Answer:

<em>In the given question Brianna is trying to make a </em><em>whole figure by combining different  single elements.</em>

Explanation:

Here are the different  coloured that are used to join and make one piece this method that Brianna is following is called synthesis.

The combination here is of simple substances that are combined directly to make a complex compound. The compound formed is complex while the substances that combined together can be element or compound  or a combination of both.

How are ionic compounds named?<br><br>​
Dimas [21]

Answer:

Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions.

Explanation:

For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion.

What change would shift the equilibrium system to the left?
SVEN [57.7K]

Answer:

Adding more of gas C to the system

Explanation:

  • <em>Le Châtelier's principle</em><em> states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.</em>

1) Adding more of gas C to the system:

Adding more C gas will increase the concentration of the products side. So, the reaction will be shifted to the left to attain the equilibrium again.

2) Heating the system:

Heating the system will increase the concentration of the reactants side as the reaction is endothermic. so, the reaction will be shifted to the right to attain the equilibrium again.

3) Increasing the volume:

has no effect since the no. of moles of gases is the same in both reactants and products sides.

4) Removing some of gas C from the system:

Removing some of gas C from the system will decrease the concentration of the products side. So, the reaction will be shifted to the right to attain the equilibrium again.

<em>So, the right choice is: Adding more of gas C to the system.</em>

Calculate the molality of a 0.677 m ethanol ( c 2 h 5 o h ) solution whose density is 0.588 g/ml
ANEK [815]

The molality of a 0.677 m ethanol ( c 2 h 5 o h ) solution whose density is 0.588 g/ml.

What is molality and molarity?

The number of solvent moles per kilogram is known as molality. Because the mass of the solute and solvent in the solution remains constant, molality is the preferred concentration transfer method.

Molarity, also referred to as molar concentration, is the quantity of a material expressed as moles per litre of solution. Solutions marked with a molar concentration have a capital M. One mole of solvent per litre is present in a 1.0 M solution.

Molar mass (w) of C2H5OH = 46g

Molarity(M) = 0.677M

Density(D) = 0.588g/mol

<u>Molality(m)</u><u> = M/D * (1000 + w*M)</u>

<u>= 1187.2m</u>

To learn more about molality and molarity  from the given link below,
