Answer:
B. 13a + 7b + 4.5c
Step-by-step explanation:
trust me bruh
I believe 3m 7cm 3cm= 13 meters :).
Your number is 34,699 right and if anything is 5000 or over round ahead so it is 30,000
-320. The negative sign represents loss. In all of the other cases, values are either being added or not changed at all.
Nitrogen Radius = 5.8 x 10⁻¹¹ m
Beryllium Radius = 1.12 x 10⁻¹⁰ m
Let's find the quotient of N/Be :
(5.8x10⁻¹¹)/(1.12x10⁻¹⁰). But 10⁻¹¹/10⁻¹⁰ = 10⁽⁻¹¹⁺¹⁰⁾ = 10⁻¹ = 1/10 = 0.1
→ (5.8/1.12).(0.1) = 0.58/1.12 = 0.518.
Conclusion: the radius of Be is almost double than the radius of N
