1)
Volume = 19 / 1000 = 0.019 L
n = M * V
n = 0.100 * 0.019
n = 0.0019 moles
__________________________
2)
M₁ * V₁ = M₂* V₂
5.0 * V₁ = 1.0 * 152
5.0 V₁ = 152
V₁ = 152 / 5.0
V₁ = 30.4 mL

Answer:
A synthesis reaction occurs when two or more reactants combine to form a single product. ... Replacement reactions occur when elements switch places in compounds. In a single replacement reaction, one element takes the place of another in a single compound. In a double replacement reaction, two compounds exchange elements.
YYe the answer is mechanical
Air Pressure drops more rapidly with altitude in a column of cold air than in warm air.The answers to this question are cold air and warm air, respectively.
<span>Cold air is known to be dense while warm air is known otherwise to be less thens which makes it move upwards. Cold air experiences more pressure as it moves upwards.</span>
To convert the mass of a compound to formula units, the conversion factor is Avogadro's number, 6.022 x10^23 formula units/ mol and its molar mass. In this case, we are given with 19.0 grams of magnesium chloride which has a mass of 95.21 g/mol. Hence the answer is 1.20 x 10^23 formula units.
