Dry ice last longer then normal ice and it stays in its form longer buy in bulk from certain places may be cheaper. When ice is being shipped for a longer amount of time it will keep the ice cream colder because it last much longer and gets to -78.5 c or -109.3 f
Answer:
C the mass of the reactant molecules is the same as the mass of the product
Number of atoms in 1.4 mol of Phosphorus trifluoride (PF₃) : 8.428 x 10²³
<h3>Further explanation </h3>
The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
1.4 mol of Phosphorus trifluoride (PF₃), number of atoms :

Convergent plates slowly come together, and over an amount of time, push together, and one either submerges, or they both buckle. Either way can form a mountain, because either way raises land up to the point where it eventually forms mountains.
Answer:
1.0 moles of N2
Explanation:
since
1.0 × avogadro's no# = same answer for SO2 and N2
avogadro's no#= 6.02× 10²³
