Water is often referred as a <span>universal solvent </span>because it is capable dissolving much more solutes as compared to any other solvent. This is because, water is a high polar molecule. In water, H has partial positive charge while O has partial negative charge.
Due to this, water favors dissociation of molecules into positively and negatively charged ions. Positively charge ions gets attracted towards oxygen i.e. negatively charges, while negatively charged ions get attracted towards positive end of water molecule.
However, it is worth nothing that, despite water being referred as universal solvent, many compounds are insoluble or partially soluble in water. For instance, most of the hydroxide displays poor solubility in water.
Answer:
B
Explanation:
Si no demuestra que funciona te estarían estafando
B. The inhibitor wouldn’t stop sunlight or water, but it stops glucose production (from photosynthesis) and u could call glucose the plant’s food.
We have to know final temperature of the gas after it has done 2.40 X 10³ Joule of work.
The final temperature is: 75.11 °C.
The work done at constant pressure, W=nR(T₂-T₁)
n= number of moles of gases=6 (Given), R=Molar gas constant, T₂= Final temperature in Kelvin, T₁= Initial temperature in Kelvin =27°C or 300 K (Given).
W=2.4 × 10³ Joule (Given)
From the expression,
(T₂-T₁)=
(T₂-T₁)= 
(T₂-T₁)= 48.11
T₂=300+48.11=348.11 K= 75.11 °C
Final temperature is 75.11 °C.
<h2>The isotopes of an element all have the same __(atomic, mass) __number, but they have different __(atomic,mass)__numbers.</h2>
Explanation:
The isotopes of an element all have the same __atomic number __, but they have different __mass __numbers.
The isotopes have same atomic number that is :
- Same number of electrons
- Same number of protons
- same electronic configuration
- same valence electrons
- same valency
- same symbol
The isotopes have different mass number that is :
They differ in number of neutrons .
For example : Isotopes of hydrogen are : H₁¹ , H₁² , H₁³
isotopes of Oxygen is : O¹⁶ , O¹⁷, O¹⁸
