Differentiate between acids and bases on the basis of their pH values.
Answers
Answer:
acid; there ph value is mostly 7
base: there ph value can be more than 7 or less than 7
Answer:
The more towards 0 a pH value is, the increasingly acidic. Conversely, the more towards 14 a pH value is, the increasingly alkaline. Some examples of bases are lye, ammonia, and seawater. Some examples of acids are vinegar, lemon juice, and battery acid. To determine the pH of a liquid, you can use pH strips. Depending on the color (the redder the more acidic, the bluer the more alkaline), you can determine the pH of whatever you are trying to measure.

higher temperature, more kinetic energy, more space between particles, higher volume
higher temperature, less kinetic energy, less space between particles, higher volume
higher temperature, more kinetic energy, less space between particles, lower volume
higher temperature, less kinetic energy, more space between particles, lower volume
Answers
Answer:
higher temperature, more kinetic energy, more space between particles, higher volume
This is true because increase in temperature kinetic energy increase so molecules move apart and increase volume

Help needed: Which of the following is the correct name for N2S5?
A. Dinitrogen sulfide
B. Dinitride pentasulfur
C. Dinitrogen pentasulfide
D. Nitrogen sulfide
Answers
Answer:
dinitrogen pentasulfide
Explanation:
The correct name for the compound N₂S₅ is Dinitrogen pentasulfide and the correct option is option C.
Naming of compounds refers to the systematic process of assigning names to chemical compounds based on their composition and structure. It involves following certain rules and conventions to generate appropriate names that accurately represent the chemical formula and characteristics of the compound.
In inorganic chemistry, naming compounds often involves identifying the elements present and specifying their respective oxidation states or charges. Various naming conventions, such as the Stock system and the common system, are used depending on the type of compound and the specific elements involved.
Thus, the ideal selection is option C.

If a 50kg car is pulling a 30kg car, how much force would be required to accelerate the cars at 2m/s/s?
Answers
Answer:
160N
Explanation:
The force required to accelerate the two cars can be calculated thus:
F = m × a
Where;
F = force (Newton)
m = mass (kg)
a = acceleration (m/s²)
However, according to the question, a 50kg car is pulling a 30kg car, which means that the mass of the two cars is 50kg + 30kg = 80kg.
a = 2m/s²
F = ma
F = 80 × 2
F = 160N

If 50. mL of 1.0 M NaOH is diluted with distilled water to a volume of 2.0 L, the concentration of the resulting solution is A0.025 M B 0.050 M C 0.10 M D 0.50 M E 1.0 M M
Answers
Answer: The concentration of the resulting solution is 0.025 M
Explanation:
According to the dilution law,
[tex]M_1V_1=M_2V_2[/tex]
where,
[tex]M_1[/tex] = molarity of concentrated [tex]NaOH[/tex] solution = 1.0 M
[tex]V_1[/tex] = volume of concentrated [tex]NaOH[/tex] solution = 50 ml
[tex]M_2[/tex] = molarity of diluted [tex]NaOH[/tex] solution = ?
[tex]V_2[/tex] = volume of diluted [tex]NaOH[/tex] solution = 2.0 L = 2000 ml (1L=1000ml)
Putting in the values we get:
[tex]1.0\times 50=M_2\times 2000[/tex]
[tex]M_2=0.025M[/tex]
Therefore, concentration of the resulting solution is 0.025 M
The concentration of the resulting solution if 50. mL of 1.0 M NaOH is diluted with distilled water to a volume of 2.0 L is 0.025M
HOW TO CALCULATE FINAL CONCENTRATION:
The concentration of a solution can be calculated by using the following formula:C1V1 = C2V2
Where;
C1 = initial concentration (M)C2 = final concentration (M)V1 = initial volume (L)V2 = final volume (L)According to this question;
C1 = 1.0MV1 = 50mLC2 = ?V2 = 2000mL = 2L1 × 50 = C2 × 200050 = 2000C2C2 = 50 ÷ 2000C2 = 0.025MTherefore, the concentration of the resulting solution if 50. mL of 1.0 M NaOH is diluted with distilled water to a volume of 2.0 L is 0.025M.Learn more at: https://brainly.com/question/17329736?referrer=searchResults

An object is located 360 millimeters from a converging lens. The image formed is 150 millimeters high, at a distance of 90 millimeters from the lens. What’s the height of the object?
Answers
The height of the object : 600 mm
Further explanationGiven
d object=360 mm(object distance)
d image=90 mm(image distance)

Solution
focal length = f :
[tex]\tt \dfrac{1}{f}=\dfrac{1}{d_o}+\dfrac{1}{d_i}\\\\\dfrac{1}{f}=\dfrac{1}{360}+\dfrac{1}{90}\rightarrow f=72~mm[/tex]
The magnification :
[tex]\tt M=\dfrac{d_i}{d_o}=\dfrac{90}{360}=0.25[/tex]
