The rate law which is consistent withe the given chemical equation is rate=k[HBr][O₂] as the rate of reaction is dependent on concentration of both reactants that is HBr and oxygen.
What is chemical equation?Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

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
Answers
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
"What is the potential energy relative to the water surface of a diver at the top of a 26 m

Answers
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

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.

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
Answers
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.

1 - selective breeding
2- cloning
3- Genetic Engineering
4- Natural Selection
Answers
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.
