First from the data given we are able to determine the empirical formula of the product. To do that we use the following algorithm:
1) Divide each percentage at the atomic mass of each element:
O 51.3 / 16 = 3.21
C 42.2 / 12 = 3.52
H 6.5 / 1 = 6.5
2) Now we divide the result to the lowest number, which is 3.21:
O 3.21 /3.21 = 1
C 3.52 /3.21 = 1.1 ≈ 1
H 6.5/3.21 = 2
So the empirical formula of the unknown compounds is:
CH₂O
We can conclude that the compound contains carbon, hydrogen and oxygen in the ratio given by the empirical formula:
C : H : O = 1 : 2 : 1
Answer:
C: 4
Explanation:
In every single covalent bond, each atom shares one electron. 1 + 1 = 2. A double bond is just two bonds so, 2 x 2 = 4.
Answer:
the system has infinitely many solutions.
Explanation:
The system is 2x + y = 1 and 4x + 2y = 2. Solutions to a system are the intersection points. Since these two lines are the same line they intersect everywhere. There are infinitely many solutions.
