you are going to measure the conductivity of the analyte beaker during a titration. initially, the beaker contains only aqueous mgcl2, which fully dissolves in water. generally, how many ions does each molecule of mgcl2 break into? group of answer choices
Each magnesium chloride (MgCl₂) molecule dissociates into 3 ions in total.
Magnesium chloride (MgCl₂) is a salt which means that, upon dissolving in water, it will dissociate, giving positively charged metal cations (here, magnesium ions) and negatively charged anions formed from nonmetals (here, chloride ions). The balanced reaction equation for magnesium chloride (MgCl₂) dissociation looks like this:
MgCl₂(aq) → Mg²⁺(aq) + 2Cl⁻(aq)
We can see that, upon dissociation, each molecule of magnesium chloride forms a single magnesium ion (Mg²⁺) and two chloride ions (Cl⁻). So, in total, 1 + 2 = 3 ions are formed from each unit of magnesium chloride.

how does hydrogenation affect unsaturated fats? a. it changes them so they are more water-soluble. b. it changes solid fats to trans fatty acids. c. it changes them to polyunsaturated fats as it removes hydrogen atoms. d. it adds antioxidants to them, creating a better-preserved product. e. it adds hydrogen atoms to their chains, making them more saturated.
Hydrogenation affects unsaturated fats by adding hydrogen atoms to their unsaturated chains and making them be more saturated.
What is unsaturation?Unsaturation in organic compounds is an indication of the presence of double or triple bonds in one or more C-C bonds in the structure of the compounds.
Saturated organic compounds do not have double or triple C-C bonds in them.
Unsaturated compounds, therefore, have the tendency to undergo addition reactions due to the presence of the double/triple bond.
Hydrogenation of unsaturated fats is an additional reaction. The hydrogen atoms attach themselves by pairing with the lone electron pairs in the double or triple bonds.
Thus, the addition of hydrogen makes unsaturated compounds to be more saturated.
Saturated compounds, on the other hand, can only undergo substitution reactions instead of addition reactions.

The four main components of a modern detergent are builders (50% by weight), surfactants (15%), bleach (7%), and enzymes (2%).
What is the use of the components in the detergent?A detergent can be described as a surfactant or a mixture of surfactants with cleansing properties in dilute solutions. These substances are similar to soap but are more soluble in hard water due to the polar sulfonate is less likely than the polar carboxylate of soap to bind ions in hard water.
Builders are water softeners and their anions react with cations to form insoluble compounds which precipitate onto fabrics and washing machines and which are hard to remove.
Surfactants provide absorption and emulsification of soil into the water and also by reducing the surface tension of water to improve wetting. The main function of bleaches is oxidizable organic stains, which are usually of vegetable origin.

which of the following will increase the rate of a chemical reaction? increase the temperature at which the reaction occurs. allow the reaction to proceed for a longer time. decrease the concentrations of the reactants. decrease the amount of time in which the reaction is allowed to occur. decrease the temperature at which the reaction occurs.
Option C is correct. reduce reactant concentrations. shorten the time the reaction is allowed to proceed.
The reaction rate normally increases as the temperature rises. With rising temperature, the average kinetic energy of the reactant molecules rises. The minimum energy needed for an effective collision will therefore be present in a higher percentage of molecules. With rising temperatures, molecules' kinetic energy rises. The possibility of a reaction rises as molecules move more quickly and collide more frequently. This speeds up the reaction. The average kinetic energy of the individual particles of the system increases with increasing temperature. Particles move faster and collide more often per unit time as the average kinetic energy increases, and they have more energy when they collide. Both of these factors speed up the reaction.

How many grams of sodium fluoride are needed to prepare a 0.600m NaF solution that contains 600.0 g of water? Show your work.
Molality (W) is the ratio of the amount of substance of a solute (in moles – n) to the mass in kilograms of the solvent (m1). It can be calculated by the following formula:
W = n/m1
Step 1 - Let's discover how many moles of sodium fluoride is needed first.
Let's transform 600 g of water to kilograms:
1 g = 0.001 kg
600 g = 0.6 kg
W = 0.600m
m1 = 0.6
0.600 = n/0.6
n = 0.36 moles of sodium floride
Step 2 - Let's transform 0.36 moles of NaF into grams. Let's use the following formula: mass = moles x molar mass
molar mass of NaF = 42 g/mol
mass = 0.36 x 42
mass = 15.12 g
Answer: 15.12 g of NaF

Calculate the root mean square velocity for the atoms in a sample of helium gas at 25°C
The gas constant is equal to R=8.314 J/mol K, while the atomic mass of helium is equal to M=4.0 g/mol. M = 4.0 g / m o l . As a result, the helium atom's rms speed is 1304.7 m/s. So, 515 m/sec is the root-mean-square speed.
What is root mean square velocity?The value of the square root of the sum of the squares of the stacking velocity values divided by the quantity of values is the root-mean square (RMS) velocity. The RMS velocity is the speed of a wave traveling along a certain ray path across subsurface strata with various interval velocities.
The expression v=sqrt(3RTM) and v=sqrt(3KTm), where R is the universal gas constant, T is the absolute (Kelvin) temperature, m is the molar mass, K is the Boltzmann's constant, and M is the molecular mass, gives the root mean square (R.M.S.) speed V of the molecules of an ideal gas.
Since the particles in a typical gas sample are flowing in all directions, the average velocity for that sample is zero, which is why we use the rms velocity instead of the average. This is an important formula since the particle velocity controls both the diffusion and effusion rates.

A waste management specialist for a city is designing a recycling program to reduce the amount of synthetic materials that enter the local landfill. Which of the following criteria would be best for the specialist's design? A. to make it easy for the residents of the city to recycle synthetic materials B. to keep anything made of natural materials from entering the landfill C. to make residents travel a long distance to recycle synthetic materials D. to keep residents from using anything made of synthetic materials
Option A would be the right recycling program to reduce the number of synthetic materials that enter the local landfill. Hence option A would be the suitable criteria for the specialist's design.
Option A is correct because, with the providence of the knowledge to recycle synthetic materials, there will be less waste accumulation. Hence most synthetic materials can be expected to be recycled.
Option B is wrong because restricting natural materials from entering the field will further increase the use of synthetic materials. Hence there will be more accumulation of waste.
Option C is wrong because making the residents travel long distances will be tiresome, and the outcome of disposing of them will be little.
Option D is wrong because synthetic materials are valuable in various manufacturing and widely used in our daily lives. Hence we will lose the potential benefits.
