Franco was told that he had mycarditis. He went home and researched the disease, and he determined that he had
Reil [10]

Answer:

Myocarditis = C) Inflammation of the muscular wall of the heart.

Explanation:

Myocarditis is a condition usually caused by a virus.

It causes inflammation within the heart, generally along the muscular wall and within the middle layers.

It's definitely not a great condition. It's possible it could weaken his heart's ability to pump properly, which in turn could effect organs and cause organ failure. It'd lead to intense bouts of pain constantly, swelling, problems breathing, or even heart failure.

Feel bad for Franco.

Methyl orange (HMO) is an acid-base indicator. Its two forms in solution are HMO (red) and MO- (yellow). When HMO is added to di
Anna007 [38]

Answer:add acid

Explanation:

Methyl orange is red in acid and yellow in base. When added to distilled water and the colour turns yellow, it means it is in its anion form. The equilibrium can be shifted towards the acid form (HMO) by adding acid. The acid will protonate the indicator shifting the position of equilibrium towards the acid side and the solution turns red.

What is the molarity of a solution composed
Neporo4naja [7]

Answer:

0.0845 M

Explanation:

First we <u>convert 4.27 grams of potassium iodide into moles</u>, using its <em>molar mass</em>:

  • Molar Mass of KI = 166 g/mol
  • 4.27 g ÷ 166 g/mol = 0.0257 mol

Now we <u>calculate the molarity of the solution</u>, using <em>the number of moles and the given volume</em>:

  • Molarity = moles / liters
  • Molarity = 0.0257 mol / 0.304 L = 0.0845 M
