Vasoconstrictor Preservative is the solution that is added to the cartridge of local anesthetic that can trigger bronchospasms.

Contraction of the muscles that line the airways (bronchi) in your lungs is referred to as bronchospasms. This causes difficulty in breathing. Chest tightness, Wheezing, Shortness of breath, Difficulty breathing are some of the symptoms of bronchospasms.

Vasoconstrictor Preservative is an additive which is used in local anesthetic. It enhance the duration and quality of the local anesthetic and also decreases surgical blood loss. Local anesthetics without a vasoconstrictor should be used in patients with sulfite allergy.

If a mixture of quartz and bauxite contains 78% of quartz this means

There are 78gm of quartz in 100 gm of mixture/

There are 78gm of quartz for every 22 gm of bauxite.

There are 117gm of quartz for every 150gm of mixture.

If there is 78% of quartz in mixture of quartz and bauxite then

78% of quartz in 100% of mixture

If we suppose we have 100gm of mixture

Then ,

78% of 100 gm = 78gm

i.e. we have 78gm of quartz in mixture

100gm = quartz+ bauxite

100gm +78gm + bauxite

100- 78 = bauxite

Therefore bauxite = 22gm

Thus in 100 gm of mixture there is 78 gm of quartz and 22gm of bauxite.

If we suppose we have 150gm of mixture

Then ,

78% of 150 gm = 117gm

i.e. we have 117gm of quartz in mixture

150gm = quartz+ bauxite

150gm = 117gm + bauxite

150- 117 = bauxite

Therefore bauxite = 33gm

Thus in 150 gm of mixture there is 117gm of quartz and 33gm of bauxite.

Explanation:

The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.

The correct answer is 7596.5 Joules of heat energy is required to raise the temperature of 193 g of ethanol from 19°C to 35°C.

The amount of heat required is calculated as follows:

Q = mC∆T

m = mass =193g of ethanol

C = specific heat = 2.46J/g°C

∆T = T f-Ti = 35-19°C = 16°C

Q = 193g *2.46J/g°C *16°C

Q = 7596.5 J

We are interested in the value of Q, which is the quantity of heat. We would use the equation Q = mCΔT to do so.  mass and specific heat  are known; using the initial and final temperatures, the T can be calculated. Once we know three of the four quantities in the relevant equation, we can substitute and solve for Q. The amount of heat energy required to raise the temperature of a substance is referred to as its specific heat energy.

The elements Br₂ and ICl have the same number of electrons, yet Br₂ melts at -7.2°C and ICl melts at 27.2°C because Br₂ is a non-polar molecule with dispersion force as intermolecular interaction between them, whereas ICl is a polar molecule with dipole-dipole interactions and dispersion foces as intermolecular interaction.

ICl is with permanent dipole moment as the electronegativities of Cl and I are diffferent from each other.

The melting point of any compound rests on the intermolecular forces' stregth. More energy is required for stronger intermolecular forces so that it can overcome and have a higher melting point.

In Br₂ and ICl, the strength of dispersion force is similar because they have same number of electrons. But ICl have stronger dipole interactios too.

Therefore, strength of intermolecular forces is larger in ICl than in Br₂, so ICl have a high melting point of 27.2°C than Br₂ ( -7.2°C).
