Answer:

  • First job out of college was in an industrial manufacturing setting.  Was told by plant engineer to walk around, get used to normal sounds.  He stressed anything "abnormal" is <u>a noise more so than a sound. </u> Report abnormalilies to supervisor immediately!!  So essentially sounds are giving us warnings something is abnormal.
  • Sounds also provide feedback.  Say you are performing an experiment, requires boiling water to sanitize.  Start the burner under a vessel, go on about other preparations.  Sound of water boiling will trigger setting a timer for how long to let it boil.
  • Get off work, pleasant music, nature sounds can help us decompress from a stressful day on the job.

Hope some of these give you impetus to think of other bullet points, sounds good to me.  !!

How many grams of nacl are in 250 g of a 15.0% (by weight) solution?
Gelneren [198K]

Answer: -

37.5 g of NaCl are in 250 g of a 15.0% (by weight) solution.

Explanation: -

Total mass = 250 g

Percentage of NaCl = 15.0 %

= \frac{Number of grams of NaCl present}{total mass}

Thus \frac{15}{100} = \frac{Number of grams of NaCl present}{250g}

Number of grams of NaCl present = \frac{15 x 250g}{100}

= 37.5 g

What atomic or hybrid orbitals make up the sigma bond between Cl and F in chlorine trifluoride, ClF3
Umnica [9.8K]

Answer:

sp³d¹ hybridization

Explanation:

Given Cl as central element with three F substrates ...

The VSEPR structure indicates 5 hybrid orbitals that contain 2 diamagnetic orbitals (non-bonded e⁻-pairs) and 3 paramagnetic orbitals (single, non-paired electron for covalent bonding with fluorine) giving a trigonal bypyrimidal parent with a T-shaped geometry.

Valence bond theory predicts the following during bonding:

Cl:[Ne]3s²3p²p²p¹3d⁰

=> [Ne]3s²p²p¹p¹d¹

=> [Ne]3(sp³d)²(sp³d)²(sp³d)¹(sp³d)¹(sp³d)¹

giving 3 ( [Cl](sp³d) - [F]2p¹ ) sigma bonds and 2 non-bonded pairs on Cl.

Note the following images:

Non-bonded electron pairs are in plane of parent geometry and Fluorides covalently bonded to central element Chloride forming the T-shaped geometry.

Suppose a phosphorus atom forms a bond with a fluorine atom. What type of bond must between these two elements?
Liula [17]

Answer:

Covalent bond

Explanation:

they will make a covalent bond with each other because both are non- metals and have a low electronegativity difference.
