3 0

Answer:

b) Baking soda

Explanation:

Baking soda is sodium hydrogen carbonate, NaHCO₃.

It reacts with water according to the equation

NaHCO₃ + H₂O ⇌ H₂CO₃ + NaOH

Thus, baking soda is a base because it increases the concentration of hydroxide ions in water.

<em>Water</em> is <em>neutral</em>.

<em>Lemon juice</em> is an <em>acid</em> because it contains citric acid.

An <em>insulator </em>is a substance that does not conduct electricity. Insulators are <em>neither acidic nor basic</em>.

Glucose is stirred into water to form a solution. In this case, what are the glucose and water?
Alex_Xolod [135]

The correct option is C.

When glucose is stirred into water to form a solution, then glucose is the SOLUTE and water is the SOLVENT. A solute refers to a substance that is dissolved in a solvent. For instance, salt is the solute that is dissolved in salt solution. A solvent on the other hand refers to the liquid into which the solute was dissolved. For instance, in the case of salt solution, water is the solvent, because it is used to dissolve the salt.

A Gas OCCUPIES 525ML AT A PRESSURE OF 85.0 kPa WHAT WOULD THE VOLUME OF THE GAS BE AT THE PRESSURE OF 65.0 kPa
german

Boyle's law of ideal gas: This law states that the volume of a gas is inversely proportional to its pressure at a constant temperature. Acc to this law we can write the relation of pressure and volume as:

PV=Constant

That means:

P_{1}V_{1}=P_{2}V_{2}

From that equation we can calculate Volume of gas at a certain pressure:

P₁=Initial pressure

V₁=Initial volume

P₂=Final pressure

V₂= Final volume

Here P₁, initial pressure is given as 85.0 kPa

V₁, initial volume is given as 525 mL

P₂, final pressure is 65.0 kPa

P_{1}V_{1}=P_{2}V_{2}

so,

V_{2}=85\times 525\div 65

=686 mL

Volume of gas will be 686 mL.
