Answer:
Here is an example of anchoring Bias
If I were to ask you where you think Apple’s stock will be in three months, how would you approach it? Many people would first say, “Okay, where’s the stock today?” Then, based on where the stock is today, they will make an assumption about where it’s going to be in three months. That’s a form of anchoring bias. We’re starting with a price today, and we’re building our sense of value based on that anchor.
Anchoring bias occurs when people rely too much on pre-existing information or the first information they find when making decisions. For example, if you first see a T-shirt that costs $1,200 – then see a second one that costs $100 – you're prone to see the second shirt as cheap.
Anchoring or focalism is a term used in psychology to describe the common human tendency to rely too heavily, or "anchor," on one trait or piece of information when making decisions.

19. Chemical properties can be used to
(1) differentiate between two compounds
(2) determine the temperature of a substance
(3) determine the density of a substance
(4) differentiate between two neutrons
Answer:differentiate between two compounds i think!
Explanation: taking a test!
Answer:(1) differentiate between two compounds
Explanation:
A Chemical property tells us the characteristics of a particular matter or substance after a chemical change. This property helps us to differentiate a compound from another or differentiate elements or substances. Examples of a Chemical property are acidity, reactivity and heat, etc .
For example to differentiate between Water H2O and Hydrogen peroxide, H202
Even though they are made up of oxygen and hydrogen. Hydrogen peroxide (H2O2), has more(1) oxygen than water (H2O).
Using Acidity as a chemical property to differentiate these substances
Water, H20 is amphoteric in nature ie having both acidic and basic properties, while H202 is a weak acid.

what kind of reaction?
Answer:
Nuclear fission
Explanation:
This reaction is called a nuclear fission reaction. In this reaction, a radioactive decay process occurs in which a heavy nucleus spontaneously disintegrates into two lighter nuclei and several neutrons, with the release of a large amount of energy.
The imbalance between the number of neutrons and protons is responsible for this spontaneous disintegration. Until a stable daughter cell forms, the reaction proceeds.Complete a write up about the elements in Ammonia and explain how the elements bounded to create the new substance.
Answer:
Explanation:
Ammonia consist of nitrogen and hydrogen.
Chemical equation:
N₂ + H₂ → NH₃
Balance chemical equation:
N₂ + 3H₂ → 2NH₃
We can see that nitrogen and hydrogen react with each other and from ammonia.
Nitrogen is present in group 5A. The atomic number of nitrogen is 7. Its atomic mass is 14 amu. It has 5 valence electron.
Electronic configuration:
N₇ = 1s² 2s² 2p³
we can see there are five electron in outer most shell. Thus, nitrogen needs three more electrons to complete the octet. When it combine with other atoms it gain three electron from them
While hydrogen is present in group 1A. It has one valence electron. In ammonia (NH₃) when nitrogen react with hydrogen it gain three electrons thus three atoms of hydrogen combine with one atom of ammonia because one hydrogen atom can share only one electron. Covalent bond is formed between nitrogen and hydrogen and new substance formed is called ammonia.
Annalise observes a streak of light in the sky and says she is seeing a shooting star. What is she most likely observing?
a falling star
an asteroid
a meteor
a dwarf planet
Answer: A Meteor
Explanation:
A streak of light in the sky and says she is seeing a shooting star. She's most likely observing is a meteor. Therefore, option C is correct.
What is a meteor ?A meteor is an object from space or a meteoroid that touches down on Earth. The air on the space rock creates drag that causes it to become incredibly heated as it falls toward Earth.
When the earth travels through cometary debris during its orbit around the Sun, meteor showers will result. Although the Earth's orbit around the Sun is nearly round, the majority of comets have very elliptical orbits.
A meteoroid becomes a meteor, or a streak of light in the sky, if it gets close enough to Earth and enters its atmosphere. These light striations are sometimes referred to as "shooting stars" due to their appearance. However, stars are not what meteors are.
Thus, option C is correct.

Is hydrogen a metal or a nonmetal? How many valence electrons does a hydrogen atom have?
Answer:
hydrogen is a non-metal, and has one valence electron.
Explanation:
Hope this helps!!
Hydrogen shows properties of both metals and nonmetals. However, hydrogen is placed with the alkali metals since it contains one valence electrons.
What is hydrogen ?Hydrogen is the first element in the periodic table. It has only one electron and it is the valence electron of hydrogen. Therefore, hydrogen is placed in the first group of periodic table.
Hydrogen needs one more electrons to become stable. The 17th group elements halogens also have a valency of one. Hence, hydrogen shows some chemical similarities with halogens also.
Mostly hydrogen forms covalent bonds like non-metals and in rare cases, hydrogen forms ionic bonds by donating its electron. Therefore, hydrogen is mostly considered as a non-metal.

Which example best demonstrates stewardship of the atmosphere
Incomplete question. However, I provided a specific example of stewardship of the atmosphere.
Explanation:
First, note that the term stewardship refers to the belief that humans are obligated to take care and look after our environment (which includes the atmosphere.
An example of this is: deciding to change our mode of transportation: What this entails is that we may decide to switch to riding a bicycle to places rather than going by car. By so doing you will be reducing the number of greenhouse gases emitted into the environment as bicycles do not emit harmful gases when used.
Suppose that a TLC plate is spotted with samples 1.0 cm above the bottom of the plate. Select the consequence of inserting the plate into a developing chamber containing a pool of developing solvent that is 1.2 cm deep
(a) The compounds in the samples will leach into the pool of developing solvent resulting in poor resolution.
(b)The pencil marks will dissolve into the developing solvent.
(c)The increased capillary action will cause the compounds to migrate up the plate more quickly.
(d)The increased depth of developing solvent will result in better resolution of the compounds in each sample.
Answer:
The compounds in the samples will leach into the pool of developing solvent resulting in poor resolution.
Explanation:
The aim of thin layer chromatography is the separation of a mixture. Usually, the stationary phase is spotted with the mixture. A mark is made with a pencil at the point to be spotted.
It is necessary to note that the solvent must be below the spot where the mixture is. This is because, if the solvent is above the spot of the mixture to be separated, the components of the mixture will dissolve away in the solvent resolution in poor separation. This is exactly what will happen when the sample is spotted at 1.0 cm above the bottom when the solvent is 1.2 cm above the bottom.

Answer: A
Explanation: Mortality means death. And it is a primary goal of Development Goals
Reducing child mortality, or rate of death, is one of the primary goals of the UN’s Millennium Development Goals and the correct option is option A.
What is Mortality?Mortality is defined as the state of the individual being dead. The mortality rate is the death rate of a population which is calculated on the basis of the deaths in the particular region.
Mortality as one of the components of demography is measured as mortality rate.
Mortality meaning provides the basis for mortality rate and its estimation. Mortality is the possibility of and susceptibility to death, and hence, the rate of mortality or the death rate is the measurement of the number of deaths that occur in a particular population, scaled to the size of that population per unit of time.
Therefore, Reducing child mortality, or rate of death, is one of the primary goals of the UN’s Millennium Development Goals and the correct option is option A.
