Answer:

Classify each statement as applying to ionic bonds, covalent bonds, or both types of bonds:

  • stay together in water  (Both bonds)
  • common in biomolecules, such as DNA and protein, lonic bonds Covalent bonds in living organisms  (Covalent bond)
  • attraction based on the number of electrons in the outermost shells of the elements involved  (Covalent bond)
  • oppositely charged ions are attracted to each other  (Ionic bond)
  • polar water molecules can pull them apart electrons are shared between atoms  (Ionic bond)
  • a strong interaction between atoms (Covalent bond)
  • form after one atom donates an electron to another atom (Ionic bond)

Explanation:

The covalent bond occurs between 2 atoms that join together sharing electrons at their last level .

The ionic bond occurs between 2 atoms fused by the permanent transfer of electrons.

What is water's density at 93 ∘C? Assume a constant coefficient of volume expansion. Express your answer with the appropriate un
Ganezh [65]

Answer:

982.5 kg/m³

Explanation:

When the temperature of a fluid increases, it dilates, and because of the variation of the volume, it's density will vary too. The density can be calculated by the expression:

ρ₁ = ρ₀/(1 + β*(t₁ - t₀))

Where ρ₁ is the final density, ρ₀ the initial density, β is the constant coefficient of volume expansion, t₁ the final temperature, and t₀ the initial temperature.

At t₀ = 4°C, the water desity is ρ₀ = 1,000 kg/m³. The value of the constant for water is β = 0.0002 m³/m³ °C, so, for t₁ = 93°C

ρ₁ = 1,000/(1 + 0.0002*(93 - 4))

ρ₁ = 1,000/(1+ 0.0178)

ρ₁ = 982.5 kg/m³

A sample of argon gas at 55°C is under 845 mm Hg pressure. What will the new temperature be if the pressure is raised to 1050 mm
Maurinko [17]

Answer:

The final temperature at 1050 mmHg is 134.57 ^{\circ}C or 407.57 Kelvin.

Explanation:

Initial temperature = T = 55^{\circ}C = 328 K

Initial pressure = P = 845 mmHg

Assuming final  to be temperature to be T' Kelvin

Final Pressure = P' = 1050 mmHg  

The final temperature is obtained by following relation at constant volume

\displaystyle \frac{P}{P'}=\displaystyle \frac{T}{T'} \\ \displaystyle \frac{845 \textrm{ mmHg}}{1050 \textrm{ mmHg}} = \displaystyle \frac{328 \textrm{ K}}{T'} \\T' = 407.57 \textrm{ Kelvin}

The final temperature is 407.57 K

A jug contains 2L of milk. Calculate the volume of the milk in m3
stepan [7]

Answer: 0.002 m³

Explanation:

We can use our unit conversions to find the volume in m³.

2L*\frac{1m^3}{1000L} =0.002m^3
