Answer:

1s22s22p3.

Explanation:

Electronic configuration of a neutral atom is 1s22s22p3.

Please see the image attached

Neutral atom of nitrogen will have equal number of proton and electron i.e equal to 7. 7 electron of the nitrogen are placed into the s and p orbitals in the ground state.

Water _____.

Sergio039 [100]

Answer: is neither an acid nor a base

Explanation: Water is a universal solvent which means it can dissolve most of the substances in it.

Water has high thermal heat capacity , which means large heat is required to heat the water.

Water is not always pure as it gets contaminated by various pollutants present in the atmosphere such as gases, bacteria and suspended matter.

Water is an amphoteric substance which can act as both acid and base, thus can donate and acept [texH^+[/tex] ions.Thus it is neither an acid nor a base.

$HCl+H_2O\rightarrow H_3O^++Cl^-$

Here water is accepting a proton, thus it acts as base.

$NH_3+H_2O\rightarrow NH_4^++OH^-$

Here water is donating a proton, thus it acts as acid.

a. Calculate the pH of a solution that has [H3O+]= 4.3 x 10-5 M. b. Is the solution acidic or basic? How do you know?

Luda [366]

Answer:

* $pH=4.37$

* The solution is acidic since the pH is below 7.

Explanation:

Hello,

In this case, we can mathematically define the pH by:

$pH=-log([H_3O^+])$

Thus, for the given hydronium concentration we simply compute the pH:

$pH=-log(4.3x10^{-5})=4.37$

Thereby, we conclude the solution is acidic due to the fact that the pH is below 7 which is the neutral point and above it the solutions are basic.

Regards.

select from this list the one metal or alloy that is best suited for each of the following applications, and cite at least one r

Brut [27]

List of metal or alloy that is best-suited include :

1) Block of an internal combustion engine is made of grey cast iron because it is ductile and hard enough to bear the loads.

2) Steam heat exchanger is made up of stainless steel material as it has high resistance to corrosion and has the capacity to bear high-temperature differences.

3) For jet engine turbofan blades, titanium alloys are being used because they can able to bear high pressure and high energy loads.

4) Tool steel is used to make drill bit material as it has high tensile and point strength.

5) Aluminum alloys are used for cryogenic applications as it is the best suited for work at low temperatures.

6) Magnesium is used for pyrotechnics as it gives works on the effect of heat, light, and gas.

Alloy, a metallic substance composed of two or more elements, as both a compound or a solution. The components of alloys are ordinarily themselves metals, though carbon, a nonmetal, is an essential constituent of metal.

Alloys, in trendy, are more potent and harder, less malleable, much less ductile, and greater corrosion-resistant than the alloy's predominant metallic.

An alloy is created with the aid of mixing metallic with another issue, both any other metal or a nonmetal substance. Metallic alloys are commonly made by means of melting the substances, mixing them collectively, after which letting them cool to room temperature, ensuing in a strong material.

A cube of an unknown metal is 1.25 inches on each side and has a mass of 128.3741 g. What is its' density?

Mademuasel [1]

Hey there!

To find the density of an object, you must use this formula:
Density=Mass/Volume

Knowing that your mass is 128.3741, the only information you need left would be to find the volume of the cube.

Because the side length of the cube is given, you can multiply the length three times in order to find its volume:
1.25*1.25*1.25
=1.953125

Now that you have your volume and mass, divide the mass by the volume to find the density:
128.3741/1.953125
=65.7275392

Therefore, your density would be 65.7275392 grams per inches cubed.
