What will increase the turgor pressure in a plant

Answer:

0.1 M molar NaaOH

Explanation:

M1V1= M2V2

M1 = 0.150M NaOH

V1=100 ml

V2=150 ml

M2=?

M2= M1V1/V2

M2= 0.150*100/150=0.1 M

Answer:A

Explanation:

Answer:

n chemistry and physics, activation energy is the energy that must be provided to compounds to result in a chemical reaction.The activation energy (Eₐ) of a reaction is measured in joules per mole (J/mol), kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol). Activation energy can be thought of as the magnitude of the potential barrier (sometimes called the energy barrier) separating minima of the potential energy surface pertaining to the initial and final thermodynamic state. For a chemical reaction to proceed at a reasonable rate, the temperature of the system should be high enough such that there exists an appreciable number of molecules with translational energy equal to or greater than the activation energy. The term Activation Energy was introduced in 1889 by the Swedish scientist Svante Arrhenius.

Explanation:

Answer:

The activation energy for the forward reaction is the amount of free energy that must be added to go from the energy level of the reactants to the energy level of the transition state. The source of activation energy is typically heat, with reactant molecules absorbing thermal energy from their surroundings.

Explanation:

Step 1: Define

5.3 mol CaCl₂

Step 2: Identify Conversions

Molar Mass of Ca - 40.08 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar Mass of CaCl₂ - 40.08 + 2(35.45) = 110.98 g/mol

Step 3: Convert

Answer:

375 grams

Explanation:

The percent yield if 155 grams of calcium carbonate is treated with 250 grams of hydrochloric acid and 142 grams of calcium chloride is obtained is 82.55%

Percent yield is defined as the amount of product actually made compared with the maximum calculated yield. It is the ratio of actual yield to the theoretical yield.

Mass of calcium carbonate = 155 g

Mass of HCl = 250g

Mass of calcium chloride product = 142 g

Moles of calcium carbonate = 155 / 100 = 1.55 moles

Moles of HCl = 250 / 36.5 = 6.85 moles

Mass of calcium chloride = Moles x Molar mass

                                          = 1.55 mole x 111 g/ mole

                                          = 172 g /mole

Theoretical yield = 172 g

Actual yield = 142 g

Percent yield = Actual yield / Theoretical yield x 100
                      = 142 / 172 x 100

                      = 82.55 %

Thus, the percent yield if 155 grams of calcium carbonate is treated with 250 grams of hydrochloric acid and 142 grams of calcium chloride is obtained is 82.55%

Dalton's atomic theory was proposed by John Dalton in 1803. It states that elements are made up of indivisible atoms, atoms of the same element are identical, and atoms cannot be created or destroyed.

Dalton proposed that the concept of atoms might be used to explain the laws of definite proportions and the conservation of mass. In his theory, atoms—which he described as "solid, massy, hard, impenetrable, moving particle(s),"—are the minuscule, indivisible units that make up all matter.

It is significant to highlight that Dalton had no knowledge of the potential existence of interior structure in atoms because he lacked the tools necessary to observe or perform further experiments on individual atoms. In a molecular modeling kit, where the various components are represented by spheres of various sizes and hues, we may imagine Dalton's atom as a component. We now know that atoms are not solid spheres, despite the fact that this paradigm is useful in some situations.

They all share genetic information as DNA, shaping their unique traits and functions through evolutionary processes.

Option (A) is correct.

The similarity among a peacock, a jellyfish, and a birch tree lies in the fact that they all share genetic information encoded in their DNA. Genetic information is the blueprint that determines an organism's traits, functions, and characteristics. Despite their diverse appearances and habitats, all living organisms, including these three examples, utilize DNA to carry hereditary instructions.

However, it's important to note that while they share genetic information, the way this information is expressed and the specific traits it codes for differ significantly among these organisms due to variations in their evolutionary history, adaptations, and environmental interactions.

i did the test and got da epic 100 score

A 36.0 g sample of metal was heated from 0°C to 55.0°C. It absorbed 150 J of energy as heat then the specific heat of this piece of metal is 0.0758 J/g.°C  .

The term "specific heat" refers to the amount of energy needed to raise a substance's unit mass by one degree Celsius. This can be mathematically stated as:

q = m×c×ΔT,

where ,

q = the amount of heat

m = the mass of the substance

c = the respective substance's specific heat;

ΔT = the change in temperature.

So, if we want to determine the units for specific heat, we'll just isolate the term in the above formula to get

c = q / m × ΔT                    ( i )

Since heat is measured in Joules ( J ) , mass in grams ( g ) , and temperature in degree Celsius , we can determine that specific heat capacity from equation ( i )  by putting all the given data in this equation ,

c =  150 J / 36.0 g × 55.0 °C = 150 J / 1980 g.°C = 0.0758 J/g.°C

Therefore, specific heat is measured in Joules per g times degree Celsius.
