In which type of chemical reaction do two or more substances combine to form one substance? A) synthesis
B) decomposition
C) single replacement
D) double replacement
Answers
The reaction in which two or more substances combine to form one substance is called a synthesis reaction, Option A is the correct answer.
What do you understand by a synthesis reaction ?
The reaction in which two or more molecules combine to form one or more different molecule is called a synthesis reaction.
These are also called as Combination Reaction.
Example Synthesis reaction of Ammonia from Hydrogen and Nitrogen , known as Haber's Process.
3H₂ + N₂-----> 2NH₃
This reaction takes place at high temperature and pressure.
Therefore , The reaction in which two or more substances combine to form one substance is called a synthesis reaction, Option A is the correct answer.

This hypothetical process would produce actinium-230.
Explanation
An alpha decay reduces the atomic number of a nucleus by two and its mass number by four.
There are two types of beta decay: beta minus β⁻ and beta plus β⁺.
The mass number of a nucleus stays the same in either process. In β⁻ decay, the atomic number increases by one. An electron e⁻ is produced. In β⁺ decay, the atomic number decreases by one. A positron e⁺ is produced. Positrons are antiparticles of electrons.
β⁻ are more common than β⁺ in decays involving uranium. Assuming that the "beta decay" here refers to β⁻ decay.
Gamma decays do not influence the atomic or mass number of a nucleus.
Uranium has an atomic number of 92. 238 is the mass number of this particular isotope. The hypothetical product would have an atomic number of 92 - 2 ⨯ 2 + 1 = 89. Actinium has atomic number 89. As a result, the product is an isotope of actinium. The mass number of this hypothetical isotope would be 238 - 2 ⨯ 4 = 230. Therefore, actinium-230 is produced.
The overall nuclear reaction would involve five different particles. On the reactant side, there is
- one uranium-238 atom.
On the product side, there are
- one actinium-230 atom,
- two alpha particles (a.k.a. helium-4 nuclei),
- one electron, and
- one gamma particle (a.k.a. photon).
Consider: what would be the products if the nucleus undergoes a β⁺ decay instead?

Another name for cytosol is cytoplasmic matrix. This fluid can be found inside cells. It has to do with how the cell's organelles are held in suspension.
Numerous crucial metabolic processes occur in the cytosol, which also serves as a conduit for the movement of chemicals and ions throughout the cell. It offers a dynamic setting that supports the cellular machinery and enhances the cell's overall functionality. The term "cytoplasmic matrix" refers to the fluid-like substance (cytosol) that provides the cytoplasmic organelles and molecules with their structural support.

I think, that the "hole"moves as it captures a free electron leaving another hole in a slightly different place. The electron leaving leaves a net + charge, which is attracted to the negative terminal. Because the "hole" behaves as a positive charge it is attracted towards the negative terminal.
Answer:
A. attracted to the negative terminal of the voltage source.
Explanation:
bc that is what the hole that's left behind does

So, substituting isoleucine at position 54 with leucine or valine would be expected to cause the least disruption in the protein’s three-dimensional structure because they share similar properties. These substitutions involve changing one aliphatic, nonpolar amino acid with another, which is less likely to significantly affect the protein’s overall structure and function.
