A taxi hurries with a costant speed of 84km/h. How far it travel in 5 hour

1 answer:

8 0

Hey there! If the taxi travels 84km in one hour (without making any changes in speed aka remaining constant), then multiply 84(5) to find how many kilometers it would drive in one hour. 84(5)=420km

If the density of an ideal gas at stp if found to be 0.0902 g/l, what is its molar mass?

lisabon 2012 [21]

P=0.0902 g/l
v=22.4 l/mol (stp)

M=vp

M=22.4 l/mol * 0.0902 g/l=2.020 g/mol

M=2.020 g/mol

g Select the correct statements. I. Reduction is the loss of electrons, and oxidation is the gain of electrons II. Reduction is

Karolina [17]

Answer: The correct answer is Option D.

Explanation:

Reduction reaction is defined as the reaction in which a substance gains electrons. Here, the oxidation state of the substance decreases.

$X^{n+}+ne^-\rightarrow X$

Oxidizing agents are the agents that helps in the oxidation of other substance and itself gets reduced. These agents undergoes reduction reactions.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. Here, oxidation state of the substance increases.

$X\rightarrow X^{n+}+ne^-$

Reducing agents are the agents that helps in the reduction of the other substance and itself gets oxidized. These agents undergoes reduction reactions.

Oxidation state is the number which is given to an atom when it looses or gains electron. It is written as a superscript. In a compound, the total charge is equal to the sum of the charges of all atoms in that compound. For Example: In $MnO_4^-$ , manganese has +7 oxidation number and oxygen has -2.

So, the charge on the compound = $[=7+(4\times (-2))]=-1$

Hence, the correct answer is Option D.

the peak intensity of radiation for a particular star occurs at a wavelength of 2.0 nanometers and what spectral band is this

Dmitry_Shevchenko [17]

For a given peak intensity of radiation of a star that occurs at a wavelength of 2 nanometers, this is located at the spectral band of an X-ray. An X-ray's wavelength typically goes from 0.1 nano meters to 10 nano meters. Given that, the wavelength of the star fits perfectly into the range of an X-ray

Can someone help me out please ? I am very stuck here

Alex17521 [72]

Hey there!

Atomic Masses :

H = 1.00794 a.m.u
N = 14.0067 a.m.u
O = 15.9994 a.m.u

Therefore:

HNO3 = 1.00794 + 14.0067 + ( 15.9994 * 3 ) => 63.0128 g/mol
