Answer: 2 (2 neutrons are produced).
Explanation:
1) In the left side of the transmutation equationa appears:
²³⁵U + ¹n →
I am omitting the atomic number (subscript to the leff) because the question does not show them as it is focused on number of neutrons.
2) The right side of the transmutation equation has:
→ ¹⁴⁴Ce + ⁹⁰Sr + ?
3) The total mass number of the left side is 235 + 1 = 236
4) The total mass number of Ce and Sr on the right side is 144 + 90 = 234
5) Then, you are lacking 236 - 234 = 2 unit masses on the right side which are the 2 neutrons that are produced along with the Ce and Sr.
The complete final equation is:
²³⁵U + ¹n → ¹⁴⁴Ce + ⁹⁰Sr + 2 ¹n
Where you have the two neutrons produced.
Answer:
30.0 mol CO₂
Explanation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
To answer this problem we need to convert moles of C₃H₈ into moles of CO₂: We'll do that by using the <u>stoichiometric coefficients</u>, using a conversion factor that has C₃H₈ moles in the denominator and CO₂ moles in the numerator:
10.0 mol C₃H₈ * 
= 30.0 mol CO₂
Answer:
other than the periodic table, are often arranged by their properties
Explanation:
Money, they are arranged by how big or small they are, like coins, with pennies, dimes, and quarters.
Answer: here is a description of what they look like since I cannot see the diagram.
Mitochondria- wavy line
Ribosomes- little dots
Chromosome- X
Nucleus- Circle with bite taken out of it
Endoplasm- Bubble
Nuclear membrane- Outer layer/bubble
Golgi-wavy circle thing
Vacuole- Bigger circle (but not nucleus)
Cytoplasm- its the jelly on the inside
Cell wall- only in plant cells, looks like a box
Cell membrane- The outmost part of the animal cell, the barrier.
I sure hope this helps!!!
