Answer: (a) The products are and AgCl. The balanced equation is .
(b) The type of reaction is double displacement reaction.
Explanation:
(a) The complete reaction equation will be as follows.
Number of atoms on reactant side are as follows.
- Be = 1
- Cl = 2
- Ag = 2
- = 2
Number of atoms present on product side are as follows.
- Be = 1
- Cl = 2
- Ag = 2
- = 2
Here, number of atoms on both reactant and product side are the same. Hence, it is a balanced chemical equation.
(b) A reaction in which two reactant species tend to change their ions with each other and form new compounds. This type of reaction is called double displacement reaction.
As the given reaction is as follows.
This shows that ions are being exchanges by the reactants and
. The ions are , , and .
Therefore, this reaction is a double displacement reaction.
Answer:
mudslide
Explanation:
a mass of mud and other earthy material that is falling or has fallen down a hillside or other slope
<span>0.3 liters of volume is required.</span>
Answer:
The metal has a heat capacity of 0.385 J/g°C
This metal is copper.
Explanation:
<u>Step 1</u>: Data given
Mass of the metal = 21 grams
Volume of water = 100 mL
⇒ mass of water = density * volume = 1g/mL * 100 mL = 100 grams
Initial temperature of metal = 122.5 °C
Initial temperature of water = 17°C
Final temperature of water and the metal = 19 °C
Heat capacity of water = 4.184 J/g°C
<u />
<u>Step 2: </u>Calculate the specific heat capacity
Heat lost by the metal = heat won by water
Qmetal = -Qwater
Q = m*c*ΔT
m(metal) * c(metal) * ΔT(metal) = - m(water) * c(water) * ΔT(water)
21 grams * c(metal) *(19-122.5) = -100 * 4.184 * (19-17)
-2173.5 *c(metal) = -836.8
c(metal) = 0.385 J/g°C
The metal has a heat capacity of 0.385 J/g°C
This metal is copper.
