Answer:
Baking soda is an alkaline, or base, substance. This means that when we dissolve baking soda in water, it forms an alkaline solution. For example, a 0.1 molar solution of baking soda has a pH of around 8.3. Lemon juice contains citric acid and has a pH of around 3.
The given 2 triangles are similar
Explanation:
Step 1 :
Given,
ABC is a triangle
N is the point on AB so that ∠ABC = ∠ ACN
We need to show that the triangles ABC and ACN are similar
Step 2 :
Two triangles are said to be similar if the corresponding angles are equal.
In the given triangles we have
∠A as the common angle
∠ABC = ∠ ACN
Since 2 angles of both the triangles are same, the third angle is also same, because the sum of the measures of all angles is 180 degrees
Hence the given 2 triangles are similar

Answer:
Hypsochromic compound, More polar solvent
Explanation:
Hypsochromic shift refers to the shift of solution colour to blue side of the visible spectrum (blueshift) with increasing polarity of the solvent. In our case, the solution changes to orange colour from red when solvent is changed. This means that the emission spectrum of the solution underwent blueshift. (As orange colour is on the 'blue' side for red colour.) So this is a hypsochromic shift, and the new solvent is more polar that the previous one, as it caused hypsochromic shift.
