Answer:

   Acids change the color of litmus from blue to red.

   They convert the color of Methyl Orange from Orange/Yellow to Pink.

   Acids turn the pink color of Phenolphthalein to colourless.

   Acids can conduct electricity.

   Some Acids are highly corrosive in nature which means that they corrode or rust metals.

Answer: Acids have a sour taste

Aqueous solutions of acids are electrolytes, meaning that they conduct an electrical current.

Acids change the color of certain acid-base indicators.

Acids react with active metals to yield hydrogen gas.

Acids react with bases to produce a salt compound and water

What mass of H2 is needed to react with 8.75 g of O2 according to the following equation: O2(g) + H2(g) → H2O(g)?
alina1380 [7]

Mass of H₂ needed to react with O₂ : 1.092 g

<h3>Further explanation</h3>

The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight / volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.

Reaction

O₂(g) + 2H₂(g) → 2H₂O(g)

mass of O₂ : 8.75 g

mol O₂(MW=32 g/mol) :

\tt \dfrac{8.75}{32}=0.273

From the equation, mol ratio of O₂ : H₂ = 1 : 2, so mol H₂ :

\tt \dfrac{2}{1}\times 0.273=0.546

Mass H₂ (MW=2 g/mol) :

\tt 0.546\times 2=1.092~g

pogonyaev

Answer is: adenosine triphosphate.

ATP is made of three components: the triphosphate (P), the sugar ribose and a nitrogenous base (adenine).

ATP is short for adenosine triphosphate

Adenosine triphosphate converts to either the adenosine diphosphate (ADP) or adenosine monophosphate (AMP), in this process energy is released.

Which are examples of contact forces?
lesantik [10]

Answer:

Contact force is a force that requires a contact between two bodies and is ubiquitous in nature

Explanation:

The force is distributed in two categories i.e

  • Contact force
  • Non-Contact force

Contact Forces  are the forces which is requires a contact between two bodies to occur.

The Types of contact forces are given below:

  • Frictional Force
  • Tension Force
  • Normal Force
  • Air Resistance Force
  • Applied Force
  •  Spring Force

Some common daily examples of the contact force are

  1. Frictional force between the tyres of a moving vehicle and the road.
  2. Air flowing in opposite direction of a moving object.
  3. Pushing a table with hand and the friction between its base and floor.
  4. Stretching a rubber band with hands etc.

Also non-contact forces are Gravitational force, Electrical force and Magnetic force.
