Answer : The amount left of leutium-176 will be, 2.10 g
Solution :
First we have to calculate the rate constant, we use the formula :
Now we have to calculate the amount left of the sample.
Expression for rate law for first order kinetics is given by :
where,
k = rate constant =
t = decay time =
a = initial amount of the sample = 16.8 g
a - x = amount left after decay process = ?
Now put all the given values in above equation, we get
Therefore, the amount left of leutium-176 will be, 2.10 g
Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respirationconverts into ATP, the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the oxygen that we absolutely must have to stay alive. Oh yes, we need the food as well!
We can write the overall reaction of this process as:
6H2O + 6CO2 ----------> C6H12O6+ 6O2
Most of us don't speak chemicalese, so the above chemical equation translates as:
six molecules of water plus six molecules of carbon dioxide produce one molecule of sugar plus six molecules of oxygen
the answer to your question is
ρ≅13.0⋅g⋅mL−1 = 13.0⋅g⋅cm−3Explanation:Density=Mass Per unit Volume = 75.0⋅g(36.5−31.4)⋅mL =??g⋅mL−1Note that 1⋅mL = 1⋅cm−3; these are equivalent units of volume; i.e. 1⋅cm3 = 1×(10−2⋅m)3=1×10−6⋅m3=10−3⋅L=1⋅mL.
- Unsaturated fats include double bonds that provide structures that prevent development of tightly bonded compounds.
- The characteristics of the phospholipid head and tails determine how the phospholipids are arranged in the bilayer cell membrane.
This is why even though Olive oil and butter both contain fats, olive oil is liquid at room temperature and butter is solid.
- Since saturated fat makes up the majority of butter, it is solid at room temperature.
- Olive oil is an unsaturated fat since it is liquid at room temperature.
- Through hydrogenation processes, an unsaturated fat can be converted to a saturated fat.
<h3>What are saturated fats?</h3>
- a form of fat believed to be less healthy in the diet than unsaturated fat because it contains a higher percentage of fatty acid molecules lacking double bonds.
- butter, ghee, suet, lard, coconut oil and palm oil, cakes, biscuits, fatty cuts of meat are some of the examples.
<h3>What are unsaturated fats?</h3>
- a form of fat that is thought to be healthier in the diet than saturated fat because it contains a high percentage of fatty acid molecules with at least one double bond.
- Olive, peanut, and canola oils, Avocados, Nuts such as almonds, hazelnuts, and pecans, Seeds such as pumpkin and sesame seeds are some of the examples.
