Answer:
ionic bonding occurs between ions and covalent bonding occurs when atoms have electrons in common (they share).
Answer: SMALLEST is lithium
LARGEST is Fluorine
Explanation:
Answer:
1.1 x 10⁴ J
Explanation:
To calculate eth energy needed, you need to use the following equation:
Q = mcΔT
In this equation,
-----> Q = energy/heat (J)
-----> m = mass (g)
-----> c = specific heat (4.184 J/g°C)
-----> ΔT = change in temperature (°C)
You can plug the given values into the equation and solve.
Q = mcΔT
Q = (75.0 g)(4.184 J/g°C)(55.0 °C - 20.0 °C)
Q = (75.0 g)(4.184 J/g°C)(35.0)
Q = 11,000 J
Q = 1.1 x 10⁴ J
Answer:
20
Explanation:
protons and nucleons have an atomic weight of 1
electrons carry no weight
hence the weight of the atom is
10 + 10 = 20
Answer:
a thing that is composed of two or more separate elements; a mixture.
