Answer:
Pascal's principle : Pressure applied to an enclosed fluid is transmitted undiminished to every part of the fluid, as well as to the walls of the container.
A common application of this is a hydraulic lift used to raise a car off the ground so it can be repaired at a garage. A small force applied to a small-area piston is transformed to a large force at a large-area piston. If a car sits on top of the large piston, it can be lifted by applying a relatively small force to the smaller piston, the ratio of the forces being equal to the ratio of the areas of the pistons.

Answer:
the maximum energy available for pumping a mole of glucose into the cell = 3190J
Explanation:
The detailed steps and appropriate derivation from the Vant hoff Isotherm equation is as shown in the attachment.
Answer:
AgNO₃(aq) + NaCl(aq) ⇄ AgCl(s)↓ + NaNO₃(aq) Kps
2K₃PO₄(aq) + 3MgCl₂(aq) ⇄ 6KCl (aq) + Mg₃(PO₄)₂ (s)↓ Kps
Explanation:
In the first reaction (1) we have:
Silver nitrate and sodium chloride as the reactants. Then the products will be, silver chloride (s) and sodium nitrate.
We know that all the salts from the nitrate are soluble, so the chloride will react to the silver cation to make the precipitate, an insoluble salt.
AgNO₃(aq) + NaCl(aq) ⇄ AgCl(s)↓ + NaNO₃(aq) Kps
For the second reaction (2), the reactants are:
Potassium phosphate and magnessium chloride
Phosphate salts are insoluble, except for the group 1. The same as chloride that makes soluble salts with the elements from the group 1.
The equation that makes the precipitate is.
2K₃PO₄(aq) + 3MgCl₂(aq) ⇄ 6KCl (aq) + Mg₃(PO₄)₂ (s)↓ Kps
Answer:
any salt
sodium chloride
callcium chloride
potassium chloride
Explanation:
There is no general effect of temperature on the solubility of salts.effect of increase temperature on the solubilty of NaCl is not significant because it is more soluble even at low temperature. The salt like potassium iodide (KI) has negative heat of solution so it's solubility decreases with increase of temperature…
Answer:
When fossil fuels are bumed they release toxic gases into the air that cause pollution and increase global warming
Explanation:
Fossil fuels are fuels which were formed from the remains of dead plants and animals buried underground for millions of years ago, which anaerobic bacteria and the high pressure and heat underground transformed into the fuels as we know them today. Fossil fuels are mainly hydrocarbons and they include coal, petroleum, natural gas, oil shales, bitumens, tar sands, and heavy oils.
The combustion of fossils fuels today provides the majority of the energy used by man worldwide. Energy from fossil fuels power our homes and industries, cars, trains aeroplanes, etc.
However, the combustion of fossil fuels impacts the environment negatively. Fossil fuels produce carbon dioxide as end-products when burnt which pollutes the airanspd is a major greenhouse gas contributing to global warming.
Combustion of fossil fuels releases acidic gases such as sulfur dioxide, nitrogen dioxide to the environment resulting in acid rains as well as many unpredictable and negative changes in the environment.
