What does the number on the top right of the symbol show? If the value here is 0, what does that mean
Answer:
Explanation:
The number on the top right of the symbol shows ATOMIC NUMBER , if it is written alone only one digit or number overall .
And if the number is also in bottom left then bottom left number will be ATOMIC NUMBER and top right will be MASS NUMBER
Hope this will help you *-*
Answer:
Explanation:
The number at the top right shows the electrical charge of the atom. A value of 0 means the atom is neutral, which means that the atom has the same number of electrons and protons.
This element has three fewer protons than oganesson 
Answer:
ununpentium
Explanation: this is element 115, Oganesson has 118
The atomic number of oganesson is 118. The element which is having three fewer protons than oganesson is moscovium (Mc) (115).
What is oganesson?
Oganesson is a newly found element synthesized in 2002 and is placed as 118'th element in the periodic table. In modern periodic table, the elements are arranged based on their atomic number.
Atomic number is the number of protons in the atom as well it is the number of electrons in the neutral atom. For a neutral atom the number of electrons are protons are equal.
Thus in a neutral atom the positive charges are neutralized by equal number of negative charges.
Thus, for 118'th element, there are 118 protons, three fewer from this means, there are 115 protons, the 115'th element in the modern periodic table is moscovium.

Coyotes and oak trees are unicellular organisms?
Answer :
Multicellular organismsExplanation :
Coyotes are multicellular organisms.
Trees are multicellular organisms. They are made up of eukaryotic cells, which are complex cells full of organelles.
Coyotes and oak trees are not unicellular organisms but are multicellular organisms.
Unicellular organisms are living organisms that consist of only one cell. These organisms are complete and functional in their single-cell structure, carrying out all essential life processes, such as respiration, nutrition, reproduction, and growth, within that one cell. Examples of unicellular organisms include bacteria, archaea, protozoa, certain algae, and some fungi.
Coyotes and oak trees are multicellular organisms made up of many cells. Coyotes are mammals, and oak trees are plants, both of which are complex organisms with specialized tissues and organs. In contrast, unicellular organisms, such as bacteria and protists, carry out all life processes within a single cell.

The law of conservation of energy states that energy can neither be created nor destroyed; however, if you stretch out a ball in your hand and let it freely drop, the ball will not quite bounce back up to the height you dropped it from. Which of the following best explains why this happens? *
The pull of gravity negates the law of conservation of energy.
Some of the energy has to be used up to push the ball back into the air, destroying it forever.
The ball falls too quickly, so the energy does not have enough time to fully recharge.
Some of the energy is released into the air as heat (thermal energy) due to friction.

Answer:D
Explanation:
Got it right
The statement which provides the theme of valuing all life found in the poem 'Birdfoot's Grampa' is the journey is more important than the destination.
What is the theme of Birdfoot's Grampa?The poem 'Birdfoot's Grampa' is written by the author Joseph Bruchac which narrates the story of an old man's journey to rescue the life of all toads that are seen on the road while he is driving during the night.
The poem gives us an idea that all life is important and is of value which we can understand through the immense tolerance and selflessness. The worth of our life is generally demonstrated in the poem.
Every ones life has a value whether it is small or big. This concern is shown in this poem through the character of Birdfoot's Grampa's continuous stopping of the car to rescue the toads which are seen on the road rather than just running them over.
Birdfoot's Grampa's is that much conscious and careful about the life of toads. All life is precious and the journey is more important than the destination is denoted in the poem.
Thus option A is correct - journey is more important than the destination.

google takes its name from a conversion prefix. What is it and how big is it
Answer:
Giga, 1x10⁹.
Explanation:
Hello,
In this case, if we chew over Google's name, we can see that it suggests the word Giga which in conversion units context accounts for the Giga prefix (G) which has a value of 1x10⁹.
For instance 1 meter in gigameters is:
[tex]1m*\frac{1Gm}{1x10^9m}=1x10^{-9}Gm[/tex]
Which suggests that it is a huge unit and it makes sense considering the raft of information Google handles.

If an object has a mass of 45g and a volume of 9 cubic centimeters, what is its density? been wroking forever
A.405g/cubic centimeters
B . 5g/ cubic centimeters
C > 4g/ cubic centimeters
0.2g/ cubic centtimeters
Answer:
The answer is option BExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question
mass of object = 45 g
volume = 9 cm³
Substitute the values into the above formula and solve
We have
[tex]density = \frac{45}{9} \\ [/tex]
We have the final answer as
5.0 g/cm³Hope this helps you
Answer:
the answer is B 5g/ cubic centimeters
Explanation:
to find the density you divide the mass by the volume
How do scientists determine the number of neutrons in an isotope of an atom? O They find the number of protons. 0 They add the number of electrons and protons. They divide the atomic mass by two. They subtract the atomic number from the atomic mass.
Answer:
The three naturally-occurring isotopes of hydrogen. The fact that each isotope has one proton makes them all variants of hydrogen: the identity of the isotope is given by the number of protons and neutrons. From left to right, the isotopes are protium (1H) with zero neutrons, deuterium (2H) with one neutron, and tritium (3H) with two neutrons.
The term isotope is formed from the Greek roots isos (ἴσος "equal") and topos (τόπος "place"), meaning "the same place"; thus, the meaning behind the name is that different isotopes of a single element occupy the same position on the periodic table.[2] It was coined by a Scottish doctor and writer Margaret Todd in 1913 in a suggestion to chemist Frederick Soddy.
The number of protons within the atom's nucleus is called atomic number and is equal to the number of electrons in the neutral (non-ionized) atom. Each atomic number identifies a specific element, but not the isotope; an atom of a given element may have a wide range in its number of neutrons. The number of nucleons (both protons and neutrons) in the nucleus is the atom's mass number, and each isotope of a given element has a different mass number.
For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively. The atomic number of carbon is 6, which means that every carbon atom has 6 protons, so that the neutron numbers of these isotopes are 6, 7, and 8 respectively.
Which answer below correctly identifies the type of change and the explanation for the boiling of water?
physical change because even though the change caused the temperature of the water to increase,
the water's physical properties remained exactly the same
physical change because even though gas formation was observed, the water was undergoing a
state change, which means that its original properties are preserved
chemical change because gas formation was observed, which indicated that the water was
transformed into a different substance
0 chemical change because a temperature change was observed, which indicated that the water was
transformed into a different substance
Answer: physical change
Explanation:
as the water heats up the atoms begin to move faster changing the physical form

The answer is 9.76 mLExplanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} \\ [/tex]
From the question
mass of gold = 200 g
density = 20.5 g/mL
It's volume is
[tex]volume = \frac{200}{20.5} \\ = 9.7560975609...[/tex]
