The stomach normally contains around 50ml. of 0.125M HCI. Considering your answers to the previous two questions, how many mL of 0.125M NaOH would you need to fully neutralize a stomach after a person has taken an antacid medication? (This question has many possible answers, you just need to think it through and
type a number of mL in the blank below. Do NOT include units in your answer.)
Type your answer

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.

b is the correct answer

mark me brainliest and hope this

ok whats the question if not i cannot you i need question and need a thing to answer
