Answer:
ZnO + 2HCl → ZnCl₂ + H₂O
Explanation:
The <em>unbalanced reaction</em> between zinc oxide (ZnO) and dilute hydrochloric acid (HCl) is:
Now we'll procede to <u>balance the equation</u>:
- <em>There is 1 Cl atom on the left side and 2 on the right</em>, so we change that:
The number of atoms for each element is the same on both sides, so the equation is now balanced.
Answer:
The number of neutrons present in one atom of isotope of Silicon of mass 28 amu is<u> 14 neutrons</u>
Explanation:
Symbol of Si isotope
<u>Number of Neutron = Mass number - Atomic Number</u>
Mass number = Total number of protons and neutrons present in the nucleus of the atom.For Si = 28 amu
Atomic Number = Total number of Protons present in the nucleus.
Si = 14
Number of neutron = 24 - 14
= 14
D is the correct answer
every other option contains an element
Answer: All living things move in some way. This may be obvious, such as animals that are able to walk, or less obvious, such as plants that have parts that move to track the movement of the sun. All living things grow. Earthworms hatch from eggs and can grow up to a metre or more in length! Some earthworms are also able to regrow small parts of their body that have been lost or injured. Chromists are a diverse group of plant-like organisms and range from very small to very large. They are found in almost all environments.
