Answer:
The correct option is B. two oxygen atoms
Step-by-step explanation:
The molecular formula for carbon dioxide is given by :
Here, the alphabet C stands for Carbon and the alphabet O stands for Oxygen.
And the prefixes of each of these words represents the number of atoms present of the corresponding element in one molecule of carbon dioxide.
So, The prefix of the first word that is C is 1
⇒ One molecule of carbon dioxide contains one atom of Carbon.
The prefix of the second word that is O is 2
⇒ One molecule of carbon dioxide contains 2 atoms of Oxygen.
Therefore, The correct option is B. two oxygen atoms
Answer:
go to the left to -85 then go up to 52.
Step-by-step explanation:
x=-85
y=52
we know that
In parallelogram, the sum of consecutive angles are 180
so, consecutive angles are supplementary
And opposite angles are equal
so, we will check verify each options
option-A:
Since, consecutive angles are supplementary
so, this is FALSE
option-B:
Since, only opposite angles are equal or congruent
so, this is FALSE
option-C:
Since, consecutive angles are supplementary
so, this is TRUE
option-D:
Since, consecutive angles are supplementary
so, this is FALSE
Answer:
D is the answer
