Slower
Explanation:
A liquid starts changing its phase to gas when the two pressures become the same i.e., vapor and atmospheric.
At a higher altitude the atmospheric pressure lowers so little amount of heat is required for the vapor pressure of water to equalize with the atmospheric pressure at a higher altitude.
The pressure at the Rosa's home will be higher and lower in the campsite.
The boiling point will be higher at her home.
As the boiling point is lower in the campsite the water used in cooking noodles will evaporate faster this may lead to the noodles being under cooked. The water may evaporate before the noodles have cooked. So, the noodles will cook at a slower rate at the campsite and faster in her home.
A. The atmospheric pressure at Rosa's home is higher than her campsite.
B. The boiling point of water at Rosa's home is higher.
C. The noodles will be cooked faster at Rosa's home compared to at the campsite
A. The pressure has been the force that has been exerted by the molecules against each other, The higher altitude has lesser air molecules, which resulted in the lower pressure.
Since the pressure at 33 feet has been higher as than the pressure at 11,000 feet altitude, the atmospheric pressure at Rosa's home is higher than her campsite.
B. The boiling point has been the temperature at which liquids have been converted to gases. With the decrease in atmospheric pressure, there has been a lowering in the boiling point as well.
The atmospheric pressure at Rosa's home is higher compared to her campsite. Thus, the boiling point of water at Rosa's home is higher.
C. The lower atmospheric pressure at the campsite has been responsible for the lower boiling point of the temperature, This implies that water has converted to steam at lower temperatures. The lower temperature of water requires more time for the noodles to be cooked.
Thus, the noodles will be cooked faster at Rosa's home compared to at the campsite.

When 50.0 mL of 1.000 M HCl is reacted with 50.0 mL of 1.000 M NH4OH, the solution's temperature increases 8.65 °C. Calculate qsolution in units of kJ. The specific heat of the salt solution is 4.184 J/g-°C and the density is 1.010 g/mL.
Answer:
Explanation:
Total volume of solution = 100 mL .
Total mass of the solution = 100 x 1.01 g
= 101 g
specific heat of solution = 4.184 J/g-°C
rise in temperature = 8.65 °C
heat released = mass x specific heat x rise in temperature
= 101 x 4.184 x 8.65
= 3655.35 J
= 3.655 kJ .
qsolution = 3.655 kJ .
Which of an atom's electrons are inrolved in chemical reactions?
Answer:
Electrons at the outermost energy level of an atom are called valence electrons. They determine many of the properties of an element. That's because these electrons are involved in chemical reactions with other atoms. Shared electrons bind atoms together to form chemical compounds.

Why do electronegativity charts often give no values to the group 18 elements?
Answer:
Because they have complete electronic configuration
Explanation:
Group 18 elements are known as the noble or inert gases. The elements in this group are non-reactive because they have complete electronic shell configuration.
Electronegativity is the tendency of an atom to attract electrons. The reason why atoms attracts electrons is to have a stable configuration like those of the noble gases. Since the noble gases do not require any extra-electrons to attain stability, they have 0 electronegative values.The digestive system is a group of organs working together to...

Answer:
C. It Will Provide information to help formulate a new hypothesis in the future.
Explanation:
I had AP Chemistry.
The following statement that it will provide information to help formulate a new hypothesis in the future is true about a hypothesis that is proven to be inaccurate.
What is hypothesis?Hypothesis can be defined as an assumption which is made for the sake of argument . It is an interpretation of a practical condition for which action needs to be taken.It is defined as a tentative assumption which is made to test logical consequences.It is an antecedent clause of a statement which is conditional.
It is constructed before research. There are six types of hypothesis 1)simple hypothesis 2) complex hypothesis 3) directional hypothesis 4)non-directional hypothesis 5) null hypothesis 6)casual hypothesis
The hypothesis should be clear and precise, it must be specific and way of explanation of hypothesis should be simple.

what are the similarities and differences between the crocodile , sheep , and gorilla digestive system?
Answer: Crocodile is a reptile whereas sheep and gorilla are the mammals.
Explanation:
Crocodile, sheep, and gorilla have alimentary canal in their digestive system. The urea is the common excretory waste.
Mouth is typically large in case of crocodile and comparatively small in sheep and gorilla.
In crocodile more sharp teeth are present as compared to sheep and gorilla for mastication of food and capturing the prey like fish or large animals like zebra.
The crocodile palate is more stronger than sheep and gorilla because it enable it to chew the bones of the prey.
Given the name of an element and the number of neutrons, find the mass of an Isotope
The given element nitrogen have 7 electrons and 7 protons. Mass number is the sum of number of protons and neutron. The number of neutrons is 7. Thus mass number of the isotope is 14.
What is nitrogen?Nitrogen is 7th element in periodic table. It is an electronegative element and is included in p block. Nitrogen exists as gas but sometime it can be liquified under high pressure.
Isotopes are atoms with same atomic number and different mass number. Nitrogen have two isotopes. N-14 and N-15. Mass number is the sum of number of protons and neutrons.
Even though isotopes are different in mass number their chemical properties will be similar but there exists slight changes in their physical properties.
Here, we have 7 protons and 7 electrons therefore, the mass number 14.Thus the isotope given in the diagram is N-14.

Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there. first question Natural non-living things: They are found in nature and are not made by man. Examples: Sun, moon, stars, sky, clouds, rocks, mountains and many more. Man-made non-living things: They are made by man. Examples: Toys, chairs, tables, beds, houses, buildings, trains and many more. second question Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock.

If I place a balloon in my fridge that initially has a pressure of 1.02 atm and a
temperature of 11.2 °C, what will be the pressure (in atm) of the balloon when it is
fully cooled to 4.00°C by my refrigerator?
Answer:
P₂ = 0.99 atm
Explanation:
Given data:
Initial pressure = 1.02 atm
Initial temperature = 11.2°C
Final pressure = ?
Final temperature = 4.00°C
Solution:
Initial temperature = 11.2°C (11.2+273 = 284.2 K)
Final temperature = 4.00°C (4.00+273 = 277 K)
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
1.02 atm / 284.2 K = P₂/277 K
P₂ = 1.02 atm × 277 K / 284.2 K
P₂ = 282.54 atm. K /293 K
P₂ = 0.99 atm
