Double Replacement

Explanation:

Let's consider the following balanced reaction that occurs between aluminum sulfate and tripotassium phosphate.

Al₂(SO₄)₃ + 2 K₃PO₄ ⇒ 2 AlPO₄ + 3 K₂SO₄

This is a double replacement reaction because both salts exchange their cations and anions. So, PO₄³⁻ takes the place of SO₄²⁻ in Al₂(SO₄)₃ and SO₄²⁻ takes the place of PO₄³⁻ in K₃PO₄.

hi,

the answer is d, it has indefinite shape but definite volume.

hope this !

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
