You are asked to write observations about a 100g sample of Nitrogen-16 before it decays, but you're running late. In order to make observations, you require at least .5g of material. Can you make observations if you are 57 seconds late to the lab?
Answer:
You cannot make observations if you are 57 seconds late into the lab.
Explanation:
The atomic nucleus can split by decay into 2 or more particles as a result of the instability of its atomic nucleus due to the fact that radioactive elements possess an unstable atomic nucleus.
Now, the primary particles which are emitted by radioactive elements in order to make them decay are alpha, beta & gamma particles.
The half life equation is;
N_t = N₀(½)^(t/t_½)
Where:
t = duration of decay
t_½ = half-life
N₀ = number of radioactive atoms initially
N_t = number of radioactive atoms remaining after decay over time t
We are given;
t = 57 secs
N₀ = 100 g
Now, half life of Nitrogen-16 from online sources is 7.2 seconds. t_½ = 7.2
Thus;
N_t = 100(1/2)^(57/7.2)
N_t = 0.4139g
We are told that In order to make observations, you require at least .5g of material.
The value of N_t you got is less than 0.5g, therefore you cannot make observations if you are 57 seconds late.

which best describes the relationship of substance particles in my neutral atom
Answer: The number of protons equals the number of electrons
Explanation:
The statement that describes the relationship of substance particles in my neutral atom is the number of protons equals the number of electrons. The correct option is C.
What are subatomic particles?Subatomic particles are the charged particles that are present inside the atoms. These particles are electron, proton, and neutron. The electron is negatively charged, a proton is positively charged and neutrons neutrally charges subatomic particle.
Neutron atoms are when there is no positive or negative charge present inside the atoms. This could happen when the negatively charged electron and positively charged proton combine, when negative and positive combines they become neutral.
Thus, the correct option is C. the number of protons equals the number of electrons.

how many moles of oxygen molecules can be produced from 6 moles of lead oxide
Answer:
Moles of oxygen molecules produced = 3 mol
Explanation:
Given data:
Moles of oxygen molecules produced = ?
Number of moles of lead oxide decomposed = 6 mol
Solution:
Chemical equation:
2PbO₂ → 2PbO + O₂
Now we will compare the moles of oxygen and lead oxide.
PbO₂ : O₂
2 : 1
6 : 1/2×6 =3 mol
three moles of oxygen molecules are produced.

[2nd Row L-R] - Force, Ionic, Covalent
[3rd Row L-R] - Atoms, Lost or Gained, Shared
[4th Row L-R] - More stable, Metal and Nonmetal, Nonmetal and Nonmetal
Explanation:
Chemical bonds are a force that hold together atoms in a substance to make compounds more stable.
Chemical bonds include two kinds: Ionic and Covalent.
Ionic in which electrons are lost or gained where attraction is between a Metal and Nonmetal.
Covalent in which electrons are shared where attraction is between a nonmetal and nonmetal.

Maria walked on a beach made mostly of sand. She walked barefoot
on the beach early in the morning, and the sand was cool. When she
walked in the same area in the afternoon, the sand was hot.
Which statement best describes why the temperature of the sand
increased?
The statement that the atoms in the sand were moving more quickly best describes why the temperature of the sand is increased. The relationship between kinetic energy and temperature is explained here.
What is the relationship between kinetic energy and temperature?The temperature of a body is directly proportional to the kinetic energy. The energy acquired by those molecules which are in motion is called the kinetic energy.
The radiation of the sun falls on a number of objects on our surroundings. The objects absorb this energy till afternoon due to which they become hot.
When Maria walked in afternoon, the sand was hot as its particles have gained the kinetic energy due to which they move rapidly from one place to another. So that the sand feels more hot in the afternoon.
Thus the atoms in the sand were moving more quickly best describes the increase in temperature of the sand.

A whale is swimming in the ocean. It communicates with another whale by sending out a sound. Which of the following best
describes how the sound gets to the other whale?
A.
All of the sound absorbed by water changes to heat before getting to the other whale.
В.
The sound is transmitted through water until it reaches the other whale.
C.
All of the sound is diffused in
the water until only a faint sound reaches the other whale.
.D
The sound is reflected in the water before it gets to the other whale.
Answer:
A.
The sound is transmitted through water until it reaches the other whale.
Explanation:
When one whale makes a sound, the sound is transmitted through water until it reaches the other whale. The sound causes a ripple-like effect in the water, producing waves that travel in the water. The waves are heard in all directions. This is why humans can hear the sounds animals make underwater.
The statement which best describes how the sound gets to the other whale is that all of the sounds absorbed by water change to heat before getting to the other whale. Thus, the correct option for this question is A.
How sound may transmit from one place to another?The transmission of sounds is generally carried out through a medium in the form of waves. These sound waves involve the pattern of disturbance caused by the movement of energy.
In an aquatic environment, when one whale successfully constructs a sound, the sound is effectively transmitted through the medium that is known as water.
It remains in the form of waves until it reaches the other whale. The sound in a waveform provokes a ripple-like effect in the water and travels in the water. The waves are effectively heard in all directions.
Therefore, the correct option for this question is A.

Which two changes of state can occur when a substance gains thermal
energy?
Answer:
Adding enough thermal energy to a substance can cause a change of state to occur. The change of state from a solid to a liquid is called melting. When energy is added to an ice cube, the ice particles speed up as energy is absorbed. When the particles move fast enough, the solid ice melts and becomes liquid water

There was a large population of woodpeckers living in a forest. Some of the woodpeckers had long beaks, some of the woodpeckers had short beaks. During a very rainy year, the bark on most of the trees grew very thick. Only the woodpeckers with the longest, strongest beaks could drill deep enough into the thick bark to find the insects they depend upon for food. Woodpeckers with short beaks could not drill in deep enough to reach the insects. If the rainy weather continues for several years, what do you expect would happen to the woodpecker population because of natural selection?
Answer:
The woodpecker population would start to decrease because of natural selection
