sgsgueiehéyegeysuegeteue2

Answer:

Explanation:

The answers you put are correct...

crest- A crest point on a wave is the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum.

wavelength- In physics, the wavelength is the spatial period of a periodic wave the distance over which the wave's shape repeats. (how long the wave is)

trough- A trough is the opposite of a crest, so the minimum or lowest point in a cycle.

amplitude-  Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path. ... Waves are generated by vibrating sources, their amplitude being proportional to the amplitude of the source.

Silver nitrate and magnesium chloride react according to the following equation:
2AgNO3(aq) + MgCl2(aq) — 2AgCl(s) + Mg(NO3)2(aq)
What volume (in ml) of 0.247M MgCl2(aq) is required to react with 63.2 mL of 0.192M AgNO3(aq)?

Answers

Answer:

V=24,3mL

Explanation:

1)n(AgNO3)=Cm*V=0.063l*0.192M=0.012

2)n(AgNO3)/2=n(MgCl2) => MgCl2=0.012/2=0.006

3)V(MgCl2)=n/Cm=0.006/0.247=0.0243L=24,3ml

What is the element Ar classified as in the periodic table?
a noble gas
a halogen
a metalloid
a metal

Answers

it is classified as a noble gas

The element Ar classified as noble gas in the periodic table. Therefore, the correct option is option A.

What is noble gas?

The noble gases are a group of chemical elements that share several characteristics. They are all monatomic, odourless, and colourless gases with relatively little chemical reactivity under normal conditions. Oganesson (Og) is a highly radioactive element created synthetically.

Although the IUPAC has included oganesson since "group 18" and "noble gas" have been used interchangeably, oganesson may not be appreciably chemically noble and therefore is projected to deviate from the norm and just be reactive owing to relativistic effects. Its chemistry is still being studied due to the exceptionally short 0.7 ms ½ of its sole known isotope. The element Ar classified as noble gas in the periodic table.

Therefore, the correct option is option A.

Carbon-14 has a half-life of 5715 years. It is used to determine the age of
ancient objects. If a sample today contains 0.060 mg of carbon-14, how much
carbon-14 will be present after 28,575?

Answers

The sample of Carbon-14 after 28,575 years=0.001875 mg

Further explanation

General formulas used in decay:  

[tex]\large{\boxed{\bold{N_t=N_0(\dfrac{1}{2})^{T/t\frac{1}{2} }}}[/tex]

T = duration of decay  

t 1/2 = half-life  

N₀ = the number of initial radioactive atoms  

Nt = the number of radioactive atoms left after decaying during T time  

Carbon-14 has a half-life of 5715 years, so t1/2=5715 years

A sample today contains 0.060 mg of carbon-14, so No=0.06 mg, then :

[tex]\tt Nt=0.06(\dfrac{1}{2})^{28575/5715}\\\\Nt=0.06(\dfrac{1}{2})^5\\\\Nt=0.001875~mg[/tex]

How many moles of nitrogen gas would be produced if 3.27 moles of copper(II) oxide were reacted with excess ammonia in the following chemical reaction? 2 NH3(g) + 3 CuO (s) – 3 Cu(s) + N2(g) + 3 H2O(g)​

Answers

Moles of Nitrogen(N₂) gas would be produced : 1.09

Further explanation

The reaction coefficient in a chemical equation shows the mole ratio of the components of the reactants and products

If one mole of the reactant or product is known, then we can determine the moles of the other compounds involved in the reaction

Reaction

2NH₃(g) + 3CuO (s) ⇒ 3Cu(s) + N₂(g) + 3 H₂O(g)​

Copper(II) oxide was reacted with excess Ammonia, so CuO as a limiting reactant and moles of the product is based on moles of CuO

moles of CuO = 3.27

From the equation, the mol ratio of CuO : mol N₂ = 3 : 1, so mol  N₂ :

[tex]\tt \dfrac{1}{3}\times 3.27=1.09[/tex]
