Normally for these types of questions (2 different situations), you can use:
P*V/T = P*V/T
As long as you don't confuse the different values up
Since V is constant, you can say that P/T (before heating up) = P/T (after heating up)
So 75000/295 = P/418
<span> a) AgNO3 (aq) + KCl (aq) --> AgCl (s) + KNO3 (aq) this is balanced chemical equation
</span><span>AgCl is the precipitate so we shall not split it
</span><span>Ag+(aq) + NO3 -(aq) + K+ (aq) + Cl-(aq) --> AgCl (s) + K+(aq) + NO3-(aq)
</span><span>Ag+ (aq) + Cl- (aq) ---> AgCl (s) after removing ions</span>
Answer:
6750 J
Explanation:
The specific heat capacity of iron is 450 J/kg/K
Quantity of heat = mcθ; where m is the mass and c is the specific heat capacity and θ is the temperature change.
Therefore;
m = 3 kg, c = 450 J/kg/K and θ = 5°C
Quantity of heat = 3 × 450 × 5
<u>= 6150 Joules</u>
<span>The organizational characteristics of the periodic table of the elements are within a system where all known elements are classified. They are placed from left to right and top to bottom in increasing order of their atomic numbers. The elements are arranged in seven horizontal rows called periods, and in 18 vertical columns called groups or families. Down and to the left increases the atomic radius and the ionic radius. Upwards and to the right increases ionization energy, electron affinity and electronegativity.</span>
