The characteristics of an Arrhenius acid was the acid donates H+ when it is in the aqueous solution, whether the solution is acid or base. If the solution is a acid, then be H+ builds up and increase its thing. The pH level for acid solution is the scale from 1-6. Even though the ph scale is lower than the base, the color also varies. It also applies to the base, too.
Answer:
CCl4
Explanation:
Because it is non polar and non polar substances are insoluble in water.
Answer: x=41
Sin, cos and tan are part of the trigonometric function. Sin is calculated from opposite/hypotenuse, while cos is calculated from adjacent/hypotenuse.
There is some formula that can be derived from the equation. One of them is sin (90-x)= cos x
If you use it, the calculation would be:
<span>sin 49° = cos x
</span><span>sin 49= sin (90-x)
49= 90-x
x= 90-49= 41</span>
