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

The pump in a water tower raises water with a density of rhow = 1.00 kg/liter from a filtered pool at the base of the tower up h
oee [108]

Answer:

Explanation:

mass of the water being lifted per second

m = volume x density

= 6.2 x 1 = 6.2 kg

height by which water being lifted

h = 75 - 21

= 54 m

increase in potential energy of water per second

mgh

6.2 x 9.8 x 54

= 3281.04 J /s

= 3281.04 W.

A copper wire (density equal to 8900 kg / m3) 0.3 mm in diameter "floats" due to the force of the earth's magnetic field, which
Andrews [41]

Answer:I=112.094\ A

Explanation:

Given

density \rho =8900\ kg/m^3

diameter d=0.3\ mm

Magnetic field B=5.5\times 10^{-5}\ T

Force on the current carrying conductor placed in a magnetic field

F=BIL\sin \theta

where L=length of conductor

\theta=angle between magnetic field and current

If the wire is floating then weight must be balanced by weight of wire

Weight=mg=\rho ALg

Therefore

\rho ALg=BIL\times \sin 90

8900\times \frac{\pi}{4}(0.3\times 10^{-3})^2L\times 9.8=5.5\times 10^{-5}\times I\times L

I=\frac{8900\times \pi\times 9\times 10^{-8}\times 9.8}{4\times 5.5\times 10^{-5}}

I=112.094\ A
