What can you conclude about the relationship between height and energy?
Answer:
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.
what is density/ how does density work
help help
Answer:
Density is the measurement of how tightly a material is packed together. It is defined as the mass per unit volume. Density Formula: ρ = m/V, where ρ is the density, m is the mass of the object and V is the volume of the object.
Explanation:
Answer:
The mass per unit volume of a substance is called density of that substance.
Explanation:
So, How does it works ?
For example: Density of gold is 19300kg/cubic meter. It means that if there gold having volume of a cubic meter its mass will be 19300 kg... Density of plastics are less than that of density of metals... I.e. if we take plastic having volume 2 cubic meter & gold having volume 1 cubic meter we will find mass of gold is far more compared to that of plastic.. Thus, density refers how much tightly the molecules of a substance are bonded together.
The percentage of water vapor present in the air compared to that required for saturation is the ____.
Answer:
30%
Explanation:
The relative humidity is the water-vapor content of the air relative to its content at saturation. Saturated air, for example, has a relative humidity of 100 percent, and near the Earth, the relative humidity very rarely falls below 30 percent.

The solubility of a gas is 0.890 g/L at a pressure of 120 kPa. What is the solubility of the gas if the pressure is changed to 100 kPa, given that the temperature is held constant?
For the solubility of a gas is 0.890 g/L at a pressure of 120 kPa, the solubility of the gas, if the pressure is changed to 100 kPa is mathematically given as
c=0.741g/l
What is the solubility of the gas if the pressure is changed to 100 kPa, given that the temperature is held constant?Generally, the equation for the Pressure is mathematically given as
p=kc
Therefore
k=p/c
k = 120 /0.890
k=134.8
In conclusion, if p=100kpa

Consider the following oxidation-reduction reaction: 2fe3+(aq) + 2hg(l) + 2cl−(aq) → 2fe2+(aq) + hg2cl2(s). indicate the oxidizing agent and the reducing agent.
Answer:
The reducing agent is Hg (mercury) and the oxidixing agent is Cl (chlorine)
Explanation:
first find the oxidation charges of each of the different ions. All elements that are alone have a charge of 0. As you compare the reactants and products we can see that the chargers of Hg and Cl have changed.
Hg went from a charge of 0 to a charge of +1
Cl went from a charge of 0 to a charge of -1
remember when a substance gains electrons it is reducing and when a substance is losing electrons it is oxidizing.

Why is innate immunity referred to as nonspecific?
because it provides a built-in mechanism of defense that does not require "training"
because it is a form of defense found in all animal species
because it is a form of defense that functions in all human body systems
because it provides defense against a wide range of pathogens
Answer:
c
Explanation:
The innate immune system is the body's first line of defense against germs entering the body. It responds in the same way to all germs and foreign substances, which is why it is sometimes referred to as the "nonspecific" immune system
The attraction forces between mercury atoms in liquid mercury are stronger than the intermolecular forces between water molecules. which of the following is most likely true about mercury? it has a higher surface tension than does water. it exhibits greater capillary action than does water. it is very soluble in water.
The attraction forces between mercury atoms in liquid mercury are stronger than the intermolecular forces between water molecules because it has a higher surface tension than does water.
What is surface tension?Surface tension is the propoerty of the surface of liquids by which they will shrink into the minimum possible surface area.
Surface tension of the liquid mercury is greater than the surface tension of water means cohesive attraction force between the molecules of mercury is greater than water molecules.

If you have a closed container that has a pressure of 2.35atm, and a volume of 1.2L, and contains 76.33g Cl2, what is the resulting temperature in K
The resulting temperature of a closed container that has a pressure of 2.35atm, and a volume of 1.2L, and contains 76.33g Cl2 is 31.8K.
How to calculate temperature?The temperature of a given gas can be calculated by using the ideal gas law equation:
PV = nRT
Where;
P = pressure V = volume n = number of molesR = gas law constantT = temperatureno of moles of Cl2 = 76.33g ÷ 70.91g/mol = 1.08mol
2.35 × 1.2 = 1.08 × 0.0821 × T
2.82 = 0.088T
T = 2.82/0.088
T = 31.8K
Therefore, the resulting temperature of a closed container that has a pressure of 2.35atm, and a volume of 1.2L, and contains 76.33g Cl2 is 31.8K.

Sodium combines with water to produce sodium hydroxide and hydrogen gas. which word equation represents this violent reaction? sodium hydroxide water right arrow. sodium hydrogen sodium water right arrow. sodium hydroxide hydrogen sodium hydrogen right arrow. sodium hydroxide water sodium sodium hydroxide right arrow. water hydrogen
Answer:
B.) sodium water right arrow. sodium hydroxide hydrogen
Explanation:
Reactants are listed before the arrow and products are listed after the arrow. This symbolizes the reactants turning into the products.
Reactants --> Products
Reactants are the molecules which react with each other to make new molecules. Since sodium and water are being combined, they are the starting molecules. Products are the molecules made after a reaction occurs. Sodium hydroxide and hydrogen gas are produced, making them the ending molecules. The balanced chemical equation is:
2 Na⁺ (s) + 2 H₂O (l) --> 2 NaOH (s) + H₂ (g)
