Answer:- 1.050 mL
Solution:- Volume is an additive property. So, we add all the three given volumes to get the total volume.
Total volume = 
Since in addition, we go with least decimal places, the answer must have three decimal places as all the given numbers have three decimal places each.
Hence, the total volume should be reported as 1.050 mL.
The alcohol has an oxygen atom single-bonded to hydrogen and single-bonded to a carbon-containing group.
<h3>What is alcohol? </h3>
Alcohol is defined as the organic compound which is derived from an hydrocarbon by replacing one hydrogen by hydroxyl group(—OH).
The general formula of alcohol is ROH.
where, R is the alkyl group.
The first member of alcohol is ethanol.
<h3>Physical properties of alcohol</h3>
- Alcohols are colourless.
- They give a sweet smell except for glycerol and few lower alcohols.
- They are flammable and produce a blue flame on burning.
- They don't produce any kind of smoke while burning.
- Alcohol are liquid at room temperature.
Thus, alcohol is an organic compound which contain an oxygen atom which is single-bonded to hydrogen and single-bonded to a carbon-containing group.

Answer:
They have the same mass
Explanation:
The two blocks have the same mass. Mass is the quantity of matter contained in a substance. Therefore, the two bodies have the same mass.
The weight is a measure of mass and gravity. The gravity on earth differs from that on the moon. Therefore, the two bodies have different weights.
Their volume is also different since one body is larger than the other. Therefore, density which is the mass per unit volume will also differ.
Answer:
Hydrogen is the lightest element in the periodic table. Hydrogen is a gas of diatomic molecules and is colorless, odorless, non-toxic, and highly combustible. It is the most abundant chemical substance in the universe as it constitutes roughly 75% of all normal matter.
Answer: Here are the complete options.
A spontaneous process is one that occurs very quickly. A process that is spontaneous in one direction is nonspontaneous in the other direction under a given set of conditions, provided the system is not at equilibrium. A spontaneous process is one that occurs without continuous input of energy from outside the system. A process is spontaneous if it must be continuously forced or driven.
The correct option is
A spontaneous process is one that occurs without continuous input of energy from outside the system.
A process that is spontaneous in one direction is nonspontaneous in the other direction under a given set of conditions, provided the system is not at equilibrium
Explanation:
spontaneous process is one that occurs without continuous input of energy from outside the system and occur on its own because spontaneous processes are thermodynamically favorable characterized by a decrease in the system's free energy, they do not need to be driven by an outside source of energy. Which means that the initial energy is higher than the final energy.
A process that is spontaneous in one direction is nonspontaneous in the other direction under a given set of conditions, provided the system is not at equilibrium which will result to The sign of ΔG will change from positive to negative (or vice versa) where T = ΔH/ΔS. In cases where ΔG is: negative
