Column A
baherus [9]

Answer:

The Following are the matching to this question:

1 \to c\\2 \to  b\\3 \to   a\\4   \to  e \\5 \to  d    \\6 \to  f

Explanation:

  1. It includes creating assumptions, extracting predictions through logical outcomes, and experimentation observation based on those projections.  
  2. Every information gathered only with sense is also an observation. It expresses concern relating to scientific research. It also helps research scientists gather data.  
  3. Its independent variable inside an analysis is a controlled variable. It's also called "manipulated," because it can change its parameter, which is controlled one.  
  4. The suggested explanation for an occurrence is a hypothesis. It belongs to the scientific method. That's an experimental forecast, which is checked.  
  5. The experiment manipulates the important variables, calculates the dependent variable, controls any alien variables.
  6. It "reacts" to improvements inside an experiment that they make. It is the result or consequence of an experiment.

Phosphorous +Dilute hydrochloric acid
butalik [34]

Phosphorus trichloride is the precursor to organophosphorus compounds that contain one or more P(III) atoms, most notably phosphites and phosphonates. ... PCl3 reacts vigorously with water to form phosphorous acid, H3PO3 and HCl: PCl3 + 3 H2O → H3PO3 + 3 HCl.

The hydrogen ion concentration is 1 × 10-7. What is the ph of this solution?
Naya [18.7K]

Answer:

  • <em>The pH of the solution is </em><u><em>7</em></u>

Explanation:

<em>The pH</em> is a measure of the acidity of the solutions. It is defined as the negative logarithm of the molar concentration of hydrogen ions (H⁺).

  • pH = - log [H⁺]

<em>The hydrogen ion concentration of this solution is 1 × 10⁻⁷ M.</em>

Hence:

  • pH = - log (1 × 10⁻⁷) = - (-7) = 7

This pH corresponds to a neutral solution (neither acid nor alkaline).

You should remember this relation bwtween pH and acidity/alkaliinity:

  • Low pH (0.0 or close) corresponds to strong acids
  • HIgh pH (14.0 or close) corresponds to strong bases
  • Acids have pH between 0.0 and 7.0
  • Bases have pH between 7.0 and 14.0
