na2s + hcl _____ nacl + h2s Which of these would represent the coefficients needed to balance this equation? A) 1, 1, 1, 1 B) 1,
USPshnik [31]

Answer:

B) 1, 2, 2, 1

Step-by-step explanation:

In given equation:

Left side:                                Right Side:

  2 Na                                          1 Na

  1 S                                              1 S

  1 H                                             2 H

  1 Cl                                             1 Cl

To equal the number of Na and H atoms on both sides, HCl and NaCl will have a coefficient of 2 to balance the equation while Na₂S and H₂S will have a coefficient of 1.

1 Na₂S + 2 HCl ⇒ 2 NaCl + 1 H₂S

almond37 [142]

Answer:

Total distance = 5.754 km

Step-by-step explanation:

Red lines of the right triangle show the layout of the race course.

Total length of the race course = Perimeter of the triangle

Perimeter of the triangle = Sum of the measures of all three sides

                                         = 1.83 + 1.524 + 2.4

                                         = 5.754 km

Therefore, total distance of the race course is 5.754 km.
