Balance NaOH + H2SO4 = Na2SO4 + H2O Using Inspection The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. To be balanced, every element in NaOH + H...
The balanced equation will be calculated along with the solubility states, complete ionic equation, net ionic equation, spectator ions and precipitates. 元素中的第一个字符使用大写字母,第二个字符使用小写字母。例子:Fe, Au, Co, Br, C, O, N, F。 替换不可改变的组以避免歧义。例如,C6H5C2H5 +...
它也是一种强酸碱反应,因为硫酸是一种强酸,氢氧化钠(NaOH)是一种强碱。钠和硫酸之间的反应经常在实验室中用于产生氢气(H2)进行各种实验。 例如,如果我正在进行一个产生氢气的实验,我会将一小块钠金属加入含有硫酸的烧杯中。随着钠与酸的反应,我会观察到气泡的产生,这表明氢气的释放。我还会注意到白色沉淀物的...
How many grams of NaOH are needed to make 750 mL of a 4.25 M NaOH solution? How many milliliters of a 10.6 M NaOH solution are required to prepare a 0.715 L solution of NaOH with a concentration of 0.550 M? How ma...
To be balanced, every element in H2SO4 + Pb(OH)4 = H2O + Pb2(SO4)4 must have the same number of atoms on each side of the equation. When using the inspection method (also known as the trial-and-error method), this principle is used to balance one element at a ...
To be balanced, every element in KMnO4 + H2SO4 + Na2O2 = H2O + O2 + K2SO4 + MnSO4 + Na2SO4 must have the same number of atoms on each side of the equation. When using the inspection method (also known as the trial-and-error method), ...
H2SO4 = K2O4S + HI must have the same number of atoms on each side of the equation. When using the inspection method (also known as the trial-and-error method), this principle is used to balance one element at a time until both sides are equal and the chemical equation is balanced....

a = 1 (NaCH3COO) b = 1 (H2SO4) c = 1 (CH3COOH) d = 1 (NaHSO4) Step 4: Substitute Coefficients and Verify Result Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balan...
Since there are an equal number of atoms of each element on both sides, the equation is balanced. 2AlO + H2SO4=2HO + Al2SO4 AlO+H2SO4 = HO+Al2SO4 ReactantsProducts Al12❌ O55✔️ H21❌ S11✔️ Hint: The sum of the balanced coefficients is 6.See Step-By-Step Solutio...
