I)Acetylene
II)2-Methyl-1-butanol
Explanation:
I)appears as a colorless gas with a faint garlic-like odor. Easily ignited and burns with a sooty flame. Gas is lighter than air.
Given-
Hydrogen ion concentration pH = 0.008
Now,
we know that pH + pOH = 14
pOH = 14-0.008
pOH = 13.992
Answer:
Explanation:
First we look generally at what makes K2SO4.
In one mole of K2SO4, there are 2 moles of the potassium ion (K+) and 1 mole of sulfate ion (SO4 2-).
Knowing that; in 1.75 moles of K2SO4, there must be 2 x 1.75moles of potassium ion (K+) and 1 x 1.75moles of Sulfate ion (SO4 2-)
This gives us 3.5moles of K+ and 1.75moles of SO4 2-
A converging lens made from a transparent plastic bottle filled with water is used to enable Pak Dollah read the newspaper.
<h3>What is long-sightedness?</h3>
Long-sightedness is an eye effect in which objects are not able to focus on the retina but behind the retina, therefore, near objects are not clearly seen except they are placed far away.
To correct long-sightedness, a suitable converging lens is used to bring the image to focus on the retina.
To construct a converging lens for Pak Dollah, the transparent plastic bottle is filled with water to serve as a converging lens and Pal Dollah will read through it.
Therefore, a converging lens made from a transparent plastic bottle filled with water is used to enable Pak Dollah read the newspaper.
