Answer:
Explanation:
Mars is the fourth planet from the sun. Mars is more than 142 million miles from the Sun. A day on Mars is 24.6 hours. A year on Mars is 687 Earth days.
The amount of seawater that will be displaced would be 1.3274 x

<h3>Density and volume</h3>
Density = mass/volume.
Since a floating object displaces its own weight, a 4247 tons ship will also displace the same amount of water.
4247 tons of seawater = 3.8528 x
g
volume of 3.8528 x
g seawater = mass/density = 3.8528 x
g/1.025 = 3758829268.29 cubic centimeter.
3758829268.29
= 132741.80
or 1.3274 x

Answer:
lanthanum
Explanation:
lanthanum is an inner transition metal
For the basic solution:
11.2 = -log[H+]
[H+] = 6.31 x 10⁻¹²
For the acidic solution:
2.4 = -log[H+]
[H+] = 3.98 x 10⁻³
The difference:
3.98 x 10⁻³ - 6.31 x 10⁻¹²
≈ 4.0 x 10⁻³
The answer is B
