Answer:
A
Explanation:
A. is correct
A chemical change is one in which a new substance is formed. To check if there is a chemical change when the two liquids were combined, what we simply need to do is to see if there is the formation of a new substance. The new substance formed is expected to be chemically and physically distinctive from its formative members.
B is incorrect
Being pure or impure does not provide any information if a chemical change had occurred or not.
C is incorrect
The toxicity of both doesn’t provide any information as regards if a chemical change had occurred or not
D is incorrect.
An outline is a line drawn around an element, enclosing the element content, padding, and border spaces.
A form or figure's outline is defined by a line or combination of lines. The lines restrict the shape, isolating it inside the composition or the area. The shapes are created by the outlines.
The phrase "outline" in art refers to the lines, real or apparent, that define or confine a figure (or shape) within the field of vision, with the total number of these lines defining the contour of the figure.
An item is depicted by lines of contour without shade in an outline sketch or drawing, leaving out internal detail. A variety of markers are used to transform an object's seeming edge into a useful reference on paper.

<u>Answer</u>:
physical property is related to the use of Activated charcoal in gas masks is Physical adsorption
<u>Explanation</u>:
Respirators in the gas masks has a 2-stage inhalation protection process . In the first step, particle filter is used that behaves like a physical barrier that removes bacteria from air which is inhaled. When the bacteria is inhaled, it gets entangled in the filter fibres preventing it from being inhaled into the lungs.
In the next stage , activated charcoal is used .This layer with highly porous charcoal attracts and binds to toxins. Through adsorption process, a solid or a liquid can trap particles on its surface. Toxins that pass through the charcoal become bonded to its surface, preventing inhalation of the toxins.

Explanation:
Answer is 1.67 moles of glucose.
<em>Explanation :</em>
With the presence of oxygen glucose produces CO₂ and H₂O.
The balanced equation is
C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + 6H₂O(l)
The stoichiometric ratio between C₆H₁₂O₆(s) and 6O₂(g) is 1 : 6.
Hence,
moles of C₆H₁₂O₆(s) reacted = moles of reacted O₂(g) / 6
= 10.0 mol / 6
= 1.67 mol
