"Theory relates to a model in science because it presents the possible paradigms and patterns of the said concept and fact. It explains and elaborates the phenomenon of why it happened, how it happened and the factors that are invovlved in the process. A theory is a possible explanation of certain occurence.
in addition, any time a scientific theory is challenged, it means it's not a good theory. And this statement is not valid. In theoretical models, they are revisited when there are further studies and discoveries found in a certain area where they can be remodeled and reintegrated instead of disregarding its credibility. Models, theories and paradigms are not challenged but rather encouraged, they are supported in many studies since these theories and models were created in order for us to understand a certain phenomenon but it would likely help the scientific society to be updated in the new forms or spheres of improvement rather than discouragement."
A. Acids and bases don't react with each other. --> False. Acids and bases react in reactions called neutralization reactions, whose products are salt and water.
B. Acids mixed with bases neutralize each other. --> True. See above.
C. Acids mixed with bases make stronger bases. --> False. Acids and bases react to neutralize each other, so they would weaken each other, not result in a stronger base or a stronger acid.
D. Acids mixed with bases make stronger acids. --> False. See above.
<h3>
Answer:</h3>
B. Acids mixed with bases neutralize each other
Here, we need to solve this problem using Ideal gas law ( PV=nRT).
Where –
- P = Pressure in atm
- V = Volume in L
- n = moles
- R = Ideal gas law constant
- T = Temperature in K
<u>Now, according to the question </u>–
- V = 58 L
- P = 2.2 atm
- T = 313 K
- R = 0.0821 atm L/ mol K
<u>Calculation</u> –

Change in size because that just means that more is added rather than anything reacting
Answer:
i dont have an answer for sure because it doesnt specify WHAT its energy chang occurs but i think its physical change
Explanation:
Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.
examples of chemical change:
burning a fire
boiling an egg
digestion
examples of physical change:
melting ice
rusting
breaking a pencil
hope i helped!!
