Which mathematical statement shows the formula for weight?
Answers
Answer
(:
Weight is basically a measure of theme force of gravity pulling down on an object. It depends on the object's mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object's weight in Newtons (N) and m is the object's mass in kilograms.

Which of the following lists the relative strengths of the fundamental forces from strongest to weakest?
A. Strong nuclear force weak nuclear force, gravitational force, electrostatic force
B. Gravitational force, strong nuclear force electrostatic force, weak nuclear force
C. Electrostatic force, gravitational force, weak nuclear force, strong nuclear force
D. Strong nuclear force, electrostatic force, weak nuclear force, gravitational force
Answers
Answer:
D. Strong nuclear force, electrostatic force, weak nuclear force, gravitational force
There are four fundamental or universal forces in nature. Without these forces, all matter in the world will fall apart. The relative strength of fundamental forces is Strong nuclear force, electrostatic force, weak nuclear force, gravitational force. Thus the correct option is D.
What are fundamental forces?The fundamental forces are also called the fundamental interactions. All the known forces of the nature can be collectively called the fundamental forces. The four important fundamental forces are gravitational, electrostatic, strong and weak nuclear forces.
The gravitational force is the weakest fundamental force. It is an attractive force which arises from the gravitational interaction. The attractive as well as the repulsive force caused by the electrically charged particles is defined as the electrostatic force.
The nuclear force is the strongest attractive force. The strong nuclear forces hold the nuclei of atoms together. The weak nuclear forces are responsible for the radioactive decay.
Thus the correct option is D.

What happens to the hydrogen ion (H+) concentration as an aqueous
solution becomes more acidic? *
A)decreases
B)increases
C)remains constant
D)cannot be determined
Answers
Answer:
Explanation:
It can be determined by measuring the Ph. D is incorrect.
C: is wrong because if you are making something acidic, you are increasing the H+
B: is the correct answer.
A: pH decreases. H+ increases which makes the Ph decrease. It is an oddity of the formula that makes this happen.
Explanation: As the level of hydroxide ions increases the more basic, or alkaline, the solution becomes. Thus, as the hydrogen ion concentration increases hydroxide ion concentration falls

Compound A reacts with alcoholic KOH to yield compound B which on ozonolyzises followed by the reaction with Zn/H2O gives methanal and propanal Compound A is
Answers
Answer:
1-chlorobutane
Explanation:
Given that :
-- The compound A is made to react with alcoholic KOH and produce compound B.
-- The compound B on Ozonolysis produces methanol as well as propanol
The compound A should be a haloalkanes as treatment of haloalkanes with the alcoholic KOH, it will give alkene.
[tex]$CH_3CH_2CH_2CH_2Cl+KOH( \text{alcohol}) \rightarrow CH_3CH_2CH=CH_2+KCl+H_2O$[/tex]
So, the compound B should be Butene
Now the ozonolysis of the compound B or butene will give methanol and propanal as shown :
[tex]$CH_3CH_2CH=CH_2 \rightarrow CH_2O+CH_3CH_2CHO$[/tex]
Therefore, the compound A is 1-chlorobutane.

how many moles of H2 are required to make 10 moles of water?
Answers
Explanation:
10 moles h20 is required
10 moles of H₂ are required to make 10 moles of H₂O.
What is Stoichiometry ?Stoichiometry is an important concept which helps us use the balanced chemical equation to measures the amount of reactants and products.
What is Balanced Chemical equation ?A balanced chemical equation is chemical equation that has equal number of atoms on both sides of arrow that is reactant and product.
First we have to write the Balanced chemical equation
2H₂ + O₂ → 2H₂O
To produce 2 moles of water, 2 moles of hydrogen are required to produce 10 moles of water.
So,
[tex]\frac{2\ \text{moles of}\ H_2}{2\ \text{moles of}\ H_2O}[/tex] × 10 moles of H₂O
= 10 moles of hydrogen are required.
Thus, from above conclusion we can say that 10 moles of H₂ are required to make 10 moles of H₂O.

Suppose I have enough ingredients to make 25 cookies, but when I go to bake them, I only get 5. What percent yield did I obtain?

Theor. yield from brown sugar

24 cookies
0.5
cup brown sugar
=
192 cookies
Finally, "we leave it as an exercise for the student" to calculate that
Theor. yield from margarine = 72 cookies
b. Identify the limiting reactant
The limiting reactant is the amount of chocolate chips because they can produce the smallest amount of cookies.
c. Determine the theoretical yield
The theoretical yield is 54 cookies, because that is all you can get from the chocolate chips provided.
The percent yield obtained on baking the cookies is 20 % and the theoretical yield is 25 cookies.
What is percent yield?Percent yield is defined as the ratio of actual yield to the theoretical yield multiplied by 100. If the actual and theoretical yield are same then the percent yield is 100%.If actual yield is less than the theoretical yield then the percent yield is less than 100%.Reason of this condition arising is the incompletion of reaction or loss of sample during recovery process.
In cases where percent yield is over 100% it indicates that more sample is recovered than the predicted amount.This condition arises when there are other simultaneous reactions taking place leading to the formation of product. It can also arise if there is incomplete removal of impurities from the sample .
As cookies obtained is 5 it is observed yield while 25 is theoretical yield so the percent yield, 5/25×100=20%.

If the pressure of a 2.00 L sample of gas is 50.0 kPa, what pressure does the gas exert if its volume is decreased to 20.0 mL?
Which equation should you use?
Answers
__________________________________________________________
Which equation should you use?
B. P₁V₁=P₂V₂
What is the new pressure?
✔ 5000 kPa
__________________________________________________________
Explanation:The problem gives initial volume (2.00 L), final volume (20.0 mL), and initial pressure (50.0 kPa). Then it asks to find the final pressure. Answer B has all these variables, with P₁=initial pressure, P₂=final pressure, V₁=initial volume, and V₂=final volume. Plug the given values into the equation and then solve for the unknown value, which is P₂, final pressure.
When plugging in the values, use consistent units. 2L=2000 mL, I chose to make the consistent unit in mL. You'll get the same answer if you choose to use L as the consistent unit.
[tex]2000*50=20*P2[/tex]
[tex]100000=20*P2[/tex]
Divide both sides by 20
[tex]100000/20=(20*P2)/20[/tex]
[tex]5000=P2[/tex]
