Explanation

Sepsis, chemosis, and proptosis following an ENT injection are indicative of a serious condition known as cavernous sinus thrombosis.

This occurs when a blood clot forms in the cavernous sinus

Typically due to an infection spreading from nearby structures such as the sinuses or the middle ear.

Explanation

 Cleavage is the tendency of a crystal to break along specific planes of weakness.

Copper, being a metal, has a unique atomic structure that doesn't exhibit distinct planes of weakness.

When stressed, it tends to deform rather than cleave, resulting in a jagged fracture. 

Explanation

Molar mass of sodium hydroxide (NaOH) = 23 (Na) + 16 (O) + 1 (H) = 40 g/mol

- For 2 moles: 40 g/mol × 2 = 80 grams

Explanation

 The maximum number of electrons in an atom is given by the formula:  

Total electrons = 2n²  

For n = 4:  

2(1² + 2² + 3² + 4²) = 2(1 + 4 + 9 + 16) = 2(30) = 60  

But this is a misunderstanding. Each shell holds:

- n=1: 2  

- n=2: 8  

- n=3: 18  

- n=4: 32  

So total = 2 + 8 + 18 + 32 = 60, but this is not per atom.  

If n = 4 is the maximum principal quantum number, then the 4th shell is being filled.  

The maximum number of electrons that can exist in the 4th shell is:  

2n² = 2(4)² = 32

Explanation

 In fructose, the functional group ketone is present on carbon number 2.

This is why fructose is classified as a ketohexose, a six-carbon sugar containing a ketone group. 

Explanation

Carbon monoxide is a toxic gas that interferes with the blood's ability to carry oxygen, making it harmful to humans.

It can cause symptoms like dizziness, nausea, and even death if inhaled in high concentrations.

Explanation

According to the Bronsted-Lowry theory, NH3 acts as a base because it can accept a proton (H^+).

According to the Lewis theory, NH3 is a base because it can donate a pair of electrons.

Explanation

CH3-CH2-CH3 is the molecular formula for propane, which is a saturated hydrocarbon (an alkane).
