You can start by writing out the molecular formula of each molecule.

Aluminum (Al 3+) Phosphate (PO4 3-)

AlPO4

Nickel II (Ni 2+) sulfide (S 2-)

NiS

Aluminum Sulfide

Al2S3

Nickel Phosphate

Ni3(PO4)2

If you’re wondering, we get those charges by looking at the periodic table. The metals usually have a + charge based on their group number. The nonmetals usually - charge egual to 8 - their group number.

You then balance the ions by flipping the charges, dropping the signs, and adding them in as subscripts.

Now we can put it into an equation


AlPO4 + NiS —-> Al2S3 + Ni3(PO4)2

Balance by adding coefficients

2 AlPO4 + 3 NiS —-> Al2S3 + Ni3(PO4)2

What is the rate constant of a reaction if rate = 1 x 10-2 (mol/L)/s, [A] is 2 M,
boyakko [2]

The rate constant of a reaction : 8.3 x 10⁻⁴

<h3>Further explanation</h3>

Given

rate = 1 x 10⁻² (mol/L)/s, [A] is 2 M,  [B] is 3 M, m = 2, and n = 1

Required

the rate constant

Solution

For aA + bB ⇒ C + D

Reaction rate can be formulated:

\large{\boxed{\boxed{\bold{r~=~k.[A]^a[B]^b}}}

the rate constant : k =

\tt k=\dfrac{rate}{[A]^m[B]^n}\\\\k=\dfrac{1.10^{-2}}{2^2\times 3^1}\\\\k=8.3\times 10^{-4}

A strong acid like hcl _____.a strong acid like hcl _____.dissociates completely in an aqueous solutionis a strong buffer at low
vladimir2022 [97]
Answer: A strong acid like HCl dissociates completely in an aqueous solution.

By definition a strong acid is that that dissociates completely in aqueous solutions. That means that all the molecules of the acid will be inoized into hydronium cation (H3O+) and anion (the negative radical).

For expample, HCl is a strong acid because

HCl + H2O----> H3O(+) + Cl-

The forwar arrow indicates that all the molecules of HCl reacted with the water for form the ions.

Explain how the random motion of molecules produces a concentration gradient and a net movement of solute
mixer [17]

Random motion of molecules produces a concentration gradient and a net movement of solute as  random movement of molecules causes diffusion that causes movement of molecules from high concentration to low concentration . No ATP is required in this process. This causes movement of solute molecules and causes concentration gradient.

How many milliliters of sodium metal, with a density of 0.97 g/mL, would be needed to produce 43.6 grams of sodium hydroxide in
GaryK [48]

Answer is: 25.84  milliliters of sodium metal.

Balanced chemical reaction: 2Na + 2H₂O → 2NaOH + H₂.

d(Na) = 0.97 g/mL; density of sodim.

m(NaOH) = 43.6 g; mass of sodium hydroxide.

n(NaOH) = m(NaOH) ÷ M(NaOH).

n(NaOH) = 43.6 g ÷ 40 g/mol.

n(NaOH) =1.09 mol; amount of sodium hydroxide.

From chemical reaction: n(NaOH) : n(Na) = 2 : 2 (1: 1).

n(Na) = 1.09 mol.

m(Na) = 1.09 mol · 23 g/mol.

m(Na) = 25.07 g; mass of sodium.

V(Na) = m(Na) ÷ d(Na).

V(Na) = 25.07 g ÷ 0.97 g/mL.

V(Na) = 25.84 mL.
