Answer:

The correct answer is sedimentary rock.

Explanation:

The sedimentary rocks are the types of rocks, which are produced due to the deposition and the succeeding cementation of that substance at the shallow part of the Earth and within the water bodies. In the geological sciences, sedimentation refers to the procedure of the deposition of the solid substance from a state of solution or suspension in a fluid, that is, water or air.

A. 2.0x1024 atoms of S to moles (3.3)
Fynjy0 [20]

3.3 moles of sulfur

Explanation:

To find the number of moles knowing the number of atoms we use Avogadro's number to formulate the following reasoning:

if in         1 mole of sulfur (S) there are 6.022 × 10²³ atoms of sulfur (S)

then in   X moles of sulfur (S) there are 2 × 10²⁴ atoms of sulfur (S)

X = (1 × 2 × 10²⁴) / (6.022 × 10²³)

X = 3.3 moles of sulfur

Fuel-cell cars use hydrogen gas and release ______ into the atmosphere.
iogann1982 [59]
Hi!

Fuel-cell cars only release water and heat in the atmosphere. 

Since they are only run by oxygen and hydrogen to produce electricity in the motor, they don't emit carbon dioxide or greenhouse gas as what other people think. 

Basically, automotive engineers and scientist classified them as zero-emission.

A student titrates a solution containing 0.050 moles of calcium hydroxide with phosphoric acid. How many moles of phosphoric aci
lina2011 [118]

Answer:

The answer to your question is 0.33 moles of H₃PO₄

Explanation:

Data

moles of Ca(OH)₂ = 0.050

moles of H₃PO₄ = ?

Process

1.- Write the balanced chemical equation

           3Ca(OH)₂  +  2H₃PO₄    ⇒   Ca₃(PO₄)₂   +   6H₂O

             Reactants        Elements       Products

                    3                      Ca                     3

                   12                       H                     12

                   14                      O                      14

2.- Calculate the moles of phosphoric acid

      3 moles of calcium hydroxide --------------- 2 moles of phosphoric acid

      0.5 moles of calcium hydroxide -----------   x

      x = (0.5 x 2)/3

      x = 0.33 moles
