If they're half life, wouldn't that mean every 5730 years I would double? So 12.5 x 2= 25, 25 x 2 = 50, and 50 x 2 = 100% carbon-14. It doubled 3x so the 5730 x 3 = amount of years the volcano erupted
Answer:
<u>In this reaction heat is released</u>
Explanation:
Exothemic Reactions : Those reactions in which heat is released when the products are formed .
For such reaction The enthalpy change is negative.
for exothermic reaction
Endothermic Reactions : Those reaction which proceed by absorbing heat . Here heat is absorbed. The enthalpy change for such reactions is positive.
When the direction of reaction reverses , the value of H also changes.
In the given reaction,
= heat is absorbed
So,
= heat is<u> released</u>
<u></u>
<u>E</u><em>xothermic reactions are more spontaneous as compared to endothermic ractions. This means that they proceed own their own . Only little amount of energy is supplied to exothermic reaction to produce the prodct.</em>
Answer:
0.21 g
Explanation:
The equation of the reaction is;
NaCl(aq) + AgNO3(aq) -----> NaNO3(aq) + AgCl(s)
Number of moles of NaCl= 0.0860 g /58.5 g/mol = 0.00147 moles
Number of moles of AgNO3 = 30/1000 L × 0.050 M = 0.0015 moles
Since the reaction is 1:1, NaCl is the limiting reactant.
1 mole of NaCl yields 1 mole of AgCl
0.00147 moles of NaCl yields 0.00147 moles of AgCl
Mass of precipitate formed = 0.00147 moles of AgCl × 143.32 g/mol
= 0.21 g
Answer:
A)Hydrogen can be stored physically as either a gas or a liquid. Storage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure). Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is −252.8°C.
B) carrying capacity of the lithium reserve will reach 10 million EV and 90 billion CE's RLBs for 50% recycling of lithium-containing waste, and 15 million EV and 150 billion CE's RLBs for 90% recycling.

Hope this helped Mark BRAINLEST!!
Answer:
That means an atom with a neutral charge is one where the number of electrons is equal to the atomic number. Ions are atoms with extra electrons or missing electrons. When you are missing an electron or two, you have a positive charge. When you have an extra electron or two, you have a negative charge.
