Answer:

The 5.53 moles of virus in an oil tanker.

Explanation:

Given:

Mass of virus m = 9 \times 10^{-12} mg

Mass of oil M = 3 \times 10^{7} kg

From the formula of moles,

Moles of viruses is given by,

Mass of 1 oil tanker divide by mass of 1 mole of virus,

      = \frac{3 \times 10^{7} } {9 \times 10^{-12} \times 6.022 \times 10^{23} \times 10^{-6}   }

      = 5.53

Therefore, the 5.53 moles of virus in an oil tanker.

Heartburn is a form of indigestion felt as a burning sensation in the chest when stomach acid comes back up into the esophagus.
xenn [34]
The antacid is basic so it neutralizes acidity or lowers it. Then if it goes into the esophagus, it's not as strong and it doesn't hurt, and it also calms your stomach because the acidity in your stomach is also lower. Antacids are therefore taken by many people, especially as they grow older and things like heartburn become more common.
