Explanation:

Rainwater harvesting is collecting the run-off from a structure or other impervious surface in order to store it for later use. Traditionally, this involves harvesting the rain from a roof. The rain will collect in gutters that channel the water into downspouts and then into some sort of storage vessel.

Answer:

Rainwater harvesting is the accumulation and storage of rainwater for reuse on-site, rather than allowing it to run off. Rainwater can be collected from rivers or roofs, and in many places, the water collected is redirected to a deep pit (well, shaft, or borehole), a reservoir with percolation, or collected from dew or fog with nets or other tools. Its uses include water for gardens, livestock, irrigation, domestic use with proper treatment, indoor heating for houses, etc. The harvested water can also be used as drinking water, longer-term storage, and for other purposes such as groundwater recharge.

Rainwater harvesting is one of the simplest and oldest methods of self-supply of water for households usually financed by the user.

The correct answer should be
carbon monoxide will be produced

Combustions release heat, they don't absorb it. Oxygen is not necessary as other gasses can also do it, while chlorine is not necessary.

3) In 5 electron group molecules, what is the difference between axial and equatorial positions? Which groups are removed as lon

shusha [124]

The axial positions the bond angle is 120 degrees and in equatorial positions the bond angle is 90 degrees.

Functional groups on central atom gets reduce if lone pairs are added.

Explanation:

The number of lone pairs and base pairs of electrons tells the geometry of the molecule.

VSEPR Theory helps to know the lone pairs and bond pair electrons on the centre atom of the molecule.

Example of molecule containing 5 electron pairs can have four bond pairs and 1 lone pair.

eg: Cl $F_{3}$

the repulsion is shown as

lp-lp> lp-bp>bp-bp

These are in equatorial position because of the repulsion of lone pairs.

It can have 2 lone pairs and 3 bond pairs. eg. Xe $F_{2}$

Lone pairs in this is also in equatorial position as

lp-lp> lp-bp> bp-bp

In axial positions the bond angle is 120 degrees

in equatorial positions the bond angle is 90 degrees, due to the repulsion in lone pair of electrons.

If 1 lone pair is there it can be replaced by bonding with hydrogen.

If 2 lone pairs are there then bonding with oxygen is there. The covalent bond is formed.

Can someone please help me with this I’ll mark brainliest, in the boxes below label what level of organization might look like?

ELEN [110]

Answer:

Vascular tissue transports water, minerals, and sugars to different parts of the plant. Vascular tissue is made of two specialized conducting tissues: xylem and phloem. Xylem tissue transports water and nutrients from the roots to different parts of the plant, and also plays a role in structural support in the stem.

When the volume changes from 63.5 mL to 69.2 mL, what is the final pressure if the initial pressure was 735 mmHg pressure?

Trava [24]

To solve this problem we use Boyle's law to correlate the varying volume and pressure at constant temperature. Assuming ideal gas law, we use the equation P1/V1= P2/V2. Substituting, 735 mm Hg/ P2= 63.5 ml/69.2 ml. P2 is equivalent thus to 800.97 mm Hg.

Explain the statement "atomic weight or molecular weight is a relative weight"

ratelena [41]

the relative mass of an atom or molecule is hence considered by considering a mass of a light atom and relating the mass of other atoms or molecules to it
