Answer:
B
Explanation:
the element is boron, therefore B is the symbol
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

Explanation:
We define the formal charge on an atom in a molecule as the charge it carries assuming that electrons in all chemical bonds of the molecule were shared equally between atoms irrespective of the electronegativity of each atom.
The formula for calculating the formal charge on an atom in a molecule is;
Formal Charge = [number of valence electrons on neutral atom] – [(number of lone electron pairs) + (½ number of bonding electrons)] ·
The formal charge on the two nitrogen atoms in diazomethane is obtained as follows;
Middle nitrogen atom = 5 – 8/2 – 0 = +1
Last nitrogen atom = 5 – 4/2 – 4 = –1
The Lewis structure of the molecule is shown in the image attached.
From the stoichiometry of the problem, 2.01 × 10^5 g of zinc phosphate is produced.
<h3>What is volume?</h3>
Volume is the product of width, height and depth. The significant figures of the width, height and depth are 5, 4 and 6 respectively.The volume of the box is; 11.014 × 10^-2 m × 0.2481 m × 523.735 × 10^-3 = 0.01431 m^3 or 14310 cm^3 or 0.5053ft^3.
Density of zinc = 7.140 g / cm3
Volume of zinc = 14310 cm^3
Mass of zinc = 7.140 g / cm3 × 14310 cm^3 = 102 Kg
Moles of Zinc = mass /molar mass = 102 × 10^3/65 g/mol = 1569 moles
There are 195 g of zinc in 386 g zinc phosphate
102 × 10^3 g of Zn will produce x g
x = 102 × 10^3 g × 386 g / 195 g
x = 2.01 × 10^5 g of zinc phosphate

The balanced nuclear equation for the reaction is
<h3>²³⁵₉₂U + ¹₀n —> ¹⁵⁵₆₂Sm + ⁷⁸₃₀Zn + 3(¹₀n)</h3>
From the question given above, we were told that:
<u>A fast-moving neutron strikes a ²³⁵U nucleus. The nucleus shatters producing ¹⁵⁵Sm, ⁷⁸Zn, and three neutrons.</u>
The nuclear equation can be written as follow:
Neutron => ¹₀n
Uranium => ²³⁵₉₂U
Samarium => ¹⁵⁵₆₂Sm
Zinc => ⁷⁸₃₀Zn
Uranium + neutron —> Samarium + Zinc + 3 moles of neutron
<h3>²³⁵₉₂U + ¹₀n —> ¹⁵⁵₆₂Sm + ⁷⁸₃₀Zn + 3(¹₀n)</h3>
The nuclear equation above is balanced.
