Given the following formula 2 KCIO3 -> 2 KCI + 3 O2 how many moles of O2 can be produced by letting 12 moles of KCIO3 react?

1 answer:

6 0

1st you need to find the mole ratio between KClO3 and O2. To find that you need to take the coefficents of each of the compounds. That gives a ratio of 2:3.

Now we find out how many each unit is:
2x = 12
x = 6

Now we multiply it by 3 to find the number of moles of O2
3(6) = 18 mol O2.

How many grams of oxygen are needed to

Paraphin [41]

Answer:

The value is $M_{o} = 175 g$

Explanation:

Generally the reaction between oxygen and magnesium is

$2Mg_{({s})} + O_2_{(g)} \to 2MgO_{(s)}$

Generally from the law of mass conservation in a chemical reaction we have that

$M_{m} + M_{o} = M_{z}$

Here $M_{m}$ is the mass of magnesium

$M_{o}$ is the mass of oxygen

$M_{z}$ is the mass of magnesium oxide

$425+ M_{o} = 600$

=> $M_{o} = 600 - 425$

=> $M_{o} = 175 g$

An atom has 24 protons and 23 electrons and 28 neutrons what charge does this atom have?

alina1380 [7]

Answer:

Explanation:

the number of protons tells you which element it is in the periodic table, you can notice that there is 1 less electron that then there is protons which means that the element had to give 1 electron away. When you get rid of 1 e- you have 1 proton more that electrons so that's why it's 1+

also the element is Cr

What do all acids produce when dissolved in water

RUDIKE [14]

Answer:

hydrogen ions

Explanation:

Acids are substances that when dissolved in water release hydrogen ions, H+(aq). Bases are substances that react with and neutralise acids, producing water. When dissolved, bases release hydroxide ions, OH-(aq) into solution. Water is the product of an acid and base reacting.
