Answer:

A) Solute

Explanation:

In forming a solution, the substance which is dissolved by the action of the solvent is called solute.

The formula unit equation for the given reaction occurring in water is

CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq).

Chemical reactions are those reaction in which reactant molecules react with each other for the formation of product.

When calcium sulfide reacts with iron (II) bromide for the formation of iron(II) sulfide and calcium bromide will be represented through the following equation:

CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq)

Above reaction best explains the formula unit of given reaction as all valency of atoms are satisfied there.

Hence, the required formula unit is CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq).

The new volume of the methane gas would be 113 atm

At constant temperature, the pressure of a gas is inversely proportional to its volume.

Mathematically; P1V1 = P2V2 where P1 = initial pressure, P2 = final pressure, V1 = initial temperature, and V2 - final temperature.

In this case, V1 = 226 [tex]cm^3[/tex],  P2 = 2P1

Thus: V2 = P1V1/2P1 = V1/2 = 226/2 = 113 atm

The solubility product of the substance MS in water is 2.0 * 10^-8.

The solubility product is an equilibrium constant that shows the extent to which a solid is dissolved in water.

In this case, the equilibrium is; MS(s) = M²+ (aq) + S²-(aq) but M²+ (aq)] = S^2-(aq)] = 0.000143 mol L-¹.

Thus

Ksp = [0.000143 ]^2 = 2.0 * 10^-8

Explanation:

Net ionic equations must be balanced by both mass and charge. Balancing by mass means ensuring that there are equal masses of each element on the product and reactant sides. Balancing by charge means making sure that the overall charge is the same on both sides of the equation.

Answer:

You can get to the answer in two steps:

calculate: 3.40⋅1022 atoms = x mol ?

using Avogadro's constant.

calculate: x mol = ? grams,

using the atomic mass of Helium.

Step 1

Avogadro's constant says that 1 mole of any atom contains 6.022⋅1023 atoms. In this case you have 3.40⋅1022 atoms:

3.40⋅1022atoms6.022⋅1023atomsmol = 5.65⋅10−2mol

Step 2

The atomic mass of helium (He) will give you the weight of one mole of this molecule: 1 mol = 4.00 gram:

4.00gmol⋅5.65⋅10−2mol = 0.226g

So the 3.40⋅1022 helium atoms weigh 0.226 gram.

Answer:

Structure 1:
The longest chain is made up of 4 carbons (butane). There is a 1-carbon branch (methyl). The lowest possible position of the branch is on the 2nd carbon. This makes the alkane: 2-methylbutane.

Structure 2:

The longest chain is made up of 7 carbons (heptane). There is a 2-carbon branch (ethyl). The lowest possible position of the branch is on the 4th carbon. This makes the alkane: 4-ethylheptane.

Structure 3:
The longest chain is made up of 4 carbons (butane). There are 2, 1-carbon branches (dimethyl). The lowest possible position of both branches is on the 2nd carbon. This makes the alkane: 2,2-dimethylbutane.

Structure 4:
The longest chain is made up of 3 carbons (propane). There are 2, 1-carbon branches (dimethyl). The lowest possible position of both branches is on the 2nd carbon. This makes the alkane: 2,2-dimethylpropane.

Structure 5:
The longest chain is made up of 6 carbons (hexane). There is a 1-carbon branch (methyl). The lowest possible position of the branch is on the 2nd carbon. This makes the alkane: 2-methylhexane.

Structure 6:
The longest chain is made up of 3 carbons (propane). There is a 1-carbon branch (methyl). The lowest possible position of the branch is on the 2nd carbon. This makes the alkane: 2-methylpropane.

The isomers are structures 1 and 4 because they contain the same amount of carbons (5) and hydrogens (12) while assuming different structures.

Answer:12668 J.

Explanation:

First of all, steam is there so in order to convert it into water it must have to release latent heat of vaporization which is equal to approximately 2450 kJ/kg or 2450 J/g.

So, the calculation is given below.

Heat released during conversion of steam at 100°C to water at 100°C= m*L

= 5*2450= 12250 J.

Heat released during conversion of water at 100°C to water at 80°C= m*Cp*(∆T)

= 5*4.18*20= 418 J.

So total heat released= 12668 J.

hope this helps:)!!!

The heat energy released or absorbed by a system can be calculated using calorimetric equation. The heat is released when 60.0 g of steam at 235°C is converted to water at 100°C is 33858 J or 338 KJ.

Calorimetry is an analytical tool used to determine the heat energy q absorbed or released in a reaction system. The calorimetric equation connecting mass of the reactant m, specific heat capacity c and temperature difference ΔT is related by the expression:

q = mcΔT.

The mass of steam is given 60 g and temperature difference is from 235 to 100 °C thus 135 °C and the specific heat capacity of  water or steam is 4.18 J/°C. The heat energy released is calculated as follows:

q = 60 g × 4.18 J/°C × 135 °C

  = 33858 J

Hence, heat is released when 60.0 g of steam at 235°C is converted to water at 100°C is 33585 J.

Answer:

Nitrous Oxide

Explanation:

The Gibbs free energy describes the spontaneity of the chemical reaction. The reaction involving nitroglycerine is spontaneous.

Spontaneity is the condition of the reaction that continuously makes the product without adding input energy again and again. It is determined by the Gibbs free energy of the system.

When the Gibbs free energy of the thermodynamic system is negative then the reaction is said to be exothermic and is a spontaneous reaction. The negative Gibbs free energy of nitroglycerine at 273 K shows spontaneity.

Therefore, the reaction is spontaneous.
