Explanation:

An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native. ... Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats.

Answer:

True

Explanation:

The Coriolis effect is the deflection of winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere because of Earth's rotation. This statement is true.

Circulating air is deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere as the Earth rotates on its axis. The Coriolis effect refers to this deflection.

Because of the rotation of the Earth, we experience an apparent force known as the Coriolis force. The wind is deflected to the right in the northern hemisphere and to the left in the southern hemisphere as a result of this.

There is no curving of the object's path as measured relative to the Earth's surface because there is no turning of the Earth's surface  underneath a horizontally and freely moving object at the equator.

Thus, There is no Coriolis effect because the object's path is straight.

Answer:The rate of enzyme reaction increases with increase in substrate concentration. Upon saturation of active site of the enzyme with the substrate, there will be no effect on the rate of reaction.

Explanation:

Enzymes are protein molecules secreted by special cells in a living organism. They are organic catalysts responsible for the metabolic reactions that take place in living organisms. Thus, glycolysis, synthesis of proteins and photosynthesis are mediated by numerous enzymes.

Also, enzymes may be classified according to the type of reaction they catalyze. They include: oxidoreductases, transferases, hydrolases, lyases, isomerases, ligases, and translocases.

From the question, catalase enzyme is a type of oxidoreductase enzyme that catalyzes the decomposition of hydrogen peroxide (substrate) into water and molecular oxygen.

The regions on the enzyme into which the substrate molecules fit are known as the ACTIVE SITES of the enzyme.

Substrate concentration is one of the factors that affect enzyme rate of reaction. The enzyme function varies with substrate concentration because the rate of enzyme reaction increases with increase in substrate concentration. Upon saturation of ACTIVE SITE of the enzyme with the substrate, there will be no effect on the rate of reaction.

Difference Between Empirical and Molecular Formulas. The key difference between empirical and molecular formulas is that an empirical formula only gives the simplest ratio of atoms whereas a molecular formula gives the exact number of each atom in a molecule. In chemistry, we often use symbols to identify elements and molecules.

Answer:

312 g of O₂

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

2KClO₃ —> 2KCl + 3O₂

From the balanced equation above,

2 mole of KClO₃ decomposed to 3 moles of O₂.

Next, we shall determine the number of mole of O₂ produced by the reaction of 6.5 moles of KClO₃. This can be obtained as follow:

From the balanced equation above,

2 mole of KClO₃ decomposed to 3 moles of O₂.

Therefore, 6.5 moles of KClO₃ will decompose to produce = (6.5 × 3)/2 = 9.75 moles of O₂.

Finally, we shall determine the mass of 9.75 moles of O₂. This can be obtained as follow:

Mole of O₂ = 9.75 moles

Molar mass of O₂ = 2 × 16 = 32 g/mol

Mass of O₂ =?

Mole = mass / Molar mass

9.75 = Mass of O₂ / 32

Cross multiply

Mass of O₂ = 9.75 × 32

Mass of O₂ = 312 g

Thus, 312 g of O₂ were obtained from the reaction.

Answer:

3.1 × 10² g

Explanation:

Step 1: Write the balanced decomposition reaction

KClO₃ ⇒ KCl + 1.5 O₂

Step 2: Calculate the moles of O₂ formed from 6.5 moles of KClO₃

The molar ratio of KClO₃ to O₂ is 1:1.5.

6.5 mol KClO₃ × 1.5 mol O₂/1 mol KClO₃ = 9.8 mol O₂

Step 3: Calculate the mass corresponding to 9.8 moles of O₂

The molar mass of O₂ is 32.00 g/mol.

9.8 mol × 32.00 g/mol = 3.1 × 10² g

Explanation:

Expression for capillary rise is as follows

h = 2T / ρ g r where T is surface tension , ρ is density of liquid and r is radius of capillary tube.

T = .032 J m⁻²

ρ = .71 g / cm³

= 7100 kg / m³

r = .1 x 10⁻³ m = 10⁻⁴ m

h = 2 x .032 / (7100 x 9.8 x 10⁻⁴ )

h = .0092 m

= 9.2 mm .

Answer:

There are 3 atoms in the 50 moles of Al

Explanation:

Answer:

2.94 × 10²⁴ molecules

Explanation:

Step 1: Given data

Volume of acetone (V): 360 mL (360 cm³)

Density of acetone (ρ): 0.788 g/cm³

Step 2: Calculate the mass of acetone (m)

Density is equal to the mass of acetone divided its volume.

ρ = m/V

m = ρ × V

m = 0.788 g/cm³ × 360 cm³ = 284 g

Step 3: Calculate the moles corresponding to 284 g of acetone

The molar mass of acetone is 58.08 g/mol.

284 g × 1 mol/58.08 g = 4.89 mol

Step 4: Calculate the number of molecules in 4.89 moles of acetone

We will use Avogadro's number: there are 6.02 × 10²³ molecules of acetone in 1 mole of molecules of acetone.

4.89 mol × 6.02 × 10²³ molecules/1 mol = 2.94 × 10²⁴ molecules
