As a chemist for an agricultural products company, you have just developed a new herbicide,"Herbigon," that you think has the potential to kill weeds effectively. A sparingly soluble salt, Herbigon is dissolved in 1 M acetic acid for technical reasons having to do with its production. You have determined that the solubility product Ksp of Herbigon is 9.00×10−6.
Although the formula of this new chemical is a trade secret, it can be revealed that the formula for Herbigon is X-acetate (XCH3COO, where "X" represents the top-secret cation of the salt). It is this cation that kills weeds. Since it is critical to have Herbigon dissolved (it won't kill weeds as a suspension), you are working on adjusting the pH so Herbigon will be soluble at the concentration needed to kill weeds. What pH must the solution have to yield a solution in which the concentration of X+ is 1.50×10−3 M ? The pKa of acetic acid is 4.76.

how many grams of carbon tetrachloride can be produced from reacting 709.0 grams of chlorine (CI2) with excess methane?
How is a molecule different
from an element?
A. An element is made of more than one
type of atom.
B. A molecule has properties different
from the elements making up the
molecule.
C. An element shares electrons and a
molecule does not.
Answer:
A
Explanation:
Molecule is a substance with two or more atoms bonded together such as the oxygen humans breathe (O2). Elements are pure substances made up of all the same atoms such as gold (Au), hydrogen (H), and oxygen (O). Elements all have the same number of protons in their nuclei and can't be broken down.

A sample of gas has a volume of 12.0L and a pressure of 2.00 atm. If the pressure of gas is increased to 6.00 atm, what is the new volume of the gas?
A. 2L
B. 4L
C. 16 L
D. 8L
Answer:
B; 4 L
Explanation:
From the Boyle’s law of gases, the volume occupied by a given mass of gas is inversely proportional to the pressure exerted by the gas
Mathematically, we have this as;
PV = K
Given;
P1 = 2 atm
V1 = 12 l
P2 = 6 atm
V2 = ?
We have that;
P1V1 = P2V2
2 * 12 = 6 * V2
V2 = (2 * 12)/6
V2 = 24/6
V2 = 4 L

Answer:
I believe that it is the 2nd option.
Explanation:
My reasonings are because C4H10O has 7 isomers. In which 4 are alcohol and the other 3 are ether.
The first option is ethers, specifically ethoxyethane.
The third option is ethers, specifically 1-methoxypropane.
The fourth option is an alcohol, specifically 1- butanol.
Therefore, leads us to the 2nd option that it is NOT an isomer of C4H10O

An insecticide kills many insects, but a few survive. Because of natural selection, which of the following is most likely to happen
1- Eventually the survivors will become resistant to insecticide
2- the survivors will reproduce, and the offspring will be resistant to the insecticide
3- the survivors will reproduce, but the offspring will be killed by another application of the insecticide
4- the survivors will continue to survive for many years beyond their normal lifespan
Answer:
2
Explanation:
the ones that survived are the ones that had the favorable trait, so they'll be able to reproduce and their offsprings are likely to receive that trait as well.

PLEASE HELP What's the mass in grams of 0.442 moles of calcium bromide, CaBr2? The atomic
weight of Ca is 40.1 and the atomic weight of Br is 79.9.
A) 452.3 g
B) 53.04 g
C) 44.2 g
D) 88.4 g
Answer: Thus there are 88.4 g of calcium bromide.
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
Molar mass of = 40.1 (1)+ 2(79.9) = 199.9
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]
[tex]0.442=\frac{x}{199.9}[/tex]
[tex]x=88.4g[/tex]
Thus there are 88.4 g of calcium bromide.
A motor boat is traveling 10 m/s on a sunny calm day. The driver turns
off the engine. Apply Newton's first law to explain what happens to the
boat as it glides through the water. *
Answer:
If there is no resistance, current, wind, or friction on the boat, the boat would keep moving in the same direction at the same speed.
Explanation:
Newton's First Law of Motion suggests that if no external force acts upon an object, that object would continue moving in the same direction at the initial speed.
However, all objects near the surface of the earth (including the boat in this question) experience the effect of gravitational pull (an external force from the earth.) Because of these external forces, Newton's First Law of motion (when phrased in this way) would not apply to the boat.
It is frequently possible to use a more general version of this statement: if the net force on an object is zero, that object would continue moving in the same direction at the initial speed.
In other words, the object would move in the same direction at the initial speed as long as all the external forces on that object balance each other.
Assume that there is no resistance, current, wind, or friction on the boat. After the engine of the boat is turned off, the following would be the forces on this boat:
downward gravitational attraction from the earth, andupward buoyancy from the water, which counteracts the gravitational attraction on the boat.If the water is sufficiently calm, these two forces would balance one another. The external force on this boat would be zero. Hence, the boat would keep moving in the same direction at the same speed.

"What is the potential energy relative to the water surface of a diver at the top of a 26 m
high diving platform? Suppose she has a mass of 35 kilograms."
Answer:
PE = 8918 J
Explanation:
Formula for potential energy here is;
PE = mgh
Where;
m is mass
g is acceleration due to gravity
h is height
We are given;
m = 35 kg
h = 26 m
Thus;
PE = 35 × 9.8 × 26
PE = 8918 J

Dogs are derived from wolves. Today, dogs are very diverse, varying in size from very small to very large. What led to this variety
1 - selective breeding
2- cloning
3- Genetic Engineering
4- Natural Selection
Answer:
1
Explanation:
i think but yes
Dogs are derived from wolves. Dogs are very diverse, varying in size from very small to very large. The variety is because of selective breeding. Hence option 1 is correct.
What is selective breeding?Selective breeding is defined as the method by which people pick which male and female animals or plants would reproduce sexually and create offspring together in order to selectively acquire specific phenotypic features. The goal of selective breeding is to produce cattle with desirable features that are strongly heritable and can thus be passed down from generation to generation.
Despite the fact that all dogs are descended from wolves, people have significantly changed the appearance of dogs through the use of artificial selection. Dogs have been bred for various desirable traits for ages, resulting in a vast variety of canines, from the little Chihuahua to the enormous Great Dane.
Thus, dogs are derived from wolves. Dogs are very diverse, varying in size from very small to very large. The variety is because of selective breeding. Hence option 1 is correct.
