Answer:
D
Explanation:
The proberties of the substances that are produced are different from the properties of the original substances.
<span>Mole ratios are important to stoichiometric calculations because they bridge the gap when we have to convert between the mass of one substance and the mass of another.</span>
Answer:
Moles of NaNO2 = 0.158
Moles of HNO2 final = 0.098
Explanation:
Given
Moles of HCl = 12
Moles of HNO2 = 0.11
Moles of NaNO2 = 0.170
HCl +NaNO2 --> HNO2 + NaCl
1 mole of HCl react with one mole of NaNO2 to produce 1 mole of NaCl and 1 mole of HNO2
Moles of NaNO2 = 0.17 - 0.012 = 0.158
Moles of HNO2 final = 0.11 - 0.012 = 0.098
Answer: The given statement is False.
According to alternative hypothesis, observed difference exists between research variables, which does not occur by chance.
Whereas, a non directional alternative hypothesis has no definite directions of the difference but a certain difference does exist.
Thus, the given statement is False.
The interaction between biosphereand hydrosphere is that hydrosphere provides water for the biosphere to function, grow, and live
