What information do the chemical hazard label and msds have in common

if shoto todoroki has a half hot half cold quirk and he eats a ice cube does one half melt and one half freeze

Elis [28]

Answer:

in a way yes and no

Explanation:

shoto can control the temperature of both of his quirks so one can over power the other

he can melt the ice with the fire

and freeze the fire over the ice

hope it helps

Monodisperse polyacrylonitrile contains molecules with the general formula -(CH2CHCN)n-, where n is typically greater than 10,00

pentagon [3]

Answer:

7.68 × 10²⁴

Explanation:

Step 1: Calculate the mass of 1 molecule of the monomer CH₂CHCN

We will get the mass of the monomer by adding the masses of the elements.

mCH₂CHCN = 3 × mC + 3 × mH + 1 × mN

mCH₂CHCN = 3 × 12.01 amu + 3 × 1.01 amu + 1 × 14.01 amu = 53.07 amu

Step 2: Convert the mass of the monomer to grams

We will use the conversion factor 1 amu = 1.66 × 10⁻²⁴ g

53.07 amu × 1.66 × 10⁻²⁴ g/1 amu = 8.81 × 10⁻²³ g

Step 3: Calculate "n"

We will divide the mass of the polymer by the mass of the monomer.

n = 676.8 g / 8.81 × 10⁻²³ g = 7.68 × 10²⁴

0 ml from a 2.0 m solution of hcl is diluted to 10.0 ml using deionized water. what is the concentration of the new solution?

krok68 [10]

The concentration would remain at 2.0m. The problem states that 0 ml from the 2.0 m solution is diluted, therefore implying that none of it was diluted. Therefore, the level of concentration of the new solution would be the same as before.

How many atoms and ions does lithium sulfite have?

Serhud [2]

Answer:

Hence the ions per mole are:

$Li^{+}= 2 ions$

$SO_{3}^{2-}(aq)= 1 ions$

In one mole of Li2SO3 , the number of the atoms are

$N_{a}=6.022\times 10^{23}$

Explanation:

The formula of lithium sulfite is Li2SO3.

$Li_{2}SO_{3}$

It contain Li+ and SO3(2-) ions.This can be represented by :

$Li_{2}SO_{3}(s)\rightarrow 2Li^{+}(aq) +SO_{3}^{2-}(aq)$

Hence one mole of Li2SO3 will give 2 Li+ ions and 1 SO3 (2-) ion.

Hence the ions per mole are:

$Li^{+}= 2 ions$

$SO_{3}^{2-}(aq)= 1 ions$

Number of atoms in lithium sulfite depends upon the mass of the Li2SO3 present .

Li2SO3 = 93.94 g/mole

This mass is equal to 1 mole of Li2SO3

Now 1 mole of any substance contain Na atoms . This is known as Avogadro Number.

$N_{a}=6.022\times 10^{23}$

Hence , if 1 mole of Li2SO3 is present then it contains Na atoms

If other then 1 mole present then number of atoms are calculated by:

$Number\ of\ Atoms=Moles\times (N_{a})$

Here n = number of moles

if the mass of the compound is given then first calculate the number of moles.

$Moles=\frac{mass}{Molar\ mass}$

What is the name of the product isotope formed when Radon-222 decays by alpha decay?

katrin2010 [14]

Answer: Radon-222 is generated in the uranium series from the alpha decay of radium-226, which has a half-life of 1600 years. Radon-222 itself alpha decays to polonium-218 with a half-life of approximately 3.82 days, making it the most stable isotope of radon. Its final decay product is stable lead-20
