Answer:
weathering and erosion
Explanation:
Sand forms when rocks break down from weathering and eroding over thousands and even millions of years. Rocks take time to decompose, especially quartz (silica) and feldspar. Often starting thousands of miles from the ocean, rocks slowly travel down rivers and streams, constantly breaking down along the way.
Answer/Explanation :Molecules of Aspirin (C9H8O4), Acetaminophen (C8H9O2N), and Aspartame. (C14H18O5N2) [white spheres are hydrogen, black are carbon, red are oxygen, and convert between grams (mass), moles, and number of atoms .
Answer:
There will be more repulsive force between the electrons.
Explanation:
Electrons contain negative charge.As a result the electron will repulse another adjacent negatively charged electron.
According to the given question addition of electrons to en energy level without adding more protons will increase the overall negative charge in the the energy level in which the electrons are added.
This ultimately leads to generate more repulsive force between the electrons.
Answer:
metals donate electrons to nonsmetals
Answer:
The given substance is cast iron.
Explanation:
Given data:
Mass of substance = 50 g
Heat absorbed = 23000 J
Initial temperature = 250°C
Final temperature = 1250°C
Which metal is this = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 1250°C - 250°C
ΔT = 1000°C
23000 j = 50 g ×c ×1000 °C
23000 J = 50,000 g. °C×c
c = 23000 J /50,000 g. °C
c = 0.46 J/g.°C
The given substance is cast iron.
