Answer:
Same.
Explanation:
The temperature of each 400mL bucket is about the same as the temperature of the original bucket of paint.
This is because the temperature is an intrinsic property.This means that temperature is independent of the quantity of matter. Therefore, the temperature of paint inside the bucket is not dependent on the amount of paint present.
The level of CO2 in the blood is detected by chemoreceptors located in the aortic arch
and carotid arteries. These send impulses to either the cardioaccelerator or
cardioinhibitor center in the hypothalamus of the brain, which in turn sends an
impulse to the pacemaker of the heart to increase or decrease heart rate. Draw a
feedback diagram to illustrate what happens to restore homeostasis when blood CO2
rises.

Cynthia has 200kg of magnesium. Calculate how much MgCl2 she can make.
Mg + Cl2 = MgCl2
Answer:
784.4kg
Explanation:
Given parameters:
Mass of Mg = 200kg
Unknown:
Mass of MgCl₂ = ?
Solution:
The reaction equation is given as:
Mg + Cl₂ → MgCl₂
Find the number of moles of the given specie;
Number of moles of Mg = [tex]\frac{mass}{molar mass}[/tex] = [tex]\frac{200000}{24.3}[/tex] = 8230.5mole
So;
1 mole of Mg will produce 1 mole of MgCl₂
8230.5mole of Mg will produce 8230.5mole of MgCl₂
Mass of MgCl₂ = number of moles x molar mass
Molar mass of MgCl₂ = 24.3 + 2(35.5) = 95.3g/mol
Mass of MgCl₂ = 8230.5mole x 95.3g/mol = 784.4kg
A photocopier is making reduced copies of a photo that measures 25 centimeters in height. The height of the first copy is 80% of the height of the original. Another copy is made using the first copy, and the height of this copy is 85% of the height of the first copy. Answer parts a and b.
Answer:The height of First Copy is 20 cm.
Step-by-step explanation:
Given:
Original Height = 25 cm
First copy is reduce to 80% of Original height.
Therefore to find the height of first copy can be find out by multiplying 80 with original height and then dividing by 100.
∴ Height of First Copy =
Hence Height of first copy is 20 cm
Now Another copy is reduce to 85% of First Copy.
Therefore to find the height of another copy can be find out by multiplying 85 with first copy height and then dividing by 100.
∴ Height of Another Copy =
Hence Height of Another copy is 17 cm

How many seconds in 4.3 years?
In the given question, 136293840 seconds are present in 4.3 years.
A second is a unit of time that is equal to 1/60th of a minute and is used to measure short periods of time.
To convert 4.3 years to seconds, we can use the following conversion factors:
1 year = 365.25 days (accounting for leap years)
1 day = 24 hours
1 hour = 60 minutes
1 minute = 60 seconds
So, we can start by multiplying the number of years by the number of days per year:
4.3 years [tex]\times[/tex] 365.25 days/year = 1577.475 days
Next, we can multiply the number of days by the number of hours per day:
1577.475 days [tex]\times[/tex] 24 hours/day = 37859.4 hours
Then, we can multiply the number of hours by the number of minutes per hour:
37859.4 hours [tex]\times[/tex] 60 minutes/hour = 2271564 minutes
Finally, we can multiply the number of minutes by the number of seconds per minute to get the total number of seconds:
2271564 minutes [tex]\times[/tex] 60 seconds/minute = 136293840 seconds
Therefore, in 4.3 years there are approximately 136293840 seconds.

In two or more complete sentences describe all of the van der Waals forces that exist between molecules of water.
Answer:
Van der Waals forces is defined as the force that include attraction and repulsions between atoms or molecules, and also involve intermolecular forces
Vander Waals force formed between the similar molecules and not different molecules, that means Van der Waals force exist between two water molecules and not between hydrogen and oxygen of one molecule. Hydrogen and oxygen are connected with covalent bonds.

