Answer:
2 chlorine atoms.
Explanation:
H₂ + Cl₂ → 2HCl
The Law of Conservation of Mass states that matter can neither be created nor destroyed in a chemical reaction.
If 2 molecules of Hydrogen and 2 molecules of Chlorine is present in the reactants, the same no. of atoms should also be present in the product.
∴ the no. of chlorine atoms in the product is 2.
How is relative age different from absolute age
Answer:
Relative age is the age of a rock layer.
Absolute age is the numeric age of a layer of rocks or fossils.
Explanation:
1. Which layers from North America are the same age as layers from Europe? Use the number or letter of the layer to identify it.
answer:
1 with A, 3 with D
explanation:
look at the images they have inside them and see ones matchThe Earth orbits the ....?
Answer:
the sun
Explanation:
Because the sun's gravity keeps the earth in it's position and also stop the earth from grifting away.

7. A pool player hits a cue ball with a speed of 10 m/s. If the mass of the ball is 0.16 kg, calculate the kinetic energy of the moving cue ball. (Show your work!)
Answer: 8 Joules
Explanation:
0.16/2=0.08
10²=100
0.08x100=8
The kinetic energy of the moving cue ball is 8 Joules

A gardener waters the plants in a garden using a garden hose during a drought. The gardener observes that most of the water given to the plants is wasted as runoff.
Which procedure would most likely reduce the amount of water lost as runoff?Replant each plant closer to one another.
Compress the soil to decrease the number of pores.
Cover the plants while they grow.
Break up the soil to increase the number of pores.
Answer:
Break up the soil to increase the number of pores should be your answer.
Explanation:
If you do that it will increase the amount of water in the plant.

which of the following statement is false?
A) The metal rods dipped in liquids to which cells are attached are called electrodes
B) The liquid which can conduct electricity by providing ions are electrolytes
C) Electroplating is the process of deposition of thin layer of desired metal on another substance
D) Positively charged electrode is called Cathode
Answer:
Positively charged electrode is called Cathode is false statement because it is called anode.
Will give brainly. How was the ancient idea of elements similar to what we now know about elements, and how was it different?
How is it possible that heat is transferring from the water in the tank to the water in the bag, even though the water in the tank doesn’t feel hot?
Answer:
animals unlike us adapt faster to heat/cool weather or water
Explanation: Let's use fish as an example because that's the main water pet, so when you get a new fish and you have to put it in the water for about let's say 15 minutes. It's so it can adapt to the water. Water for us needs to be hot enough for us to actually feel the heat so therefore animals can adapt not only faster to heat but to cool air/water a lot faster than we can. I don't know if this helps or makes sense but it's what I know and have seen :P

PLEASE HELP ME I BEG IM CONFUSED ON THIS ONLY QUESTION
Answer:
don't worry i'm not here to waste your points, i just have a question before i answer yours, what are the answer choices in the 'drop box' thing **where you pick the answer for the blanks**
Explanation:
Fredrick has two samples of pure water - sample X and sample Y. Sample X has a volume of 1 L and sample Y has a volume of 10 L. How do the boiling points of these two samples compare?
Group of answer choices
Sample X will boil at a lower temperature because it has less volume.
Sample Y will boil at a lower temperature because it has more volume.
Which ever sample receives heat first will have a lower boiling point.
Sample X and Y will boil at the same temperature.
Answer:
D. Sample X and Y will boil at the same temperature
Explanation:
The boiling point of a liquid is the temperature at which the vapor pressure equals the atmospheric pressure.
The boiling implies a phase change of water from liquid to vapor. This requires an input of energy in the form of heat. Since Y has a greater volume than X, Y will require a higher heat input. However, the boiling temperature will remain unchanged.

What are the steps to evaporate Copper sulfate crystals?
Answer:
copper sulfate is soluble in water its crystals dissolve in water to form copper sulfate solution. During evaporation, the water evaporates away leaving solid copper sulfate crystals behind. A solution is placed in an evaporating basin and heated with a Bunsen burner

In what phase of matter are most elements found?
Answer:
solid
Explanation:
solids
The 3 states of matter are either solid, liquid or gas. Most elements are solids, only 11 are gases and 2 are liquids.
Answer:
Gas, Liquid, Solid, or Synthetic depends on the element.
The main answer is solid
Explanation:
If you check here you will see the different elements and how they are found.
https://hobart.k12.in.us/ksms/PeriodicTable/naturalphase.htm#:~:text=Elements%20appear%20in%20their%20natural%20phase%20at%20room,krypton%2C%20neon%2C%20nitrogen%2C%20oxygen%2C%20radon%2C%20and%20xenon.%20Liquid.
You will see the grand majority of elements are solids.
