Ima 5% glucose solution, how many grams of glucose would be present per 100mL
Sedaia [141]

Percentage Weight-in-volume is defined as the <em><u>number of grams of a solute in a 100 ml (milliliters) solution.</u></em>

<u />

<u>Percentage Weight-in-volume</u> can tell us about the <em>degree of concentration of a given solution.</em>

<em><u /></em>

The solute can be <em>crystalline or non-crystalline in nature.</em>

<em></em>

The <u>number of grams of glucose</u> present in a <u>5% glucose solution</u> is 5 grams.

  • This question is based on a Percentage Weight-in-volume. The formula states that:

a% of a glucose solution =<u> a grams of glucose in a 100 mL solution</u>

Hence, 5% glucose solution = 5 grams of glucose / 100 mL solution

Therefore, the <u>number of grams of glucose</u> present in a <u>5% glucose solution</u> is 5 grams.

5) Solid silver chloride, AgCl, precipitates when solution of silver nitrate, AgNO3, and iron (111) chloride,
DanielleElmas [232]

The chemical reaction between the reactants:

3 AgNO₃ (aq) + FeCl₃ (aq) → 3 AgCl (s) +  Fe(NO₃)₃ (aq)

Explanation:

We have the following chemical reaction:

3 AgNO₃ (aq) + FeCl₃ (aq) → 3 AgCl (s) +  Fe(NO₃)₃ (aq)

Complete ionic equation:

3 Ag⁺ (aq) + 3 NO₃⁻ (aq) + Fe³⁺ (aq) + 3 Cl⁻ (aq) → 3 AgCl (s) +   Fe³⁺ (aq) + 3 NO₃⁻  (aq)

We remove the spectator ions and we get the net ionic equation:

Ag⁺ (aq) + Cl⁻ (aq) → AgCl (s)

where:

(aq) - aqueous

(s) - solid

HELPPP<br> What do you think caused this land formation ?
Arturiano [62]

Answer:

Erosion/Weathering

Explanation:

Because the rock is exposed to the ocean, the constant push and pull of the water against the rock erodes the material away and moves it elsewhere. The wind likely aided in this process as well. This caused the big gap in the center of the rock.

Click the "draw structure" button to launch the drawing utility. under certain reaction conditions, 2,3−dibromobutane reacts wit
REY [17]

Answer:

Explanation:

According to this. Let's analize the possible products a, b and c.

First, the problem states that we have 2 eq. of base, For this case, let's assume it's KOH. Now, As we are doing a reaction with base, means that this reaction can only take places under conditions of SN2 and E2, a fast reaction that is taking place in only 1 step.

With this in mind, let's analyze product a. This states that it has two sp hybridized carbon, in other words, a triple bond between two carbons. So the product is with no doubt, an alkyne.

Product b has only one sp hybridized carbon, which means that this carbon should cannot be an alkyne because we need two carbon atoms. The only way to have one atom of C sp hybridized, is with two double bonds, so product b would have to a alkene with two double bonds.

Product c do not have sp hybridized carbon, therefore, it only has two double bonds in two different Carbon atoms, so it's another alkene with two double bonds, but in two different atoms of carbon.

Picture attached show the product a, b and c. Hope this can help
