Answer:
a) 0.000765kg
b) 1340mg
c) 0.0342g
Explanation:
a) 1000g = 1kg
0.765g= 0.765/ 1000
= 0.000765g
b) 1g = 1000mg
1.34g = 1.34 × 1000
= 1340mg
c) 1000mg = 1g
34.2mg = 34.2/1000
= 0.0342g

Which of the situations below describes an ethical dilemma related to food
engineering?
A. Educational seminars should be conducted to help consumers
grow their own crops.
B. Production plants should be located close to consumers so
distribution runs efficiently.
C. Pesticides protect our crops, but some European countries have
linked them to thyroid disorders.
D. Preservatives must be used so that food can reach the consumer
before spoiling
Answer:
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.what is atomic mass

what is biogas, biomass and biodigester
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.
How does density affect the water cycle
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.

A neutral atom of sulfur becomes an ion with a negative two charge by?
Answer:
The valence shell (the 3s and 3p sublevels) contains six electrons, but it needs eight to become stable. Think of the octet rule. Therefore a sulfur atom will gain two electrons to form the sulfide anion with a charge of 2− , with the symbol S2− .
A carpenter uses sandpaper on a piece of wood. Before, the wood felt rough. After, the wood felt smooth. Did the friction between the hand and the wood increase or decrease after using the sandpaper? Describe what the sandpaper did to the wood to make it smoother.
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!

CsF + XeF6 => CsXeF7
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

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
The ground state configuration : 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p¹
Further explanationElectrons 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
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?
Answer:
Explanation:
Convert mass in gms .. 987 gms
Density = mass/ volume
= 987/4.52 x102
= 2.18 g/mL
What is the kinetic energy of a 100 kg bear running at 3 m/s
Answer:
The answer is 450 JExplanation:
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 JHope this helps you
