eduard3 years ago
6 0

Answer:

Explanation:

we know that 1 km =1000 m and 1 hour =60 min

therefore

239 km/hr =239*1000m/60 min=3983.3 m/min

Answer:

3983.3333334 m/min

Explanation:

1 km/h is equal to 16.6667 m/min so 239 km/h is equal to 3983 .3334 m/min.

239(16.6667)= 3983.3334

What two things lead to genetic variation
vredina [299]

Answer:

Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Another source is gene flow, or the movement of genes between different groups of organisms. Finally, genetic variation can be a result of sexual reproduction, which leads to the creation of new combinations of genes.

Why isn't hess's law helpful for calculating the heat of reaction involved in the conversion of diamond to graphite?
faust18 [17]
Hess' Law of Constant Heat Summation was developed by Germain Henri Hess who lived from 1802 - 1850. This law became important primarily for his thermochemical studies. This law states that the heat released or absorbed in the chemical reaction is unchanged or the same irregardless of how many steps the reactants take in order to convert to products.

This law is not applicable or not helpful in the conversion of diamond to graphite because both are just allotropes of carbon along with C60 (Buckminsterfullerene or buckyball), C540, C70, amorphous carbon, and carbon nanotube.

Gaseous phosphorus pentachloride decomposes to gaseous phosphorus trichloride and chlorine at a temperature where K= 1.0x10^-3 m
love history [14]

Answer:

[PCl₃] = 0.031M

[Cl₂] = 0.031M

[PCl₅] = 0.969M

Explanation:

Based on the reaction:

PCl₅(g) ⇄ PCl₃(g) + Cl₂(g)

Keq is defined as:

<em>Keq = 1.0x10⁻³ = [PCl₃] [Cl₂] / [PCl₅]</em>

<em>Where [] are equilibrium concentrations of each species</em>

Inital [PCl₅] = 2.0mol / 2.0L = 1M.

In equilibrium:

[PCl₃] = X

[Cl₂] = X

[PCl₅] = 1M-X

Where X is reaction coordinate

Solving for X in Keq:

1.0x10⁻³ = [X] [X] / [1-X]

1.0x10⁻³ - 1.0x10⁻³X = X²

1.0x10⁻³ - 1.0x10⁻³X - X² = 0

X:

X = -0.032M. False solution, there is no negative concentration

X = 0.031M

That means equlibrium concentrations are:

[PCl₃] = 0.031M

[Cl₂] = 0.031M

[PCl₅] = 1-0.031M = 0.969M

<h3>[PCl₃] = 0.031M</h3><h3>[Cl₂] = 0.031M</h3><h3>[PCl₅] = 0.969M</h3>

Can someone plz help me with this one problem plzzzzz!!!
kobusy [5.1K]

Answer:

im gonna say A

Explanation:

i say A because i mean biotic potential is residing in the catagory birth rate which is how many the lay a year penguins have already reached the amount they are gonna lay robins the literally have no exact stop point its between 5 and 10 a year like said. so if u look at the amount they have each they have both reached there maximum point. but penguins only lay eggs once a year while robins well 5 to 10 reaching there maximum potential.