Explanation:
Water, H2O, frequently forms Hydrogen Bonds with other non metal atoms.
Why does water do this?
A: the Oxygen has a partial negative charge which attracts atoms and molecules that have a position or partial positive charge
B: The Hydrogen has a partial negative charge which attracts atoms and molecules that have a positive or partial positive charge
C: Because Oxygen is extremely electronegative it attracts atoms and molecules with a negative or partial negative charge
D: Because Hydrogen has a very low electronegative rating it attracts atoms and molecules with a positive or partial positive charge
Answer:
Opposite charges attract one another. The slight positive charges on the hydrogen atoms in a water molecule attract the slight negative charges on the oxygen atoms of other water molecules. This tiny force of attraction is called a hydrogen bond.
Considering the definition of hydrogen bond, the correct answer is option A: he Oxygen has a partial negative charge which attracts atoms and molecules that have a position or partial positive charge.
In hydrogen bonds, a molecule that presents hydrogen interacts with another that presents an atom with high electronegativity, such as oxygen, fluorine or nitrogen (O, F, N). In this way, between the hydrogen, which has a low electronegativity and the electronegative atom, an interaction is established, due to their opposite charges.
On the other hand, electronegativity is the ability of an atom to attract shared electrons in a covalent bond.
In the case of water, because oxygen is more electronegative than hydrogen, electrons, which have a negative charge, are more likely to be closer to the oxygen atom than to the hydrogen atom, which causes each hydrogen atom to have a positive charge is called a positive partial charge, and that of oxygen, a negative charge, since it has the electrons closer together.
In summary, the correct answer is option A: he Oxygen has a partial negative charge which attracts atoms and molecules that have a position or partial positive charge.

A drop in water temperature is observed when 0.848 g of ammonium nitrate is added. The enthalpy change for this reaction is +0.117 kJ. Calculate the Δ Hrxn, in kJ/mol, for this reaction.
The Δ Hrxn, in kJ/mol, for this reaction= 11.04 kJ/mol
Further explanationGiven
0.848 g ammonium nitrate
The enthalpy change : +0.117 kJ
Required
Δ Hrxn, in kJ/mol
Solution
Delta H reaction (ΔH) is the amount of heat change between the system and its environment
The value of ° H ° can be calculated from the change in enthalpy of standard formation:
∆H ° rxn = ∑n ∆Hf ° (product) - ∑n ∆Hf ° (reactants)
mass of NH4NO3 = 0.848 g
mol of NH4NO3(MW = 80 g/mol)
mol = 0.848 : 80
mol = 0.0106
The Δ Hrxn :
= 0.117 kJ : 0.0106 mol
= 11.04 kJ/mol
Daffodil is ordering office supplies for her company. When she tries to order pencils, she finds that pencils are sold by the gross, which is equal to 144 pencils. Daffodil checks how many pencils her company uses in a year, and decides to order 5 gross of pencils. How many pencils will she receive? Remember to include units (full word, plural, WATCH YOUR SPELLING) as they are worth half of this question.
Answer:
720 pencils
Explanation:
The parameter given are;
The unit quantity by which the pencils are sold = 1 gross
The number of pencils Daffodil orders = 5 gross of pencils
One gross is a quantity equal to twelve dozens
Therefore, we can write;
1 gross = 12 × 12 = 144
From which we have;
5 gross = 5 × 144 = 720
Which gives;
For the 5 gross of pencils Daffodil orders, she receives 720 pencils
If a sample contains 22 moles of CsPO4, what is the mass of that sample?
Answer:
Mass = 5013.36 g
Explanation:
Given data:
Number of moles of CsPO₄ = 22 mol
Mass of sample = ?
Solution:
Formula:
Mass = number of moles × molar mass
Molar mass of CsPO₄ = 132.91×1 + 30.97×1 +16×4 = 227.88 g/mol
by putting values,
Mass = 22 mol × 227.88 g/mol
Mass = 5013.36 g
