Q = mCpΔT

Cp = 2.22 J/g°C
m = 150 g
ΔT = T(final) - T(initial) = -15°C - (-30°C) = +15°C

q = (150 g)(2.22 J/g°C)(15°C) = 4,995 J

Which of the following interactions are generally considered to be unfavorable? Group of answer choices a)Interaction between Ly

Anarel [89]

Answer:

d) Interaction between Arg and Lys side chains at a pH of 7, assuming standard pKa values for Arg and Lys.

Explanation:

Arginine and Lysine are basic amino acids. They play same role in various membrane proteins. They both have high aqueous values which give rise to high electrostatic interaction. The interaction is mainly in the cations of the side chains. They both are heterologous secreted proteins which plays role of metabolite.

We can also use the equation for enthalpy change for physical phase changes. Consider the phase change H2O(l) → H2O(g). Calculat

VLD [36.1K]

Answer: The value of enthalpy of the given reaction is 44.000 kJ/mol , that is energy is supplied to water to change into water vapors

Explanation:

$H_2O(l)\rightarrow H_2O(g),\Delta H_{rxn}=?$

Enthalpy of formation of water in liquid state, $\Delta H_{f,H_2O(l)}=-285.820 kJ/mol$

Enthalpy of formation of water in gaseous state, $\Delta H_{f,H_2O(g)}=-241.820 kJ/mol$

$\Delta H_{rxn}=\sum \Delta H_f \text{of products}-\sum \Delta H_f \text{of reactants}$

$\Delta H_{rxn}=(-241.820 kJ/mol)-(-285.820 kJ/mol)=44.000 kJ/mol$

The value of enthalpy of the given reaction is 44.000 kJ/mol, that is energy is supplied to water to change into water vapors.

Describe how cells are organized into larger and larger groups to help living things survive

mestny [16]

Cells are organized into tissues. Tissues carry out specific functions. Groups of tissues can then form organs that also have specific functions to carry out. Lastly groups of organs form organ systems that regulate many functions in a specific part of the body.

What does the 4 indicate in 1s22s22p4? 4th subshell 4 electrons 4th energy level

kupik [55]

Answer: The number 4 indicates 4 electrons.

Explanation: We are given an electronic configuration, which is:

$1s^22s^22p^4$

Here,

The letters denote the sub-shells of an element.

The numbers written before the letters which are 1, 2 and 2 represents the Principle Quantum Number and these represents the energy level of the sub-shells.

The number which are written in the superscripts which are 2, 2 and 4 denotes the electrons which are present in the sub-shell.

Hence, 4 indicates 4 electrons present in 2p sub-shell.
