Answer:
magnesium has a higher ionization energy because its radius is smaller. calcium has a higher ionization energy because it outermost sub-energy level is full. they have the same ionization energy because they have the same number of valence electrons.

Answer:
Density
Explanation:
If the fishing weight is more dense than the water, it will sink and if it less dense it will float. hope this helps :)
Answer:
V = 1.434 L
Explanation:
Given data:
Mass of argon = 4.24 g
Temperature = 58.2 °C
Pressure = 1528 torr
Volume = ?
Solution:
58.2 °C = 58.2 + 273 = 331.2 K
1528/760= 2.01 atm
<em>Number of moles:</em>
Number of moles = mass/molar mass
Number of moles = 4.24 g / 39.948 g/mol
Number of moles = 0.106 mol
<em>Volume:</em>
PV = nRT
V = nRT/P
V = 0.106 mol ×0.0821. atm. L. mol⁻¹. K⁻¹ × 331.2K/ 2.01 atm
V = 2.88 atm L/ 2.01 atm
V = 1.434 L
Explanation:
During the formation of BeCl2, the beryllium atom bonds with two chlorine atoms via single covalent bonds. The number of electron pairs around the central atom will be two. No lone pair is found in the molecule. If we analyse this information then we can conclude that BeCl2 has sp hybridization.
the cathode
Answer:
B. tension
Explanation:
a straight stretched rubber band experiences tension which is a stress that tries to pull matter apart.
