Answer:
44 g CO₂
Explanation:
The chemical equation for the reaction is:
C(s) + O₂(g) → CO₂(g)
Thus, 1 mol of C(s) reacts with 1 mol of O₂. We convert the moles to grams by using the molecular weight of each compound (C= 12 g/mol; O₂= 32 g/mol):
1 mol C(s) = 12 g/mol x 1 mol = 12 g
1 mol O₂= 32 g/mol x 1 mol = 32 g
The stoichiometric ratio C(s)/O₂ is 12 g C/32 g O₂. We have 40 g of O₂, so it will be consumed:
40 g O₂ x 12 g C/32 g O₂= 15 g C(s)
And we have 12 g. Thus, the limiting reactant is C(s).
Now, we use the limiting reactant to calculate the mass of product produced (CO₂)
Molecular weight CO₂ = 12 g/mol x 1 C + (16 g/mol x 2 O) = 44 g/mol
1 mol CO₂ = 44 g/mol x 1 mol = 44 g
So, 44 grams of CO₂ are produced from 12 g of C(s) (44 g CO₂/12 g C). So, the amount produced when 12 g of C(s) reacts with 40 g O₂ is:
12 g C(s) x 44 g CO₂/12 g C(s) = 44 g

A tugboat tows ships out of a harbor. The tugboat starts pulling the ships when they are stopped at a dock.
Masses of ships
Name Mass (kg)
Eden 3,239
Skipjack 2,273
Standard 2,020
Thunderer 2,526
Viceroy 1,859
The tugboat tows with the same force no matter the size of the ship. Order the names of the ships to show the size of the acceleration each ship will have as it starts to move.
Answer:
In order of decreasing acceleration experienced by each ship, the names of the ships are as follows:
Viceroy
Standard
Skipjack
Thunderer
Eden
Explanation:
A force is a push or pull upon an object resulting from the object's interaction with another object.
According to Newton's second law of motion, the acceleration of an object is directly proportional to the resultant (or net) force and inversely proportional to the mass of the object and the acceleration occurs in the same direction as the force.
Mathematically, a = F/m
From the given question, the tugboat tows the ships with the same force no matter the size of the ship, therefore, force is constant. The acceleration each ship will have as it starts to move assuming force = 1 N, is given below:
Eden; mass = 3,239;
acceleration = 1/3239 = 3.09 * 10⁻⁴ m/s²
Skipjack 2,273
acceleration = 1/2273 = 4.40 * 10⁻⁴ m/s²
Standard 2,020
acceleration = 1/2020 = 4.95 * 10⁻⁴ m/s²
Thunderer 2,526
acceleration = 1/526 = 3.96 * 10⁻⁴ m/s²
Viceroy 1,859
acceleration = 1/1859 = 5.38 * 10⁻⁴ m/s²
Thus, in order of decreasing acceleration experienced by each ship, the names of the ships are as follows:
Viceroy
Standard
Skipjack
Thunderer

Many proteins are regulated by the binding of GTP or GDP. Which form is the active state of the protein
Answer:
GTP-bound form
Explanation:
Such a receptor may be associated with the GDP-regulated G-stimulant protein system. When the neurotransmitter binds to the receptor, the protein G-GDP complex is activated by separating its β subunit. When the ligand "sticks" to it, it releases GDP and allows GTP to bind. This form of the G protein that binds GTP, is the activated ("on") form of it. When it is "on" it releases signals into the cell. After a short period (seconds or less) the G protein hydrolyzes the GTP to GDP and itself "turns off".
One tool scientists use to learn about the weather is radar. To use radar, a weather tower sends out radio waves and then detects the waves that are reflected back to the tower. If a great number of radio waves are reflected back from a particular area, what does that tell scientists about the weather in that area? O A. There is a light sprinking of rain in the area. B. There is going to be a drop in air pressure in the area. C. There is only sunshine in the area, with no clouds. O D. There is a large amount of rain or snow in the area.
Answer:
D
Explanation:
heavier rain or snow reflects more radio waves
To use radar, a weather tower sends out radio waves and then detects the waves that are reflected back to the tower There is a large amount of rain or snow in the area.
What is Radar?Radial velocity, azimuth, and distance of objects in relation to the site are all determined using radar, a radiolocation technology, using radio waves.
It is used to map weather patterns and the topography as well as detect and track motor vehicles, guided missiles, ships, airplanes, and spacecraft.
The components of a radar system are a transmitter that generates electromagnetic waves in the radio or microwave spectrum, a transmitting antenna, a receiving antenna (often the same antenna is used for both transmitting and receiving), and a receiver and processor that ascertain the properties of the objects.
Therefore, To use radar, a weather tower sends out radio waves and then detects the waves that are reflected back to the tower There is a large amount of rain or snow in the area.

Jacky leaves the office at 4:15 PM. If
she reaches her house at 4:55 PM
when her house is 25 km away from
her office, approximately, how fast did
she drive?
Given:
Jacky leaves the office at 4:15 PM and she reaches her house at 4:55 PM.
Distance between office and her house = 25 km
To find:
The driving speed of Jacky.
Solution:
The difference between 4:15 PM and 4:55 PM is 40 minutes.
60 minute = 1 hour
1 minute = [tex]\dfrac{1}{60}[/tex] hour
40 minute = [tex]\dfrac{40}{60}[/tex] hour
= [tex]\dfrac{2}{3}[/tex] hour
We know that,
[tex]Speed=\dfrac{Distance}{Time}[/tex]
[tex]Speed=\dfrac{25}{\dfrac{2}{3}}[/tex]
[tex]Speed=\dfrac{3\times 25}{2}[/tex]
[tex]Speed=\dfrac{75}{2}[/tex]
[tex]Speed=37.5[/tex]
Therefore, the driving speed of Jacky is 37.5 km per hour.

Analyze the given diagram of the carbon cycle below.
Part 1: Which process does arrow F represent?
Part 2: Explain how matter is conserved during the process.
Part 3: Justify why this process is a recycling of carbon in the carbon cycle.
Answer:
F means oxygen from plant goes into the atmosphere.
Explanation:
2. matter is conserved in this process because plants take carbon dioxide from the atmosphere for photosynthesis then produces oxygen into the atmosphere, animals then feed on plants and later the animal's faecal matter is released into the soil and even when animals die, microorganisms in the soil break I down into absorbable form for plants use. which makes matter conserved.
3. mater is in a circular state from atmosphere to plants to animals to soil then absorbed by plants to restart the process again.
