A bird flies at a speed of 15 m/s for 10 seconds, 1,200 m/min for 0.17 minute, and 2,500 cm/s for 5,000 milliseconds. What is th
DedPeter [7]

Answer:

Explanation:

average speed=distance travelled/time taken

distance=speed*time

15*10=150 m

1200 m/min=20 m/s

0.17 minute=10.2 seconds

20*10.2=204 m

2500 cm/s=25 m/s

5000 milliseconds=5 seconds

25*5=125 m

125+150+204=479 m

10.2+5+10=25.2

479/25.2=<u>19.0 </u>

1st Define Covalent bond and it's type
irakobra [83]

Answer:

  1. COVELENT BOND:-The chemical bond formed by the sharing of an electron pair between two atoms so that both the atoms get their octet complete is called covalent bond
  • SINGLE COVELENT BOND:-it is formed by sharing of one pair of electron between two atoms
  • DOUBLE COVELENT BOND:-it is formed by sharing of two pair of electron between two atoms
  • TRIPLE COVELENT BOND:- it us formed by sharing of three pair of electron beyween two atoms

2)Electron dot structures of carbon dioxide:-Oxygen atom contains 6 valence electrons which form 2 lone pairs. Since it is bonded to only one carbon atom, it must form a double bond. Carbon atom contains four valence electrons, resulting in zero lone pairs. Therefore, it is doubly bonded to each oxygen atom.

3))Sulfur has an atomic number is 16 with the

symbol as 'S'

  • The electronic configuration of sulfur is said to be 2,8,6
  • The valence electrons present in sulfur is 6.
  • Sulfur forms an octet structure by connecting 8 sulfur atoms with each other by the formation of single covalent bonds.
  • The sulfur molecule's chemical formula is S8.
  • Sulfur is usually used in the manufacture of sulphuric acid.

Consider the balanced chemical reaction when phosphorus and iodine react to produce phosphorus triodide: 2 P(s) + 3 I2(g) → 2 PI
melamori03 [73]

Answer:

Percent yield of PI3 = 95.4%

Explanation:

This is the reaction:

2P (s) + 3I2 (g) > 2PI3 (g)

Let's determine the moles of iodine that has reacted.

58.6 g / 253.8 g/mol = 0.231 mol

Ratio is 3:2. Let's make a rule of three to state the moles produced at 100 % yield reaction.

3 moles of I2 react to make 2 moles of PI3

0.231 moles of I2 would make (0.231 .2) / 3 = 0.154 moles of PI3

As we have produced 0.147 moles let's determine the percent yield.

(Yield produced / Theoretical yield) . 100 > (0.147 / 0.154) . 100 = 95.4%
