There are over a hundred elements known to date.

As an element, Gold is classified as a metal due to its very unique set of properties.

assuming nitrogen behaves like an ideal gas, what volume would 14.0 g of nitrogen gas (N2) occupy at STP? the gas constant is 0.
dimaraw [331]

Answer:

V = 22.41 L

Explanation:

Given data:

Mass of nitrogen = 14.0 g

Volume of gas at STP = ?

Gas constant = 0.0821 atm.L/mol.K

Solution:

Number of moles of gas:

Number of moles = mass/molar mass

Number of moles= 14 g/ 14 g/mol

Number of moles = 1 mol

Volume of gas:

PV = nRT

1 atm × V = 1 mol × 0.0821 atm.L/mol.K  × 273 K

V = 22.41 atm.L / 1 atm

V = 22.41 L

Which type of seismic waves produces the most severe ground movement?
Leto [7]
The surface waves are the type of seismic waves that produce the most severe ground movement. This wave is slow in nature and so produces a rolling effect similar to a surface wave in a pond. This kind of wave is far more devastating than the P waves and the S waves. The surface waves have the capacity to shake a building from side to side until it collapses. This kind of wave moves in a pattern similar to a circle. It actually originates at a point and then start moving outwards in a circle.

A 1500 kg race car accelerates at a rate of about 9M /s2 as to how much force does the engine need to create for this to happen
IgorC [24]

Answer:

13500 N

Explanation:

According to newtons second law of motion

mass m =1500 Kg

a = 9m/s^2

Force F = mass m × acceleration a

F = 1500×9= 13500 N
