Answer:

A chemical reaction in which an uncombined element replaces an element that is part of a compound is called a simple substitution reaction or simple displacement reaction.

Explanation:

A simple substitution reaction or simple displacement reaction, called single-displacement reaction, is a reaction in which an element of a compound is substituted by another element involved in the reaction. The starting materials are always pure elements and an aqueous compound. And a new pure aqueous compound and a different pure element are generated as products. The general form of a simple substitution reaction is:

AB + C → A +BC

where C and A are pure elements; C replaces A within compound AB to form a new co, placed CB and elementary A.

So, in a Single replacement reaction an uncombined element replaces an element.

A chemical reaction in which an uncombined element replaces an element that is part of a compound is called a simple substitution reaction or simple displacement reaction.

What is a saturted solution

andrew-mc [135]

Answer:

Please find the definition and further explanation below

Explanation:

Based on the ability for the solvent (liquid substance) to dissolve a solute (solid substance), a solution can either be unsaturated, saturated or supersaturated. A SATURATED SOLUTION is that which contains the maximum amount of solute a solvent can possibly dissolve.

In other words, a saturated solution can no longer dissolve anymore solute, and hence, any further solute added forms crystals or makes the solution supersaturated.

What effect is climate change having on the amount of water in liquid, solid, and gas forms on Earth?

enyata [817]

Increased temperatures cause changes in atmospheric circulation and increase evaporation and water vapor, resulting in precipitation increases, more intense precipitation, more storms and sea level rise.

Calculate the mass of water produced from the reaction of 2.00 grams of hydrogen and 4.00 grams of oxygen.

disa [49]

Answer:

4.50 g of H₂O

Explanation:

The Balance chemical equation is

2 H₂ + O₂ = 2 H₂O

Step 1: Calculate Limiting Reagent

Moles of H₂

Mole = 2 g / 2.02 g/mol = 0.99212 mol

Moles of O₂

Mole = 4 g / 32.00 g/mol = 0.125 mol

Mole ratio of H₂ : O₂ is 2 : 1. Hence, 0.99212 mol of H₂ will need 0.49606 mol of O₂. This means O₂ is limiting reagent.

Step 2: Calculate Moles of H₂O

0.125 mol of O₂ will produce 0.250 mol of H₂O because the mole ratio of O₂ : H₂O is 1 : 2.

Step 3: Calculate mass of H₂O

Mass = 0.250 mol × 18.02 g/mol = 4.50 g of H₂O

The phase change h2(g) → h2(s) is called ________, and the enthalpy change, δh, for this phase change has a ________ sign.

Tpy6a [65]

The phase change H₂(g) → H₂(s) is called deposition, and the enthalpy change, ΔH, for this phase change has a negative (-) sign.
Deposition is a thermodynamic process in which gas transforms into solid without passing through the liquid phase. Example is formin snow in clouds directly from water vapor. In deposition energy is released.
