Ligase is The Gluer Not sure The Builder

COMPARE: Identify three ways that a biologist’s research is similar to an astronomer’s.

dalvyx [7]

Biologist and astronomer both use tools that magnify so they are able to view minute objects. Astronomers use telescopes while biologists use microscopes.
They both require data science due to the enormous data they are collecting that needs to be analyzed. Astronomers are collecting data on millions of stars and galaxies. Biologists require data science to analyze the enormous genomic data from populations.
Both fields involve making new discoveries due to the enormity of the scale in their scopes. Biologists and astronomy attempt to find new planets and those that could harbor extra-terrestrial life while biology attempts to find new undiscovered species of organisms on earth.

A) Find the gas speed of ammonia at 25.0 degrees Celsius. ______________

Cloud [144]

a. 661.23 m/s

b. the rate of effusion of Ammonia = 4.5 faster than Silicon tetra bromide

<h3> Further explanation </h3>

Given

T = 25 + 273 = 298 K

Required

a. the gas speed

b. The rate of effusion comparison

Solution

a.

Average velocities of gases can be expressed as root-mean-square averages. (V rms)

$\large {\boxed {\bold {v_ {rms} = \sqrt {\dfrac {3RT} {Mm}}}}$

R = gas constant, T = temperature, Mm = molar mass of the gas particles

From the question

R = 8,314 J / mol K

T = temperature

Mm = molar mass, kg / mol

Molar mass of Ammonia = 17 g/mol = 0.017 kg/mol

$\tt v=\sqrt{\dfrac{3\times 8.314\times 298}{0.017} }=661.23~m/s$

b. the effusion rates of two gases = the square root of the inverse of their molar masses:

$\rm \dfrac{r_1}{r_2}=\sqrt{\dfrac{M_2}{M_1} }$

M₁ = molar mass Ammonia NH₃= 17

M₂ = molar mass Silicon tetra bromide SiBr₄= 348

$\rm \dfrac{r_1}{r_2}=\sqrt{\dfrac{348}{17} }=4.5$

the rate of effusion of Ammonia = 4.5 faster than Silicon tetra bromide

PLEAS HELP I HAVE LIMITED TIME!!

Burka [1]

Answer:

H2 is the limiting reactant.

Explanation:

From the diagram above:

H2 => White ball

O2 => Red ball

Before the reaction

H2 => White ball => 10

O2 => Red ball => 7

After the reaction

H2O => White and red ball => 10

O2 => 2

From the simple illustration above, we can see that all the H2 were used up in the reaction but there are left over of O2.

This simply means that H2 is the limiting reactant as all of it is used up in the reaction while O2 is the excess reactant as there are leftover.

What is the difference between a molecular formula and a molecular modle?

ankoles [38]

The molecular formula tell us what elements the atoms are, and how many moles and atoms are attributed toward each element.
The molecular model tells us how the atoms/elements are bonded together.

Molecular formula : CH4

H
l
Molecular model: H -- C -- H
l
 H

Hey what's the value of pi till 5 digits after decimal

puteri [66]

Answer:

Pi to 5 decimals is 3.14159-

Brainlist pls!

P.S. It's a repeating number, but you can just put a (-), so that you don't have to type the whole thing out.
