What is the balanced equation for magnesium and 6M HCl?
The 6M is irrelevant for this equation.
Balanced Equation: Mg + 2HCl -> MgCl2 + H2
Eliseo couldn't find the 6m hcl and so used 6m hno3 for testing the metals instead his logic both are strong acids exlpain how the results of the experiment would have been different?
How much water must be mixed with concentrated hydrochloric acid to prapare 50cm3 of 6m hcl solution?
There are two ways (at least) to work this. Conceptually, you need 8 bottles of 125mL to make 1L, and, therefore, 16 bottles to make 2L. The HCl gets divided out into those 16 bottles of water, so 6M/16 = 0.4M (you have to round up from 0.375. The data, 6M, has one significant number, so your answer does, too). Another way to think of it is to think of the amount of HCl in…
No, 56cm is not more than 6m because 56cm < 6m. Notes: 1. Clarify the question "Is 56cm or than 6m?" to "Is 56cm more than 6m?" 2. Convert 56cm to meters (56 * 1/100 = .56m 3. Compare .56m to 6m: .56m < 6m 4. Answer the question: "No, 56cm is not more than 6m." ====== Answer 1: No. 6m= 600cm so 6m is greater than 56cm
How much light can a telescope with a 6 meters objective mirror collect compared to that of a telescope with a 9 meters objective?
3m+4 = 6m-48 3m-6m = -48-4 -3m = -52 Divide both sides of the equation by -3 to find the value of m remembering that a - divided into a - is equal to a +: m = 17 and 1/3 Or can just not devide both sides with -3 , cuz when you put -3 on the other side, you'll get -52 divided to 3 and get to the answer of -17.33(3) :D Cheers…
If you're talking about the lab bottles, "dilute" means "6M" (which is not really all that dilute) and "concentrated" means "straight out of the stock bottle", i.e very nearly pure acid in most cases (of the common laboratory acids you'll see in a college general chemistry lab, HCl is the only one that isn't "pure", because pure HCl is a gas; HCl out of a stock bottle is generally about 12M).
First it's HCl (with a lowercase L) not HCI. But as to the small amount of acid needed to provide the increase: HCl is a strong acid and so it completely dissociates to produce H+ ions, so the H+ concentration equals the HCl(aq) concentration. A decrease in pH from 7 to 6 represents an increase in H+ ions from 10-7M to 10-6M. This would therefore only require the addition of about 3.65X10-5 grams of HCl…
