Which element has the
greatest number of valence electrons available for bonding?
O selenium
Oboron
O calcium
O chlorine

Answers

Answer 1
The element Chlorine has the greatest number of valence electrons for bonding. This is because selenium has 6 valence electrons, boron has 3 valence electrons, calcium has 2 valence electrons, and chlorine has 7 valence electrons. Therefore we can see that since 7 is the greatest number chlorine has the greatest number of valence electrons.

what is biogas, biomass and biodigester​

Answers

Answer:

Biogas is a type of biofuel that is naturally produced from the decomposition of organic waste. When organic matter, such as food scraps and animal waste, break down in an anaerobic environment (an environment absent of oxygen) they release a blend of gases, primarily methane and carbon dioxide.

Explanation:

Biomass is renewable organic material that comes from plants and animals. ... Biomass contains stored chemical energy from the sun. Plants produce biomass through photosynthesis. Biomass can be burned directly for heat or converted to renewable liquid and gaseous fuels through various processes.biodigester is like a mechanical stomach. It is fed with organic material, which is broken down (decomposed) by micro-organisms (bacteria) is an oxygen-free (anaerobic) environment to produce a renewable energy called biogas (methane and carbon dioxide) and other material that is mainly used as fertilizer.

Explanation:

Biogas is a type of biofuel that is naturally produced from the decomposition of organic waste.

Biomass is plant or animal material used for energy production, or in various industrial processes as raw substance for a range of products.

A Biodigester simply means a tank which digests organic material biologically. In this sense, the FilterPod is a biodigester. However, many people think of a biodigester as a tank which digests, anaerobically, without air, organic material and produces methane gas for cooking, lighting and heating ect.

What is the kinetic energy of a 100 kg bear running at 3 m/s

Answers

Answer:

The answer is 450 J

Explanation:

The kinetic energy of a body can be found by using the formula

[tex]KE = \frac{1}{2} m {v}^{2} \\ [/tex]

where

m is the mass

v is the velocity

From the question

m = 100 kg

v = 3 m/s

We have

[tex]KE = \frac{1}{2} \times 100 \times {3}^{2} \\ = 50 \times 9[/tex]

We have the final answer as

450 J

If the density of a substance is 2.18 g/mL, how would you find the density given that the mass is 0.987 kg and the volume is 4.52 x 102 mL?

Answers

Answer:

Explanation:

Convert mass in gms .. 987 gms

Density = mass/ volume

= 987/4.52 x102

= 2.18 g/mL

POSSIE Gallium (Ga) is a soft, silvery metal used primarily in electronic circuits, semiconductors, and light-emitting diodes (LEDs). It is also useful in high-temperature thermometers, barometers, pharmaceuticals, and nuclear medicine tests. Which electron configuration represents the electrons in an atom of gallium at ground state? O1s 2s22p63s23p64524d104p? O 182 2s22p63s23p64s24p1 o 1s 2s22p63s23p64823d104p? O 182 2s22p63s23p64s3​

Answers

The ground state configuration : 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p¹

Further explanation

Electrons can move the shell up or down by releasing energy or absorbing energy  

It can be concluded that there are 2 conditions:  

Ground-state is the state of electrons filling the shell with the lowest energy levels.  

Excited-state is the state of electrons which occupies a higher energy level  

The state of excited electrons can be seen from the presence of electrons which do not fill the shell completely but fill the shell afterward  

Gallium (Ga) is a metal located in group 13, p-block and  period 4

Atomic number : 31

If we look at the options:

options 1,2 and 3 do not conform to Aufbau principle(Electrons occupy orbitals of the lowest energy level  ), because 3d orbitals do not exist and the number of electrons is also not 31

So that the most appropriate electron configuration is:

1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p¹ = 31 electrons

or we can write : [Ar] 4s² 3d¹⁰ 4p¹

CsF + XeF6 => CsXeF7​

Answers

Answer:

Mass of CsXeF₇  = 99.3 g

Explanation:

Given data:

Mass of CsF = 37.8 g

Mass of CsXeF₇ produced = ?

Solution:

Balance chemical equation:

CsF + XeF₆   →    CsXeF₇

Number of moles of CsF:

Number of moles = mass/molar mass

Number of moles = 37.8 g/ 152 g/mol

Number of moles = 0.25 mol

Now we will compare the moles of CsF with CsXeF₇  from balance chemical equation:      

                   CsF             :         CsXeF₇

                    1                 :             1

                 0.25             :           0.25

Mass of CsXeF₇ :

Mass = number of moles × molar mass

Number of moles = 0.25 mol × 397.2 g/mol

Mass = 99.3 g

Answers

Answer:

Friction between the hand and the wood decreased.

Explanation:

The texture of the wood went from rough → smooth! This means friction between the hand and the wood was notably decreased.

According to this prompt, the carpenter used sandpaper against the wood. Sandpaper just so happens to be a very abrasive substance. The sandpaper polished and leveled out the wood which wore all the jutting bits away.- overall, making it much smoother and more pleasant to touch!

C. Pesticides protect our crops, but some European countries have

linked them to thyroid disorders.

Explanation:

Researches involving human or sometimes animals are subject to critical decision making.

They can easily trespass on the fundamental rights of people and some other issues.

The use of pesticides on a crop which can lead to thyroid disorder is an ethical dilemma. In this case, the pesticide helps to prevent crop loss due to the invasion of pests. This will boost food production and ensure food is availableLikewise, the application of the pesticide causes thyroid issues. This is an ethical dilemma issue.

How does density affect the water cycle

Answers

Gravity pulls denser air and water downward, forcing less dense air and water to move upward. The warm water near the surface of the ocean heats up with sunlight and evaporates, keeping the water cycle in motion.

Have a nice day :)

Explanation:

Biological in the ocean is affected by the water cycle via the Mixed Layer Depth and Run off from land. Salinity and temperature determine the density of ocean water, and density influences the circulation. E-P determines surface salinity of the ocean, which helps determine the stability of the water column.
