1 bus = 12 cars
1 truck = 3 cars
4 trucks= 12 cars
1 bus = 4 trucks
1 bus = 4000 basketballs
8 buses= 32,000 basketballs

What happens when sodium and cholorine are mixed

tigry1 [53]

Answer:

The short of it is you would create salt.

Explanation:

If sodium metal and chlorine gas mix under the right conditions, they will form salt. The sodium loses an electron, and the chlorine gains that electron. This reaction is highly favorable because of the electrostatic attraction between the particles. In the process, a great amount of light and heat is released.

A ball of mass 0.2 kg is dropped from a height of 10 m. How much mechanical energy does it have right before it hits the ground?

lana [24]

Answer:

19.6 J

Step-by-step explanation:

Before the ball is dropped, it has a <em>potential energy </em>

PE = mgh

PE = 0.2 × 10 × 9.8

PE = 19.6 J

Just before the ball hits the ground, the potential energy has been converted into kinetic (<em>mechanical</em>) energy.

KE = 19.6 J

You have come down with a nasty cold and would like to understand why the virus that infected you is making you feel so lousy. W

umka21 [38]

Answer:

a) The volume is 5.236x10⁻¹³L

b) The molarity of a single virus is 1.91x10¹² mol/L

c) The molarity for a 100 virus particles is 1.91x10¹⁴ mol/L

Explanation:

a) Given:

D = diameter of the cell = 10 μm

r = radius = 10/2 = 5 μm

The volume of the spherical cell is equal:

$V=\frac{4}{3} \pi r^{3} =\frac{4}{3} \pi *(5)^{3} =523.6\mu m^{3}$

If 1 μm³ = 1x10⁻¹⁵L, then 523.6 μm³ = 5.236x10⁻¹³L

b) The molarity is:

$M=\frac{number-of-moles}{volume-of-solution}$

For a single virus within the cell

$M=\frac{1}{5.236x10^{-13} } =1.91x10^{12} mol/L$

c) For a 100 virus particles the molarity is:

$M=\frac{100}{5.236x10^{-13} } =1.91x10^{14} mol/L$
