Which is a non oxy-acid?A sulfuric acidB. nitric acidC. hydrofluoric acidD. phosphoric acid The correct answer and explanation is : The correct answer is: C. Hydrofluoric acid Explanation: Acids are broadly classified into two main categories based on their composition: Since hydrofluoric acid (HF) contains only hydrogen and fluorine and no oxygen, it is classified

Which is the correct chemical name for CuCIO?A. copper (III) chlorateB. cupric chlorateC. cuprous chlorateD. cupric perchlorate The correct answer and explanation is : The correct answer is: C. cuprous chlorate Explanation: The compound CuClO is composed of copper (Cu) and the chlorate ion (ClO⁻). To name this compound correctly, we need to determine the

What is the chemical name of Hg2SO4 using the new method?A. mercurous sulfateB. mercury (1) sulfateC. mercury (II) sulfateD. mercurous sulfite The correct answer and explanation is : The correct answer is: B. mercury (I) sulfate Explanation (300 words): To determine the correct chemical name for Hg₂SO₄, we need to follow the IUPAC nomenclature guidelines

A sample containing the amino acid alanine, CH3CH(NH2)COOH, plus inert matter is analyzed by the Kjeldahl method. A 2.00-g sample is digested, the NH3 is distilled and collected in 50.0 mL of 0.150 M H2SO4, and a volume of 9.0 mL of 0.100 M NaOH is required for back-titration. Calculate the percent alanine in the

Determine the theoretical yield in H2S (in moles) of 16 mol Al2S3 and 16 mol H2O are reacted according to the following balanced reaction. A possibly useful molar mass is Al2S3 = 150.17g/mol. Al2S3(s) + 6H2O(l) –> 2Al(OH)3(s) + 3H2S(g) The correct answer and explanation is : To determine the theoretical yield of hydrogen sulfide

Which is a salt of an oxy acid?A. sodium sulfateB. magnesium chlorideC. boron nitrideD. carbon dioxide The correct answer and explanation is : The correct answer is A. sodium sulfate. Explanation: To understand why sodium sulfate is the salt of an oxyacid, we need to break down the concepts involved. Now let’s look at the

Which is not a binary acid?A. hydrochloric acidB. hydrobromic acidC. hydroiodic acidD. none of the above The correct answer and explanation is : The correct answer is D. none of the above. Here’s why: Binary acids are acids that consist of only two elements: hydrogen and one other nonmetal. The formula of binary acids is
