One of the atoms involved must be a metal and the other a nonmetal
Answer:
<h2>30.2 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
volume = final volume of water - initial volume of water
From the question
volume = 35.9 ml - 25.8 ml = 10.1 mL
We have
mass = 2.99 × 10.1 = 30.199 g
We have the final answer as
<h3>30.2 g</h3>

Answer:
Tides . hope this helps
Explanation:
the tidal force causes earth and its water to bulge out on the side closest to the moon
Standard enthalpy change of neutralization is the enthalpy change when 1 mole of water is produced by the reaction of an acid and a base under standard conditions.
Enthalpy change of neutralization:
- Every time enthalpy change of neutralization is calculated, one mole of water is produced.
- Heat is released when an acid and an alkali react, hence enthalpy changes of neutralization are always negative.
- The values are always quite comparable for reactions involving strong acids and alkalis, falling between -57 and -58 kJ mol-1.
- If the reaction is the same in each case of a strong acid and a strong alkali, the enthalpy change is similar.

Answer:
0.354 molal
Explanation:
The molarity (M) or the concentration of a solution is defined as the number of moles of a compound in the solution per liter of solution (mol/L), whereas molality, is defined as the number of moles of a compound in the solution per kg of the compound (mol/kg).
Given that the density of the solution is 1.202 g/mL, which is equivalent to 1.202 kg/L. Since the prefix mili- denotes a factor of one thousandth ( 
) and kilo- denotes a factor of one thousand ( 
),
.
To calculate the corresponding molality of the solution, the formula
is used.
Therefore,
