What else can I help you with?
When you heat copper oxide and magnesium why do you get grey powder?
You get a grey powder because magnesium is higher up in the reactivity series than Copper - (magnesium is more reactive than copper) therefore when you heat it up there is a displacement reaction. That grey powder is actully magnesium oxide and copper e.g Copper oxide + magnesium = magnesium oxide and copper.
Can calcium displace from magnesium?
Yes, calcium can displace magnesium in certain chemical reactions. This is more likely to happen when calcium is in a higher oxidation state than magnesium, allowing it to take the place of magnesium in a compound or reaction.
Magnesium carbonate plus nitric acid equals?
The most likely reaction is the formation of magnesium nitrate, carbon dioxide, and water.
Is breaking bonds in a chemical reaction more likely to be exothermic or endothermic?
Breaking bonds in a chemical reaction is more likely to be endothermic, meaning it requires energy input to break the bonds.
What would most likely result in the greatest decrease in the rate of a chemical reaction?
Decreasing the temperature or changing the concentration of the reactants would most likely result in the greatest decrease in the rate of a chemical reaction. These changes affect the collision frequency and energy of the reacting molecules, slowing down the overall reaction rate.
What is the chemical formula of the magnesium and fluorine reaction product?
Mg + F2 => MgF2 (Magnesium fluoride, salt, soluble in water)metal + gas .. saltMgF2

What chemical change is most likely to involve bubbling or an odor?
This is a chemical reaction.
What happens when you mix hydrogen gas with magnesium?
When hydrogen gas is mixed with magnesium, a chemical reaction occurs where the magnesium metal reacts with the hydrogen gas to form magnesium hydride. This reaction is highly exothermic, meaning it releases a significant amount of heat. The chemical equation for this reaction is 2Mg + H2 -> 2MgH2.
Is breaking bonds in a chemical reaction more likely to be exothermic or endothermic?
Breaking bonds in a chemical reaction is more likely to be endothermic, meaning it requires energy input to break the bonds.
If the chemical properties of the substance have not changed has a chemical reaction occurred?
It depends: just try to relate, try to write a chemical equation for and see if there are byproducts. Most likely, if the same chemical still has its same properties After the reaction, a chemical reaction has not occurred.
Which elements are likely to gain electrons?
Since chemical reaction............<3
A chemical reaction that gives off heat is most likely to be what?
An endothermic reaction is one that consumes heat.
What would most likely result in the greatest decrease in the rate of a chemical reaction?
Decreasing the temperature or changing the concentration of the reactants would most likely result in the greatest decrease in the rate of a chemical reaction. These changes affect the collision frequency and energy of the reacting molecules, slowing down the overall reaction rate.
Is H2O plus Mg a mixture?
No, H2O plus Mg does not form a mixture. Mixing water (H2O) with magnesium (Mg) would not result in a homogenous combination of substances. Instead, the magnesium would likely react with the water, producing magnesium hydroxide (Mg(OH)2) and hydrogen gas (H2).
