Chemistry
2 answers:
SashulF [63]3 years ago

Answer:

Straight line.

Explanation:

On a graph a straight line shows a direct proportion relation.

The graph equation for a straight line is

y = mx + c

Where

m = slope

c= y-intercept

So here if we change "x" y will change linearly with the change.

B) a jagged line: it is a random relation between two properties

C) downward curved line: It is inverse relation with some log factor or square or other root.

D) upwardly curved line: it is direct relation with some log factor or square or other root.

An oxide of trivalent metal contains 32% of oxygen. Calculate the atomic mass of the metal.​
jekas [21]

The atomic mass of the metal.(M) = 51 g/mol

<h3>Further explanation</h3>

Given

32% of oxygen

Required

the atomic mass of the metal.​

Solution

An oxide of trivalent metal : M₂O₃(Ar O = 16 g/mol)

The molar mass of metal oxide = 2M+16.3=2M+48

32% of oxygen, then :

32% x 2M+48 = 48

0.32(2M+48)=48

0.64M+15.36=48

0.64M=32.64

M=51
