<em>But I do know...</em>
It's because new strains of the virus are constantly appearing and evolving, so the vaccine must change along with them.
Answer:
C3H8 + 5O2 => 3CO2 + 4H2O
Explanation:
Hydrocarbon combustion is the reaction between a hydrocarbon and O2 producing CO2 and water.
C3H8 + O2 => CO2 + H2O
First we balance the C and H.
C3H8 + O2 => 3CO2 + 4H2O
Now we balance O for the answer!
C3H8 + 5O2 => 3CO2 + 4H2O
The correct answer will be:
<span>carbon-14 and hydrogen-3 would most likely decay because their neutrons and protons are not equal.
Due to atoms tend to decay when it has excess of either protons or neutrons

Explanation:
The question is:
<h2>What is the distance of the object from the mirror?</h2>
To answer this question, you must learn that, for plane mirrors, the distance of the object from the mirror is equal to the distance of the image formed behind the mirror.
For instance if you stand 1 meter away from a mirror (a plane one) the position of the image of you will be 1 meter behind the mirror.
Here, the initial distance between the image and the object is 40 cm. Then, the distance between the image and the miror is 20 cm, such as it is the distance between the object and the mirror.
That the distance of the object is reduced by 9.2 cm, must be understood as that the object was placed 9.2 cm closer to the mirror.
Then, the new distance of the object from the mirror is 20 cm - 9.2 cm = 10.8 cm. ← answer
