We can use the formula M₁V₁ = M₂V₂ the total volume of water that will yield 0.800 M HCl. We can then subtract that from the initial volume to get how much water needs to be added.

Since M₁V₁ = M₂V₂    (starting mole× starting volume = end mole × end volume)

⇒  (5 mol)(20 mL) = (0.80 mol) V₂

         100 mol/mL = 0.8 mol × V₂

⇒                      V₂ = 100 mol/mL ÷ 0.8 mol

                             = 125 m

Since we began with 20.0 mL of water,

water needed to add = 125 mL - 20 mL = 105 mL

Sulfuric acid reacts violently with alcohol and water to release heat. It reacts with most metals, particularly when diluted with water, to form flammable hydrogen gas, which may create an explosion hazard. ... Hazardous decomposition products are as follows: sulfur dioxide, sulfur trioxide, and sulfuric acid fumes.

it acts violently with water or alcohol to release some heat, it does react to most metals, mostly when diluted with water to form flammable hydrogen gases, which may create an explosion hazard.

In a movable pulley system, where does the other effort come from? is carried by this end of the rope. This means that the structure (ceiling) does half the effort.

Explanation:

Heat packs are used to relax muscles. This reaction is an example of exothermic reaction.

Exothermic reaction is defined as a reaction that is chemical in nature and is characterized by the release of energy in the form of heat and light.

It can also be defined as a thermodynamic process or reaction that releases energy from system to its surroundings.

Endothermic reaction is defined as the chemical reaction in which the reactants absorbs heat energy from the surroundings to form product.  

Endothermic reaction can also be defined as a reaction in which the system absorbs energy from its surroundings in the form of heat.

Being endothermic enables us to live in cooler environments and regulate our body temperatures in order to fight infection.

Thus, heat packs are used to relax muscles. This reaction is an example of exothermic reaction.

Ribosomes are called PROTEIN FACTORY

Ribosomes are involved in protein synthesis

Any metabolite or substance protein in nature can be synthesized on ribosomes

Since they are protein in nature hence can be synthesized on ribosome.

Answer:

Fiber-rich, complex carbs

Complex carbs with fiber take much longer to digest than simple carbs. This helps to maintain stable blood sugar levels because sugar enters the bloodstream gradually . Complex carbohydrates provide sustained energy and help you feel fuller for longer because they are digested more slowly.

Standardization is the process of titrating a solution that is prepared from: a carefully measured solid mass to accurately find the concentration of titrant.

Titration is also known as volumetric analysis (titrimetry) and it can be defined as a chemical process in which a solution of known concentration (titrant) is carefully and slowly added to another solution of unknown concentration, so as to determine the concentration or quantity of the analyte.

Similarly, a process referred to as standardization is used to titrate a solution that is prepared from a carefully measured solid mass to accurately find the concentration of titrant.

CaCO₃     →     CaO    +    CO₂

Find Moles of CO₂ Produced

Since the mole ratio of  CaCO₃  to CO₂ is 1 to 1,

the moles of CaCO₃ = moles of CO₂

moles of CaCO₃   = mass ÷ molar mass

                             = 300 g ÷ 100.087 g/mol

                             = 2.997 moles

∴ moles of CO₂ = 2.997 moles

Determine Mass of CO₂

Mass = moles × molar mass

         = 2.997 mol × 44.01 g/mol

         = 131.9 g

Light waves are part of the electromagnetic spectrum. The frequency of light therefore is 1.5 * 10^15 Hz.

Light is an electromagnetic wave and we know that the speed of light is a constant which is 3 * 10^8 m/s.

Knowing this; v = λ * f

λ = wavelength

f= frequency of light

v = seed of light

f = v/λ

f =  3 * 10^8 m/s/2.0 x 10-7 m

f = 1.5 * 10^15 Hz
