Answer:

Reflection is like a mirror, you see yourself in the mirror thats your reflection, or you see yourself in a puddle. Basically a reflection just absorbed light.

On the asexual reproduction your supposed to drag down facts about it from above into its circle.

same thing for the sexual reproduction.

on the middle you're supposed to put it the things that asexual reproduction and sexual reproduction have in common or the same.

I hope this helps

please mark this as brainiest!

The volume occupied by 1.5 mole of gas at 35°C and 2.0 atmosphere of pressure is blank liters

Aneli [31]

Answer: 18.97 L

Explanation:

This can be solved by the Ideal Gas equation:

$P.V=n.R.T$

Where:

$P=2 atm$ is the pressure of the gas

$V$ is the volume of the gas

$n=1.5 mole$ the number of moles of gas

$R=0.0821\frac{L.atm}{mol.K}$ is the gas constant

$T=35\°C+273.15=308.15 K$ is the absolute temperature of the gas in Kelvin

Finding $V$ :

$V=\frac{nRT}{P}$

$V=\frac{(1.5 mole)(0.0821\frac{L.atm}{mol.K})(308.15 K)}{2 atm}$

$V=18.97 L$

Therefore:

The volume occupied by 1.5 mole of gas at 35°C and 2.0 atmosphere of pressure is 18.97 liters

Which of the following conditions will ensure that a chemical reaction will definitely proceed in the forward direction, toward

Grace [21]

Answer:

When ΔS > ΔH/ T, then the reaction will proceed forward

Explanation:

The entity that determines the whether a reaction will occur on its own in the forward direction (Spontaneity or Feasibility) is Gibb's free energy.

Gibb's free energy is the energy available to do work. It is denoted as 'G'. It cannot be easily measured. The change (ΔG) can only be measured. ΔG = ΔH - TΔS

when ΔG is positive, The reaction is not spontaneous (reaction will not occur on its own)

When ΔG is negative, The reaction is spontaneous (reaction will occur on its own)

When ΔG is zero, the reaction is in equilibrium

Option A and E are not correct. ΔH (Enthalpy) cannot determine spontaneity

Option C and D cannot alone determine spontaneity of reaction

For reaction to be spontaneous, TΔS > ΔH

Therefore, ΔS > ΔH/T

Which result occurs during an exothermic reaction?(1 point)

vekshin1

The result which occurs during an exothermic reaction is: C. Light and heat are released into the environment.

A chemical reaction is defined as a chemical process involving the continuous transformation and rearrangement of either the ionic, atomic or molecular structure of chemical elements, especially through the breakdown and formation of chemical bonds, so as to produce a new chemical compound.

Basically, the two (2) main types of chemical reaction are;

Endothermic reaction: this is a chemical reaction in which heat is absorbed .

Exothermic reaction: this is a chemical reaction in which light and heat is liberated (released) into the environment.

In an exothermic chemical reaction, light and heat energy is liberated (released) when the energy of the products is lesser than the energy of the reactants.

In conclusion, light and heat is liberated (released) into the environment during an exothermic reaction.
