Answer:
Difference in temperature
Explanation:
According to thermodynamics, heat transfer occurs when heat from a high temperature reservoir moves to a low temperature reservoir. For heat to be transferred, the two objects should have different temperatures with one having more temperature than the other. Heat transfer in solids is by conduction, in fluids is by convection and by radiation.
When a neutral hydrogen atom loses an electron, and positively-charged particles should remain. A proton should be 1840 times heavier than an electrons. Cathode rays should be attracted to a positively- charged plate.
Answer : The temperature in degree Celsius is, 
Explanation :
The conversion used for the temperature from Fahrenheit to degree Celsius is:
where,
= temperature in Fahrenheit
= temperature in centigrade
As we are given the temperature in Fahrenheit is, 451
Now we have to determine the temperature in degree Celsius.
Therefore, the temperature in degree Celsius is,
Answer:
ZnO(s) + 2HCl(aq) ------> ZnCl2(aq) + H2O(l)
Na2O(s) + 2HCl(aq) -----> 2NaCl(aq) + H2O(l)
Rb2O(s) + 2HCl(aq) -----> 2RbCl(aq) + H2O(l)
NiO(s) + 2HCl(aq) --------> NiCl2(aq) + H2O(l)
MgO(s) + 2HI(aq) -----> MgI2(aq) + H2O(l)
Na2O(s) + 2HI(aq) -----> 2NaI(aq) + H2O(l)
CaO(s) + 2HI(aq) ----> CaI2(aq) + H2O(l)
Explanation:
Let us recall that the oxides of metals are basic in nature. These basic metal oxides can react with acids to form salt and water only.
In the reactions above, HCl and HI were reacted with different metal oxides and the corresponding salts of each metal and water was formed as shown.
