name of atom is atomos, Figure 4.The symbol for an atom indicates the element via its usual two-letter symbol, the mass number as a left superscript, the atomic number as a left subscript (sometimes omitted), and the charge as a right superscript.
Atomic mass is defined as the number of protons and neutrons in an atom, where each proton and neutron has a mass of approximately 1 amu (1.0073 and 1.0087, respectively). The electrons within an atom are so miniscule compared to protons and neutrons that their mass is negligible.
The number fifteen in Angel numerology marks the manifestation of a harmonious life, a synthesis of matter and spirit. Angel number 15 refers to the material and spiritual, steady flow of energy, the source of power and cooperation.
In statistical testing, the p-value is the probability of obtaining test results at least as extreme as the results actually observed, under the assumption that the null hypothesis is correct. A very small p-value means that such an extreme observed outcome would be very unlikely under the null hypothesis.
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth.
High MCH scores are commonly a sign of macrocytic anemia. This condition occurs when the blood cells are too big, which can be a result of not having enough vitamin B12 or folic acid in the body
The mass number tells us the number (the sum of nucleons) of protons and neutrons in the nucleus of an atom. ... The atomic number uniquely identifies a chemical element. In an atom of neutral charge, atomic number is equal to the number of electrons.
number of protons = atomic number.
number of electrons = atomic number.
number of neutrons = mass number - atomic number.

When 0.80 grams of Helium are added to a weather balloon, its volume is 6.0 L. If the pressure and temperature do not change, how many more grams are needed to make the balloon have a volume of 8.0 L? Enter 20 Acellus Corporation. All Rights Reserved. A Using Alternative Server g
Answers
Answer:
More grams needed = 0.28 g
Explanation:
Given data:
Initial mass of He = 0.80 g
Initial volume = 6.0 L
Final volume = 8.0 L
More grams needed = ?
Solution:
Number of moles of He:
Number of moles = mass/molar mass
Number of moles = 0.8 g/ 4 g/mol
Number of moles = 0.2 mol
Formula:
V₁/n₁ = V₂/n₂
6.0 L/ 0.2 mol = 8.0 L/ n₂
n₂ = 8.0 L× 0.2 mol /6.0 L
n₂ = 1.6 L.mol /6.0 L
n₂ = 0.27 mol
Final Grams:
Mass = number of moles × molar mass
Mass = 0.27 mol × 4 g/mol
Mass = 1.08 g
More grams needed = Total - initial
More grams needed = 1.08 g - 0.80
More grams needed = 0.28 g

A wave is a disturbance that transfers _____ from one place to anothe
Answers
Answer:
Energy
Explanation:
A wave is a disturbance that transfers energy from one place to another. During this transfer of energy, matter is not usually affected. Waves can be propagated through a material medium or in a vacuum.
Waves that are propagated in a material medium are called mechanical waves.
Those propagated through a vacuum are the electromagnetic waves.

Why does a radioisotope undergo nuclear decay ?
A. To become more stable
B. To become less stable
C. To gain energy in the nucleus
D. To bond with other atoms
Answers
Answer:
A) To become more stable .
A radioisotope undergo nuclear decay to become more stable. Therefore, option A is correct.
What is nuclear decay ?The term nuclear decay is defined as the set of different processes by which an unstable atomic nucleus spontaneously emits subatomic particles.
There are three common types of decay are alpha decay (α-decay), beta decay (β-decay), and gamma decay (γ-decay), all are involve in emitting one or more particles.
When a radioisotope experiences nuclear decay, its nucleus emits particles that change it into a new, potentially radioactive isotope. A proton will become a neutron and release a beta-plus particle (positron), which is an electron with a positive charge, if an unstable nucleus has too many protons.
Thus, option A is correct.

It carries energy.
It carries matter.
Answers
Answer:
It’s caused by a disturbance.
It requires a medium to travel.
Explanation:
A wave is an unsettling influence that sends energy starting with one point then onto the next. It does no essentially convey the particles or matter of the medium.
Waves typically conveys energy. It is this energy they use in making aggravations.
Not all waves conveys matter; a genuine model is electromagnetic waves. Additionally, electromagnetic waves don't need a mode for proliferation.
Answer: The only answer that is NOT true is that waves carry matter.
Explanation:
Waves are caused by a disturbance, require a medium to travel (by definition) and carry energy.
If you're talking about electromagnetic waves tho, those do not require a medium. Waves in general DO require a medium

Two solid blocks are HEATED to the temperatures show. The blocks are placed so they touch. Which diagram shows the DIRECTION HEAT WILL FLOW?
Answers
Answer:
Heat flows from the block at high temperature to the one with lower temperature
Explanation:
The direction of heat flow is from a body at higher temperature to one with a lower temperature.
Temperature gradient determines the way and manner in which heat is dissipated. As a system tend to increase entropy, it ensures that heat moves from hotter body to a colder body. Heat movement here is by conduction as the body touches. When both bodies reaches the same temperature, thermal equilibrium is established.Answer:

What is the effect of diuron on ATP, NADPH, and sugar?
ATP : increase? decrease? no change?
NADPH: increase? decrease? no change?
Sugar: increase? decrease? No change?
Answers
The application of diuron decreases the activity of ATP, NADPH, and sugar production.
• Diuron is an active herbicide and algaecide, which prevents the process of photosynthesis and hinders the tendency of the weed to turn light energy into chemical energy.
• It prevents the process of photosynthesis by preventing the production of oxygen and blocks the transfer of electrons of photosystem II in plants, thus, preventing the electron transport chain.
• This eventually decreases the production of ATP, NADPH, and sugar in plants.
Thus, diuron decreases ATP, NADPH, and sugar.
