Answer:
None
Explanation:
Cl₂ is above Br₂ in the activity series.
Bromine will not displace chlorine from its salts.
The reaction will not occur.
Manipulated variable: the types of soil
Responding variable: how much t the plants grow
Answer:
0.752 J/g*K
Explanation:
The heat lost by the alloy (which is negative) must be equal to the heat gained by the water and the coffee cup:
-Qa = Qw + Qc
-ma*ca*ΔTa = mw*cw*ΔTw + C*ΔTc
Where, m is the mass, c is the specific heat capacity, C is the heat capacity of the coffee cup, ΔT is the change in temperature, a represents the alloy, and w the water.
The coffee cup has initial temperature equal to the water, then:
-30.5*ca*(31.1 - 95.0) = 49.3*4.184*(31.1 - 24.3) + 9.2*(31.1 - 24.3)
1948.95ca = 1465.20
ca = 0.752 J/g*K
The answer is <span>the
reaction will shift to the left (toward the reactants).
Reaction is at equilibrium can be expressed as,
Reactants </span>⇄ products<span>
<span>After coming to the equilibrium, if one condition
is changed, then according to the </span>Le chatelier's Principal,<span> the system
will act to maintain the equilibrium by reducing the effect. As an example, if
we reduce the pressure, then system acts to increase the pressure to maintain
the equilibrium.</span>
<span>Likewise, if we add products into the reaction
which is in equilibrium, the system acts to reduce the effect by promoting the backward
reaction to produce reactants.</span></span>
