The statement that correctly describes the reaction is: Tungsten (W) changes oxidation numbers from +6 to zero, so it undergoes reduction.
<h3>WHAT IS
OXIDATION AND REDUCTION:</h3>
- Oxidation is the process whereby electrons are lost in a reaction while reduction involves the gain of electrons.
- According to this question, the following reaction is given: WO3(s) + 3H2(g) → W(s) + 3H2O(g)
- Tungsten has an oxidation number of +6 in WO3 and it is changed to 0 in W, hence, there is a gain of electrons by tungsten (W).
Therefore, the statement that correctly describes the reaction is: Tungsten (W) changes oxidation numbers from +6 to zero, so it undergoes reduction.

Answer:
because of it being that you have inferno dragon plsss
The ideal gas equation is PV = nRT. if you are looking
for the volume of the chlorine gas then the equation will turn out to be V =
nRT/P. At STP, temperature is 273K and pressure is 1 atm.
V = nRT/P
V = (1.5 moles Cl2)(0.08206 L-atm/mol – K)(273K) / (1atm)
V = 33.6 liters
Answer:
b : they move to the positive electrode
Explanation:
they lose electrons to form chlorine atoms. The atoms join up in pairs to form Cl² molecules , so chlorine gas is formed at the positive electrode
Cu and atomic number 29. copper is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.
