energy is not been created or destroyed. The energy that the metal gives is absorbed by the water.
Answer: 1 mol of 
will be produced from this reaction.
Explanation: Reaction follows,
As seen from the balanced chemical equation above, we get
For every 3 moles of Aluminium and 3 moles of 
, 1 mole of 
is formed.
For every 3 moles of Aluminium and 3 moles of , 1 mole of is formed.
For every 3 moles of Aluminium and 3 moles of , 3 moles of 
is formed.
For every 3 moles of Aluminium and 3 moles of , 6 moles of 
is formed.
