An empirical research method in which data are gathered from observations of phenomena, hypothesis are formulated and tested, an

ahrayia [7]

Answer:

Scientific Method

Explanation:

Science is empirical in nature. The entire purpose of science is to discover new knowledge.

The empirical research method in science all begins with gathering observations from phenomena. After that, the researcher formulates appropriate hypothesis which are rigorously tested.

The conclusions drawn from testing the original hypothesis validate or modify the original hypothesis.

Given the following balanced equation, determine the rate of reaction with respect to [SO3]. If the rate of O2 loss is 3.56 x 10

Olenka [21]

Answer:

7.12 × 10⁻³ M/s

Explanation:

Step 1: Write the balanced reaction

2 SO₂ + O₂ ⇒ 2 SO₃

Step 2: Establish the appropriate molar ratio

According to the balanced equation, the molar ratio of O₂ to SO₃ is 1:2.

Step 3: Calculate the rate of formation of SO₃

The rate of loss of O₂ is 3.56 × 10⁻³ mol O₂/L.s. The rate of formation of SO₃ is:

3.56 × 10⁻³ mol O₂/L.s. × 2 mol SO₃/1 mol O₂ = 7.12 × 10⁻³ mol SO₃/L.s

A solution of HCl gas dissolved in water (sold commercially as "muriatic acid," a solution used to clean masonry surfaces) has 2

disa [49]

Answer:

[HCl] = 6.09 M

Xm HCl = 0.11

Explanation:

Let's analyse data:

20.22 g of solute / 100 g of solution

Solution's density = 1.10 g/mL

As we have the mass of solution and its density we determine solution's volume to stablish [M]

Density = Mass / volume → 1.10 g/mL = 100 g / Volume

100 g / 1.10g/mL = 90.9 mL

Let's convert the volume to L → 90.9 mL . 1L/ 1000mL = 0.0909L

We convert the mass of solute to moles → 20.22 g . 1mol/ 36.45g =

0.554 moles

[M] = Molarity (moles of solute /1L of solution) = 0.554 mol/0.0909L = 6.09M

Mole fraction (Xm) = Moles of solute / Total moles

Total moles = Moles of solute + Moles of solvent

Mass of solvent = Mass of solution - Mass of solute

Mass of solvent = 100 g - 20.22 g = 79.78g

We convert the mass to moles → 79.78 g / 18g/mol = 4.43 moles

Total moles = 4.43 moles + 0.554moles = 4.984 moles

Xm = 0.554 / 4.984 = 0.11

Getting these when you’re young helps your immune system fight off diseases:

Brilliant_brown [7]

C

Immunization shots are given to ensure immunity against future attacks on the body against the disease in which the vaccine is made.

Explanation:

The vaccine prepares the body by giving immune cells memory against the disease agent. The vaccine achieves this by introducing an attenuated form of the agent of the disease into the body. This means the introduced disease agents cannot cause disease but are enough to evoke an immune response from the body. The immune system, after eradicating the attenuated disease agent from the body, acquires memory such that it fights a real-world disease agent in case of infection.
