Answer:
Explanation:
1. HCl helps breakdown,absorb and digest food and also destroy bacterias in the stomach.
2. Organic Matter promotes good soil structure and act as reservoir of nutrients in the soil.
3. The nature of the solution is Basic
Reason... Blue litmus will remain blue in a basic solution and turn Red in an acidic solution
4. There's a number of test available for her to use but preferably... She should use the Litmus paper test. That's easier. An acidic solution will Turn a blue litmus red while the blue litmus will retain its blue color in a basic solution.
Answer: :Change in thermal energy = mass x specific heat capacity x change in temperature.
Explanation: what it basically means is mass x heat x the change in temperature.
Explanation:
When water is heated up then its molecules move rapidly from one place to another. Hence, kinetic energy of the molecules tend to increase.
Also, K.E = 
where, T = temperature
Therefore, more is the increase in temperature more will be the mean molecular speed change in the water molecules.
As a result, mean molecular speed change increases with increase in temperature and vice-versa.
Where’s the rest of the question
1 atm is equal to 101.3 kpa.
therefore, to find the atm for 45.6kpa, divide 45.6 by 101.3 (and then multiply by 1 but that doesnt matter in this case).
giving 0.45 atm
