Answer:
Forces inside the atom
The atom is comprised of three major particles—protons, neutrons and electrons. There are four forces (Electromagnetic, Strong, Weak, and Gravity) that are responsible for the behavior of the particles and thus keep the atom together.
Answer:
B. Evaporation and condensation
Explanation:
Evaporation includes a phase change from liquid to gas. Condensation includes a phase change from gas to liquid. Also, It is the invisible process of evaporation that changes liquid and frozen water into water-vapor gas, which then floats up into the skies to become clouds. Hope this helps!!
Answer: 24 N
Explanation: solution attached:
F = ma
= 6.0 kg ( 4.0 m/s²)
= 24 N
g - Measurement of Mass
m² - Measurement of Area
m³ - Measurement of Volume
km- Measurement of Length
Answer: Synthesis
0.84 moles of oxygen
25 moles of
Explanation:
The balanced chemical equation is:
This is a synthesis reaction as one product is formed by combination of two reactants.
According to stoichiometry :
a. 2 moles of require = 3 moles of
Thus 0.56 moles of require= of
b. 4 moles of give = 2 moles of
Thus 50 moles of give = of
