Answer:
Explanation:
Hello!
In this case, since the reaction between hydrogen and oxygen to produce water is:
When equal masses of each reactant go in contact to carry out the reaction, we can identify the maximum mass of yielded water as the fewest mass yielded by each reactant, just as shown below:
Thus, since hydrogen yields more water than real, we limit the maximum mass of water to those 55.2 g yielded by oxygen as hydrogen would be in excess.
Best regards!
The effect is that it melts the ice and affects the climate by not have drinking water
Explanation:
During a physical change only the physical properties of a matter such as it state and form.
Physical properties of matter tells us everything about what a substance is and when no change is occurring to its constituents.
- In a physical change no new kind of matter is formed.
- it usually involves no change in mass
- requires little to no energy
- they are easily reversible
- examples are melting, boiling, freezing e.t.c

There are 7 electrons on the third energy level
<h3>Further explanation
</h3>
The maximum number of electrons that can be filled in the nth electron shell is 2n²(n=shell)
• K shell (n = 1) maximum 2 x 1² = 2 electrons
• L shell (n = 2) maximum 2 x 2² = 8 electrons
• M shell (n = 3) maximum 2 x 3² = 18 electrons
• N shell (n = 4) maximum 2 x 4² = 32 electrons
Electron configuration of Si : 1s²2s²2p⁶3s²3p⁵ = 17 electron
The electron distribution :
K shell(n=1) ⇒the first energy level= 2
L shell(n=2) ⇒the second energy level= 8
M shell(n=3)⇒the third energy level = 7
