Answer:
The new volume is 87.5 ml.
Explanation:
We have,
Volume of sample of neon is 175 ml
The pressure changed from 75 kPa to 150 kPa.
We need to find new volume.
It is based on the concept of Boyle's law. Let V₂ is new volume. So,
![P_1V_1=P_2V_2\\\\V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{175\times 75}{150}\\\\V_2=87.5\ ml](https://tex.z-dn.net/?f=P_1V_1%3DP_2V_2%5C%5C%5C%5CV_2%3D%5Cdfrac%7BP_1V_1%7D%7BP_2%7D%5C%5C%5C%5CV_2%3D%5Cdfrac%7B175%5Ctimes%2075%7D%7B150%7D%5C%5C%5C%5CV_2%3D87.5%5C%20ml)
So, new volume is 87.5 ml.
Protists are NOT prokaryotes so the answer would be B) False.
Al atom has 13 protons, 13 electrons.
Mass number = number protons + number neutrons
27 = 13 + number neutrons,
number neutrons =27 - 13 = 14 neutrons .
Ion Al³⁺, lost 3 electrons.
So, in Al³⁺, 13-3=10 electrons.
So, ion Al³⁺ has 13 protons,14 neutrons, 10 electrons.
The shortest distance taken by the object to reach the destination at a minimum time is called acceleration. Thus value acceleration depends upon the displacement and time.
The molecular formula C₅H₁₀O₅ and The scaling factor =5
<h3>Further explanation</h3>
Given
Molar mass = 150 g/mol
The empirical formula = CH₂O
Required
The scaling factor
Solution
The empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
<em>n = the scaling factor</em>
(CH₂O)ₙ=150 g/mol
(12+2+16)ₙ=150
(30)ₙ=150
n=5
The molecular formula : C₅H₁₀O₅
