Answer : The volume of 
produced will be, 0.8 liters.
Explanation : Given,
Volume of 
= 1.2 L
At STP, 1 mole of substance contains 22.4 L volume of substance.
The given balanced chemical reaction is:
From the balanced chemical reaction we conclude that,
As, 
volume of produced 
volume of
So, 
volume of produced 
volume of
Therefore, the volume of produced will be, 0.8 liters.
Explanation:
<h2>Radium(Ra)=> </h2>
atomic number=88
<h2>BERYLLIUM (Be)=></h2>
atomic number =4
why is Ra larger than Be
<h3>1. since the atomic number of Ra is greater than Be, the number of electrons is more, which means there are more number of shells present in Ra than Be. </h3><h2>(atomic Radius)</h2>
<h2>2. the more the valence electron (excluding fully filled ones) the less is the nuclear attraction force</h2><h3>since Ra has more valence electron in its outermost shell, the nuclear attraction force is less which means that Ra 's size is greater than Be.</h3>
hope it helps:)
Full moon
A lunar eclipse can occur only at full moon. A total lunar eclipse can happen only when the sun, Earth and moon are perfectly lined up — anything less than perfection creates a partial lunar eclipse or no eclipse at all.
Answer:
the heat energy is transformed to any kind of energy depending on what it's meant to be transformed to.
remember it cannot be destroyed so it's definitely transformed to some kinda energy
