By referring to the particulate theory of mater, explain the following statement: Oxygen gas is very easy to compress when pressure is applied​

By referring to the particulate theory of matter, explain the following statement: A solid lump of iron has a high density​ .​

Answers

Answer 1

Answer:

See explanation

Explanation:

According to the particulate theory of matter, gas particles do not interact with each other. A gas is composed of isolated particles moving at high velocities and collide frequently with each other and the walls of the container.

Since the particles of a gas are mostly isolated, it is easy to compress the gas when pressure is applied thereby bringing the gas particles closer together.

On the other hand, in the solid state, the particles that compose matter are close together. These particles only vibrate about their mean positions due to strong intermolecular interaction between particles. The fact that the particles of the solid ion are so close together makes the solid iron lump to possess high density.

Silicon dioxide reacts with carbon to form silicon carbide and carbon monoxide as shown in the unbalanced reaction below. Determine the percent yield of silicon carbide if 79.1 grams of carbon reacts with an excess of silicon dioxide and 67.4 g of silicon carbide is actually recovered.
SiO2 + C → SiC + CO

Answers

Excess silicon dioxide" tells us carbon is the limiting reactant, and thus the amount of silicon carbide produced depends on how much carbon is available to react.
*Based on the balanced equation, for every 3 moles carbon reacted, 1 mole silicon carbide is produced.
*Molar mass carbon: 12.01 g/mol
*Molar mass silicon carbide: 28.09 g + 12.01 g = 40.1 g/mol

79.1 g carbon x (1 mol carbon / 12.01 g carbon) x (1 mol silicon carbide / 3 mol carbon) x (40.1 g silicon carbide / 1 mol silicon carbide) = 88.04 g silicon carbide

The number of atoms in a mole is always equal to Avogadro's constant, which is 6.02214076×10²³ mol⁻¹.

To find the number of atoms in 0.490 moles of barium, multiply it with Avogadro's constant:

0.490 mol * 6.02214076×10²³ mol⁻¹ ≈ 2.9508 * 10^23

sulfur and oxygen can react to form both sulfur dioxide and sulfur trioxide in sulfur dioxide there are 32.06 grams of sulfur and 32 grams of oxygen in sulfur dioxide there are 32.06 grams of sulfur are combined with 48 grams of oxygen

a. what is the ratio of the weights of oxygen that combine with 32.06 g of sulfur ?
b. How do these data illustrate the law of multiple proportions? ​

Answers

Answer:

Explanation:

In sulfur dioxide there are 32.06 grams of sulfur and 32 grams of oxygen .

In sulfur trioxide there are 32.06 grams of sulfur are combined with 48 grams of oxygen.

The ratio of oxygen which reacts with 32.06 gram of sulfur is 32: 48 .

This ratio is equal to 2 : 3.

This is in accordance with law of multiple proportion because , the ratio of mass of oxygen which reacts with constant mass of sulfur is integral ratio . Hence they are in accordance with law of multiple proportions.

Answer:

sulfur and oxygen can react to form both sulfur dioxide and sulfur trioxide in sulfur dioxide there are 32.06 grams of sulfur and 32 grams of oxygen in sulfur dioxide there are 32.06 grams of sulfur are combined with 48 grams of oxygen

a. what is the ratio of the weights of oxygen that combine with 32.06 g of sulfur?

b. How do these data illustrate the law of multiple proportions? ​

Explanation:

In sulfur dioxide ([tex]SO_2[/tex])

32.06 g of sulfur reacts with 32.0 g of oxygen.

In sulfur trioxide ([tex](SO_3)[/tex] 32.0 g of sulfur reacts with 48.0 g of oxygen.

So, both th ecom[pounds are made from sulfur and oxygen,

But the amount of oxygen reacts with fixed amount of sulfur that is 32.06 g and it is in proportions that is:

32.0 g : 48.0 g

=2:3.

Hence, the ratio of oxygen combines with sulfur is in the ratio of 2:3.

b.

This data illustrates the law of multiple proportions.

Because the oxygen which is combining with fixed amount of sulfur is in proportions.

Write a report on the implications of entropy to a Christian 500 words

Answers

The universe is "running down," becoming randomly scattered and disorganized, tending to break down into its simple parts. Metals rust, parts wear out, dead organisms decay and turn to dust. The entropy of the universe is increasing.

The Bible provides an answer. A great amount of energy had to be expended to produce such great organization. As one scientist states the problem, energy was not enough. If you are asked to "reduce the entropy" of your room (put it in order), you certainly need to put in some effort (energy). But just adding energy is not enough. You could let loose a bull in your room, and it would expend a great deal of energy; however, that energy would not decrease but would increase the disorder of the room. Therefore, scientists know that to produce order, energy must be intelligently directed. Evolution requires that atoms and molecules assemble themselves into increasing order, but the science of thermodynamics assures us that the entire universe, when left to itself, is converting to disorder. The Apostle Paul referred to this concept when he said through inspiration that the entire earth is "subject to the bondage of decay." The original state required an intelligence to organize the complexities of the universe.

Christians, of course, have an answer to these perplexing questions: God. God is the Creator of the universe, the ultimate source of its energy and order. He created it with no entropy (no disorder). When man sinned, the universe began to increase in entropy (become more and more disordered). For Christians a discussion of energy, thermodynamics, and entropy is inspiring. These subjects invariably point us to the One who created the universe and sustains it by His power. Christians also know that His power will one day totally renew the universe and entropy will have no part in it.

Christians need never be afraid of science. God is in control of the universe and all the laws of the universe operate according to His will and design. Christians should be confident that they have the answers to the perplexing questions of nature.

Part 2

The above attitude allows christians to ignore questions that are difficult and this leads to mental complacency.

"This is gods work. I must not question or touch this". Is their motto.

When christians see difficult questions, such as entropy and creation, that is where they stop thinking and attribute it to god. They become intellectually crippled and refuse to make that one further step. It then halts progress until the shamen can integrate new knowledge into their mantra and dogma.

Science in general, tries to explain and understand and make further progress and additions to human knowledge. Christians will only try to understand what they have been taught and integrate any new knowledge when the older beliefs become untenable.

Household ammonia has a pH of 12; household bleach has a pH of 13. Which of the following statements about these substances is true? Group of answer choices The ammonia has 10 times as many OH- ions as the bleach. The ammonia has 10 times as many H+ ions as the bleach. A solution that could buffer the bleach and ammonia would remove excess OH- ions. Both of these substances are strong acids.

Answers

Answer:

The ammonia has 10 times as many H+ ions as the bleach.

Explanation:

pH is defined as -log[H+]

[H+] of ammonia is = 10^-12 = 1x10-12M

Bleach = 1x10-13M

pOH = 14-pH = 2 for ammonia and 1 for bleach

[OH-] = 10^-pOH = 0.01M for ammonia and 0.1M for bleach

Thus:

The ammonia has 10 times as many OH- ions as the bleach. FALSE.

The ammonia has 10 times as many H+ ions as the bleach. TRUE.

A solution that could buffer the bleach and ammonia would remove excess OH- ions. FALSE. A buffer maintains OH- ion concentration

Both of these substances are strong acids. FALSE. Strong acids have pHs < 7
