Answer:
The correct answer is A an ionic bond is a bond between charged atoms,while a covalent bond is a bond between neutral atoms.
Explanation:
Ionic bond is formed between two atom that have huge difference in their electronegativity.The one atom loses electron thus becomes positively charged another atom receives that electron thus becomes negatively charged.
For example NaCl
Covalent bond is formed by the sharing and paring of electrons.
For example H2O
Carbon and iron alloys are called steel.
Answer:
1. 2Na + 2HCl = 2NaCl =H2
2. 2Mg + O2 = 2MgO
Explanation:
make sure that the number of atoms of each element is the same on each side of the equation
1. 2Na + 2HCl = 2NaCl =H2
<em><u>on LHS of equation,</u></em>
Na = 2
H = 2
Cl =2
<em><u>On RHS of equation, </u></em>
Na=2
H= 2
Cl =2
2. 2Mg + O2 = 2MgO
<em><u>on LHS of equation,</u></em>
Mg = 2
O2 = 2
<em><u>On RHS of equation, </u></em>
Mg = 2
O2 = 2
<em><u /></em>
<u>Answer:</u>
The disposal method used for high-level nuclear waste Concentrate and contain
<u>Explanation:</u>
High intensity nuclear waste is an underlying issue for the world where the generated nuclear waste is one side very hazardous and on other side would help us in many viable processes but the negative sides of a consequence just outnumber the positive sides of the situation.
Concentrate and contain is a waste disposable method which enables the nuclear waste to be preserved and isolated and later be used when the time comes. Other methods would not be suggested because they could cause a huge amount of dangerous radioactivity in oceans which is often harmful for people.
