What else can I help you with?
Which of the equations below is an example of a thermochemical equation a Mg plus 2H3O plus plus Cl- --- Mg2 plus plus 2Cl- plus H2 plus h20 b 2H2 G plus 2O2 G ----H2O g plus 483.6kj c 2H2 G plus 2O2?
The equation c) 2H2 (g) + O2 (g) → 2H2O (g) is an example of a thermochemical equation because it shows the reactants and products with energy change included, but it doesn't explicitly mention the heat added or released during the reaction.
What is the balanced equation for hno3 plus nahco3-nano3 plus H2O plus CO2?
The balanced equation for the reaction between HNO3 and NaHCO3 is: 2 HNO3 + NaHCO3 → NaNO3 + H2O + CO2
Is ice a mixture or compound?
Ice is a pure substance, not a mixture or compound. Ice is the solid form of water, with a chemical formula of H2O. It is made up of water molecules arranged in a crystal lattice structure.
Will kcl and h2o form a homogeneous mixture?
Yes, potassium chloride (KCl) can dissolve in water (H2O) to form a homogeneous mixture. This solution will be transparent and uniform, with the KCl ions evenly distributed throughout the water molecules.
What is the balanced equation for Mg plus CuSO4?
the produc of the reaction is Mg(s) + CuSO4 (aq)--> MgSO4(aq) + Cu(S)+H2 ***NOTE**** the H2 is coming from CuSO4 in a aqueous solution, thus H2O is involved in the reaction. I believe that this would make the precipitate call Copper (II) Oxide. Thus, shouldn't the equation be..... Mg(s) + CuSO4 (aq) --(H2O)--> MgSO4 (aq) +CuO (s) + H2 (g) N.B. Hi Classmates! Galingan ninyo ang paggawa ng seatwork natin ha. Copy nalang ako sa inyo
What is a mixture of a element and a compound?
What is a mixture of a element and a compound? CO + Co Fe + Mg H2O + Mg N2 + O2 H2O Plz answer it can be more than 1
What is the balanced equation for Mgo plus H2O?
The balanced equation for MgO + H2O is MgO + H2O -> Mg(OH)2.
Complete the balance MgO plus H2O?
The reaction is:MgO + H2O = Mg(OH)2
NaCl plus H2O a mixture or compound?
Not, its a homogeneous solution (a mixture).
What yields from Mg plus C3H8?
At sufficiently high temperature, Mg + H2O = MgO + H2.
Is NaCl plus H2O a compound or mixture?
Sodium chloride and water form a solution, a homogeneous mixture not a compound.
Is NaCl plus H2O a mixture?
Yes. When NaCl is added to water, it forms a solution, which is a homogeneous mixture.
Is H2O mg a mixture?
These are actually the reactants in a chemical reaction. Magnesium reacts slowly with water to produce hydrogen gas and magnesium hydroxide. Mg + 2H2O --> Mg(OH)2 + H2
Is water (H2O) a mixture?
It is a compound. H2O
Is a sugar dissolve in h2o a pure substance or a mixture?
Sugar dissolved in H2O is a mixture
Which if these are a molecule Ca Mg Na H2O?
H2O. Notice the presence of two elements, H and O. Each of the other three is an element.
Is h20 and mg an element?
Yes, H2O is a compound made up of the elements hydrogen and oxygen. Mg, on the other hand, is the chemical symbol for the element magnesium.
