Answer:
CuCl2 + H2S -> CuS + 2HCl
Explanation:
in the reactants the 2 in 2HCl multiplies to give you 2 Hydrogens and 2 Chlorides.
From left to right, follow the dots in line 1 with your finger. Count a steady beat out loud, and time your motion so your finger crosses a dot at the end of each beat. Don’t pause at the dots, and move as smoothly as you can. A good way to count is to say or think “1 Mississippi, 2 Mississippi,” and so on. Is your finger moving at a constant rate, or is the rate changing?
Answer:
A) The rate changes as i move my finger

explain why severe storms occur along front
Answer:
Violently rising air ahead of cold fronts often leads to powerful thunderstorms.
Explanation:
Answer:
Stormy weather as the warm air mass at the surface rises above the cool air mass,
Explanation:
vigorous rising motion is often produced, leading to the development of showers and occasionally severe thunderstorms.
Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms. ... These clouds form in the warm air that is high above the cool air. As the front passes over an area, the clouds become lower, and rain is likely.

A person walks 20 meters to the east and then 20 meters to the west. Find distance and displacement.
Which type of rock is loosely held together?
Graphite
Igneous
Metamorphic
Sedimentary
Answer:
Sedimentary!
Why??? Well!! Sediment is loose material and sedimentary rock holds together when you pick it up.
An object is initially located 20 meters to the right of the origin and walks back (that is, to the left) being located 30 meters with respect to the origin. Calculate distance and offset.
Answer:
Is it 50 meters if I'm wrong I'm sorry

I’m not the greatest at physics my strong points are writing but I really need to do this to pass science this trimester pls help!
There’s more questions but I can only add 5 questions so- haha ima put the rest in different questions!
need help fast!!!! plz
What is the process that occurs when snow heats up and turns into a liquid?
Evaporation
Melting
Freezing
Condensation
What is the equation for the mechanical advantage of a lever?
MA = length of effort arm / length of resistance arm
MA = length of resistance arm/length of the effort arm
MA = length of effort arm + length of resistance arm
MA = length of effort arm * length of resistance arm
I think it is the second one, is that correct? HELP!
Answer:
MA = length of resistance arm/length of the effort arm
MA = length of resistance arm/length of the effort arm
PLS HELP!!! Which are examples of a phase change? (Select all that apply.)
evaporating water
cutting wood
frying eggs
melting butter
Answer:
evaporating water, frying eggs, melting butter.
Explanation:
Answer:
Evaporating water
Melting butter.
Explanation:
For a phase change to occur, heat energy needs to be released or absorb, and the process can be reversible. A phase change can cause physical changes but no new substance is formed.
These are examples of phases changes:
Melting: solid to a liquid (Melting butter)Freezing: liquid to a solidVaporization/Evaporation: liquid to a gas (Evaporating water)Condensation: gas to a liquidSublimation: solid to a gasDeposition: gas to a solid→Frying eggs in a chemical change (not reversible, a new substance is formed).
→Cutting wood is a physical change.
(*) My little brother (5th grade) just took the test and -evaporating water & melting butter- were the right answers.
(**) Hope this helps others who are looking for the answer of this question :)
Where do earthquakes occur?
Answer:
Over 80 per cent of large earthquakes occur around the edges of the Pacific Ocean, an area known as the 'Ring of Fire'; this where the Pacific plate is being subducted beneath the surrounding plates. The Ring of Fire is the most seismically and volcanically active zone in the world.
Explanation:
hope this helps
I hope this question is now on the correct level. I don’t understand the chart, 14, and 16.
HELPPPPP ASAP PLZZZZZZ WILL MARK BLAINIEST!
Use your model to explain how one of these metamorphic rocks: gneiss, marble, or quartzite could become igneous or sedimentary rock and how that rock could become a third type of rock.
my model: I could add to my model if it is needed in the answer.
Finally, repeat the procedure for line 3. Count a steady beat, and time the motion of your finger so it crosses a dot at the end of each beat. Is your finger moving at a constant rate or a changing rate along line 3?
Answer:
it is changing rate along line 3

If the earth were less massive, what effect might that have on the gravitational attraction between the earth and the people on its surface? Support your answer with evidence from the text.
Answer:
if the earths mass were to spontaneously decrease, and the mass of its inhabitants were to stay the same, then the gravitational attraction between the 2 would be less.
Explanation:
cant provide evidence because you didn't include any text.
If the earth would have been less massive the gravitational attraction of the planet would change.
The strength of the gravitational force depended on the mass and distance. The gravitational attraction of the elements on the earth's surface would also be less and would tend to have no balance.The greater is mass the greater is gravity.
