According to their locations on the Periodic Table, argon (Ar) and neon (Ne) are

a_sh-v [17]

Your answer would be (D), Noble Gases, or Inert Gases - The far right on the periodic table is also known as Group(0)., or Group 18 on the periodic table. Elements in this group includes, Neon(NE), Argon(AR), Krypton(KR), Xenon(XE), and Radon(RN).

Hope that helps!!!

A wave of infrared light has a speed of 6 m/s and a wavelength of 12 m. What is the frequency of this wave?

andreev551 [17]

Answer: The frequency of the wave is 0.5 hertz.

Explanation:

$\nu =\frac{c}{\lambda }$

$\nu$ = Frequency of the wave

$c$ = speed of the light in m/s

$\lambda$ = Wavelength of the wave.

Here in question we are given with speed of the infrared light. So, we will replace the value of speed of light(c) from the given value of the speed of the infrared light.

Speed of infrared light = 6 m/s

$\nu =\frac{\text{speed of infrared light}}{\lambda }=\frac{6 m/s}{12 m}=0.5 hertz$

The frequency of the wave is 0.5 hertz.

What is the volume, in liters, of 2.00 moles of hydrogen at STP?

Ber [7]

The volume of one mole of any gas at STP is 22.4 L. So, at STP, the volume of 2.00 moles of hydrogen gas would be (22.4 L/mol)(2 mol H2) = 44.8 L.

E What caused the little puddle of water to appear under the syringe tip? its for sciences

fredd [130]

LMBO, for science.

Answer:

<em>The increase in kinetic energy leads to leakage of water from the syringe. When the outside temperature is more than the liquid temperature, say the syringe is out in sunshine, then the liquid becomes slightly warmer.</em>

A chemist measures the energy change ?H during the following reaction:

Leno4ka [110]

Answer:

(A) endothermic

(A) Yes, absorbed

Explanation:

Let's consider the following thermochemical equation.

2 Fe₂O₃(s) ⇒ 4 FeO(s) + O₂(g) ΔH = 560 kJ

Since ΔH > 0, the reaction is endothermic.

We can establish the following relations:

560 kJ are absorbed when 2 moles of Fe₂O₃ react.
The molar mass of Fe₂O₃ is 160 g/mol.

Suppose 66.6 g of Fe₂O₃ react. The heat absorbed is:

$66.6g.\frac{1mol}{160g} .\frac{560kJ}{2mol} =117kJ$
