4
Explanation:
Answer:
8 atoms
Explanation:
There are two sets of NH4 ( 2NH4) and the subscript means there are 4 hydrogen atoms in every set. if you distribute the 2, 2*4=8
2(NH4) = N2H8

Which is the correct formula for acceleration? I got acceleration = change in speed / time
To calculate the acceleration of an automobile, you must first subtract the final speed from the initial speed. True or false. I got true but i also kinda thimk false
Answer:
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
Explanation:
Answer:
∞∞∞∞∞∞║Δ║Hello Friend║Δ║∞∞∞∞∞∞Your answer should be:
1. Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction—or change both.
If you’re not changing your speed and you’re not changing your direction, then you simply cannot be accelerating—no matter how fast you’re going. So, a jet moving with a constant velocity at 800 miles per hour along a straight line has zero acceleration, even though the jet is moving really fast, since the velocity isn’t changing. When the jet lands and quickly comes to a stop, it will have acceleration since it’s slowing down.
2. True (Because if you subtract the final speed to the initial speed, you can see how much acceleration you put on or took off.

Basically, you have to decide if these are reactants or products.
This passage describes a chemical reaction. Read the passage. Then, follow the instructions below.
Buttermilk is a dairy product that contains lactic acid (C3H6O3). The lactic acid makes buttermilk a useful ingredient in pancakes. When buttermilk is added to pancake batter, lactic acid combines with baking soda (NaHCO3) to make carbon dioxide gas (CO2). This gas forms bubbles in the batter, causing the pancakes to rise and become fluffy as they cook.

What are the forms of light energy in solar radiation and the colors in white light?
(it has to be atleast 2 sentences)
Answer:
Light is a kind of energy called electromagnetic radiation. There are many different forms of electromagnetic radiation, such as radio waves, microwaves, ultraviolet rays, and X-rays. Each form is characterized by a different wavelength. For example, radio waves can be several miles long, while gamma rays are smaller than atoms. The light that we see — visible light — falls somewhere in the middle of this "electromagnetic spectrum.
What does the diagram show?
- one battery, two light bulbs, and three resistors
- one battery, two switches, and three light bulbs
- one switch, one resistor, and three light bulbs
- one switch, one light bulb, and three batteries
The diagram show one battery, two switches, and three light bulbs. Therefore, the correct option is option B.
What is electric circuit?Electric circuit: a way for current to travel. A battery or generator, a device that provides energy to a charged particles that make up the current, a device that uses current, such as a lamp, an electric motor, or a computer, as well as the connecting wires and transmission lines make up an electric circuit.
Ohm's law and Kirchhoff's rules are two fundamental laws that quantitatively define how electric circuits function. Many categories are used to categorise electric circuits. One-way current only flows through a direct-current circuit. As in most residential circuits, an alternating-current circuit transports current that pulses back and forth repeatedly every second. The diagram show one battery, two switches, and three light bulbs.
Therefore, the correct option is option B.

Which agent most changes the earth's surface? O A. moving ice B. wave action O C. running water O D. tide action E. cloud movement
The correct answers are B. Clouds and D. Storm systems.
Explanation:
"Convection currents are the result of a physical-chemical process in which chemicals are heated and this decreases their density, causing their elevation. At the same time, the elements in the top sink because of lost temperature and increase in density, creating a cycle. According to the above, the correct answers are B Clouds and D. Storm Systems. Clouds are the result of a cycle of water, in which the water on the earth in a liquid state evaporates due to the caloric energy from the sun, changing to a gas state and go up until becoming droplets again in a process called condensation forming cloud. Once the cloud is very heavy and lost its temperature, it precipitates to the earth due to the force of gravity, and then the cycle starts again. Secondly, storm systems are a kind of cloud, those clouds develop vertically thanks to the convection process, in this, the same process occurs but the clouds have an internal air stream that makes that the clouds grow up vertically producing storms, those clouds are known as Cumulonimbus and Cumulus congestus. So, the correct answers are B. Clouds and D.Storm systems."

The Earth moves in predictable patterns. One of these patterns causes
approximately 12 hours of daylight and 12 hours of darkness during a 24-hour
period in areas around the equator. This movement is referred to as -
A. a rotation
B. an equinox
C. a photoperiod
D. a revolution
The Earth moves in predictable patterns. One of these patterns causes approximately 12 hours of daylight and 12 hours of darkness during a 24-hour period in areas around the equator. This movement is referred to as rotation.
What is rotation?When a spherical, three-dimensional object rotates around an invisible line inside of its center, it is a relatively common type of rotation. This focal point is known as an axis. Basketballs in motion revolve around an axis. Axially rotating globes are used. The Earth itself has an axis of rotation.
The axis of the Earth is vertical, which means it moves up and down. (A rolling log, on the other hand, runs sideways and has a horizontal axis.) The North and South Poles are on opposite sides of the Earth's axis. The Earth moves in predictable patterns. One of these patterns causes approximately 12 hours of daylight and 12 hours of darkness during a 24-hour period in areas around the equator. This movement is referred to as rotation.
Therefore, the correct option is option A.

What is electromagnetic spectrum?The electromagnetic spectrum consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.
