The given question is incomplete. The complete question is:
Calculate the number of moles and the mass of the solute in each of the following solution: 100.0 mL of 3.8 × 10−5 M NaCN, the minimum lethal concentration of sodium cyanide in blood serum
Answer: The number of moles and the mass of the solute are 
and 
respectively
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in ml
n = moles of 
= 
Thus the number of moles and the mass of the solute are and respectively
The balanced chemical reaction is written as:
<span>Zn(s) + 2HCl(aq) = ZnCl2(aq) + H2(g)
</span>
We are given the amount of the reactant zinc to be used in the reaction This amount would be the starting point for the calculation. It is as follows:
5.00 mol Zn ( 1 mol H2 / 1 mol Zn ) (2.02 g H2 / 1 mol H2 ) = 10.1 g H2
Therefore, the correct answer is the second option.
Answer:
Goodness of fit
Explanation:
The goodness of fit - it is proposed by Thomas and chess in 1977. This term is used to defined coordination of child temperament and environment. while poorness of fit defines when temperament is not accommodated.
The goodness of fit is generally good for children's best learning. it is basically related to individual temperament and their social environment
Answer: what is the effect of ( pressure ) on the volume of a gas
If the pressure on a gas is increased, then it’s volume will ( decrease ) because the gas molecules will ( be pushed closer together)
