give me 4 reason why Lab safety was important!​

Answers

Answer 1

Answer:

industrial lab safety, therefore, is critical to safeguard the health and well-being of these technicians, as is the protection of equipment, products, samples, supplies and the facility itself. The importance of testing lab safety cannot be overstated; it helps keep all of these components — most notably, workers — out of danger.

Safety is important in middle-school and high-school science labs to ensure students and teachers stay out of harm's way. Science classrooms often have equipment -- such as Bunsen burners, chemicals and sharp tools -- that pose potential hazards if used improperly. Teachers and school administrators don't have the time or the budget to deal with liability lawsuits, and dangerous incidents could damage the school's and the teacher's reputation.

Insulin is a protein composed of  chains, an a series with 21 amino acids and a B chain with 30 amino acids which are related together by using sulfur atoms. Insulin is derived from a seventy four-amino-acid prohormone molecule referred to as proinsulin.

The primary reason of insulin is to regulate the body's power deliver via balancing micronutrient stages throughout food intake 30. Insulin is crucial for transporting intracellular glucose to insulin-based mobile tissues together with the liver, muscle, and adipose tissue.

Insulin facilitates preserve blood sugar levels inside regular limits. It does this by means of taking glucose from the bloodstream and transporting it to the body's cells. Cells use glucose for strength and shop excess inside the liver, muscle, and adipose tissue.

Insulin offers cells with glucose for strength via reducing the frame's blood sugar levels and helping cells take in glucose. whilst blood sugar is too low, the pancreas releases glucagon.

Mole is the mass of a substance that contains 6.023 x 10²³ particles of the substance1 mol of Carbon-12 has mass of 12 grams and contains 6.022 x 10²³ of carbon atomsAtomic mass of nitrogen is 14u . A nitrogen molecule has 2 atoms of nitrogen. Thus its molecular mass is 14 × 2 = 28u.Molar mass is the mass of 1 mole of molecules i.e. mass of 6.022 × 10²³ molecules. Its the same number as molecular mass but the unit is in gramsWe can use the simple formula

                  n = w / M

        where

 n = no of moles = .65

w = Mass of the given sample = ?

M = Molar mass ( Molar mass is same as molecular mass) = 28g

     substituting the values

              n = w / M

              w = n × M

A large balloon is initially filled to a volume of 11.2 L at 325 K and a pressure of 3450 mm Hg. What volume of gas will the balloon contain at 1.4 atm and 325 K?

Answers

Answer:

36 L

Explanation:

Since the temperature remains constant, you can use Boyle's Law to find the final volume:

P₁V₁ = P₂V₂

In this formula, "P₁" and "V₁" represent the initial pressure and volume. "P₂" and "V₂" represent the final pressure and volume. Before, you can plug the given values into the equation and solve for "V₂", you need to convert mmHg to atm to maintain consistent units.

760 mmHg = 1 atm

P₁ = 3,450 mmHg / 760 mmHg = 4.54 atm      P₂ = 1.4 atm

V₁ = 11.2 L                                                            V₂ = ? L

P₁V₁ = P₂V₂                                                  <----- Boyle's Law

(4.54 atm)(11.2 L) = (1.4 atm)V₂                    <----- Insert values

50.848 = (1.4 atm)V₂                                   <----- Multiply 4.54 and 11.2

36 = V₂                                                        <----- Divide both sides by 1.4

Why is it important to have only one independent variable and to control the

Answers

Scientists cannot pinpoint the changes or variations in the results to a single source when more than one variable is altered during an experiment. The outcomes can be attributed to the independent variable directly by examining and modifying each variable separately.

You can evaluate the outcomes of your experiment to determine how much one adjustment impacted the outcome by testing just one variable at a time. You won't be able to identify the variable that caused the outcome if you're testing two variables simultaneously. A controlled variable is one that is kept constant with the goal of not affecting how an experiment turns out. Controlling any factors that can affect an experiment's outcomes allows us to be certain that the altered variable is what caused our results.

Calculate the number of moles of each substance.

Answers

Considering the definition of molar mass, the number of moles of Ti and Fe₂O₃ are 0.087 moles and 0.11 moles respectively.

Definition of molar mass

The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

The molar mass of a compound is the sum of the molar mass of the elements that form it (whose value is found in the periodic table) multiplied by the number of times they appear in the compound.

Molar mass of Ti

The molar mass of Ti is 204.37 g/mole.

Molar mass of Fe₂O₃

You know the molar mass of the elements is:

Fe= 55.85 g/moleO= 16 g/mole

So, the molar mass of the compound Fe₂O₃ is calculated as:

Fe₂O₃= 2× 55.85 g/mole + 3× 16 g/mole

Solving:

Fe₂O₃= 159.7 g/mole

Number of moles of each substance

You can apply the following rules of three:

If by definition of molar mass 204.37 grams of Ti are contained in 1 mole, 17.8 grams of Ti are contained in how many moles of Ti?

moles of Ti= (17.8 grams× 1 mole)÷ 204.37 grams

moles of Ti= 0.087 moles

If by definition of molar mass 159.7 grams of Fe₂O₃ are contained in 1 mole, 17.8 grams of Fe₂O₃ are contained in how many moles of Fe₂O₃?

moles of Fe₂O₃= (17.8 grams× 1 mole)÷ 159.7 grams

moles of Fe₂O₃= 0.11 moles

Finally, the number of moles of Ti and Fe₂O₃ are 0.087 moles and 0.11 moles respectively.

To make a stock solution, weigh out the proper amount of a pure solid or measure out the proper amount of a pure liquid, put it in the right flask, and then dilute it to the desired volume. Depending on the intended concentration unit, many methods can be used to measure the reagent.

If you take a 13.0- mL portion of the stock solution and dilute it to a total volume of 0.650 L , what will be the concentration of the final solution?

"The final solution's concentration would be 0.26M."

By adding extra solvent, you are lowering the concentration of the stock solution in the issue (This process is known as dilution).

Since you increased the volume of the fluid from 13 to 650 milliliters, it was diluted:

50 times = 650 mL / 13 mL

Select the statement that accurately summarizes how heat energy spreads throughout a substance. A) As a particle is heated, it absorbs energy. As it bumps into a nearby particle, it transfers all of the heat energy to the second particle. This leaves the first particle with no energy, so its movement slows.B) Heated particles absorb the energy and begin to move more and faster. As they move around, they bump into nearby particles and transfer some of their energy to those particles. This continues until all of the particles in the substance have the same amount of energy. C)Particles are heated and move around. They transfer thermal energy to the other particles as they bump into each other. This continues until all the particles lose all of their energy and motion stops. D)When particles are heated, they become sluggish and slow down. They transfer energy to nearby particles causing them to slow down, too.​

The statement " Heated particles absorb the energy and begin to move more and faster. As they move around, they bump into nearby particles and transfer some of their energy to those particles. This continues until all of the particles in the substance have the same amount of energy " summarises the heat transfer throughout the substance.

Heat is the thermal energy that is transferred from a system to its environment or from one thing to another. The object with the higher temperature is transferring energy to the thing with the lower temperature.In order to move thermal energy from one thing or thing to another, or from a system to its surroundings, there are three possible methods:ConductionConvectionRadiation The energy of the particles increases when energy is transmitted to an object. This indicates that the particles have higher kinetic energy, which causes them to move and vibrate more fastly. As the particles move more fastly, they "bump" into nearby particles and transfer some of their energy with them. In this manner, the substance at the other end receives the energy.

This is how energy is transferred in a substance.
