Some acids are capable of drawing water out of an object. This process is called dehydration.
Hope this helped!
Answer:
in position and time graphs the slope of line indicates the velocity
Answer:
These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.
Explanation:
Answer:
The pressure in mmHg is 59.
Explanation:
Given data:
Pressure of air inside balloon = 0.78 atm
Pressure in mmHg = ?
Solution:
mmHg:
mmHg is referred as manometric unit of pressure. It is define as the pressure exerted by mercury column at height of one millimeter.
Symbol:
"mmHg"
Atmosphere (atm)
atm is unit of pressure. It is used as a standard unit. It is equal to the 101325 Pa.
1 atm = 760 mmHg
Inorder to convert the atm into mmHg we will multiply the given atm value with 760.
0.78 atm × 760 mmHg / 1 atm = 592.8 mmHg
59 mmHg or 59
Answer:
5.5 moles of sodium are produced
Explanation:
Given data:
Number of moles of hydrogen = 2.75 mol
Number of moles of Na produced = ?
Solution:
Chemical equation:
H₂ + 2NaCl → 2HCl + 2Na
Now we will compare the moles of hydrogen and sodium from balance chemical equation:
H₂ : Na
1 : 2
2.75 : 2/1×2.75 = 5.5 mol
Thus, 5.5 moles of sodium are produced.
