Answer:
100Jkg/°C
Explanation:
Given parameters:
Mass of metal = 2kg
Amount of heat energy = 1600J
Initial temperature = 5°C
Final temperature = 13°C
Unknown:
Specific heat capacity of the metal = ?
Solution:
Specific heat capacity of a body is the amount of heat needed to raise the temperature of unit mass of a body by 1°C.
H = m x C x (T₂ - T₁ )
H is the amount of heat
m is the mass
C is the unknown specific heat capacity
T is the temperature
Insert the parameters and solve;
1600 = 2 x C x (13 - 5)
1600 = 16C
C = 100Jkg/°C
Answer: B. CH₂OH
Explanation:
First off, we need a liquid solvent. Eliminate C and D.
Now, we have to consider polarity.
- Carbon tetrachloride is nonpolar, so sodium chloride will be insoluble.
- CH₂OH is polar, so sodium chloride will be soluble.
Answer:
![5H_2O+C_5H_{10}O_5\rightarrow 5CO_2+20H^++20e^-](https://tex.z-dn.net/?f=5H_2O%2BC_5H_%7B10%7DO_5%5Crightarrow%205CO_2%2B20H%5E%2B%2B20e%5E-)
Explanation:
Hello.
In this case, when ribose (C₅H₁₀O₅) yields carbon dioxide (CO₂) we write:
![C_5H_{10}O_5\rightarrow CO_2](https://tex.z-dn.net/?f=C_5H_%7B10%7DO_5%5Crightarrow%20CO_2)
Which needs to be balanced by adding water and hydrogen ions:
![5H_2O+C_5H_{10}O_5\rightarrow 5CO_2+20H^++20e^-](https://tex.z-dn.net/?f=5H_2O%2BC_5H_%7B10%7DO_5%5Crightarrow%205CO_2%2B20H%5E%2B%2B20e%5E-)
You can also see that there are 20 transferred electrons, since the carbon atoms in the ribose have 0 as their oxidation state and the carbon atoms in the carbon dioxide have +4 as the oxidation state, thus, each carbon transfers 4 electrons, a five carbon atoms transfer 20 electrons overall.
In such a way, since the carbon is increasing its oxidation state, such half reaction is an oxidation half reaction.
Best regards.
