Answer is beryllium.
The electronegativity trend is that it increases from left to right in a period and from bottom to top in a group. This is why fluorine has the highest electronegativity out of all the elements. So since beryllium is at the very top of the group, it has the highest electronegativity

Answer: 1,762.97 ft² ≈ 1,763 ft²
Explanation:
1) Conversion factor:
1 ft = 0.305m ⇒
1 = 1 ft / 0.305m ⇒
´[1]² = [1 ft / 0.305m]² ⇒
1 = 1 ft² / (0.305m)² ⇒
1 = 1 ft² / 0.093025 m²
2) 164 m²
164 m² × 1 ft² / 0.093025 m² = 1,762.97 ft² ≈ 1,763 ft²
Answer:
The temperature of the system once the equilibrium has been reached = 372.55K
Explanation:
Heat capacity of gold = 129 J/Kg*c.
Heat capacity of water
4,184 J/Kg*c.
Mass of gold = 75g = 0.075Kg
Mass of water = 200g = 0.2Kg
From conservation of energy
m1×C1×(t11 - t2) = m2×C2×(t2- t21)
Substituting we have
0.075 × 129×(1000-t2) = 0.2× 4184×( t2 -300) =solving for t2, we have
933.55×t2 = 347790
or t2 = 372.55K
The temperature of the system once the equilibrium has been reached = 372.55K
Answer:
For example, the chemical formula for water is H2O which indicates that 2 atoms of Hydrogen combines with 1 atom of oxygen.
Explanation:
The chemical formula for sodium chloride (Salt) is NaCl indicating that one atom of sodium combines with one atom of chlorine in a one-to-one ratio.
