A particular experiment requires 13.5 µl hydrochloric acid solution. if 250 ml hydrochloric acid solution is available, how many
ladessa [460]
The amount of HCl required for one experiment - 13.5 µl 
the volume in terms of L - 13.5 x 10⁻⁶ L
the volume of HCl available - 0.250 L 
since one experiment uses up - 13.5 x 10⁻⁶ L 
then number of experiments - 0.250 L / 13.5 x 10⁻⁶ L  = 1.8 x 10⁴ times 
the experiment can be carried out 18000 times

What type(s) of intermolecular forces are expected between ch3ch2ch2ch2oh molecules?
12345 [234]

Answer : Hydrogen-bonding, Dipole-dipole attraction and London-dispersion force.

Explanation :

The given molecule is CH_3CH_2CH_2CH_2OH.

Three types of inter-molecular forces are present in this molecule which are Hydrogen-bonding, Dipole-dipole attraction and London-dispersion force.

  • Hydrogen-bonding : when the partial positive end of hydrogen is bonded with the partial negative end of another molecule like, oxygen, nitrogen, etc.
  • Dipole-dipole attraction : When the partial positively charged part of the molecule is interact with the partial negatively charged part of the molecule. For example : In case of HCl.
  • London-dispersion force : This force is present in all type of molecule whether it is a polar or non-polar, ionic or covalent. For example : In case of Br-Br , F-F, etc

Hydrogen-bonding is present between the oxygen and hydrogen molecule.

Dipole-dipole forces is present between the carbon and oxygen molecule.

London-dispersion forces is present between the carbon and carbon molecule.

When assessing a client with suspected carbon monoxide poisoning, which finding would be least reliable?
Anna71 [15]

A cherry red complexion would be the least trustworthy result when evaluating a client who had carbon monoxide poisoning suspicions.

Carbon monoxide poisoning:

  • When present in sufficient quantity in the surrounding air, the odorless, colorless, and toxic gas known as carbon monoxide (CO) can result in rapid sickness and death. Using alternative fuels or electrical for warming, chilling, or cooking during power outages during situations like storms or winter storms can result in carbon monoxide(CO) buildup in a house, carport, or camper, which can harm the occupants and their pets.
  • It is never a good idea to use a generator, grill, camp stove, or any other appliance that burns fuel, kerosene, natural gas, or charcoal inside a house, basement, garage, camper, or even outside next to an apartment window or windows air conditioner.
  • Carbon monoxide poisoning can cause a variety of non-specific symptoms and indications. Migraine, vertigo, fatigue, vomiting, sickness, chest discomfort, and altered mental state are the most typical signs of CO poisoning.
