Using bond-energy data, what is ΔrH for the following reaction? CH4(g) + 2I2(g) → CI4(g) + 2H2(g) Bond Bond Energy (kJ/mol) C-H 413 H-H 432 I-I 151 C-I 240

Consider the following function for getting the value of a cell from a CSV file. Lines 6 to 9 (highlighted by bold) have some bugs. Which of the following best describes the bugs in this program? # line 1  def cell(row_idx, col_name)：# line 2      col_idx ＝ csv_header.index(col_name)# line 3      val ＝ csv_data[row_idx][col_idx]# line 4      if val ＝＝ “”：# line 5          return None              # convert types based on column name, ensuring that the              # float and int values are appropriately converted# line 6      if col_name ＝＝ “price”：                                # line 7          int(val)# line 8      if col_name ＝＝ “latitude” or col_name ＝＝ “longitude”：# line 9          float(val)                                            # line 10     return val

Which one is NOT key component of Evaluation and Managment

Complete the function get_column to extract an entire column from data to a list. The formate of the dataset is: data ＝ [    [“male”，”18″，”student”]， # row 1    [“female”，”16″，”student”]， # row 2    [“male”，”22″，”TA”]  # row 3    # … more rows]header ＝ [“gender”，”age”，”role”] Since multiple dropdown makes it a little hard to read, we put the well-formatted version of code here. Select the correct code replacements in the below list of drop downs. def get_column(col_name):   col_idx ＝ **blank1**    data_column ＝ []    for row in data:       data_column.append(row[**blank2**])   return **blank3** get_column(“gender”) # sample invocation Select the best choice for: [blank1] [blank2] [blank3]
