1. You are pushing a heavy shopping cart full of water bottles with a constant force. The shopping cart has
mass of 250 kg and it is accelerating down the aisle at 0.20 m/s? How much force are you exerting?
Answer:
F = 50 N
Explanation:
Given data:
Mass of car = 250 Kg
Acceleration of car = 0.20 m/s²
Force required = ?
Solution:
Formula:
F = m×a
F = applied force
m = mass
a = acceleration
Now we will put the values in formula.
F = 250 Kg × 0.20 m/s²
F = 50 Kg.m/s²
Kg.m/s² = N
F = 50 N

SEP Engaging in Argument Use the phase diagrams for CO2 and H2O in the Experience Notebook. Theaters sometimes use dry ice (solid CO2) to produce dense clouds of smoke like fog on stage. A classmate claims that the phase diagrams of H2O and CO2 show that it would not be practical to use H2O for this purpose. Do you agree with the classmate’s claim? Cite reasons to support your argument.
Answer:
Agree (see explanation)
Explanation:
I do agree with this statement of practicality. According to my research and viewership of phrase diagrams for both substances, water enters a similar form of “smoke” or “steam” at incredibly hot temperatures usually secluding to temperatures of over 200 degrees Fahrenheit (100 degrees Celsius) versus carbon dioxide of which enters this state at room temperature (60-70 degrees Fahrenheit). In order for either of these events to occur in this form, both must undergo procedures of sublimation where solids transfer directly from solids to gases, skipping the liquid state. Water contains ionic hydrogen bonds of which are incredibly strong particle arrangements, therefore requiring much higher temperatures to divide and individualize these particles forming high pressure and kinetic energy. Since carbon dioxide is formed of covalent bond ship, the intermolecular forces are relatively weak making the process of sublimation quite instant when this substance experiences exposure to specific temperatures, typically temperatures that we consider “normal”.

Choose the mole ratio below that is INCORRECT based on the given balanced equation:
2 C2H5OH + 7 O2 --> 4 CO2 + 6 H2O
O 2 moles C2H5OH = 4 moles CO2
O 7 moles O2 = 2 moles C2H5OH
O 4 moles CO2 = 4 moles O2
O 6 moles H2O = 7 moles O2
Answer:
4 moles CO₂ = 4 moles O₂
Explanation:
The reaction equation is given as;
2C₂H₅OH + 7O₂ → 4CO₂ + 6H₂O
The incorrect mole ratio from the relationships shown is;
4 moles CO₂ = 4 moles O₂
Number of moles of CO₂ = 4
Number of moles of O₂ = 7
So, the right expression is;
4 moles CO₂ = 7 moles O₂

You have a flexible helium balloon filled with 0.100 mol of gas that is 2.10 L at a certain temperature and pressure. If you deflate the balloon at, constant temperature and pressure, so that it is now only 0.700 L, how many mol of gas are remaining in the balloon?
Answer:
0.033 mole
Explanation:
The following data were obtained from the question:
Initial mole (n1) = 0.1 mol
Initial volume (V1) = 2.1 L
Final Volume (V2) = 0.7 L
Final mole (n2) =?
Since the temperature and pressure is constant, then the number of mole remaining in the balloon can be obtained by using the following formula as illustrated:
V1 /n1 = V2 /n2
2.1/0.1 = 0.7/n2
21 = 0.7/n2
Cross multiply
21 × n2 = 0.7
Divide both side by 21
n2 = 0.7/21
n2 = 0.033 mole
Thus, 0.033 mole of the gas is remaining in the balloon.

can you identify an atom without knowing numbers of neutrons in it?
Answer:
No
Explanation:
We cannot identify an atom without knowing numbers of protons in the atom.
The number of neutrons is the amount of neutrally charged particles in an atom. These subatomic particles occupy the dense nucleus with the protons.
To determine an atom, we use their atomic numbers. Atomic number is the number of protons in an atom. Protons are the positively charged particles in the atom. The periodic table of elements is arranged by the atomic number of an element.Which of the following refers to all of the organisms in a particular area?

How many kilojoules of heat energy are absorbed when 98.5 g of water are heated from 24.5 oC to 48.8 oC?
Answer:
10.01461 kilojoules of thermal energy are absorbed when 98.5 g of water is heated from 24.5 ° C to 48.8 ° C
Explanation:
Sensible heat is the amount of heat that a body absorbs or releases without any changes in its physical state (phase change) causing a change in temperature.
The equation that allows to calculate heat exchanges in this case is:
Q = c * m * ΔT
where Q is the heat exchanged by a body of mass m, constituted by a substance of specific heat c and where ΔT is the change in temperature.
In this case:
c=4.184 [tex]\frac{J}{g*C}[/tex]m= 98.5 gΔT= Tfinal - Tinitial= 48.8°C - 24.5°C= 24.3 °CReplacing:
Q= 4.184 [tex]\frac{J}{g*C}[/tex] *98.5 g* 24.3 °C
Solving:
Q=10,014.61 J
Since 1 J is equal to 0.001 kJ, then you can apply the following rule of three: if 1 J is equal to 0.001 kJ, then 10,014.61 J is equal to how many kJ?
[tex]kJ=\frac{10,014.71 J*0.001 kJ}{1 J}[/tex]
kJ=10.01461 kJ

Answer:
1. Dune
2. Glaciers
3. Loess
4. Glacial drift
5. Glaciers deposit their sediment when they melt. They drop and leave behind whatever was once frozen in their ice. It's usually a mixture of particles and rocks of all sizes, called glacial till.
6. Large plants like shrubs and trees break the wind. Compare and contrast how wind and glaciers abrade rocks. Both move rock materials past each other. The materials moved by wind are very small, wheres they are glaciers they can abrade a large rock.
7. A mass movement can either be slow or rapid. The slow downward movement of materials in a slope is called creep. This happens when the soil loosens up because of water and burrowing animals. In contrast to this, the rapid movement of large materials in a slope is called landslide.

The Law of Superposition allows us to determine:
a
which rock layers are the oldest
b
the relative age of layers of rocks and the fossils in them
c
the exact or absolute age of rock layers
d
a and b are correct
Answer:
d . a and b are correct
Explanation:
The law of superposition allows us to determine the age of rock layers and also that of the fossils within them.
The law of superposition states that "in an undeformed sequence of strata, the oldest rock layer is at the bottom and the youngest is on top".
Using this law, geochronologists can determine the relative ages of rock layers. The youngest layer will be found on top. The oldest at the bottom of the sequence. The arrangement of the layers and the fossils there in can also tell us about the ages of the fossils themselves.On a hot day, Ava got herself a carbonated beverage. She knew from her science class that carbonated drinks had carbon dioxide in them.
She noticed that bubbles started to form and rise upwards only after she unscrewed the cap. She then opened another bottle that was much colder and she noticed fewer bubbles had formed. Explain what Ava observed. PLS ANSWER, I NEED HELP !!
Explanation:
Using a derivative of the combined gas law we can explain what is happening in both instances.
Assuming that the volume is constant which is predicated on the bottle shape and structure, the pressure of a given mass of gas varies directly with the absolute temperature.
As temperature increases, the pressure also increases and vice versa.
The first bottle at a higher temperature has a higher pressure of gas. The second bottle at a lesser temperature has a reduced pressure inside.
