Temperature change for CaCO3 and HCI

Research questions:

  1. When the temperatures is digressed, or increased will the CaCO3 and HCI have a faster reaction?
  2. What happens when the reaction is happening?
  3. What happens when Caco3 and HCI meet each other?

Answers:

  1. When calcium mineral carbonate is heated up it first responds to the acid then after a while it becomes CaCO3 into calcium Hydroxide. Its created when ions bonds respond to the acid which makes electric charge so it heats up.
  2. When CaCO3 and HCI reacts, it sorts calcium chloride, water and skin tightening and. The reaction between both chemical substances requires two parts HCI and CaCO3. The effect is swift and enthusiastic at high concentrations. Large part credited high affinity of calcium ions for chloride ions
  3. Depending on the heat when Calcium chloride and Hydrochloric acid meet. Its charges start moving rapidly and a response will start to begin much faster. Both charges combine for a reaction to occur.

Background info:

The topic we have chosen is how temperature can change calcium carbonate and hydrochloric acid In various temperature like the standard temperature frigid and hot. (have no idea the knowledge behind it yet) A effect rate is the velocity how fast or poor the chemical effect proceeds It is said in terms of either amount the amount of unit volume of a product that is formed in a product of time. When you increase the temp, the particles speed up a lot however when you cool them down they get slower. when its heated up there is a faster response rate however when temperature is decreased, the reactions takes a whole lot longer cause the debris don't have a whole lot of energy has they would when warmed.

The collision theory is designed for ta chemical reaction to take place the reactant debris must collide jointly. Collison's with too little energy do not produce a reaction. It must have enough collisions to the vitality can make the contaminants react. (still surely got to add research)

The experiment the team is doing is screening what temp change does indeed to calcium carbonate and hydrochloric acid.

The way my research questions are going to assistance with the experiment is those people I have are what we should are manly looking for like. Just how long it takes for a a reaction to appear, will the heat change the original element. (forgot what my third was) they may be what we manly are inquisitive of and looking for. (using photos as diagrams if I can)

The chemical equation for calcium mineral carbonate and hydrochloric acid is CaCO3+HCI-CaCI2+CO2+H20

Aim:

The goal of the experiment is to exam if heat changes the speed of response for CaCO3 and HCI for frigid, hot and medium temp.

Hypothesis:

It is hypothesised that whenever CaCO3 complies with HCI it'll behave faster depending of the heat range. If the temp is hotter it has more energy cause its warm but if its colder they'll react much slower cause they have a frigid and also have less energy. It's like true to life people when chilly we don't want to do anything but hot you want to do a lot. When its medium temp it will have a medium response rate.

Equipment list:

  • Beakers (x3)
  • Thermometer
  • Hot plate
  • Ice cream bucket with ice
  • Measuring tube
  • Stop pieces (x3)
  • Calcium carbonate (3 grams)
  • Scales
  • Hydrochloric acid (144m total)
  • Safety glasses
  • Apron
  • Gloves

Method:

Throughout the experiment everyone was necessary to wear the following safety gear glasses, apron and gloves. For the test after the group put all the Protection equipment on the bench and on them. they moved on to grabbing the equipment then moving it slowly but surely and carefully to the work bench. Once everything was out on the bench ready then your group grabbed the Calcium carbonate(CaCO3) and hydrochloric acid (HCI) then assessed out the right amount for both scales were used for the CaCO3 and measuring pipe for the HCI. Following the HCI was poured into the beaker it was put in bucket packed with ice or over a hotplate then the calcium proceeded to go in. After five minutes of the hot plate or ice experienced the bucket check the temp also ensure you remember the effect rate time. Following the test is complete pack up and clean the gear then return all of it. Make sure you let the hotplates cool off before touching them.

Observations:

When the calcium mineral carbonate and hydrochloric acid was put together for the chilly test it brought about a reaction right away a whole lot of bumbles built up and punched to the very best almost exceeding the most notable of the beaker. All of the calcium was all gone except some very small parts for the normal temperature test drive it did the same put following the calcium began to dissolve.

Discussion:

In the test, there is some patterns that we found for the results such as chilly temp experienced a slow effect at the end but it was somewhat fast at start cause this round the beaker was still getting colder the temperatures remained the same. A effect for cold lasted for around 20-25 secs. For the medium test, it started at a temp of 24 for both in support of increased by one, a response started and concluded in about 10-15 moments. Hot was a whole lot different with a starting temperatures of 45 and increased to 47 the response happened swiftly in about 5 mere seconds for it to begin and end.

The information I gathered was accurate in what would happen and that's what happened in the test. It said hot temperatures reaction is faster because it has far more energy in it but when frigid and medium the heat is much slower specifically for the chilly. Some parts of the research weren't fully correct but some of computer was.

My hypothesis was backed for this test I did forecast that the hotter the faster response but cold has a much more slower response. Hot warms up everything supplying it far more energy to do products so when it extends to a curtain high temperature a reaction begins. Chilly has a slower effect because it has a freezing exactly like humans when we get a chilly we have no energy at all and cannot do anything.

The this may be used is learning the right heat to use to craft medals or maybe products on the whole or to test for what's the right temperatures for plant life and stuff to develop.

Evaluation:

The experiment gone well in the beginning and all through except for a couple of miss calculation with our choice of measuring. There was a bit to much HCI added to test when we should have got less of it, when they elements mixed it almost overflowed out of the beaker. However in the previous test everything still finished up as the same results and completed with no theatre. The team have well but sometimes one member kept touching and ruining that which we just set up. A couple of things that may be improved is the team work and making sure we do our computations right therefore the beaker doesn't almost overflow.

Conclusion:

The full experiment went mainly perfect but it was fixed in the long run. Evan that people have some bad teamwork and miss computations we got it done. Our results were normal and odd the reaction gone fantastic as well do the time. Our calculations were a lttle bit off with a little too much but all resolved in the end. Things that could be improved the next time is the team work. It's the key part for a perfect experiment. Some things that went fantastic would need to of been enough time we go each one down and the perfect times and temperature ranges. If all the bad part were removed it could have been the perfect test.
