The energy is transferred throughout the rest of the metal by the moving electrons. Metals are described as
malleable (can be beaten into sheets) and ductile (can be pulled out into wires). This is because of the ability of the atoms to roll over each other into new positions without breaking the metallic bond.
Vitamin K and potassium are essential micronutrients the body needs to develop and function properly. The two share some things in common, but they’re not the same.
Each has a unique set of properties and purposes. Unlike vitamin K, potassium is not a vitamin. Rather, it’s a mineral.
On the periodic table, the chemical symbol for potassium is the letter K. Thus, people sometimes confuse potassium with vitamin K.
This article highlights some of the main similarities and differences between vitamin K and potassium.
Answer:
THE AMOUNT OF HEAT ABSORBED DURING THE REACTION IS 151.64 JOULES
Explanation:
Mass = 12.58 g
Specific heat of CaCO3 = 0.82 J/g K
Change in temperature = 38.3 C - 23.6 C = 14.7 C
How many joules of heat are absorbed?
Heat of a reaction is the amount of heat absorbed or evolved when a gram of a sample is raised by 1 C.
Heat = mass * specific heat * change in temperature
Heat = 12.58 * 0.82 * 14.7
Heat = 151.64 J
The amount of joules absorbed during this reaction is 151.64 J.
