The rounding up of the aforementioned number to four significant figures is as follows: 3.002 × 10²

<h3>What are significant figures?</h3>

Significant figures are figures that contribute to the general and overall value of the whole number.

Significant figures or digits are specifically meaningful with respect to the precision of a measurement.

Although, the original number given in this question has 9 significant figures, the number; 300.235800 can be rounded up to four significant figures as follows:

  • Decimal notation: 300.2
  • No. of significant figures: 4
  • No. of decimals: 1
  • Scientific notation: 3.002 × 10²

Therefore, the rounding up of the aforementioned number to four significant figures is as follows: 3.002 × 10².

0.446 g of hydrogen gas fills a 5.0 L bag determine the density of hydrogen
Oduvanchick [21]

The density of hydrogen : ρ = 0.0892 g/L

<h3>Further explanation</h3>

Given

mass of Hydrogen : 0.446 g

Volume = 5 L

Required

The density

Solution

Density is a quantity derived from the mass and volume  

Density is the ratio of mass per unit volume  

The unit of density can be expressed in g/cm³, kg/m³, or g/L

Density formula:  

\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}

Input the value :

ρ = m : V

ρ = 0.446 g : 5 L

ρ = 0.0892 g/L

Minchanka [31]

Answer:

A.   it is the lowest at low temperatures

Explanation:

It is true with respect to the kinetic energy of a molecule that the it is the lowest at low temperatures.

The kinetic energy of a molecule is the energy due to the motion of the particles within a substance.

  • Kinetic energy is directly proportional to the temperature of a substance.
  • The higher the temperature, the more the kinetic energy of the molecules within a system.
  • At low temperature, kinetic energy is the lowest.
  • At the highest temperature, kinetic energy is the highest

In the compound nh3, nitrogen has an oxidation number of 3+ and hydrogen has an oxidation number of ______________.
Digiron [165]
In the compound nh3, nitrogen has an oxidation number of 3+ and hydrogen has an oxidation number of -1
The molecule NH3 have a neutral charge so the number of oxidation number of it's component must be equal to zero. The molecule NH composed of 1 nitrogen and 3 hydrogens. If the nitrogen oxidation number is 3+, then hydrogen would be:

1* N + 3*H=0
1*+3  +3*H=0
3H= -3
H= -1
