In the chemical reaction CH4 + 2O2 → CO2 + 2H2O, there are reactants on the left of the equation and products on the right. If you count the atoms in the reactants, there are
a. 4 carbon atoms, 4 hydrogen atoms, and 2 oxygen atoms
b. 1 carbon atom, 4 hydrogen atoms, and 2 oxygen atoms
c. 1 carbon atom, 4 hydrogen atoms, and 4 oxygen atoms
d. 4 carbon atoms, 4 hydrogen atoms, and 4 oxygen atoms
Answer:
the answer is A. 4 carbon atoms, 4 hydrogen atoms, and 2 oxygen atoms
The number of atoms of each molecule of the reactants is required.
The correct option is c. 1 carbon atom, 4 hydrogen atoms, and 4 oxygen atoms
The given reaction is
[tex]CH_4+2O_2\rightarrow CO_2+2H_2O[/tex]
For carbon atoms
The only carbon atom is present in [tex]CH_4[/tex]
So, 1 carbon atom
The hydrogen atoms are also present is [tex]CH_4[/tex]
There are 4 hydrogen atoms.
The oxygen atoms present is [tex]2\times 2=4[/tex]
So, the number of atoms present in the reactants are c. 1 carbon atom, 4 hydrogen atoms, and 4 oxygen atoms

A 31 kg object is experiencing a net force of 25 N while traveling in a circle of radius 25m. What is its velocity?
Answer:
4.5m/s
Explanation:
Given parameters:
Mass of object = 31kg
Net force = 25N
radius = 25m
Unknown:
Velocity = ?
Solution:
To solve this problem, we must understand that the net force here is a centripetal force.
F = [tex]\frac{mv^{2} }{r}[/tex]
F is the centripetal force
m is the mass
v is the velocity
m is the mass
25 = [tex]\frac{31 x v^{2} }{25}[/tex]
31v² = 625
v² = 20.2
v = 4.5m/s

A car of mass 1000kg is moving at 10m/s when it hits a wall. The force of the car on the wall is 400 N. Calculate the stopping time
Answer:
25s
Explanation:
Given parameters:
Mass = 1000kg
Velocity = 10m/s
Force = 400N
Unknown:
Stopping time = ?
Solution:
To find the stopping time, we use Newton's second law of motion:
Ft = mv
F is the force
t is the stopping time
m is the mass
v is the velocity
400 x t = 1000 x 10
t = 25s
How long will it take for a 1.5A current to coat evenly a layer of copper 0.1mm thick on both sides of a 12cm x 12cm copper plate [e.C.E of copper= 0.00033g/C , density of copper 9g/cm
Answer:
Explanation:
First of all we shall calculate mass of copper to be calculated from the formula below.
mass = volume x density
volume = total surface area x thickness of layer
= 12 x 12 x 2 x .01 cm³
= 2.88 cm³
mass = 2.88 x 9 = 25.92 g .
Let time required be t s . .
charge flowing in time t = 1.5 t coulomb.
Given ,
1 coulomb deposits .00033 g of copper
1.5 t deposits .00033 x 1.5 t g of copper
So ,
.00033 x 1.5 t = 25.92
t = 52364 s
= 14.54 hours.

What happens when light runs into object
Explanation:
It depends on the object, actually. If the object is transparent or somewhat clear, the the light will end up refracting, or bending, through those clear objects. It can also bounce off objects, too. But, with some objects, the light can be blocked, or absorbed.
Answer:
See down below
Explanation:
When light hits glass or any other transparent material, it pass though. Some light is reflected off the object whereas the rest passes through and is refracted. As light passes through air and into another clear material it changes speed, and light is both reflected and refracted by the glass.When the light runs into a sold object, it prevents from going through it.
Lightning flashes and you hear a thunder clap for seconds later. the velocity of sound is 340 m/s. how far away did lightning strike ?
Answer:
For metric-system conversions, follow this method: Sound travels at about 340 m/s, so multiply the number of seconds you counted by 340, and you'll know how many meters away lightning struck. A three-second count, then, would place the lightning strike about 1,020 m away, or roughly 1 km.
Explanation:
hope it hep and if it doesnt sorry
The distance struck by the lighting flashes is 680 m.
The given parameters;
time taken to hear the thunder clap, t = 4 svelocity of sound, v = 340 m/sThe distance struck by the lighting is calculated by applying the principle of echo as follows;
[tex]v = \frac{2d}{t} \\\\2d = vt\\\\d = \frac{vt}{2} \\\\d = \frac{340 \times 4}{2} \\\\d = 680 \ m[/tex]
Thus, the distance struck by the lighting flashes is 680 m.

Answer:
C. amount of charge on the source charge.
Explanation:
Electric field lines can be defined as a graphical representation of the vector field or electric field.
Basically, it was first introduced by Michael Faraday and it is typically a curve drawn to the tangent of a point is in the direction of the net field acting on each point.
The number, or density, of field lines on a source charge indicate the amount of charge on the source charge. Therefore, the density of field lines on a source charge is directly proportional to quantity of charge on the source.
