What occurs when a solid substance dissolves into a liquid? 1 It stays solid and sinks to the bottom of the liquid substance. 2 It breaks down and becomes part of the liquid substance. 3 It stays solid and floats on the top of the liquid substance. 4 It changes the liquid substance into a solid substance.
Explanation:
When a solid substance is dissolved in a liquid such as water, the intermolecular forces of attraction between the molecules in the solid substance are overcome and they exist as ions in the solution. Hence the answer is 2.
The correct option is 2.
When a solid substance is dissolved in a liquid such as water, the intermolecular forces of attraction between the molecules in the solid substance are overcome and they exist as ions in the solution.
What is dissolution?Dissolution is the process in which a substance forms a solution. Dissolution testing measures the extent and rate of solution formation from a dosage form, such as a tablet, capsule, ointment, etc. The dissolution of a drug is important for its bioavailability and therapeutic effectiveness.
What is an example of a dissolution?Stirring sugar into water is an example of dissolving. The sugar is the solute, while the water is the solvent. Dissolving salt in water is an example of the dissolution of an ionic compound.

Calculate 1.23 m x 0.89 m and give your answer with the correct number of significant figures?
Answer:
1.1m that what I got and it said it was right
The calculation of the given figure to one significant figure is[tex]1.1 m^{2}[/tex]
Significant figures can be regarded as a number of digits that is present in a particular value.Given 1.23 mAnd 0.89 m
If we multiply we have[tex]( 1.23*0.89) = 1.0947[/tex]
Since, there is no definite significant figure given, I will assume one significant figure.To do this we start to count significant figures starting from first non-zero digit to the actual figure we are requested to stop.We can see that 9 is after zero, the we round off that 9 then it will become 1 , Then the value to one significant figure is [tex]1.1m^{2}[/tex]Therefore, the multiplication of the values to one significant figure is [tex]1.1^{2}[/tex]

A gas has a volume of 150 cm3. Convert this volume into mL
Answer:
The answer is
150 mLExplanation:
To convert the volume from cm³ to mL we use the conversion
1 cm³ = 1 mL
So from the question
if 1 cm³ = 1 mL
Then 150 cm³ = 150 mL

Which of the following is not a possible effect of increasing carbon dioxide levels in the atmosphere?a.increase in water contamination and floodsb.ocean acidificationc.cutting down forestsd.reduction of cold-related deaths Please select the best answer from the choices providedABCD
Answer:
b
Explanation:
The only option that is not an effect of increasing carbon dioxide levels in the atmosphere is cutting down forests.
An increasing level of carbon dioxide in the atmosphere causes ocean acidification due to the dissolution of the gas in the oceans. Carbon dioxide also causes global warming - an increase in the average global temperature due to the heat (from the sun) absorbing ability of the gas.
Global warming causes an increase in the level of seas and oceans as a result of the melting of glaciers and polar ice caps. The rise in sea levels causes flooding with associated loss of habitats and biodiversity.
The increase in global temperature also means that cold-related deaths will reduce.
Correct option: b
Answer:
C. cutting down forests

PLEASE HELP !!! Read the passage below and use it to answer the question. Rainforests have four basic layers. The tallest trees are part of the emergent layer, which can be as much as 60 m above the ground. The sunlight is bright and hot here, and the wind can be strong. The main layer of the rainforest is the canopy, more than 20 m above the ground. It is made up of the leaves and branches of tree tops. The air here is still and very moist. The canopy blocks out most of the sunlight. Smaller trees, vines, and other plants make up the understory, which is less than 12 m above the ground. This layer is damp and warm with very little sunlight. The forest floor is dark, warm, and moist. Decomposers break up fallen leaves and other dead matter here.

15. An electrically neutral atom consists of 15 neutrons, 13 electrons, and a number of protons. What is its mass number?
Answer:
28
Explanation:
it states that the atom is neutral, meaning the number of electrons and protons are the same. so if there are 13 electrons, there are 13 protons. And the mass number is neutrons plus protons. So 13+15 is 28

How many grams of carbon (C) would be present in carbon monoxide (CO) that contains 2.666 grams of oxygen (O)?
Answer:
Explanation:
Given :
Mass of oxygen containing carbon monoxide (CO) is 2.666 gram .
To Find :
How many grams of carbon (C) would be present in carbon monoxide (CO) that contains 2.666 grams of oxygen (O) .
Solution :
By law of constant composition , a given chemical compound always contains its component elements in fixed ratio (by mass) and does not depend on its source and method of preparation.
So , volume of solution does not matter .
Moles of oxygen ,
Now , molecule of CO contains 1 mole of C .
So , moles of C is also 0.167 mole .
Mass of carbon ,
Therefore , mass of carbon is 2 grams .
Hence , this is the required solution .

Does more data mean more reliable results or less
Answer:
more reliable. The more results the better results you get.
Explanation:
Answer:
more reliable results
Explanation:
hey there,
< More data is more reliable results as you can see even more about the experiment you are doing! If you only know one other scientist that had done the experiment and it worked for him, then that's not enough data, but if you have thousands of scientists that were able to do the experiment correctly, you will have a more reliable and correct result since now you have more data. >
