Refer to how 2 electrons bond together when near a magnetic force
Answer:
Glucose is a primary source of energy for living organisms. Animals transport glucose and oxygen to tiny structures in their cells, called mitochondria.
Hope this helps ;-))
Answer:
halogens
Explanation:
Electronegativity increases as you move to the right and up the periodic table. Thus, halogens would have the greatest electronegativity.

Answer:
Q = 1.44×10⁴ J
Explanation:
Given data:
Mass of water = 62.5 g
Initial temperature = 25.5°C
Final temperature = 80.7°C
Specific heat capacity of water = 4.184 J/g.K
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 = 80.7°C - 25.5°C
ΔT = 55.2 °C
Q = 62.5 g × 4.184 J/g.°C × 55.2 °C
Q = 14434.8 J
Q = 1.44×10⁴ J
