What is the pH of 2M HNO3?
The pH of a 2M HNO3 solution is approximately 0. This is because nitric acid (HNO3) is a strong acid that fully dissociates in water to release H+ ions, resulting in a highly acidic solution with a low pH value.
What is the gas produced when metals react with acids?
Hydrogen gas is produced when metals react with acids. This reaction typically involves the metal displacing hydrogen from the acid to form metal salts and hydrogen gas.
A chemist has m gm of salt water that is m percent salty so how many gram of salt must be added to make a solution that is 2m percent salty?
To convert the solution from m percent salty to 2m percent salty, you need to add m/2 grams of salt. This will ensure that the ratio of salt to water in the solution is doubled, resulting in a 2m percent salty solution.
What is the pH of 2M hcl?
The pH of a 2M HCl solution is around 0. This is because HCl is a strong acid that dissociates completely in water to produce H+ ions, leading to a highly acidic solution.
What would a balanced equation look like if a solid metal reacts with water to produce aqueous sodium hydroxide and hydroxide gas?
When sodium and water react, they will produce aqueous sodium hydroxide and hydrogen gas. Here's the balanced equation for that reaction: 2Na + 2H2O --> 2NaOH + H2 This reaction is violently exothermic and should be done under very safe and controlled conditions. The hydrogen gas will likely ignite, which itself is a different reaction: 2H2 + O2 --> 2H2O
2m equals 26 what is the value of m?
2m = 26m = 26/2m = 13
2m equals 3 what is the value of m?
2m = 3m = 3/2Therefore m = 1.5
What is the value of 2m for m equals 1 2 and 3?
There is NO single value (THE vallue) for 2m when m takes three different values.
What is m if 2m-9 equals 12?
2m - 9 = 12→ 2m - 9 + 9 = 12 + 9→ 2m = 21→ 2m ÷ 2 = 21 ÷ 2→ m = 101/2 = 10.52m - 9 = 12Add 9 to each side of the equation:2m = 21Divide each side by 2 :m = 10.5
What is -2m plus 92?
It is the expression -2m + 92. This cannot be evaluated without knowing the value of m.
What is the value of m when 1 over m plus 1 over 2m equals 6?
1/m + 1/2m = 6 LCD is 2m (2 + 1) / 2m = 6 3/2m = 6 3/6 = 2m = 1/2 m = 1/4
What is the value of the McClure Magazine 1920?
Worth over $2m.
2M plus 2p equals 16 what does p equal?
You can solve this for p:2m + 2p = 162p = 16 - 2mp = 8 - mIf you supply a value for "m", you can then calculate p.You can solve this for p:2m + 2p = 162p = 16 - 2mp = 8 - mIf you supply a value for "m", you can then calculate p.You can solve this for p:2m + 2p = 162p = 16 - 2mp = 8 - mIf you supply a value for "m", you can then calculate p.You can solve this for p:2m + 2p = 162p = 16 - 2mp = 8 - mIf you supply a value for "m", you can then calculate p.
What is 2m divided by 5?
0.4
What is 2m - 5 over 9?
It is simply 2m - 5/9, nothing more, nothing less. It cannot be simplified or factorised. It cannot be evaluated without knowing the value of m.
What is 30 percent of 2m?
30 percent of 2m = 0.6m30% of 2m= 30% * 2m= 30%/100% * 2m= 6/10m or 0.6m
2m is 50 cm?
2m is 200cm..
