How many molecules are equal to 3.25 moles of carbon dioxide?

Answers

Answer:

1.957 × 10²⁴ molecules

Explanation:

The number of carbon dioxide molecules can be found by using the formula

N = n × L

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

N = 3.25 × 6.02 × 10²³

We have the final answer as

1.957 × 10²⁴ molecules

Susan is investigating physical changes. To do this, she places some ice into a large bowl and seals it with a lid. She leaves the bowl on the counter for several hours until all of the ice has melted. Using a balance, Susan determines that the mass of both the water and the ice are equal. Why is the mass of the ice and the water the same? (SC.8.P.9.1)

Answers

Answer:

No mass loss

Explanation:

The mass of ice and the water in the different state are equal because the same of quantity of matter is present in both state of matter of matter.

In essence, the mass of the physical change process is conserved. When mass is conserved, matter is neither created nor destroyed but can be changed from one form to the other. This is in compliance with the law of conservation of matter. So, no mass was lost in the physical change process and the mass will remain the same.

Given a balanced chemical equation it is always possible to determine
A)
the physical state of the products and reactants
B)
whether a reaction will or will not take place
C)
the relative number of moles taking part in the reaction
D)
the conditions necessary for the reaction to take place

Answers

Answer:

C) the relative number of moles taking part in the reaction

Explanation:

From a balanced chemical equation, it is always possible to determine the relative number of moles taking part in a chemical reaction.

The number of moles is the amount of the reacting specie that makes up a chemical reaction.

In balanced chemical equation, the number of moles of reactants and products must be the same. From this understanding, we can determine the amount of reactants and products needed for a chemical reaction to take place.

Which is the correct Lewis dot structure for BeH2 ?

Answers

H• •Be• •H --> H:Be:H
Since there are 4 valence electrons in total, Beryllium has 2 and Hydrogen has 2. You would put the Be in the middle because there is only 1 of them.

The correct Lewis dot structure for [tex]BeH_2[/tex] is Be : H : H

What does the Lewis dot structure show?

The Lewis dot structure shows the valence electrons as dots. The valence electrons of beryllium are shown as 2 dots on the left side of the atom.

The central atom, beryllium, has 2 valence electrons where each hydrogen atom has 1 valence electron. To form a stable molecule, beryllium shares its 2 valence electrons with the 2 hydrogen atoms, each of which shares its 1 valence electron with beryllium which gives each atom a full outer shell of electrons.

A group of tourists were on an outing when they noticed that precipitation began to fall. The air temperature was 32 degree Fahrenheit. What type of precipitation did they most likely see?

Answers

Answer:

The correct answer is - rain.

Explanation:

At 32 degrees c or zero degrees Celsius, droplets of water in the atmosphere do not freeze as it is not the temperature at which water freezes but it is the temperature at which ice melts.

At this temperature the water changes its state, below 32 degrees Fahrenheit the water freezes but in the atmosphere, it not freezes necessarily and remains in the liquid state and called super-cooled liquid or water. Above this temperature, water in liquid state.

Thus, the precipitation is in the form of rain.

The chemical equation describing the burning of hydrogen gas is: 2H2 + O2 ---> 2H2O.
Why is this both a synthesis and a combustion reaction?

Answers

Answer:

"A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve O2 as one reactant. The combustion of hydrogen gas produces water vapor." and "A synthesis reaction occurs when two or more reactants combine to form a single product. ... In a double replacement reaction, two compounds exchange elements. A combustion reaction occurs when a substance reacts quickly with oxygen. Combustion is commonly called burning"
