The molecular formula of hydrate : CaCl₂.6 H₂O

So there are 6 molecules of H₂O

<h3>Further explanation</h3>

Given

54.7g CaCl₂ and 53.64 g H₂O

Required

The number of molecules H₂O

Solution

mol CaCl₂ :

= mass : MW

= 54.7 : 111 g/mol

= 0.493

mol H₂O :

= 53.64 : 18 g/mol

= 2.98

mol ratio H₂O : CaCl₂ :

= 2.98/0.493 : 0.493/0.493

= 6 : 1

Which causes waves in the ocean to occur?​
galina1969 [7]

Answer:

Explanation:

C. energy being transferred from wind

Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.  The gravitational pull of the sun and moon on the earth also causes waves.

MA_775_DIABLO [31]

The most appropriate type of information for the government to use to make decisions is research reports containing scientific data.

<h3>What is pollution?</h3>

The term pollution has to do with the introduction of materials and energy that are harmful to the environment and also the fauna and flora.

1) The most appropriate type of information for the government to use to make decisions is research reports containing scientific data.

2) If the government committee learns about the side effects and decides the medication is not safe for public use, then the committee used an anecdote and did not use science to make the decision.

3) The type of research that might result in a law that restricts hunting of a particular species is research showing the species is endangered in other geographical areas

Activation process and importance of zymogen
ANEK [815]

Answer:

Zymogen ActivationZymogens are activated by snipping the bonds between two or more amino acids, rather like cutting a balloon string so that it floats away. When the bonds are cut, the enzyme changes its conformation, its 3-D structure, so that the active site is free and able to become active.

sing any data you can find in the ALEKS Data resource, calculate the equilibrium constant K at 25.0°C for the following reaction
prisoha [69]

Answer:

2.76 × 10⁻¹¹  

Explanation:

I don’t have access to the ALEKS Data resource, so I used a different source. The number may be different from yours.

1. Calculate the free energy of formation of CCl₄

                         C(s)+ 2Cl₂(g)→ CCl₄(g)

ΔG°/ mol·L⁻¹:       0         0         -65.3

ΔᵣG° = ΔG°f(products) - ΔG°f(reactants) = -65.3 kJ·mol⁻¹

2. Calculate K

\text{The relationship between $\Delta G^{\circ}$ and K  is}\\\Delta G^{\circ} = -RT \ln K

T = (25.0 + 273.15) K = 298.15 K

\begin{array}{rcl}-65 300 & = & -8.314 \times 298.15 \ln K \\65300& = & 2479 \ln K\\26.34 & = & \ln K\\K& = & e^{26.34}\\&= & \mathbf{2.76 \times 10}^{\mathbf{11}}\\\end{array}

On the enzyme hexokinase, ATP reacts with glucose to produce glucose 6-phosphate and ADP five orders of magnitude faster than AT
kvv77 [185]

Answer:

[The rate differential results from induced fit on the enzyme upon binding of glucose. This conformational change excludes water from gaining access to the -phosphate group on ATP, and brings the same group close to the OH group on carbon 6 of glucose]
