Answer:

Substance at the beginning of a reaction- reactant

Substance at the end of a reaction- product

Number placed before a compound in a chemical equation- stoichiometric coefficient

Explanation:

In a reaction equation, the species written on the left hand side of the equation are called the reactants.

The reactants combine to form the species on the right hand side of the reaction equation called products.

The stoichiometric coefficient is a number written before the formula of a compound in the reaction equation.

Procaine hydrochloride (MW = 273) is a 2-ion electrolyte, dissociating 80%. Calculate its dissociation factor. Round to tenths p
Inga [223]

Answer:

Dissociation factor = 1.8

Explanation:

Data provided in the question:

Molecular weight of the Procaine hydrochloride = 273

Number of ions contained, n = 2

Fraction Dissociating, α = 80% = 0.8

Now,

the  dissociation factor 'i' is given as:

i = 1 + α × ( n - 1 )

on substituting the respective values, we get

i = 1 + 0.8 × ( 2 - 1 )

or

i = 1 + ( 0.8 × 1 )

or

i = 1.8

A 100 gram block is placed on a scale that is known to have a 12% error. What will the scale read?
sesenic [268]

The scale will read <u>112 grams.</u>

Why?

Since we already know the percent error of the scale (12%) and we also know the mass of the block that is placed on the scale, we can calculate what will be the read of the scale by using the following formula:

ScaleRead=100g+(100g*\frac{12}{100})=100g+(100g*0.12)=100g+12g\\\\ScaleRead=112g

We can see that the scale will read 112 grams.

Let's verify that we are right by using the following formula to verify if the obtained value for the scale read will be 12%:

PercentError=\frac{ActualValue-RealValue}{RealValue}*100=\frac{112g-100g}{100g}*100\\\\PercentError=\frac{12g}{100g}*100=0.12*100=12(percent)

Hence, we can see that the scale will read <u>112 grams.</u>

Have a nice day!

Carbon and oxygen combine to form carbon dioxide. What are the products, or what
Vladimir [108]
<h3>Answer:</h3>

Carbon dioxide

<h3>Explanation:</h3>
  • During chemical reactions elements or compounds that combine to form other new compounds are known as reactants
  • The newly formed compounds or molecules after a reaction has taken place are known as products.

In this case;

  • The chemical reaction between carbon and oxygen results to the formation of carbon dioxide.
  • The equation for the reaction is; C + O₂ → CO₂
  • Therefore, carbon and oxygen are the reactants while carbon dioxide is the product.

In the following chemical equation, identify the products and reactants and indicate whether or not the equation is balanced. If
aleksandr82 [10.1K]

Answer:

a). The products are C6H12O6 O2 and the reactants are CO2 + H20 + (solar (light) energy)

b). The reaction chemical reaction is balanced from the number of moles of reactants and products

Explanation:

Through photosynthesis green plants, some protistans and some bacteria in the presence of energy from sunlight, produce glucose as well as oxygen from carbon dioxide and water.

It is a chemical reaction taking place in green plant to produce food which it uses to survive.

Photosynthesis requires carbon dioxide, water and solar energy in the leaves of a plant for it to take place.

The equation for photosynthesis is as follows: 6CO2 + 6H20 + (solar (light) energy) → C6H12O6 + 6O2

The products are C6H12O6 O2

and the reactants are CO2 + H20 + (solar (light) energy)

The reaction chemical reaction is balanced from the number of moles of reactants and products
