Answer:
Disrupts communication systems
Composed of charged particles
travels at about 400 km/s
Answer:
Less than 7 so it is going to be acidic.
Explanation:
A buffer solution is one that resists changes in pH when small quantities of an acid or an alkali are added to it. An acidic buffer solution is simply one which has a pH of less than 7. Acidic buffer solutions are commonly made from a weak acid and one of its salts - often a sodium salt.
Answer : The value of 'R' is 
Solution : Given,
At STP conditions,
Pressure = 1 atm
Temperature = 273 K
Number of moles = 1 mole
Volume = 22.4 L
Formula used : 
where,
R = Gas constant
P = pressure of gas
T = temperature of gas
V = volume of gas
n = number of moles of gas
Now put all the given values in this formula, we get the values of 'R'.


Therefore, the value of 'R' is
.
<span>Number of moles ( of N20) = mass / molar mass = 88.0g / 44.01g/mole = 2 moles
So, there's 2 moles of N20, and in every molecule there's 2 nitrogen atoms -> there's 4 moles of nitrogen in 88.0g of N20</span>
Electronegativity of the two atoms is your answer
