The element is sodium. Atomic number is 11. Electron configuration is 2e- 8e- 1e-. Depends what reaction, because in a sodium and chloride reaction sodium loses 1 electron. Hope this helps

1. A 20m steel wire is stretched to 20.0m by
Eduardwww [97]

Answer:

Force to stretch the wire is 250 N

Explanation:

As we know that modulus of elasticity will remain the same for the wire if the applied stretch to the wire is within elastic limit

So we will have

\frac{F L}{\Delta L A} = constant

now we have

\frac{F_1 L}{\Delta L_1 A} = \frac{F_2 L}{\Delta L_2 A}

so we can write it as

F_2 = \frac{F_1 L_2}{L_1}

F_2 = \frac{50 (0.05)}{0.01}

F_2 = 250 N

A car is moving with a speed of 15 ms. How long does it take to cover a distance<br>of 1.2 km?​
fgiga [73]

Answer: 80 s

Explanation:

Speed is expressed in  v= d/t, derive the equation so we can have time.

First conert km into meters to cancel out both units and only seconds will remain.

1.2 km x 1000m/ 1km = 1200 m

t = 1200 m /15 m/s = 80 s
