Answer: Magnesium Chloride $(MgCl_2)$ is produced other than hydrogen gas in the following reaction.

Explanation:

The given reaction is a type of single displacement reaction. This reaction is defined as the reaction in which a more reactive metal displaces a less reactive metal in a chemical reaction.

For the reaction of magnesium and hydrochloric acid, magnesium metal is more reactive than hydrogen, so it will easily displace hydrogen from its chemical reaction.

The equation follows:

$Mg(s)+2HCl(aq)\rightarrow MgCl_2(aq)+H_2(g)$

By Stoichiometry,

1 mole of magnesium metal reacts with 2 moles of hydrochloric acid to produce 1 mole of magnesium chloride and hydrogen gas.

Hence, the other product formed in the given reaction is magnesium chloride.

Suppose a system of two particles, represented by circles, have the possibility of occupying energy states with 0, 10, or 20 J.

MrMuchimi

Answer:

Explanation:

The possible energy states for the particles are 0, 10 and 20 J.

The constraint in the system is that the total energy of the particles must be 20 J.

One given configuration where the total energy is 20 J is if both the particles occupy the 10 J state.

Hence, (10;10) is the given configuration.

Another possibility is if one of the particle is in 0 J state and another is in 20 J state. Hence, the system has a total energy of 0+20 = 20 J.

Hence, the possible configuration can be written as (0;20) or (20;0) which are energetically equivalent to the given configuration. Note that if the circles are indistinguishable, then the configuration (0,20) and (20,0) is the same thing.

Calculate the mass % of K in potassium phosphate

Blizzard [7]

Answer:

$\large \boxed{\mathbf{1. \, \,55.26 \, \%; \, \,2. \, \,30.15 \, \% }}$

Explanation:

1. Mass percent of K

$\begin{array}{cccr}\mathbf{Atoms} & \textbf{Contribution} & & \textbf{Subtotal}\\\text{3K} & 3 \times 39.10 & = & 117.30\\\text{1P} & 1 \times 30.97 & = & 30.97\\\text{4O} & 4 \times 16.00 & = &64.00\\& \text{TOTAL} & = & \mathbf{212.27}\\\end{array}$

$\text{Percent K} = \dfrac{\text{117.30 g}}{\text{212.27 g}} \times \, 100\% = \mathbf{55.26 \, \%}\\\text{The percent by mass of potassium is $\large \boxed{\mathbf{55.26 \, \% }}$}$

2. Mass percent of O

$\text{Percent O} = \dfrac{\text{64.00 g}}{\text{212.27 g}} \times \, 100\% = \mathbf{30.15 \, \%}\\\text{The percent by mass of oxygen is $\large \boxed{\mathbf{30.15 \, \% }}$}$
