Density = (mass) / (volume)
4,000 kg/m³ = (mass) / (0.09 m³)
(4,000 kg/m³) x (0.09 m³) = mass
mass = 360 kg
force of gravity = (mass) x (acceleration of gravity) = (360 kg) x (9.8 m/s²) = (360 x 9.8) kg-m<span>/s² </span><span>= </span>3,528 newtons .
The balanced chemical equation is 2 AlI₃ + 3 HgCl₂
2 AlCl₃ + 3 HgI₂ for the given chemical reaction.
<h3>What is chemical equation?</h3>
Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

Answer:
the x and y values
Explanation:
because on the table the x is the input and y is the output
-- Since the sphere is a conductor, the charge on it will move around
until it's evenly distributed on the surface of the sphere. When every
tiny smitch of charge is the same distance from the charge around it,
they won't need to move around any more.
-- At that point, the situation at the center of the sphere will be:
For every smitch of charge on the surface, causing en electric field
at the center, there is another smitch, of the same size and in exactly
the opposite direction, canceling out the field of the first one.
Every smitch of charge on the surface causes a tiny bit of electric field
at the center, and they all cancel each other.
It turn out that if the sphere is hollow, then the electric field at EVERY
point inside it is zero, not only at the center.
It's exactly the same idea as a sphere with uniform, homogeneous mass.
For that sphere, the gravity at the center is zero.
Divide the net force by the mass:
<em>a</em> = (4.6 N) / (13 kg) ≈ 0.35 m/s²
also pointing backward, which looks like option B, but hard to say for sure since it's missing a decimal point.
