Pb(NO3)2(aq) + K2SO4(aq) --> PbSO4(s) + 2KNO3(aq)
<span>Total ionic equation: </span>
<span>Pb 2+ (aq) + 2NO3- (aq) + 2K+ (aq) + SO4 2- (aq) ---------> PbSO4 + 2K+ (aq) + 2NO3- (aq) </span>
<span>For the net ionic equation cancel out species found on both sides to get: </span>
<span>Pb 2+ (aq) + SO4 2- (aq) ----------> PbSO4(s) </span>
<span>Note aqueous species dissolve and are separated into their ions but solid ones do not and simply precipitate out of solution.</span>
Answer:
Water
Explanation:
Given the specific heat of oxygen is 918J/kg°C and the specific heat of water is 4181 J/kg°C.
Consider 1Kg mass of each substance.
Now 1 Kg of oxygen needs 918 J of energy to raise its temperature by 1°C
Also 1 Kg of water needs 4181 J of energy to raise its temperature by 1°C.
Clearly water recquires more energy when compared to oxygen.
Basically specific heat capacity is the amount of energy recquired to raise the temperature of a 1 kg body by 1°C.
Hi there. I suggest doing this yourself but here are my answers in my own words
1) Using renewable resources might be an amazing choice due to the fact that there will be less pollution. If humans continue using non-renewable resources, humans will make the oxygen contaminated. Also, renewable resources will never run out so there isn't any harm getting them
2) The environmental impact of using non-renewable resources is that more carbon dioxide will be released which causes pollution which is harmful to the human body. Renewable resources are unlimited and don't cause any pollution
Answer:
Explanation:
Hello,
In this case, for the given constant amount and pressure of the, we apply the Charles' law which allows us to understand the volume-pressure behavior as a directly proportional relationship:
Thus, since we need to compute the volume after the temperature increase (which must be expressed in absolute Kelvins), we obtain V2 as:
Best regards.
sorry i don't know the answer i'm really sorry
