Answer:
negative charge
Explanation:
Neutrons have no charge, protons have positive charge, and electrons have a negative charge
Hi , here's the definition:
Cycloalkanes are cyclic hydrocarbons , meaning that the carbons of the molecule are arranged in the form of a ring.

Answer:
2, 2, 1
Explanation:
The coefficient of H₂O will be 2 because we have 2 oxygens on the right side but only one on the left side. Now, we have 4 hydrogens on the left side but only 2 on the right side. To balance, we'll add a 2 as the coefficient of H₂. We don't need to change the coefficient of O₂ because the equation is already balanced.
Final answer, 2, 2, 1.
The true about element in period or horizontal row of periodic table is
Each element has one more outer electron than the element before it. (answer B)
<u><em> Explanation</em></u>
In periodic table there are four horizontal rows(periods) that is period 1,2,3 and 4.
Across the period each element has one more electron than element before it.
For example Na and Mg which are in periodic 3.
Na has 2.8.1 or [Ne] 3s¹ electron configuration while Mg has 2.8.2 or [Ne] 3S² electron configuration.
Since Mg has 2 outer electrons while Na has 1 outer electron, Mg has more electron than Na.
The volume occupied by 0.118mol of He gas at a pressure of 1.05 atm and temperature of 322k is calculated by use of ideal gas equation
that is PV = nRT
P(Pressure)1.05 atm
v(volume)=?
n (number of moles)=0.118 mol
T(temperature)= 322K
from equation above volume(v)= nRT/p
volume(v) = (0.118 mol x 0.0821 L.atm/k.mol x322k) / 1.05 atm = 2.97 L
