Answer:

Bycatch can negatively affect species such as dolphins, sea turtles, protected fish, and whales by harming animals, contributing to population declines, and impeding population recovery. Other impacts of fisheries on marine mammals may include removal of their preferred prey and sometimes habitat damage.

Answer:

1. 58.5g/mol

2. 261g/mol

3. 158g/mol

4. 71g/mol

5. 44g/mol

Explanation:

The molar mass of a compound is the total mass of the sum of masses of all individual elements that make up the compound. First, we need to know the atomic masses of each element in a compound.

1. NaCl

Where; Na = 23, and Cl = 35.5

Molar mass of NaCl = 23 + 35.5

= 58.5g/mol

2. Ba(NO3)2:

Where; Ba = 137, N = 14, O = 16

Molar mass of Ba(NO3)2: 137 + {14 + 16(3)} 2

137 + (14 + 48)2

137 + (62)2

137 + 124

= 261g/mol

3. K(MnO4)

Where; K = 39, Mn = 55, O = 16

Molar mass of KMnO4 = 39 + 55 + 16(4)

= 94 + 64

= 158g/mol

4. Cl2

Where; Cl = 35.5

Molar mass of Cl2 = 35.5(2)

= 71g/mol

5. CO2

Where; C = 12, O = 16

Molar Mass of CO2 = 12 + 16(2)

= 12 + 32

= 44g/mol

Answer:

Energy

Explanation:

As waves move from one place to another, they carry energy. Generally, the medium itself doesn't move much as it is the disturbance that is being transmitted

Answer:

Explanation:

Los orbitales híbridos se obtienen mediante una combinación de orbitales atómicos.

En un átomo de carbono con hibridación sp3, el átomo de carbono es tetraédrico con un ángulo de enlace de 109,5 grados. Se pueden unir cuatro enlaces simples al átomo de carbono. Se pueden unir un total de cuatro átomos al carbono. Se puede unir un total de cuatro átomos al carbono, lo que ocurre en alcanos como el metano

Para un átomo de carbono con hibridación sp2, hay dos enlaces dobles y dos enlaces simples unidos al átomo de carbono que tiene una geometría plana trigonal con un ángulo de enlace de 120 grados. Se pueden unir un total de dos átomos al carbono. Se pueden unir un total de dos átomos al carbono. Esto ocurre en alquenos como el eteno.

Un átomo de carbono con hibridación sp tiene un ángulo de enlace de 180 grados y tiene una geometría lineal con un enlace triple y un enlace sencillo. Solo se puede unir un átomo al carbono. Esto ocurre en alquinos como el etino.

Answer:

We know that 18 g of H2O contains 1 mole (or 6.022 x 10^23) molecules of water because the molar mass of H2O is 18 g/mol.

So 1 g water will contain 1/18 moles of H2O molecules.

Now 15 g of water will contain 15/18 moles of H2O.

So molecules of H2O = (15/18) x 6.022 x 10^23 = 5 x 10^23 molecules.

Answer: Stomata allow CO2 to diffuse and can close to minimize water loss. Liverwort pores allow gas exchange and cannot be closed if conditions become dry.

Explanation:

In the kingdom plantae, the liverworts belong to the phylum Bryophyta. A liverwort has a simple structure, ribbon- like body, that lies flat on the ground and is attached to the soil by many rhizoids. They grow in damp places on land and are capable of controlling gaseous exchange through the pores found on their leaf surfaces. Liverworts are non- vascular plants therefore they lack stomata. Unlike the stomata of vascular plants which close in dry weather, the air pores of liverworts remain open all the time. Liverworts cannot control their water loss (transpiration) through the pores.

Stomata are found in the epidermal layer of leaves in vascular plants. The opening and closing of stomata, through the help of the guard cells, control the flow of gases in and out of the leaves. This control is necessary to prevent excessive loss of water as vapour from the plant body throughout transpiration. Changes in the solute concentration of the guard cells cause water to flow in and out of the leaf epidermal cells.

Therefore, to COMPARE the stomata with pores of liverworts, they both allow gaseous exchange but in CONTRAST, stomata has the ability to control water loss as it can open and close while the pores lack this ability.

Answer: The volume of the gas is 1.98 L.

Explanation:

To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]

where,

[tex]V_1\text{ and }T_1[/tex] are the initial volume and temperature of the gas.

[tex]V_2\text{ and }T_2[/tex] are the final volume and temperature of the gas.

We are given:

[tex]V_1=2.2L\\T_1=30^oC=(30+273)K=303K\\V_2=?\\T_2=0^0C=(0+273)K=273K[/tex]

Putting values in above equation, we get:

[tex]\frac{2.2}{303}=\frac{V_2}{273}\\\\V_2=1.98L[/tex]

Thus the volume of the gas is 1.98 L

The statement that describes a hydrogen bond is the bond between hydrogen in one water molecule and another hydrogen in a different water molecule. The correct option is b.

Hydrogen bonds are the bonds that are formed between water molecules and other molecules that join with hydrogen. These are weak bonds. This bond is formed between hydrogen atoms and other atoms.

One of the bonds that allow molecules to associate is the hydrogen bond. It happens when hydrogen forms a covalent bond with an element that is extremely electronegative, such as oxygen, nitrogen, or sulfur.

Thus, the correct option is b) the bond between hydrogen in one water molecule and another hydrogen in a different water molecule.

Answer:

Explanation:

The main reason is because they have different energy in the photon and different wavelength.

In the electromagnetic radiations, radio waves have little energetic photons, micro wave have more that radio waves, the visible light, ultraviolet x Ray's, and gamma Ray's have more energetic photons. They have different wavelength. The shorter the wavelength, the higher the frequency. Wavelength decreases while frequencies increases.

Answer:

480 mL

Explanation:

15L  of  0.38M of NH3(aq.) means that we require 15x0.38 moles of NH3.

Where V is volume in Liters.

These are equal  

⇒15M x V = 15x 0.48
