The scientific method is "flexible". What does that mean? Why is that
important and necessary?

Answers

Answer:

we can reach the same conclusions by applying different experimental and observational procedures

Explanation:

The scientific method is a process that can be summarized in the following steps: 1-to raise a question, 2-to make a hypothesis, 3-to obtain data from observations and/or experiments, and finally, 4-to obtain conclusions that enable to confirm (or reject) the hypothesis. The scientific method is flexible because it is not necessary to follow 'stringent' guidelines in order to reach the same conclusions. In consequence, the predictions derived from such results can be tested again to determine the veracity of the results.

Bombardier beetles inject boiling hydrogen peroxide, or H2O2, into the victims. It then decomposes into hydrogen and oxygen gas. How many grams of oxygen can be produced if 0.128 grams of hydrogen peroxide are decomposed?

Answers

Answer:

0.12 g of O2.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

H2O2 —> H2 + O2

Next, we shall determine the mass of H2O2 that decomposed and the mass of O2 produced from the balanced equation. This is illustrated below:

Molar mass of H2O2 = (2×1) + (16×2)

= 2 + 32

= 34 g/mol

Mass of H2O2 from the balanced equation = 1 × 34 = 34 g.

Molar mass of O2 = 16×2 = 32 g/mol

Mass of O2 from the balanced equation = 1 × 32 = 32 g

Summary:

From the balanced equation above,

34 g of H2O2 decomposed to produce 32 g of O2.

Finally, we shall determine the mass of O2 produced from the decomposition of 0.128 g of H2O2. This can be obtained as follow:

From the balanced equation above,

34 g of H2O2 decomposed to produce 32 g of O2.

Therefore, 0.128 g of H2O2 will decompose to produce = (0.128×32)/34 = 0.12 g of O2.

Therefore, 0.12 g of O2 was produced.

1. Calculate the density of a liquid that has mass of 14.0g and volume of 18.0 cm? Will this liquid float on
top of water or will it sink? (Density of water is 1.0 g/mL)
I

Answers

formula for density of liquid = mass ÷ vol

= 14.0 g ÷ 18.0 cm³

= 0.77778 g/cm³ ( 5sf)

= 0.778 g/cm³ ( 3sf )

18.0 cm³ is the same as 18.0 ml

Therefore, the liquid will float on water as the water is denser than the liquid.

18.0 cm³ is equivalent to 18.0 ml, in light of the fact that water is denser than liquid, the liquid will float on it.

What is the density of a liquid?

Density is defined as d = M/V, where M stands for mass and V for volume. The unit of density that is most frequently used is grams per cubic centimeter.

The formula for liquid density is mass divided by volume.

= 14.0 g ÷ 18.0 cm³

= 0.77778 g/cm³

= 0.778 g/cm³

The same procedure used to determine a solid's density is used to determine a liquid's density. Calculate the fluid's mass, then its volume, then divide mass by volume.

To determine the fluid's mass, weigh the fluid in the container, pour it out, weigh the empty container, and then subtract the empty container's mass from the mass of the filled container.

Therefore, in light of the fact that water is denser than liquid, the liquid will float on it.

Answer:

Density = 3.9 g/ mL

Explanation:

The density of a substance can be found by using the formula

[tex]Density = \frac{mass}{volume} [/tex]

From the question

mass = 43 g

volume = 11.1 mL

Substitute the values into the above formula and solve for the density

That's

[tex]Density = \frac{43}{11.1} \\ = 3.873873...[/tex]

How many calories are required to convert 2 grams of ice at 0 degrees C to water vapor at 100 degrees C?

Answers

Answer:

360.8987 GRAM CALORIE OR 0.3608987 KILOCALORIE IS THE CALORIE REQUIRED TO CONVERT 2 GRAMS OF ICE AT 0 DEGREES C TO WATER VAPOUR AT 100 DEGREES C.

Explanation:

To convert 2 g of ice at 0 C to water vapor at 100 C:

First, the ice will be converted to water at 0 C

Then, water at 0 C to water vapor at 100 C

We must know that the latent heat of fusion for ice is 3.35*10^5 J/kg

the standard heat of enthalpy of water = 4200 J/kg

So therefore

Total heat to convert ice at 0 c to water vapor at 100 c is:

= M Lf + mc Q

= 2/ 1000 * 3.35 * 10^5 + 2/1000 * 4200 * (100 -0)

= 0.002 * 3.35 ^ 10^5 + 0.002 * 4200 * 100

= 0.0067 * 10 ^5 + 840

= 670 + 840

= 1510 J

The heat required to convert 2 g of ice at 0 c to water vapor at 100 C is 1510 J and to get the calorie value we divide the answer in joules by 4.184.

1510 joules = 360.8987 gram calories or 0.3608987 kilocalorie.

Amount calories are required to convert into vapor is 1,440 calories

Latent heat of water:

Given that;

Amount of ice = 2 grams

Latent heat of water = 540 calorie

Find:

Amount calories are required to convert into vapor

Computation;

Heat required to melt at 0°C to water at 0°C = 2 × 80

Heat required to melt at 0°C to water at 0°C = 160 calorie

Water from 0°C to 100°C = 2 × 100

Water from 0°C to 100°C = 200 calorie

Water from 100°C to 100°C vapor = 2 × 540

Water from 100°C to 100°C vapor = 1,080 calorie

Amount calories are required to convert into vapor = 160 + 200 + 1080

Amount calories are required to convert into vapor = 1,440 calories

What happens when an X-ray is shot at an atom

Answers

Answer: X-ray fluorescence from atoms occurs when a high energy particle or X-ray knocks an electron free from the innermost energy level of an atom, creating an unstable atom.

Explanation:

Several interactions can happen when an atom is exposed to an X-ray, depending on the energy of the X-ray and the properties of the atom.

The most frequent interaction is referred to as the photoelectric effect, in which an X-ray photon collides with an atom's inner-shell electron to evict it from its orbit and ionize the atom. As a result, an ion and a free electron are created. Another potential interaction is Compton scattering, in which an outer-shell electron receives some of the energy from the X-ray photon and is expelled at a different angle with less energy as a result. Additionally, pair production, which results in the formation of an electron-positron pair, can happen at very high energies. In many applications, these interactions are crucial.

Constants (“controlled variables”) and a control are easily confused by students! How would you explain the difference between the two words?

Answers

Answer:

Please find the explained difference below

Explanation:

In a scientific experiment, the CONTROLLED VARIABLE, also known as CONSTANT, is the the variable that is kept unchanged by the experimenter throughout the course of the experiment. The constants are not part of the actual experiment but altering them can influence its outcome.

A control group is one of the two groups in an experiment (the other being experimental group) that doesn't receive the variable being manipulated (independent variable). The control group is the same as the experimental group except that the independent variable is unchanged in the control group. It is used to make a comparison with the experimental group.

For example, in an experiment to test the effect of sunlight on plant growth. Some plants were exposed to sunlight while some were placed in the dark. The CONTROL group of this experiment are the plants placed in the dark (no light). They didn't receive any treatment.

The constants of this experiment can be same amount of water, same type of plants used etc. This is done in order not to affect the outcome of the experiment.
