The mass of a coin : 2.2613 g

<h3>Further explanation  </h3>

Algebraic expressions in mathematics are a combination of coefficients, numbers, variables, constants and arithmetic operations such as addition, subtraction, multiplication, and division.  

The main composition of algebraic expressions are:  

  • 1. phrases  

algebraic forms separated by arithmetic operations  

consists of one phrase (monomial) to many phrases (polynomial)  

  • 2. variables  

is a value that can be changed, can be in the form of letters, for example, x, y, a, b, etc.  

  • 3. constants  

is a fixed value, can be a number  

  • 4. arithmetic operations ⇒ +, - , : , x

<em>If 100 coins have a total mass of 226.13g. What is the mass of a coin</em>

We can make this statement in the form of an algebraic equation :

100 coins=226.13 g

then the mass of a coin :

\tt \dfrac{1}{100}\times 226.13~g=2.2613~g

If a chemical reaction goes to completion, what can we say about the equilibrium constant for that reaction?
aniked [119]

Answer:

A. The equilibrium constant is very large

Explanation:

The equilibrium constant value is the ratio of the concentrations of the products over the reactants. When a chemical reaction goes to completion, that means that all the reactant has turned into products. As the equilibrium constant defines, it is the ratio of the product to the reactant. So at the final stage of the chemical reaction, the equilibrium constant will be very large.

Chemistry Question, Don't really know how to do it lol.
Scilla [17]

Answer: 17.2 g

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}

\text{Moles of} HgS=\frac{20.0 g}{233g/mol}=0.085moles

The balanced chemical equation is:

4HgS(s)+4CaO(s)\rightarrow 4Hg(l)+3CaS(s))+CaSO_4(s)  

According to stoichiometry :  

4 moles of HgS produce =  4 moles of Hg

Thus 0.085 moles of HgS will require=\frac{4}{4}\times 0.085=0.085moles  of Hg

Mass of Hg=moles\times {\text {Molar mass}}=0.085moles\times 200.6g/mol=17.2g

Thus 17.2 g of Hg will be produced form 20.0 g of HgS.
