Composting is a technique that allows biodegradable materials of urban, domestic and industrial origin to be degraded to form humus, a type of soil that is very fertile and extremely rich in micronutrients.
These biodegradable materials are materials of organic origin, such as food scraps, fruit peels, pieces of vegetables, among others. As the domestic environment generates a large amount of organic waste, composting in this environment is very favorable, and it can generate a very rich soil to be used in the garden, in vegetables, among other places.

Hope this helps :)

What takes pictures of clouds and storm systems from the exosphere

tamaranim1 [39]

The answer should be "Satellite." The satellite is placed in the exosphere which allows it to take pictures of the clouds from above, which is also how NASA gets most of it's pictures of the planet.

Hope this helps!

Taking into account the definition of density, the density of the sample is 0.5 $\frac{g}{mL}$ .

It is necessary yo know that density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density allows you to measure the amount of mass in a certain volume of a substance.

Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

$density=\frac{mass}{volume}$

In this case, you know:

mass= 6 g
volume= 12 mL

Then, replacing in the definition of density:

$density=\frac{6 g}{12 mL}$

Solving:

density= 0.5 $\frac{g}{mL}$

Finally, the density of the sample is 0.5 $\frac{g}{mL}$ .

Carbon and silicon are tetravalent but ge sn pb show di valency. Why

Anuta_ua [19.1K]

Answer:

Carbon and silicon both are tetravalent elements as compared to germanium, tin, and lead which are divalent.

That's because Ge, tin, and Pb show inert pair effect and has a greater nuclear effective charge on the 's' electrons due to poor shielding effect. .That's why these elements are not able to share their valence electrons while carbon and silicon does and show "catenation" which is the ability to form long chain molecules.
