IVYTECH CHEM 101 MIDTERM || QUESTIONS AND ANSWERS | 2026 UPDATE | GRADED A +.
The definition of a scientific law is ✔️a number of similar observations generalized into a brief statement summarizing past observations and
predicting new ones
Which statement about a hypothesis is TRUE ✔️All of the above statements are true.
Which of the following is an example of a scientific law ✔️In a chemical reaction, matter is neither created nor destroyed.
A sample of wood with a mass of 3.0 grams was burned in an open dish. The ashes weighed 1.2 grams. What happened to the rest of the
wood? ✔️The remaining 1.8 grams was converted into gaseous compounds.
Which statement would NOT be an example of "quantification" ✔️The water in the swimming pool feels colder than it was yesterday.
A popular science demonstration is to take several liquids that will not mix together and "stack" these liquids in a tall glass cylinder. Suppose
the following three liquids were places in the same tall, narrow glass cylinder:
SUBSTANCE DENSITY (g/mL)
vinegar 1.01
motor oil 0.87
corn syrup 1.36
These liquids would stack in which order? ✔️motor oil on top, vinegar in the middle, corn syrup on the bottom
Suppose a boat engine leaks 938 mL of oil into a lake. The mass of this spilled oil is 823 g. The oil will not mix with the lake water. Which
statement is true? ✔️The oil will float because its density of 0.877 g/mL is less than the density of water.
Determine the answer to the following equation with correct number of significant figures:
2.02+8.102-0.0297= ✔️10.09
How many milliliters are in 17.5 L ✔️1.75 x 104 mL
Given the density of Au is 19.3 g/cm3, determine the mass of gold (in grams) in an ingot with the dimensions of 10.0 in x 4.00 in x 3.00 in. ✔️3.80
x 104
The correct decimal representation of 6.453 x 103 is: ✔️6,453
A plastic block has dimensions of 2.2 cm x 3.0 cm x 1.5 cm and a mass of 12.4 grams. Will the block float in water and why ✔️No, because the
density of the block is 1.3 g/mL which is greater than the density of water.
How many grams are in 1.48 x 10^7 μg? ✔️14.8
Determine the answer for the equation below with correct number of significant figures:
1.2*1.79= ✔️2.1
The correct number of significant figures in the number 0.027090 is: ✔️5
Physical properties are ✔️those that a substance displays without changing its composition
Which type of energy is associated with the burning of gasoline ✔️chemical
Which type of energy is associate with motion ✔️kinetic
Which state of matter has atomic spacing that is close together and indefinite shape? ✔️liquid
