what is endothermic process?
Answer:
An endothermic process is any process with an increase in the enthalpy H (or internal energy U) of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system. It may be a chemical process, such as dissolving ammonium nitrate in water, or a physical process, such as the melting of ice cubes.

how is geologic activity & geologic structure similar?
Explanation:
Geological activity determines geological structures. The prevalent types and forms of tectonic working in a place will control the form of structure that can be found in a terrain.
In volcanic region, it is common to see volcanic structures of different types such as calderas, strato-volcano etc. These structures are formed by the volcanic activities. Also, in a karst topography, we find sink holes, stalactites and stalagmites etc. due to the nature of the geologic activities going on. Some sedimentary rocks shows cross bedding due to the environment where they form.So, geologic activities controls the structure found in an area

The Pauli Exclusion Principle tells us that no two electrons in an atom can have the same four quantum numbers.
Enter ONE possible value for each quantum number of an electron in the orbital given.
Orbital n l ml ms
1s There are a total of values possible for ml.
2s There are a total of values possible for ml.
Answer:
See explanation
Explanation:
We can describe electrons using four sets of quantum numbers;
principal quantum number (n)
orbital quantum number (l)
magnetic quantum number (ml)
spin quantum number (ms)
Since no two electrons in an atom can have the same value for all four quantum numbers according to Pauli exclusion theory, for the orbitals given one possible value for each quantum number is shown below;
For 1s-
n = 1, l= 0, ml = 0, ms= 1/2
For 2s-
n= 2, l =0, ml=0, ms=1/2
For 1s and 2s orbitals, there is only one possible value for ml which is zero.
Reaction type for this equation
2 AgNO3 + Cu → Cu(NO3)2 + 2 Ag
Answer:
single displacement reaction
The given chemical equation represents single displacement reaction as an more reactive element displaces less reactive element from it's compound.
What is chemical equation?
Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

In determining the density of a rectangular metal bar, a student made the following measurements length 8 53 cm, width, 24 cm, height 10 cm, mass, 527064 g Calculate the
density of the metal to the correct number of significant figures
Answer:
d = 2.57456 g/cm³
Explanation:
Given data:
Length of metal bar = 853cm
Width = 24 cm
Height = 10 cm
Mass = 527064 g
Density of metal = ?
Solution:
Volume of metal bar:
Volume = length × width × height
Volume = 853 cm × 24 cm × 10 cm
Volume = 204720 cm³
Density:
d = m/v
d = 527064 g / 204720 cm³
d = 2.57456 g/cm³

D. The plates are different in size from the landmasses.
Answer:
D. The plates are different in size from the landmasses.
Explanation:
The tectonic plates that are also called lithospheric plates are very massive and irregular-shaped rocks that are composed of both the continental and the oceanic lithosphere and they may vary from a few hundred to thousands of square km.Based upon the context clues of the lesson, what do you think will be the relationship between Charles and his parents

How many atoms of each element are present in
Si (SO4)3 Ca(OH)2
3.2 moles of K2SO3
4 moles of oxygen
Answer:
1.156x10²⁵ atoms and 4.8x10²⁴ atoms of oxygen
Explanation:
1 mole of a molecule X contains 6.022x10²³ molecules. In a molecules as H₂O, for example, there are 3 atoms (2 of H and 1 of O).
Thus, in 1 molecule of K₂SO₃ there are 6 atoms (2 of K, 1 of S, 3 of O). In 3.2 moles there are:
3.2mol K₂SO₃ * (6.022x10²³ molecules / 1mol) = 1.927x10²⁴ molecules.
The atoms are:
1.927x10²⁴ molecules * (6atoms / molecule) =
1.156x10²⁵ atoms
In 4 moles of oxygen, O₂, there are 2 atoms per molecule :
4mol * (6.022x10²³ molecules / mol) = 2.4x10²⁴ molecules * (2atom / molecule) =
4.8x10²⁴ atoms of oxygen
