Answer:
No he will not have hard boiled eggs for breakfast
Explanation:
The temperature required to boil the eggs is about 100⁰C. Unfortunately, at the height of the base camp (5,300 meters), water boils at 82⁰C.
This implies that the egg will not become cooked as at the time when the water begins to boil.
Since the eggs can only become hard boiled at 100⁰C and the temperature at which water boils at 5300 meters is less than that(82⁰C), the eggs can not become hard boiled.
what is the environmental effect of 3NaCl
Answer:
Sodium and chloride ions separate when salts are dissolved in water. The dissolved sodium and chloride ions, in high concentrations, can displace other mineral nutrients in the soil. Plants then absorb the chlorine and sodium instead of needed plant nutrients such as potassium and phosphorus, leading to deficiencies.

What conclusion can you draw about the ability of metals to hold on to and attract electrons, as
compared to nonmetals?
Answer:
Metals react by losing electrons. So, there is high reactivity due to lower attraction. Non-metals react by gaining electrons. So, there is high reactivity due to higher attraction.
Explanation:
Metals react by losing electrons. So, there is high reactivity due to lower attraction. Non-metals react by gaining electrons. So, there is high reactivity due to higher attraction. Also, electrons lost by metals transfer to the nonmetals. It is easier for the metals to lose their valance electrons and form cations rather than gaining electrons.
Metals do not hold on to or attract electrons while nonmetals hold on to or attract electrons.
In the periodic table, metals are found towards the left hand side of the table while nonmetals are found towards the right hand side of the table.
Electron affinity of elements increase from left to right across the period. Electron affinity refers to the ability of elements to attract or hold electrons. This ability increase steadily across the period.
Usually, the electron affinity values of nonmetals are very high showing that they easily hold on to and attract electrons while the electron affinity values of metals is very low showing that they do not easily hold on to and attract electrons.

Is the following equation balanced? Why or why not?
2H2 +02 → 2H,0
Answer:
Yes
Explanation:
It is balanced because On both sides there are 4 hydrogen atoms and 2 oxygen atoms, or in this case, 2 molecular hydrogens and 1 molecular oxygen, which made hydric acid, aka dihydrogen monoxide, or universally, as water.
how does the structure of atoms (i.e. protons, neutron, and electrons) affect the electric charge of an object or substance.
Electrons contribute greatly to the atom's charge, as each electron has a negative charge equal to the positive charge of a proton. Scientists define these charges as “+1” and “-1. ” In an uncharged, neutral atom, the number of electrons orbiting the nucleus is equal to the number of protons inside the nucleus.:

Which of the following are NOT SAFE things to do, as we might get an electric shock?
1) Touching the switch of a geyser with dry hand.
2) Standing on a wooden stool to check a plug point.
3) Poking a metal rod into an electrical socket.
4) Touching the water in which an immersion heater is kept.
1 is the answer cuz why not
Answer:Poking a metal rod into an electrical socket.
Explanation:
It is because metal rod can conduct electricity easily. So while poking, the metal rod will conduct electricity and you will get an electrical shock.

Explanation:
What are water and carbon dioxide in the cellular respiration reaction? They are reactants because they are present before the reaction. They are reactants because they are present after the reaction. They are products because they are present before the reaction. They are products because they are present after the reaction.
Answer:
They are products because they are present after the reaction.
Explanation:
A chemical reaction refers to any interaction between two or more chemical species that leads to the formation of new chemical species. The species that interacted with each other are called reactants. They were present before the reaction commenced. The species that were formed after the interaction are called products. They only appear after the reaction.
In cellular respiration, carbon dioxide and water appear after the chemical reactions that take place, hence they are products.
Answer:
They are products because they are present after the reaction.
Explanation:
The volume of a sample of gas measured at 27 °C is 10.0 dm . What is the temperature when the volume is reduced to 9.0 dm at the same pressure?
The second temperature of the sample of gas is 24.3°C
The calculation can be done as follows
T1= 27 °c
T2= ?
V1= 10 dm
V2= 9 dm
V1/T1= V2/T2
10/27= 9/T2
Cross multiply
10 ×T2= 9 × 27
T2= 9 × 27/10
= 243/10
= 24.3 °C
Hence the second temperature is 24.3°C

Some power plants burn coal to produce electricity. The energy released from coal being burned is used to change water into steam. The steam spins turbines of large generators that produce electricity. Which energy transformations occur when coal is used to produce electricity?
Answer:
Steam thus released transforms heat energy from burning coal into mechanical energy that in turn spins the turbine engine. The kinetic energy of the spinning turbine does work in a generator and then the generator that turns this work into electric energy.

Iron (Fe) is an effective conductor of heat and electricity. Which other element is MOST likely to
have similar conductivities?
(A) potassium (K)
(B) nickel (Ni)
(C)bromine (Br)
(D) krypton (Kr)
Answer:
B
Explanation:
Conductors are able to conduct electricity and temperature. Most of the metals, metalloids and alloys are conducting. Like iron (Fe) nickel is a good conductor.
What is conductivity?Conductivity is a physical property of substances indicates the ability to conduct heat and electricity. Substances like metals are conductors because of the presence of free electrons in them.
The flow of free electrons in solids make the substance conducting. Substances which does not conduct is called insulators and those which conduct partially is called semiconductors.
Gases and liquids with fewer electrons are not conducting. Thus bromine is not a conductor. Krypton is a noble gas and is not conducting, potassium does not conduct electricity but it is thermally conducting.
Hence nickel (Ni) is the element having similar conductivity of iron. Thus option B is correct.

HELP!! Worth 16 points
Answer:
I believe the boiling point is 102 degrees Celsius and the freezing point is -2 degrees Celsius (so C).
Explanation:
Gas has a higher entropy than liquid, who has a higher entropy than solid. If a solid melts or a liquid vaporizes, the entropy increases. If a solute is present, it also contributes to the entropy of the mixture. The liquid already has a higher entropy (molecule randomness or disorder) than the pure liquid, so there's less likelihood of forming gas. This, therefore, means that it has a higher boiling point. This randomness also opposes freezing. A lower temperature has to reached before balance between solid and solution reached. So, the freezing point is lower.
