Answer:
C2H4(g) + Cl2(g)→C2H4Cl2(g)
This is an example of synthesis reaction, when compounds are joined together.
Calculate the percent composition by mass of each element in NaClO2.
Answer: Divide the mass of the first dissolved component by the solution mass, and then multiply the result by 100 to calculate the mass percentage. In our example, the first dissolved compound is NaCl; the mass percent is (10 g / 136 g) x 100 percent = 7.35 percent.

How can a charged balloon attract a wall without any contact?
The positive charges of the uncharged wall move to the outside.
The wall changes shape and the positive charges move to the inside.
The negatively charged balloon repels and moves away from the wall.
A positive charge in the balloon attracts the negative charges in the wall
Answer:
A positive charge in the balloon attracts the negative charges in the wall
Explanation:
The question states attract, so we know it's not going to be option C.
The wall clearly doesn't change shape, so that eliminates option B as well.
The balloon gets positively charged, and so for an attractive force to appear, you need the opposite charge from the wall, i.e. negative.
Remember: opposite charges attract
Which means, the only option that makes sense is Option D.
P.S.: You could've concluded it's option D just because it's the only one that contains the word "attract" in there!
Hope I helped! :)
Answer:
a positive charge in the ballon attract the negative charge of the wall
Explanation:
how can you tell whether a substance is a binary compound
Given what we know, we can confirm that a compound will be a binary compound if it contains both a metal and a non-metal element.
Why does this combination form binary compounds?The reason for this is that metals will be able to donate electrons thanks to their chemical properties. Meanwhile, non-metal elements will seek to receive electrons to become more stable.For these reasons, metals and non-metals will come together to create covalent bonds, and thus, binary compounds.Therefore we can confirm that since a metal will donate its electron to a non-metal element to form covalent bonds, we will know if the compound is binary or not based on the presence of a metal and a non-metal.

in the reaction of aluminum metal and oxygen gas to make aluminum oxide, how many moles of aluminum will react with 0.80 grams o2?
Answer:
When 6.38 moles of O2 and 9.15 moles of Al react, the ratio of aluminum to oxygen is 9.15/6.38 = 1.434. This shows that all of the oxygen is consumed before the aluminum and when the reaction ends the reactant aluminum is left. The number of moles of Al2O3 formed is approximately 4.25 moles.

Why do you think the term ionic is used to describe compounds formed from a metal element and a nonmetal element?
Answer:
All compounds form when atoms of different elements share or transfer electrons. Compounds in which electrons are transferred from one atom to another are called ionic compounds.
Explanation:
Because the positive and negative charges cancel out, an ionic compound is neutral in charge.
why is stability of compounds essential
Answer:
chemical stability is important to consider in the comprehensive assessment of pharmaceutical properties, activity, and selectivity during drug discovery.
Answer:
In general, molecules are stable because all their constituent atoms have sufficient "valence" electrons-that is, electrons that participate in chemical bonding. Such electrons reside in the outer, or valence, "shell," which must fill up with the appropriate number of electrons for the bound atoms to be come stable.

how many molecules of butane are contained in 25.0 ml of butane? the density of butane is 0.6011 g/ml and the molar mass is 58.12 g/mol.
Explanation:
To determine the molecules of butane we can either use multiple steps or use a combined equation based on the following formulas:
Molecules of butane = Moles × Avogadro's Number
Moles of Butane = Mass ÷ Molar Mass
Mass of Butane = volume × Density
∴ Molecules of butane
= [(volume × Density) ÷ Molar Mass] × Avogadro's Number
= ([(25.0 ml × 0.6011 g/ml) ÷ 58.12 g/mol] × (6.022 × 10²³ molecules/mol))
= 1.557 × 10²³ molecules
∴ 25.0 ml of butane of density of 0.6011 g/ml contains 1.557 × 10²³ molecules.what is the amount of heat required to completely melt a 200
People who have certain lung diseases, such as emphysema or lung cancer, often have to use oxygen from tanks. A large volume of oxygen can be put into a small tank because oxygen is a gas, and gases can be_________.
Answer:
I believe the answer is compressed
Explanation:
The answer may be a slightly different word, but if it's looked at by a human and not a robot compressed should work too
Gases can be compressed by applying high pressure. Thus large volume of oxygen can be contained in a tank by compressing the gas with high pressure.
What are gases?Gases are substances in state where its molecules are located far apart and are able to spread in the surroundings. This property of spreading based on the concentration difference is called diffusion.
Thus, gases diffuse from high concentrated area to lower concentration region. Gaseous substances does not have a certain volume, mass or shape. But when they are collected into a container then the volume will be that of the container.
in liquid state, molecules are some more closer in comparison to gases and an intermolecular attraction of force bind these molecules together to have a certain volume and mass. Whereas in solids, all the molecules are tightly packed.
Gases can be liquified by applying high pressure at low temperature so that the distance between molecules can be decreased and an intermolecular force of attraction occurs there.
So that large volume of gases can be collected to a tank by compression using high pressure.
