Which gas is evolved when hydrochloric acid is added over a piece of marble in one test tube and on zinc granules in the second test tube?
Zinc (Zn) reacts with hydrochloric acid (HCl) to produce zinc chloride (ZnCl2), a salt and hydrogen gas (H2). Marble is primarily composed of calcium carbonate (CaCO3) which reacts with hydrochloric acid (HCl) to form Calcium Chloride (CaCl2) which is a salt, water (H2O), and carbon dioxide gas (CO2). The first test tube with water evolves carbon dioxide and the second test tube with zinc granules evolves hydrogen gas.
What else can I help you with?
Will anything happen to a marble which placed in vinegar solution?
No. A marble is made of glass, not marble. Glass will not react with vinegar. Edit - Some antique marbles ARE crafted out of marble or other stone/ rock types. Using ANY sort of chemical to clean them can possibly damage the surface finish or even worse, cause the marble to break or split. I happen to own a few antique marbles from the 1880's to the early 1900's. To clean them use a damp, warm soft cloth. Try checking each marble by carefully rubbing a small portion of a marble before cleaning the entire marble(some marbles are sun hardened clay, and getting one wet can damage them). One other method to identify the material your marble(s) are made out of - try a local rock shop. Most rock shop owners can identify what your marble is made from, if it is a naturally occurring rock. They might even be able to provide the possible value of your marble(s), but you should ALWAYS get a second opinion for any value appraisals.
What is the name of the compound whose formula is HCL?
No such compound as 'HCL'. However, if you mean 'HCl'. Then it is hydrochloric acid. NB When writing chemical formula, a single letter element is ALWAYS a CAPITAL letter ( (H) Hydrogen) . A two letter element is ; first letter is a capital letter and the second letter is lower/small case ( (Cl) Chlorine) ; NOT (CL). This is the recognised international standard. NNB There is no element with a single letter 'L'.
How could you determine the densities of two different fluids without mixing them together?
1) determine the density of the first fluid 2) determine the density of the second fluid step 1) and step 2) are easy. just measure the volume and the mass and use the formula: "density = mass/volume" you can also... ~put the liquids in beakers (same amount in both) ~get a little marble ~drop the marble in one of the beakers ~use a timer to time how long it takes the marble to reach the bottom. ~take the marble out or if you have another marble use that ~drop the marble into the second fluid ~time how long it takes to reach the bottom ~the fluid with the less time should be the one that is denser ( you don't have to use marbles, you can use any other two object that are and weight the same).
What is the chemical formula of C and Cl?
Generally, when only hydrogen and chlorine are being bonded together, you can get two compounds. First is hydrogen chloride, a gas at room temperature. The second is hydrochloric acid, which is hydrogen chloride dissolved in water, called an aqueous solution. The chemical formula for both hydrogen chloride and hydrochloric acid is the same if you don't include the subscripts of their states. hydrogen chloride has the formula HCl(g) hydrochloric acid has the formula HCl(aq)
Is hydrochloric acid mixture or compound?
Yes, calcium chloride is considered a type of homogeneous mixture. This is because it is a compound, and compounds are homogeneous.
What is vullaby's second evolved form on Pokemon black?
Vullaby only has one evolved form which is its evolved form of Mandibuzz. Vullaby does not have a second evolved form.

A marble has a diameter of 2 cm At what distance would the marble have an angular diameter of 1 arc second?
6.5cm
Does Hydrochloric acid kill citric acid in your stomach?
First off. You should NOT be drinking hydrochloric acid. Second, hydrochloric acid added to another acid is just that, more acid.
How do you measure the speed of a marble?
You can measure the speed of a marble by using a stopwatch to record the time it takes for the marble to travel a known distance. Divide the distance by the time to calculate the speed in units such as meters per second or feet per second. Alternatively, you can use a motion sensor or tracking software to measure the speed of the marble in real time.
If A bag contains 3 red marbles and 5 purple marbles One marble is drawn at random and not replaced Then a second marble is drawn at random What is the probability that the first marble is purple and?
3/5
What level does the second evolved form of gible evolve at?

If there are 3 red 4 blue and 5 yellow marbles what is the probability of pulling a red or blue marble vs the probability of pulling a red marble the first time and a blue marble the second time?
Pr(Red or Blue) = 0.5833...Pr(R on first pull and Blue on second pull) = 0.0533...
A bag contains 6 purple marbles and 7 white marbles Two marbles are drawn at random One marble is drawn and not replaced Then a second marble is drawn What is the probability that the first marble?
There are 13 marbles in total. The order is specified.P(1st is white and the 2ndis purple) = (7/13)(6/12) = (7/13)(1/2) = 7/26.
When a marble hits a row of marbles why does only one marble fly of?
When a marble hits a row of marbles, only one marble flies off due to the conservation of momentum. The kinetic energy from the first marble is transferred to the second marble at the end of the row, causing it to move while the others remain stationary. It's a chain reaction that propagates the energy through the row.
Largest marble made dome in the world?
The largest marble dome in the world is the dome at St. Peter's Basilica in Rome. The Minnesota State House and the Taj Mahal are second and third.
Is it possible for a marble to go 10 ft per sec?
Yes, it is possible for a marble to travel at 10 ft per second or even faster depending on the force applied to it and the surface it is rolling on. The speed of the marble will be influenced by factors such as its size, weight, and friction.
