Answer:
Earth is made of several subsystems or "spheres" that interact to form a complex and continuously changing whole called the Earth system. to thousands of kilometers, and on time scales that range from milliseconds to billions of years of the Earth; earthquake; Examples of long term - making coal; plate tectonics
Explanation:
The net ionic equation is shorter to use and already leaves out the electrons that transferred from the reducing agent to the oxidizing agent. Also, in some occasions the aqueous ions H+ and (or) OH- ions that help balance the net ionic charge are no longer shown in the net ionic equation.
Answer:
Specific heat capacity = 0.24 j/g.°C
Explanation:
Given data:
Mass of metal = 82.4 g
Heat absorbed = 846 j
Change in temperature = 67°C - 25°C
Specific heat capacity = ?
Solution:
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 = 67°C - 25°C
ΔT = 42°C
Q = m.c. ΔT
846 j = 82.4 g . c. 42°C
c = 846 j / 3460.8 g.°C
c = 0.24 j/g.°C
170 Im pretty sure. It bounces off at the same angle as it is striked
14mg to kg
1kg = mg /1,000,000
Answer would be
0.000014kg
