Fill in the coefficients that will balance the following reaction:
(Note: Use 1 as coefficient where appropriate.)
CH4 +
O2 →
CO2 +
H2O
Answer:
CH4 + 2 O2 → CO2 + 2 H2O
Explanation:
There are one mole of O2 on the left side and on the right side there are three moles of O2. And to fix it you would need to make it two moles of O2 to have four molecules of O2 on the left side. Then you would make two moles of H2O to have a total of four moles of O2 on the right. Therefore, CH4 + 2 O2 → CO2 + 2 H2O is the answer.

there are many mistakes : electrons are revolving in shell or orbits around the nucleus.
first shell always has two electron
after first shell , all shells contains eight electrons
electron have negative charge
proton have positive charge
nucleus have no charge
atom is neutral becoz the + charge of proton. and - charge of electron cancel each other's effect and atom is stable and neutral

numerical Through the two ends of glass-tube of lenght 2 meters, hydrogen chloride and ammonia gases are allowed to enter.At what distance ammonium chloride will first appear?
Answer:
81cm is the answer.
Explanation:
Let X be the length from the HCl end, and therefore, (2-x) from the other end.
For X length, rate of diffusion is :
dx/dt=P A/(Square root of 36.5T
d(2−x)/dt=PA/(square root of 17 T
Dividing both we get;
X/(2−x)= square root of 36.5/17
X=2/2.466=0.81 or81cm
Why is it important to classify living organisms? The DNA of organisms may be more easily analyzed. Organisms may survive longer if they are classified. Scientists may study and discuss organisms more easily. Classifying is needed before scientists may make observations.
Answer:
All living things are organized into groups by scientists as they are identified. Living things organized into particular groups have common characteristics. Overall, the reason scientists classify living things is to understand the relationships between different organisms

Uranium-235 undergoes the following fission process after
absorbing a neutron:
235 U +in+Kr + 14 Ba + xon
What is the value of x?
x =
Your answer should be a number.
The value of x = 3
Further explanationFusion and fission reactions are reactions involving atomic nucleus reactions
Fission reaction is a nucleation division reaction by firing a particle usually neutron so that it gets smaller particles of atomic nuclei.
Fission of Uranium-235
[tex]\tt ^1_0n+^{235}_{92}U\rightarrow ^{141}_{56}Ba+^{92}_{36}Kr+3^1_0n[/tex]
In this reaction, the sum of the mass number and atomic number of the elements involved in the reaction will be equal
atomic number left : 0+92=92
atomic number right : 56+36=92
mass number left : 1+235=236
mass number right : 141+92+3=236
The value of x in the fission process of uranium has been 3.
Fission reaction has been the nuclear reaction resulting in the breaking of the element into smaller substituents. The fission of uranium has been:
n + U [tex]\rightarrow[/tex] Ba + Kr + n
In the given fission reaction, the mass number of the atoms on the right and left of the reaction has to be equal. The mass number has been;
235 + 1 = 141 + 92 + x
236 = 233 + x
x = 236 -233
x = 3
The value of x in the fission process of uranium has been 3.

Group 17 is called the halogen family, and the group to its right is called the noble gases. How are these elements alike and how are they different?
Explanation:
The halogen family and noble gases are similar in just one particular way, they are groups of non-metals. All members of these two groups are categorized as non-metals.
Here are some of the differences between them;
Halogens have 7 electrons in their outermost shell whereas noble gases have 8 electrons in theirs. Halogens are highly reactive elements, noble gases are non-reactive. Halogens are made up of electronegative elements where as noble gases are neither electropositive nor electronegative.Identify ALL the possible mol ratio from
this balanced equation:
Answer:
[tex]\frac{1 mole of N_{2} }{3 moles of H_{2} }[/tex]
Explanation:
The equation of the reaction:
Nitrogen gas N₂ reacts with Hydrogen as H₂ to produce ammonia NH₃;
N₂ + H₂ → NH₃
The balanced equation is ;
N₂ + 3H₂ → 2NH₃
The mole ratio is the ratio of the coefficients of the combining reactants;
1 mole of N₂ combines with 3 mole of H₂;
So;
[tex]\frac{1 mole of N_{2} }{3 moles of H_{2} }[/tex]
As a 7 inch candle burns down, its height decreases 1/2 inch each hour. How many hours does it take for the candle to burn completely?
Answer:
14
Explanation:
Answer:
As a 7-inch candle burns down, its height decreases 1/2 inch each hour. How many hours does it take for the candle to burn completely?
Explanation:
It would be 14 because the candle is 7 inches and it loses 1/2 inch each hour.

What is the independent variable based on the hypothesis below?
"If acid rain is in water, then fish populations will increase"
Answer:
Acid rain
Explanation:
The independent variable in the hypothesis statement is the acid rain. An independent variable is usually the cause in an experiment.
This variable give rises to the effects observed as the dependent variable.
In the presence of the acid rain, the fish population will increase.
The dependent variable is the fish population or number of fishes.
The independent variable is the acid rain as it is the cause of the effect observed on the fish population.

What is the coefficient for titanium tetrachloride when the equation below is balanced?
TiCl4+H2O=TiO2+HCl
TiCl₄+2H₂O⇔TiO₂+4HCl
The coefficient for titanium tetrachloride = 1
Further explanationEqualization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:
1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.
2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product
3. Select the coefficient of the substance with the most complex chemical formula equal to 1
Reaction
TiCl₄+H₂O⇔TiO₂+HCl
give coefficient
TiCl₄+aH₂O⇔bTiO₂+cHCl
Ti, left=1, right=b⇒b=1
Cl, left=4, right=c⇒c=4
H, left=2a, right=c⇒2a=c⇒2a=4⇒a=2
O, left=a, right=2b⇒a=2b⇒2=2.1⇒match

Answer:
Newton's First Law...
Explanation:
The only force that acts on the car is the sudden deceleration from v to 0 velocity in a brief period of time, due to the collision with another object. However, when viewing the total system, the collision in the situation with two cars releases twice as much energy as the collision with a wall

What type of reaction takes place when potassium iodide reacts with chlorine gas?
a
Double Replacement
b
Decomposition
c
Synthesis
d
Single Replacement
Answer:
The correct answer is - d. single replacement or displacement.
Explanation:
The displacement or replacement reaction is the reaction in which the less reactive molecule or element is replaced by the more reactive element or molecule in the reaction. If there is only one replacement occurs its termed as a replacement or single replacement reaction.
In this case, if chlorine gas passes through the water solution of KI (potassium iodide), solid iodine and KCl are produced by the displacement or replacement reaction. Here iodine is less reactive so replaced by the more reactive chlorine.
2KI(aq)+Cl2 (g)→2KCl(aq)+I2 (s)

Why do we dream? Help me Please;)
Answer:
Explanation:
we dream because when our bodies are taking memories into long term, the memories from that day or the day before collide and make dreams. that is why they resemble things that have happened to us.
Answer:
One widely held theory about the purpose of dreams is that they help you store important memories and things you've learned, get rid of unimportant memories, and sort through complicated thoughts and feelings. Research shows that sleep helps store memories.
The brain is so active when we dream that it is virtually indistinguishable from a brain in the waking state. Even so, the chemistry of it is entirely rewired when we sleep. Many scientists attribute this to the reason dreams are so strange and bizarre.
