levacccp [35]3 years ago
7 0

Answer:

294000 J or 294 kJ

Explanation:

Potential energy is given by:

U=mgh

Where U is potential energy, m is mass, g is acceleration due to gravity, and h is height. Using this equation:

U=100(9.8)(300)\\U=294000

Ill give brainliest if you answer right
Paraphin [41]

Answer:

It'll be the same as 58.44 amu. This is because of the law of conservation of mass which states that total mass of reactants is always equal to the total mass of products formed.

If a solution containing
tankabanditka [31]

Answer:

Hg(NO₃)₂(aq) + Na₂SO₄(aq)   →   2NaNO₃(aq) + HgSO₄(s)

Moles of Hg(NO₃)₂ = 55.42 / 324.7 ==> 0.1707 moles

Moles of Na₂SO₄ = 16.642 / 142.04 ==> 0.1172 moles

Limiting reagent is Na₂SO₄ as it controls product formation

Moles of HgSO₄ formed = 0.1172 moles

                                        = 0.1172 x 296.65

                                        = 34.757g

givi [52]

Answer:

increase the rate of a reaction without being consumed by the reaction

Explanation:

  • Enzymes are biochemical catalysts that increase the rate of chemical reactions.
  • They increase the rate of a chemical reaction without being consumed by the reaction.
  • Enzymes increase the rate of chemical reactions by decreasing the activation energy of the reactants.
  • Catalysts such as enzymes do not affect the free energy change of a chemical reaction (delta G). Therefore, delta G for a catalyzed and non-catalyzed reaction is equal.

How much is a mole in chemistry? Like the mathematical term.
Svetach [21]
Well on a side note, a mole in chemistry is also the same as a Liter. A mole however, is the mass of an element,or compound. 1 mol of O would be 15.9994 grams/mol. It can also be represented as 6.022*10 to the 23 power. (1 mol of Carbon-12 atoms)
