Answer and explanation;
Coal has aromatic hydrocarbons with high molar mass and has a high ratio of carbon to hydrogen. Burning coal produces more soot than burning other fossil fuels does because of it.
Fossil fuel mixtures of hydrocarbons that formed from the remains of plants or animals. Burning fossil fuels increases the amount of carbon dioxide in the atmosphere. This increase may affect temperatures, amounts of rain and sea levels worldwide. Some sulfur and nitrogen are in fossil fuels, and air contains nitrogen.
The activation energy in the
diagram is 43.8 kcal/ mole, letter C. You have to note that activation energy
is the energy needed for the reaction to occur and produce products. Therefore,
the spike after H2 and I2 is reacted is the activation energy of the reaction.
The molarity of the Ca(OH)2 solution is calculated as follows
find the concentration of HCl used from the Ph
that is PH = - log H+= 1.3
H+ = 10^-1.3 = 0.05 M
the moles of HCl = molarity x volume/1000
= 0.05 x 300/1000=0.015 moles
write the reaction equation
that is Ca(OH)2 +2HCl=CaCl2 + 2H20
by use of reacting ratio between Ca(OH)2 to HCl (1:2) the moles of Ca(OH)2 is = 0.015 x1/2=7.5 x10^-3 moles
molarity is therefore = moles /volume in liters
= {( 7.5x10^-3) /50} x1000 = 0.15 M ( answer 5)
- 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.
