Which population of frogs will best survive a change in the environment?

Answer:

When the batter hits the ball, there is a force applied, and energy is transferred. The ball will move in the direction the force is pushing it. If two objects collide, energy will be transferred between both, and there will be a change in motion.

Answer:

1.276 moles

Explanation:

molar mass of H2SO4 = 2(1)+(32)+4(16) = 98 g

So, there are (125g)(1 mol/98g) = 1.276 moles

1.276 moles are in 125 g of H[tex]_2[/tex]SO[tex]_4[/tex]. A mole is indeed a unit that enables us to correlate the mass of a material with its components.

It is defined as the amount of any material that has the same number of basic units as there are in a precisely measured sample of 12C that weighs 12 g. Latin's word for pile, stack, or assemblage is "mole." The number of entities that make up a mole was discovered via experimentation to be 6.022 X 1023.

A mole is indeed a unit that enables us to correlate the mass of a material with its components. The total of the masses of all the atoms that make up one mole of a molecule, expressed in grams, is what is known also as molecular mass or molar mass. A substance's molar mass may be calculated by multiplying its given mass by its g/mol density.

molar mass of H[tex]_2[/tex]SO[tex]_4[/tex] = 2(1)+(32)+4(16)

                                    = 98 g

mole= (125g)(1 mol/98g)

       = 1.276 moles

Therefore, 1.276 moles are in 125 g of H[tex]_2[/tex]SO[tex]_4[/tex].

Answer:

160.000 años corresponde a 16.000 décadas.

Explanation:

Para resolver correctamente el ejercicio debemos plantear la regla de tres simple de la siguiente manera:

1 década equivale a 10 años; A cuantas decadas equivalen 160.000 años?

1 década→10 años

          x    ←160.000 años

Debemos multiplicar 160.000 por 1 y luego dividir entre 10 ;

x=([tex]\frac{160.000x1}{10}[/tex])=16.000 décadas; en notación científica sería 16x10^3.

Respuesta: 160.000 años corresponde a 16.000 décadas.

Answer:

Synthesis reactions. Decomposition reactions. Combustion reactions.

Explanation:

Synthesis reactions. - Two or more reactants combine to make 1 new product

Decomposition reactions. - A single reactant breaks down to form 2 or more products.

Combustion reactions. - A single element or compound combines with oxygen gas releasing energy. This rapid oxidation is called burning.

PLATO answer

Answer:

1.00 mol

Explanation:

Step 1: Given data

Molecules of water: 6.02 × 10²³ molecules

Step 2: Calculate the number of moles corresponding to 6.02 × 10²³ molecules of water

In order to convert molecules to moles, we need a conversion factor. In this case, we will use Avogadro's number: there are 6.02 × 10²³ molecules in 1 mole of molecules.

6.02 × 10²³ molecules × 1 mol/6.02 × 10²³ molecules = 1.00 mol (we keep 3 significant figures)

Answer:

B) Cations lose electrons having a charge of positive.

Explanation:

Hello there!

In this case, it is widely known that ions are classified as positive cations and negative anions, since the former is produced when a metal loses electrons and the latter when a nonmetal gains electrons; in such a way, the correct choice is:

B) Cations lose electrons having a charge of positive.

Answer:Calcium hydroxide is a polar compound. 2. Carbonates are insoluble in water unless it is combined with NH4+ or any group 1A ion. It is a colorless crystal or white powder and is produced when quicklime (calcium oxide) is mixed, or slaked with water.Ca(OH)2 is an ionic compound, in which Ca is the cation and OH is the anion. Ca (calcium) has a charge of 2+, since it is in group 2 on the periodic table.

Explanation:

Kinetic energy is the energy of movement or energy at work. An example is a ball rolling down a hill.

Potential energy is stored energy due to the position of an object. For example, a ball resting at the top of a hill.

The question incorrectly described potential energy as kinetic energy. Therefore, the answer is false.
