Answer:
The energy an object has due to its motion is called kinetic energy. Factors Affecting Kinetic Energy: the kinetic energy of an object depends on both its speed and its mass. The faster an object moves, the more kinetic energy it has.

Highlight the examples of radiation in the passage
below.
A chemist working in the laboratory is
investigating the thermal energy of H2O in a
solid, liquid, and gas state. First, she places
ice in a pan on a burner and heats it. She
records the temperature at which the solid ice
melts. Next she takes the liquid water and
heats it in a microwave. The liquid begins to
bubble and evaporate into a gas. She records
the temperature at which the liquid water
turned into a gas.
Answer:
Heating of the liquid water in a microwave.
Explanation:
Radiation is a form of heat transfer process that does not require a material medium rather it travels through space or vacuum in the form of electromagnetic waves or radiation. Heat transfer by radiation occurs in the form of microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. Some common examples of heat transfer by radiation is the warming of the Earth by the Sun, the warmth one experiences while sitting by the campfire, or the heating up of foods in a microwave.
Black bodies or surfaces are good absorbers as well as emitters of radiation. On the other shiny or white surfaces are poor radiators of heat.
From the above discussion on radiation, it can be seen that when the chemist takes the liquid and heats it in a microwave, the heat absorbed by the liquid to change to gaseous state is transferred through radiation.

Find the amount of atoms from 128 grams of NaCl?
Answer:
13.25 ×10²³ atoms
Explanation:
Given data:
Mass of NaCl = 128 g
Number of atoms = ?
Solution:
First of all we will calculate the number of moles of NaCl.
Number of moles = mass/molar mass
Number of moles = 128 g/ 58.4 g/mol
Number of moles = 2.2 mol
Number of atoms:
1 mole of any substance contain 6.022×10²³ atoms.
2.2 mol × 6.022×10²³ atoms / 1mol
13.25 ×10²³ atoms

Cyanobacteria use the process of
to produce energy, and oxygen is given off as a waste product.
Answer:
Photosynthesis utilizes water as an electron donor in cyanobacteria in general and creates oxygen as a by-product, although some can even use hydrogen sulfide, a process that occurs among other photosynthetic bacteria, such as purple sulfur bacteria. Carbon dioxide is reduced via the Calvin cycle to form carbohydrates.
N2 + 3H2 → 2NH3
How many moles of NH3 could you make with 4.2021 g of N2?
I need this like rn pls .
Moles of NH3 = 0.3 moles
Further explanationGivenN2 + 3H2 → 2NH3
4.2021 g of N2
Required
moles of NH3
Solution
mol N2 :
= 4.2021 g : 28 g/mol
= 0.15
From the equation, mol NH3 :
= 2/1 x mol N2
= 2/1 x 0.15
= 0.3 moles
Describe what causes the airbag to inflate on the particle level
Answer:
The chemical at the heart of the air bag reaction is called sodium azide, or NaN3. CRASHES trip sensors in cars that send an electric signal to an ignitor. The heat generated causes sodium azide to decompose into sodium metal and nitrogen gas, which inflates the car's air bags
Explanation:
Boron carbonate decomposes into boron oxide and carbon dioxide, how many moles of carbon dioxide are produced when 5.0 mol of boron carbonate decomposes completely?
Using the balanced chemical equation:
4NH3 + 302 --> 2N2 + 6H20
Determine the amount of grams of N2 is produced If 4.03 moles of NH3 react?
Taking into account the reaction stoichiometry, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.
Reaction stoichiometryIn first place, the balanced reaction is:
4 NH₃ + 3 O₂ → 2 N₂+ 6 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
NH₃: 4 molesO₂: 3 molesN₂: 2 molesH₂O: 6 molesThe molar mass of the compounds is:
NH₃: 17 g/moleO₂: 32 g/moleN₂: 28 g/moleH₂O: 18 g/moleThen, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
NH₃: 4 moles ×17 g/mole= 68 gramsO₂: 3 moles ×32 g/mole= 96 gramsN₂: 2 moles ×28 g/mole= 56 gramsH₂O: 6 moles ×18 g/mole= 108 gramsMass of N₂ formedThe following rule of three can be applied: if by reaction stoichiometry 4 moles of NH₃ form 56 grams of N₂, 4.03 moles of NH₃ form how much mass of N₂?
[tex]mass of N_{2} =\frac{4.03 moles NH_{3} x56 grams of N_{2} }{4 moles NH_{3}}[/tex]
mass of N₂= 56.42 grams
Then, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.
