$\huge{ \underline{ \boxed{ \bf{ \green{Answer:}}}}}$

Inside the stomach, Hydrochloric acid kills micro-organisms in the food. Stomach juices begin to break down proteins to amino acids.

✤ So, Fill the blank with proteins.

<h3>Explanation:-</h3>

Inside the stomach, the digestion of proteins starts due to the action of pepsin enzyme.
But this enzyme remains inactive and is activated by the Hydrochloric acid(HCl).
The Hydrochloric acid also helps in killing the germs and microbes which entered along with food.
The mucous lines the wall of stomach to protect it from the harm caused by HCl because HCl is a strong acid.
In stomach, The partial digestion of proteins occur and rest is digested in the small intestine by Trypsin(Pancreatic enzyme) and Intestinal juices.

pickupchik [31]

Answer:

2 HClO₃ + Ca(OH)₂ ---> Ca(ClO₃)₂ + 2 H₂O

Explanation:

This is a double-displacement reaction. In these reactions, the cation of one molecule swaps with the cation of another.

In this case, the hydrogen cation (H⁺) from HClO₃ swaps with the calcium cation (Ca²⁺) of Ca(OH)₂. When writing the products, keep the charges of the ions in mind. The products must be neutral, so some will need to have more than 1 cation/anion.

The unbalanced equation:

HClO₃ + Ca(OH)₂ ---> Ca(ClO₃)₂ + H₂O

Reactants: 3 hydrogen, 1 chlorine, 5 oxygen, 1 calcium

Products: 2 hydrogen, 2 chlorine, 7 oxygen, 1 calcium

The balanced equation:

2 HClO₃ + Ca(OH)₂ ---> Ca(ClO₃)₂ + 2 H₂O

Reactants: 4 hydrogen, 2 chlorine, 8 oxygen, 1 calcium

Products: 4 hydrogen, 2 chlorine, 8 oxygen, 1 calcium

14. If one half-life is the amount of time it takes for a radioactive isotope to decay by a factor of 2,

Rainbow [258]

Answer:

Since the equation for amount remaining is (1/2)^n, where n stand for the number of half lives, after 2.3 half lives the equation is (1/2)^2.3. This makes the answer about 1/4.92, which converts to about 20% of the original amount.
