During cellular respiration<span>, glucose is broken down in the presence of oxygen to produce carbon dioxide and water,energy is </span><span>released.</span>
Answer:
0.017 mol
Explanation:
CH3COOH - acetic acid - we can write as C2O2H4
From formula C2O2H4 we can see that ratio C: O = 2:2 = 1:1, so number of moles C and O are the same.
So if we have 0.017 mol C, we should have 0.017 mol O.
<span>ZnS + O --> ZnO + SO
Okay so first you have to count up the number of elements on each side of the equation. Your objective is to have the same number of each element on both sides.
Left Side:
Zn - 1
S - 1
O - 1
Right Side:
Zn - 1
S - 1
O - 2
Since there are two oxygens on the right side, you have to add a coefficient of 2 to the oxygen on the left side. The coefficient tells us that that element or molecule is being multiplied by the value of coefficient. Since we're adding a coefficient of 2 to the oxygen on the left side, there are now 2 oxygens on that side. Because that is the same amount of oxygen as on the right, the equation is now balanced.
Your final equation should look like this: </span>ZnS + 2O --> ZnO + SO
In conclusion, the answer is 2.
Answer:
sodium ions and chloride ions
chloride ion
sodium ion
Explanation:
Ionic substances are composed of ions. When you dissolve an Ionic substance in water, the ions that compose the substance together with water molecules are present in solution.
Hence, when sodium chloride is dissolved in water, sodium ions and chloride ions are released in solution.
Water has a dipole moment. Hence, the chloride ions are attracted to hydrogen (the positive end of the dipole) while sodium ions are attracted to oxygen (the negative end of the dipole).
This is how the solid is dissolved in water.
Answer:
it is necessary to keep our sense organ clean and healthy for if don't clean our sense organ clean we may suffer from many disease like if we don't clean eyes we can't see anything, if we don't clean ear we can't listen anything, and if we don't clean nose it hard for breathing, and if we don't cleanour tounge should be dry and become our breathe smell is very bad, and if we don't clean skin we may suffer from many disease and that may we get cancer also.
