<h2>Answer:</h2><h3>Vitalism-</h3>
- A theory that an organic molecule cannot be produced from inorganic molecules, but instead can only be produced from a living organism or some part of a living organism. The theory was disproved in the early part of the 19th century<em>.</em>
<em>Translated</em><em>~</em>
- Teoría de que una molécula orgánica no se puede producir a partir de moléculas inorgánicas, sino que solo se puede producir a partir de un organismo vivo o de alguna parte de un organismo vivo. La teoría fue refutada a principios del siglo XIX.
Answer:
Measuring the Volume of Solids
Rectangular prism - Multiply the measurement of the length times the width, then times the height.
Cube - Since all sides are the same measurement, it would be the measurement of any side, or edge, cubed, or a³
Explanation:
Answer:
the mass number is 40 g/mole
Answer:) is related to the change in free energy of the reaction--d
Explanation:
For any reaction that is taking place at any moment the change in Gibbs Free Energy is related to the reaction quotient as
ΔG=ΔG⁰+RTlnQ
where R-Universal Gas Constant, T- Temperature in Kelvin, Q is the reaction quotient
Now when the system is in equilibrum, ΔG⁰ which is the standard Gibb's Free Energy,is then defined as
ΔG⁰=−RTlnK ,
where K is the equilibrium constant. because ΔG becomes 0 and reaction quotient Q = K
The equilibrum constant is related to the change in free energy of the reaction.
because when ΔG is negative, the value of K is high which leads to a spontaneous. reaction
when ΔG is positive, the value of K is low, which leads to a spontaneous. reaction in the opposite direction.
Answer: alkaline earth metals (group-IIA)
Explanation:
The element which donates the electron is known as electropositive element and forms a positively charged ion called as cation. The element which accepts the electrons is known as electronegative element and forms a negatively charged ion called as anion.
Alkaline earth metals donate 2 valence electrons to acquire noble gas configuration.
For example: Berrylium is the first alkaline earth metal with atomic number of 4 and thus has 4 electrons
Electronic configuration of berrylium:
![[Be]:4:1s^22s^2](https://tex.z-dn.net/?f=%5BBe%5D%3A4%3A1s%5E22s%5E2)
Berrylium atom will loose two electrons to gain noble gas configuration and form berrylium cation with +2 charge.
![[Be^{2+}]:2:1s^2](https://tex.z-dn.net/?f=%5BBe%5E%7B2%2B%7D%5D%3A2%3A1s%5E2)
Thus Elements donate 2 electron to produce a cation with a 2+ charge are alkaline earth metals.
