Hot to cold
Explanation:
Unless people interfere, thermal energy or heat naturally flows in on direction only: hot towards cold. Heat moves naturally by any of three means. The processes are known as conduction, convection, radiation. Sometimes more than one may occur at the same time.
Answer:
Neutrons play no role in the net charge of an atom, so you can ignore them here.
Proton = 7
Electron = 10
Net Charge = 7 - 10
= -3
Again,
Proton = 3
Electron = 2
Net Charge = 3 - 2
= 1
I believe its C because 7.5 would be considered a base and when acid it’s added it’s PH neutralizes the solution
A single-replacement reaction is a chemical reaction in which one element is substituted for another element in a compound, generating a new element and a new compound as products.
A double-replacement reaction occurs when parts of two ionic compounds are exchanged, making two new compounds. A characteristic of a double-replacement equation is that there are two compounds as reactants and two different compounds as products.
The key difference between single displacement and double displacement reaction is that, in single displacement reactions, one chemical species replaces a part of another chemical species whereas, in double displacement reactions, exchange of two ionic species between two molecules occur.
Hope this helps you.
