I know for sure that it is francium
Meso−2,3−butanediol is the product of the top reaction
Taking into account the change of units, 21.8 in³ is equal to 0.357238 L.
<h3>Definition of rule of three</h3>
The rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied using the following formula, where a, b and c known data and x the variable to be calculated:
a ⇒ b
c ⇒ x
So: x= (c×b)÷ a
The direct rule of three is the rule applied in this case where there is a change of units.
<h3>in³ to liters</h3>
To perform in this case the conversion of units, you must first know that 1 in³ = 0.0163871 L. So, the rule of three can be used as follow: if 1 in³ is 0.0163871 L, 21.8 in³ equals how many L?
1 in³ ⇒ 0.0163871 L
21.8 in³ ⇒ x
So: x= (21.8 in³ ×0.0163871 L)÷ 1 in³
Solving:
<u><em>x= 0.357238 L</em></u>
In summary, 21.8 in³ is equal to 0.357238 L.

Answer:
= 1.0593 g
Explanation:
1.1% NaCl by mass, means;
1.1 g per 100 g = 0.011
Therefore; the amount of NaCl present in 93.6 g of the solution is;
= 0.011 × 96.3 g
<u>= 1.0593 g</u>
Answer:
the attractive forces keep the particles together tightly enough so that the particles do not move past each other.
Explanation:
In the solid the particles vibrate in place.
