Answer:
Empirical formula= COOH
Step-by-step explanation:
Molecular mass of the elements
Carbon= 12
Oxygen= 16
Hydrogen= 1
We divide the elements each with their molecular formula
Carbon= 2.4/12
Carbon= 0.2
Oxygen= 6.4/16
Oxygen= 0.4
Hydrogen= 0.2/1
Hydrogen= 0.2
Now we divide with the smallest result which is 0.2
Carbon= 0.2/0.2
Carbon = 1
Oxygen= 0.4/0.2
Oxygen= 2
Hydrogen= 0.2/0.2
Hydrogen= 1
So we have
Carbon 1, oxygen 2, hydrogen 1
Empirical formula= COOH
35 + 35 =70 i guess its saying to add up the months so i guess its saying whats 35 + 35 =70 thats what i got

Find out the statement true regarding the diagram given in the question
Answer
the statement is true regarding the diagram is
m∠WXY + m∠YXZ = 180°
REASON
As shown in the diagram
∠WXY and ∠ YXZ are supplementary angles.
Supplementary angle definition
Two Angles are said to be Supplementary when there sum is equal to 180 °.
thus we get
m∠WXY + m ∠YXZ = 180 °
Therefore the m∠WXY + m∠YXZ = 180° is the true statement.
