Toluene (C7H8) and nitric acid (HNO3) are used in the production of trinitrotoluene (TNT, C7H5N3O6), an explosive. C7H8 + HNO3 =
olga55 [171]
  The mass in grams  of nitric  acid that is required  to react  with 454g C7H8 is 932.72  grams

     calculation
find the  moles  of C7H8  used
moles = mass/molar mass

= 454 g/92  = 4.935  moles

balanced reacting  equation

C7H8  +3 HNO3  = C7H5N3O6  +3 H20
by  use of mole ratio between  C7H8  to  HNo3  which is  1:3  the moles of  HNO3  =4.935  x3 = 14.805  moles

mass of HNo3  =  moles  x molar mass
= 14.805  x 63  = 932.72  grams

part B

the  mass of  C7H5N3o6 = 2045.5 grams

calculate the moles of C7H8
= 829 g/92  g/mol  = 9.011  moles

by use of mole  ratio  between C7H8 to C7H5N3O6  which is  1:1  the moles of  C7H5N3O6  is also  = 9.011  moles

mass of  C7H5N3O6  is therefore  =  moles x molar mass

=9.011 x227  = 2045.5 grams

What is the correct ionic formula when mg2+ and p3− react?
Mumz [18]

Answer: Ionic formula will be Mg_3P_2.

Explanation: Mg^{2+} and P^{3-} ions will form a ionic compound. Ionic compounds have both metals and non-metals.

Here Mg^{2+} is a metal and P^{3-} is a non-metal.

The net charge on any compound must be 0.

So we need 2 phosphate ions to balance the charge on Mg^{2+} ions. Similarly we need 3 Magnesium ions to balance the charge on P^{3-} ions.

Criss-crossing the charges, we will get the formula as Mg_3P_2

Criss-crossing is shown in the image below.

Which model best shows the movement of oxygen during photosynthesis
Alexxandr [17]
All photosynthesis eukaryotic cells contain chloroplast that use the radiant energy of sunlight to convert carbon dioxide and water into carbohydrates. As a byproduct of photosynthesis, oxygen gas is also released into the atmosphere through tiny openings in the leaves called stomata

Calculate the freezing point (0°C) of a 0.05500 m aqueous solution of glucose.
Rainbow [258]

Answer:

-0.1767°C (Option A)

Explanation:

Let's apply the colligative property of freezing point depression.

ΔT = Kf . m. i

i = Van't Hoff factot (number of ions dissolved). Glucose is non electrolytic so i = 1

m = molality (mol of solute / 1kg of solvent)

We have this data → 0.095 m

Kf is the freezing-point-depression constantm 1.86 °C/m, for water

ΔT = T° frezzing pure solvent - T° freezing solution

(0° - T° freezing solution) = 1.86 °C/m . 0.095 m . 1

T° freezing solution = - 1.86 °C/m . 0.095 m . 1 → -0.1767°C
