The reaction is a synthesis reaction.

<h3>What are synthesis reactions?</h3>

Synthesis reactions are one of the numerous reactions in chemistry. These kinds of reactions involve the combination of two atoms of different elements resulting in the formation of new compounds.

Synthesis reactions are sometimes referred to as combination reactions, simply because they have to do with the combination of two or more atoms of different elements into a single compound.

The different elements that combine are referred to as the reactants while the result of the combination is known as the product.

For example: A + B --> AB

In the illustrated reaction, N2 combined with H2 to form NH3. N2 and H2 gases are the reactants while NH3 is the only product formed from the two reactants.

This is a good example of a synthesis/combination reaction.

Considering the limiting reactant, what is the mass of zinc sulfide produced from 0.250 g of zinc and 0.750 g of sulfur? Zn(s)+S

DIA [1.3K]

Answer:

The mass of zinc sulfide produced is $M_{ZnS} = 0.76 \ g$

Explanation:

From the question we are told that

The mass of zinc is $m_z = 0.750 \ g$

The mass of sulfur is $m_s = 0.250 \ g$

The molar mass of $Zn_{(s)}$ is a constant with value 65.39 g /mol

The molar mass of $S_{(s)}$ is a constant with value 32.01 g/mol

The molar mass of $ZnS_{(s)}$ is a constant with value 97.46 g/mol

The reaction is

$Zn_{(s)} + S_{(s)} ------> ZnS_{(s)}$

So from the reaction

1 mole of $Zn_{(s)}$ react with 1 mole of $S_{(s)}$ to produce 1 mole of $ZnS_{(s)}$

This implies that

65.39 g /mol of $Zn_{(s)}$ react with 32.01 g/mol of $S_{(s)}$ to produce 97.46 g/mol of $ZnS_{(s)}$

From the values given we can deduce that the limiting reactant is sulfur cause of the smaller mass

0.250 g of $Zn_{(s)}$ react with 0.250 of $S_{(s)}$ to produce $x \ g$ of $ZnS_{(s)}$

$x = \frac{97.46 * 0.250}{32.01}$

$x = 0.76 \ g$

Thus the mass of the mass of zinc sulfide produced is

$M_{ZnS} = 0.76 \ g$

A water skier is pulled by a net force of 165 N and has an acceleration of 2.2 m/s2. What is the mass of the skier?

TiliK225 [7]

A) 75 kg

Answer^

Explanation:

a = Fnet / m : plug the numbers in

2.2 m/s ^2 = 165n /m : now cross multiple

22m / 165 : now divide 22 to both sides

M = 75

In chemical reactions, kinetics is related to _______________, whereas thermodynamics is related to ___________________.

STALIN [3.7K]

Thermodynamics tells us what can occur during a process, while kinetics tell us what actually occurs.

<h3>What is Thermodynamics?</h3>

Thermodynamics is the branch of study that examines the possible states that material systems might take on and the potential changes in states that can arise either naturally or as a result of interactions between systems. The Greek terms thermé (heat) and dynamics were used to create the English phrase "thermodynamics" (force).

<h3>What is Kinetics?</h3>

Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is to be contrasted with thermodynamics, which deals with the direction in which a process occurs but in itself tells nothing about its rate.
