Covalent bond is a type of chemical bond which is formed as a result of sharing of electron pairs among the elements that are involved. The structure of the covalent bond is affected by the electronegativity of the elements involved. The molecules joined by covalent bond range in size from very small to very large polymers. There are different types of structures for covalent substances, these include: macromolecular substances, molecular substances and giant covalent structures. Strong bonds hold individual molecules together but there are negligible forces of attraction among them.
Answer:
1. 10.37114 psi
2. 71.5178 KPa
3. 71517.8 Pa
4. 536.56 mmHg.
5. 21.12352 inHg
Explanation:
From the question given,
Pressure = 0.706 atm
The pressure in other units of measurement is obtained as follow:
1. Pressure in Psi
1 atm = 14.69 psi
Therefore, 0.706 atm = 0.706 x 14.69 = 10.37 psi
2. Pressure in KPa
1 atm = 101.3 kPa
Therefore, 0.706 atm = 0.706 x 101.3 = 71.5178 KPa
3. Pressure in Pa
1 atm = 1.013x10^5 Pa
Therefore, 0.706 atm = 0.706 x 1.013x10^5 = 71517.8 Pa
4. Pressure in mmHg
1 atm = 760mmHg
Therefore, 0.706 atm = 0.706 x 760 = 536.56 mmHg
5. Pressure in inHg
1 atm = 29.92 inHg
Therefore, 0.706 atm = 0.706 x 29.92 = 21.12352 inHg
The solution is buffered with a weak acid and it's conjugate base. Since NaOH is a base, you can use a weak acid as it's buffer.
Answer: liquid water
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
is positive when randomness increases and is negative when randomness decreases.
Gases have more entropy than liquids and liquids have more entropy than solids due to movement of particles.
Thus liquid water will have more entropy than crushed ice.
