Answer: Option (D) is the correct answer.

Explanation:

Significant digits are defined as the digits which contribute meaning to the resolution of a number.

For example, if a digit is 40.0 ml then zero placed after the decimal point is not considered a significant because it doesn't contribute any value to the total quantity or number.

But zero placed in 40 will be considered significant because it tells us the number is forty. Hence, in 40.0 there are only 2 significant digits.

Similarly, in 4010,0 mL there are in total 5 significant digits.

Thus, we can conclude that there are 5 significant digits in the volume measurement 4010,0 mL.

60 grams of ice will require _____ calories to raise the temperature 1°C.
guajiro [1.7K]

Answer:

60 grams of ice will require 30.26 calories to raise the temperature 1°C.

Explanation:

The amount of heat (Q) to raise the temperature of 60.0 g of ice by 1°C can be calculated from:

<em>Q = m.c.ΔT,</em>

where, Q is the amount of heat released or absorbed by the system.

m is the mass of the ice (m = 60.0 g).

c is the specific heat capacity of ice (c = 2.108 J/g.°C).

ΔT is the temperature difference (ΔT = 1.0 °C).

∴ Q = m.c.ΔT = (60.0 g)(2.108 J/g.°C)(1.0 °C) = 126.48 J.

<em>It is known that 1.0 cal = 4.18 J.</em>

<em>∴ Q = (126.48 J)(1.0 cal / 4.18 J) = 30.26 cal.</em>

Which instrument is most often used to measure acid volume before a titration begins?
Darya [45]

<span>Good Morning!
 
To measure the volume of an acid we use in the laboratory an instrument called burette (a). This instrument is used to calculate the volumes of chemical solutions. At first glance, these tools may be confused with syringes, but have different functions.
