Answer:
<h3>The answer is 200 cm³</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question
mass = 150 g
density = 0.75 g/cm³
We have

We have the final answer as
<h3>200 cm³</h3>
Hope this helps you
Answer:
Critical coordinate drivers incorporate living space alter, climate alter, obtrusive species, over exploitation, and contamination. Most of the coordinate drivers of corruption in biological systems and biodiversity right now stay steady or are developing in escalated in most biological systems.
Explanation:
According to octet rule element has eight electrons in its valence shell.This give it the same electronic configuration as a group 18 elements.Atom with electronic configuration 1s2 2s2 2p1 require five electrons to achieve octet. This is because the valence electrons are 3 in 2s2 and 2p1 and hence require 5 electrons to be filled.
The molar mass of CO2 is 44 grams per mole.
165 grams / 44 grams per mole of CO2 = 3.75 moles CO2
Using Avogadro’s law where 1 mole of substance equals
6.023 x 10^23 molecules
3.75 moles CO2 (6.023 x 10^23 molecules /mole) = 2.26 x 10^24 molecules CO2
Answer:
HBr + H2O = H3O+ + Br-
So our conjugate acid is the H3O+ to H2O
Explanation:
A conjugate acid of a base results when the base accepts a proton.
Consider ammonia reacting with water to form an equilibrium with ammonium ions and hydroxide ions:
NH3 (aq) + H2O (l) ⇌ NH4+ (aq) + OH- (aq)
Ammonium, NH4+, acts as a conjugate acid to ammonia, NH3.
