Answer:

Over time, the plant matter transforms from moist, low-carbon peat, to coal, All types of coal also contain sulfur, which, when burned, releases toxic air pollution. Sulfur All this coal comes from mines, which are either underground or run on diesel—a major source of air toxins, nitrogen oxide, and soot.

Suppose now that you wanted to determine the density of a small crystal to confirm that it is graphite. From the literature, you

kirza4 [7]

Answer:

The volume of first and second compound are 9.15 ml and 10.85 ml.

Explanation:

Given that,

Density of graphite = 2.25 g/cm³

Volume of mixture = 20.0 mL

Density of first compound = 1.492 g/ml

Density of second compound = 2.890 g/ml

Let the volume of first mixture = x

The volume of second mixture = (20-x)....(I)

We need to calculate the volume of first compound

Using formula of density of mixture

$\rho=\dfrac{V_{1}\rho_{1}+V_{2}\rho_{2}}{V_{1}+V_{2}}$

Where, $V_{1}$ = volume of first compound

$V_{2}$ = volume of second compound

$\rho_{1}$ =density of first compound

$\rho_{1}$ = density of first compound

Put the volume into the formula

$2.25=\dfrac{x\times1.492+(20-x)\times2.890}{x+20-x}$

$45=1.492x+57.8-2.890x$

$45-57.8=1.492x-2.890x$

$12.8=1.398x$

$x=\dfrac{12.8}{1.398}$

$x=9.15\ ml$

We need to calculate the volume of second compound

Using equation (I)

$V_{2}=20-x$

Put the value of x

$V_{2}=20-9.15$

$V_{2}=10.85\ ml$

Hence, The volume of first and second compound are 9.15 ml and 10.85 ml.

What do all acids produce when dissolved in water

RUDIKE [14]

Answer:

hydrogen ions

Explanation:

Acids are substances that when dissolved in water release hydrogen ions, H+(aq). Bases are substances that react with and neutralise acids, producing water. When dissolved, bases release hydroxide ions, OH-(aq) into solution. Water is the product of an acid and base reacting.
