We often say ‘it is freezing ‘ when the temperature is cold outside. Explain why this is not an accurate statement.
ratelena [41]
The saying it's freezing outside just means it feels very cold. It's not accurate because the temperature doesn't actually cause you to psychically freeze.

Answer:

K = 9.620 × 10⁻⁶

Explanation:

From the given information:

Temperature T= 6° C

= (273 + 6)K

= 279 K

The correct and well presentation of the reactions are:

1. Luciferin + O_2     ⇆     oxyluciferin + light   ΔG₁°

2. ATP                     ⇄   AMP + PP_i                  ΔG₂°  = -31.6 kJ/mol

The overall  ΔG° = -4.80 kJ/mol

Let's first determine the ΔG₁° for the equation (1)

ΔG° = ΔG₁° + ΔG₂°

- ΔG₁° = - ΔG° + ΔG₂°

ΔG₁° = ΔG° - ΔG₂°

ΔG₁° = ( -4.80 - (-31.6) ) kJ/mol

ΔG₁° = 26.8 kJ/mol

Using the formula:

ΔG° = -RTIn K

In \  K =\dfrac{-\Delta G^0}{RT} \\ \\ log \ K = -\dfrac{\Delta G^0}{2.303RT}

log \ K = -\dfrac{\Delta G_1^0}{2.303RT} \\ \\ log \ K = -\dfrac{26.8 \times 10^3 \ J/mol}{2.303\times 8.314 \ J/mol/K \times 279 \ K} \\ \\ log \  K =- 5.017

K = antilog (-5.017)

K = 9.620 × 10⁻⁶

If you could repeat the lab and make it better, what would you do differently and why?
lions [1.4K]

Answer:

The advise I will offer the next scientist about how the laboratorycan beimproved include the following 

Calibration of instruments: Instruments which are used in the laboratory should be calibrated so as to reduce errors and inaccuracy during experiments.

Proper labeling of Samples : This helps to give the scientists an idea of where to find samples and to prevent making mistakes in picking the wrong one. This helps to save time and resources in the lab.

Adequate cleaning and waste disposal: Cleaning of the lab and disposal of the wastes helps to eliminate contamination of samples.
