Answer:
HCO₂
Explanation:
From the information given:
The mass of the elements are:
Carbon C = 26.7 g; Hydrogen H = 2.24 g Oxygen O = 71.1 g
To determine the empirical formula;
First thing is to find the numbers of moles of each atom.
For Carbon:
For Hydrogen:
For Oxygen:
Now; we use the smallest no of moles to divide the respective moles from above.
For carbon:
For Hydrogen:
For Oxygen:
Thus, the empirical formula is HCO₂
Explanation:
While atomic radii DECREASE across a Period, a row of the Period Table, from left to right as we face the Table, atomic radii INCREASE down a Group, a column of the Periodic Table, due to the shielding of the valence electrons by the closed valence shell(s) that intervenes between the nucleus and the valence, outermost electrons.
Asteroids are rocky space debris that are formed from interspacial collisions and collection of dusty particles. our solar system has an enormous asteroid belt between Mars and Jupiter.
Jupiter also has more local asteroids that are locked to its gravitational pull.
Not to be confused with a comet or meteor.
Answer:
They are the same types of atoms.
Explanation:
C.
Matter can not be created or destroyed, so in a closed system it stays constant
