The size of moon is one quarter of earth in diameter. It is fifth largest satellite in the solar system. The distance of moon from earth is 384,400 km. The radius of moon is 1,737,4 km. The gravity of moon is 1.62 m/sec^2.
The total surface area of moon is 3.793×10^7 km square and it's surface pressure is 10^-7 Pascal.There are total 8 phase of moon and these are new moon, first quarter, waxing gibbous, third quarter and waning crescent.
Therefore,Pluto's average distance from the Sun is about 3,666,000,000 miles and in inches it is 2.3227776e+14.

How do you determine the charge of an isotope?
Answer:
If the protons in the atom outnumber the electrons, the isotope has more positive charges than negative charges but If the number of electrons exceeds the number of protons, the ion charge will be negative.
Explanation:
The charge of an isotope is defined by how many more protons there are than electrons.
Or the other way around.
For example if there are 4 protons and 2 electrons, the ion charge is +2 because there are more protons.
If there are 4 electrons and 2 protons, the ion charge is -2 because there are more electrons.

Which measurement did they not use? *
mass
density
weight

volume
Answer:
volume
Explanation:
the mass is the same on earth as it is on the surface of the moon. The weight is determined by the force of gravity. The density is the thickness. But the volume is not a factor.

follow me and make me as brilliest.....Imagine you need to explain to a friend how to convert a value on a food label to one that is measured in grams. Assume the package of food has a mass of 1.0 pounds. write an explanation for how to use dimensional analysis to convert this value to one expressed in grams.
Answer:
453.592 grams
Explanation:
Given
Mass = 1 lb
Required.
Convert to grams using dimensional analysis
Represent 1 lb with x g
In unit conversion, we have that.
1 lb = 453.592 g
So:
Getting the equivalent of lb in g, we have:
x g = 1 lb * (453.592 g/ 1 lb)
x g = 1 * 453.592 g
x g = 453.592 grams
Hence:
The equivalent of 1 lb in grams is 453.592 grams
Calculate the mass of oxygen needed to react 10g of calcium to form calcium oxide. 2 Ca + O2→2 CaO
Answer:
Explanation:
1122 g CaO.
I hope I helped you! :)
The mass of oxygen needed to react 10 grams of calcium to form calcium oxide is 4.0 grams.
Given:
The reaction:
[tex]2Ca+O_2\rightarrow CaO[/tex]
Mass of calcium = 10 g
To find:
The mass of oxygen needed to react 10 grams of calcium to form calcium oxide.
Solution:
[tex]2Ca+O_2\rightarrow CaO[/tex]
Mass of calcium = 10 g
Moles of calcium = [tex]\frac{10 g}{40.078 g/mol}=0.25 mol[/tex]
According to reaction, 2 moles of calcium reacts with oxygen, then 0.25 moles of calcium will react with:
[tex]=\frac{1}{2}\times 0.25 mol=0.125 \text{ mol of }O_2[/tex]
Mass of 0.125 moles of oxygen gas:
[tex]0.125 mol\times 31.998 g/mol=3.99975 g\approx 4.0 g[/tex]
The mass of oxygen needed to react 10 grams of calcium to form calcium oxide is 4.0 grams.

How do the number of protons in an atom affect the atom's
identity?
Answer:
The number of protons in an atom define each individual element because the number of protons is the atomic number which is the defining property of an atom and never changes. The number of protons determines an atom's identity. For example, Oxygen has an atomic number of 8, so it has 8 protons, so no matter what ionic compound or molecule it's part of, every single Oxygen atom will always have 8 protons each.

difference between halogens and group 0 elements
Answer:
Colourless. Although they have similar properties they are not identical. For example, as you descend Group 0 the density of the gas increases as does the mass of a single atom. ... All the halogens exist as molecules, bonding covalently to their own atoms - adding stability as they complete their full outer shells.The difference between halogens and group 0 elements is that in their electronic configurations the halogens have 1 electron less than the stable octet while the zero group elements have stable octet.
What is electronic configuration?Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

A) S2O6
B) SO3
C) 2 SO3
D) 2 S and 6 O
Answer:
S2O6 best represents the bottom picture. When atoms are bonded in a molecule, the number of them is represented as a subscript in a chemical formula.
Explanation:
The symbolic notation that best represents the molecule in the bottom picture is S2O6.
Sulfur is a chemical element that has the symbol S. It also has the atomic number of 16. It should be noted that sulfur is known as the 10th most abundant element that we've in the universe.It should be noted that S2O6 is the chemical formula for Disulfur Hexoxide.

a beaker contains 0.250 l of liquid. a student pours 0.00385 L of liquid out of the beaker. How much liquid remains in the beaker? choose the value reported with the correct number of significant figures
Answer:
The volume of the liquid remaining in the beaker is 0.24615 l
Explanation:
The initial volume of liquid in the beaker = 0.250 l
The volume of liquid the student pours out of the beaker = 0.00385 l
The volume of liquid remaining in the beaker, V, is given as follows;
V = The initial volume of liquid in the beaker - The volume of liquid the student pours out of the beaker
Therefore, we have;
V = 0.250 l - 0.00385 l = 0.24615 l
The volume of the liquid remaining in the beaker is 0.24615 l.
A student places 1.38g of unknown metal at 99.6C into 60.50g of water at 22.1C. The entire system reaches a uniform temperature at 31.6C. Calculate the specific heat of the metal
Explanation:
Heat energy lost by metal = Heat energy gained by water.
(0.00138kg) * c * (99.6-31.6) = (0.006050kg) * 4.148 * (31.6-22.1)
c = 2.541J/kg°C

lago claro todo esta lleno de basura
Answer:
I think its about the same tempurature so i would say 32 degrees
Explanation:
Notice that the curve shows periods where the temperature does not change. These plateaus occur because energy is being used to changing the substance's phase, not raise the temperature. This is why water will not get hotter as it is boiling.
