Solubility of Oz in g/100 g water
Temperature in °C
Independent Variable
Dependent Variable
pls helppp asap
Answer:
Temperature - Independent variable
The solubility of CO2 and Solubility of O2 - Dependent variable
Explanation:
There are always two variables in an experiment: Independent and dependent variables.
Independent variables are defined as the variables that can be controlled or changed to measure its effect on the dependent variable and the dependent variable is influenced by the change in Independent variables.
In the given example, the temperature is the Independent variable and the solubility of CO2 and Solubility of O2 is the dependent variable because the solubility of CO2 and O2 decreases as temperature increases.
Hence, the correct answer is:
Temperature - Independent variable
The solubility of CO2 and Solubility of O2 - Dependent variable
What is the pressure, in atm, of 1.0 moles of neon gas in a 5.0 L steel container at a temperature of 291 K?
Answer:
4.78atm
Explanation:
given: v=5L R=0.0821LatmK^-1*291K
n=1mol T=291K
PV=nRT
P= 1mol*0.0821LatmK^-1*291K / 5.0L
=4.78atm

Under the same conditions of temperature and pressure, three different samples of the same uniform shape.
The density of a substance is in intrinsic property. Irrespective of the temperature and pressure or any other condition, the density of a substance will not change.
Mass is the quantity of matter in a substance and it is not affected by the temperature or pressure of the object.
The volume of the a substance changes with change in temperature and pressure but we have been told that these conditions are the same so the volume of the object does not change.
However, if the objects are exactly uniform, at the same temperature and pressure, the objects will have the same shape.

The form of energy stored in the bonds between atoms is _____________energy. This form of energy falls into the _____________energy category.
Answer:
1. chemical 2. potential
Explanation:
energy, potential energy, is stored in the covalent bonds holding atoms together in the form of molecules. This is often called chemical energy.Energy is found in different forms, but all energy falls into the following two categories – potential energy and kinetic energy. Potential energy is stored energy, or the energy of position. It consists of the following forms: Chemical energy is energy stored in the bonds between atoms in molecules.
The form of energy stored in the bonds between atoms is chemical energy. This form of energy falls into the potential energy category.
What is chemical energy ?The term chemical energy is defined as the energy of chemical substances that is released when they are undergo the process of chemical reaction and covert into the another substances.
The chemical energy is used to create heat and electricity along the world. Some peoples also burn these fuels on more minor scales to formed heat to keep buildings warm. They burn fossil fuels like natural gas, oil, and petroleum to produce steam to turn turbines that formed heat and electricity.
The energy stored in chemical bonds is called as chemical energy therefore, it is a form of potential energy. The examples of potential energy are the energy of water present behind a dam.
Thus, The form of energy stored in the bonds between atoms is chemical energy. This form of energy falls into the potential energy category.

graphite conducts electricity but dimond does not .why?
Graphite can conduct electricity because of the delocalised (free) electrons in its structure. These arise because each carbon atom is only bonded to 3 other carbon atoms. ... However, in diamond, all 4 outer electrons on each carbon atom are used in covalent bonding, so there are no delocalised electrons.

An earthquake on the ocean floor produced a giant wave called a tsunami. The tsunami traveled through the ocean and hit a remote island, causing a lot of damage. Is the water that hit the island the same water that was above the earthquake on the ocean floor?
Answer:
Yes
Explanation:
What cause an earthquake is when the earth plates shift and if theirs a drop in the tentonic plates a ripple effect like when you drop something in water will occur. The plates shift down the water in which the plate shift down the water will go in that direction due to gravity, but instead of equalizing the water will pick up some speed and velocity and begin to form a wave now. When an tsunami happens you know it coming cause the water moves back cause the water is picking up to much speed and due to cohesion its moves along with the move water and builds up. Creating a massive tidal wave known as tsunamis.
The water that hit the island is not the same water that was above the earthquake on the ocean floor. Waves transfer energy not matter.
It should be noted that the earthquake on the ocean floor that produces a giant wave referred to as a tsunami is quite different from the water that hits a remote island, causing a lot of damage.It should be noted that waves transfer energy but not matter. While waves are able to transfer energy over a particular distance, it doesn't move the matter along the same distance.For example, it should be noted that an ocean wave is able to travel for several kilometers while the water itself doesn't move.In conclusion, waves transfer energy not matter.

When you get home, you smell cookies baking. You respond by walking toward the kitchen. Many signals move through your
nervous system in this process. Which component is involved first? (1 point)
O axons in your motor neurons
axons in your sensory neurons
Odendrites in your motor neurons
O dendrites in your sensory neurons
Answer:
dendrites in your sensory neurons
Explanation:
Sensory neurons are first activated, then the stimulus is transmitted horizontally between them, spreading perception through the olfactory bulb that captures the smell of a baked cookie.
After this, the axons are activated to transmit to the motor neurons that will carry out the action of walking towards the kitchen.

Which element is malleable and ductile?
○Flourine O Gallium
O Silicon O Phosphorous
Answer:
Gallium
Explanation:
The element that is malleable and ductile is gallium.
Gallium is a metal that exhibits the properties of malleability and ductility.
The ability of a material to be hammered or rolled into thin sheets without breaking or shattering is referred to as malleability. This characteristic of gallium makes it simple to shape or flatten it under pressure without shattering.
Contrarily, ductility describes a material's capacity to be pulled into thin wires without cracking. Gallium is ductile, which means it can be bent into the shape of thin wires without breaking.
Therefore, the correct option is gallium.
