The reaction is not possible.
You are destroying O atoms and creating Cl atoms. An chemical reaction cannot convert atoms of one element to those of another element.
The first one is false the second one is the green house effect
Business owners must consider the products mission statement, a unique brand, the timing, the packaging, promotion, the audience.
To create a product you first need a problem then a solution. So if the problem is that water bottles aren’t holding enough water, the solution would be to create bigger yet lighter water bottles.
Let’s say you are to create a water bottle that is sturdier than others and can hold more water but weigh less. You would first consider the target audience. People that exercise and are into fitness would find the product more useful. So many making changes to the product to better fit their needs will help. Next the promotion and timing . It would be best to release the product near New Years since that’s when most people go to gyms. This will allow your product to reach a greater target audience and have more sales. Also testing your bottle to make sure it’s up to what you’re proving and so on.
Answer 1: The electron is a subatomic particle that has a negative charge. Electron cannot be sub-divided further. An electron has a mass that ia ~ 1/1836 that of the proton.
The positron is also refereed as an antielectron. The positron has the charge of +1e, a spin of 1⁄2. The similarity between positron and electron is that they have same mass.
Answer 2: <span>Positron decay occurs in nuclei having heavy mass. Positron emission decreases proton number relative to the neutron number. Positron also exhibits nuclear transmutation thereby producing an atom of a different element, as compared to parent element,. Them atomic number of daughter element is less as compared to parent element by 1.
Example: </span><span><span>23 12</span>Mg </span><span>→ </span><span><span>23 11</span>Na </span><span> + </span><span>e+ </span><span>+ energy
</span><span>
Answer 3: </span><span>Electron capture is also referred as </span>K-electron capture. It <span>involves absorption of energy, thereby resulting in loss of electron usually from K or L shell. In this process,following thing occurs simultaneously
i) a nuclear proton present in nuclei changes to a neutron, after reacting with an electron which falls into the nucleus from one of its orbitals (preferentially from K or L)
2) Emission of an electron neutrino.
Following is an example of K-electron capture.
7 4Be + 0 -1e </span>→ 7 3Li + energy
Answer 4: Following are the distinct features of <span>transmutations caused by positron emissions and electron capture.
i) Positron: </span><span>A proton get converted into neutron due to radio-active process. This process results in the emission of positron and neutrino. The<span> process results in decrease in atomic number by one unit, and however atomic mass number remains unchanged.
ii) Electron capture: </span></span><span>A electron from the low energy level (K-shell or L-shell) falls into the nucleus. Due to this proton is converted into neutron. During this process, neutrino is emitted from the nucleus. As seen in positron emission, t<span>he atomic number goes down by one unit, but atomic mass number remains unchanged.</span></span>
B is correct
salt lowers the freezing point of water (colligative property) by lowering the interaction and intermolecular forces between water molecules
