Answer: Surface tension has a more complicated effect on capillary pressure: on the one hand, capillary pressure is directly proportional to surface tension. High surface tension liquids, on the other hand, typically have higher contact angles, which lowers capillary pressure.

What are three ways that the climatic factors of temperature and
sture affect rate of weathering?
Answer:
Generally, interactions with air, water and living organisms cause the weathering of rocks. Although there are two major types of weathering processes, physical weathering and chemical weathering cannot be separated, and they often work together at different rates to break large rocks into smaller pieces over time.

The 5000 kilogram truck
Explanation:
The 5000 kilogram truck is using less force to move vs the 10000 kilogram truck because 5000 kilogram truck is lighter and so needs half the speed as the 10000 kilogram truck.
when an electron moves from a higher orbit to a lower one does it always follow the same path explained
Yes, electron follows the same path when it absorb and loses energy.
Yes, when an electron moves from a higher orbit to a lower orbit it always follow the same path as it moves from a lower orbit to a higher orbit. When electron absorb energy it has the power to move from lower orbit to higher orbit or energy level.
While on the other hand, when an electron loses that energy, it comes back to its original position from which it moves earlier when it absorb energy so we conclude that electron follows the same path when it absorb and loses energy.

how toxic is uranium
Answer:
Inhaling large concentrations of uranium can cause lung cancer from the exposure to alpha particles. Uranium is also a toxic chemical, meaning that ingestion of uranium can cause kidney damage from its chemical properties much sooner than its radioactive properties would cause cancers of the bone or liver.

An environmental chemist analyzed the effluent (the released waste material) from an industrial process known to produce the compounds carbon tetrachloride (CC14) and benzoic acid (HC7H5O2), a weak acid that has one acidic hydrogen atom per molecule. A sample of this effluent weighing 0.3518 g was shaken with water, and the resulting aqueous solution required 10.59 mL of 0.1546 M NaOH for neutralization. Calculate the mass percent of HC7H5O2 in the original sample.
The mass percent of benzoic acid in the sample is 55.5%.
The equation of the reaction is; HC7H5O2(aq) + NaOH(aq) ----> NaC7H5O2(aq) + H2O(l)
Number of moles of NaOH reacted = concentration × volume
Number of moles of NaOH reacted = 10.59/1000 L × 0.1546 M
Number of moles of NaOH reacted = 0.0016 moles of NaOH
Since the reaction is 1:1, 0.0016 moles of HC7H5O2 reacted also.
Hence, mass of HC7H5O2 = 0.0016 moles × 122 g/mol = 0.1952 g
Mass percent of HC7H5O2 in the original sample = 0.1952 g/ 0.3518 g × 100 = 55.5%

Consider a hypothetical gas which has the following Van der Waals constants:
a = 2.34 L2 bar mol-2
b = 0.0 L mol-1
Under conditions of very high pressures, what would you predict about the experimental volume of the gas?
The volume would be lower than predicted by the Ideal Gas Law
The volume would be higher than predicted by the Ideal Gas Law
The volume would be exactly the same as predicted by the Ideal Gas Law
Under conditions of very high pressures, the volume would be lower than predicted by the Ideal Gas Law.
According to the kinetic theory of gases, a gas spreads out to fill the volume of the container holding it. Hence a gas does not have a definite volume due to the fact that there is no inter-molecular interaction between gas molecules.
When the gas is subjected to very high pressure, inter-molecular interactions become significant leading to a decrease in the volume of the gas.
Therefore, when subjected to high pressure, the experimental volume would be lower than predicted by the Ideal Gas Law.

Answer:
A
Explanation:
Its a becuse vinegar and baking soda make carbon dioxide
The equation best models the reaction of vinegar (C2H4O2) and baking soda (NaHCO3) -
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2
The overall process can be summarized by the following word equation:
baking soda (sodium bicarbonate) reacts with vinegar (acetic acid) that yields carbon dioxide and water with sodium acetateThe chemical equation for the overall reaction is:NaHCO3 (s) + CH3COOH (l) → CO2(g) + H2O (l) + NaC2H3O2
The chemical reaction actually occurs in two steps. there is a double displacement reaction in which acetic acid in the vinegar reacts with sodium bicarbonate to form sodium acetate and carbonic acid: NaHCO3 + HC2H3O2 → NaC2H3O2 + H2CO3 Carbonic acid is unstable and undergoes a decomposition reaction to produce the carbon dioxide gas:H2CO3 → H2O + CO2
Thus, the equation best models the reaction of vinegar (C2H4O2) and baking soda (NaHCO3) -
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2

A lunar eclipse can occur only at full moon.
Explanation:
During a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. A total lunar eclipse occurs when the Moon and Sun are on opposite sides of Earth. A partial lunar eclipse happens when only part of Earth's shadow covers the Moon.
Answer:
"Full moon"
A full moon would be needed due to the fact that the sun would need to entirely block it, resulting in a solar eclipse. Hence, the answer is "Full moon".

Liquid octane CH3(CH2)6CH3 will react with gaseous oxygen O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. Suppose 3.43 g of octane is mixed with 7.0 g of oxygen. Calculate the maximum mass of water that could be produced by the chemical reaction. Round your answer to significant digits.
Answer:
88 gram is the answer in 2 significant digits
One mole of octane gives 9 moles of water. Then, 3.43 g or 0.03 moles of octane will give 0.27 moles of water that is 4.86 g of water can be produced.
What is combustion reaction ?Combustion is a type of chemical reaction in which a gas reacts with oxygen to give carbon dioxide and water.
The combustion reaction of octane is given as follows:
[tex]\rm C_{8}H_{18} + \frac{25}{2}O_{2} \rightarrow 8CO_{2} + 9 H_{2}O[/tex]
As per this balanced chemical equation, one mole or 114 g of octane gives 9 moles of water.
no.of moles in 3.4 g of octane = 3.4 g/114 g = 0.03 moles.
no.of moles of water produced from 0.03 moles of octane :
= (0.03 × 9) = 0.27 moles.
Molar mass of water = 18 g/mol
then, mass of 0.27 moles = 0.27 × 18 =4.86 g.
Therefore, the maximum mass of water that could be produced here is 4.86 g.
