Answer:

61 atm

Explanation:

You can calculate osmotic pressure using the following equation:

π = <em>i </em>MRT

In this equation,

-----> π = osmotic pressure (atm)

-----> <em>i</em> = van't Hoff's factor

-----> M = molarity (M)

-----> R = Ideal Gas Constant (0.08206 atm*L/mol*K)

-----> T = temperature (K)

The van't Hoff's factor is the amount of ions the substance dissociates into. Since sugar does not dissociate, this value is 1. After converting Celsius to Kelvin, you can plug the values into the equation and simplify.

<em>i</em> = 1                                 R = 0.08206 atm*L/mol*K

M = 2.5 M                      T = 25 °C + 273.15 = 298.15 K

π = <em>i </em>MRT

π = (1)(2.5 M)(0.08206 atm*L/mol*K)(298.15 K)

π = 61 atm

During active transport, substances move from regions of blank concentration to regions of blank concentration
Annette [7]
<span>Active transport runs counter to facilitated diffusion. In active transport, molecules move against the concentration gradients, running from areas of lower concentration to areas of higher concentration. This is where energy is used.</span>

Answer:

Question 1.

a. the product of the reaction above that contains calcium is calcium chloride, CaCl₂.

b. hydrochloric acid, HCl is the reactant that contains hydrogen

c. the product water, H₂O contains hydrogen

d. the reactant, calcium carbonate, CaCO₃ contains carbon

e. The product carbon (iv) oxide contains carbon

Question 2:

a. atoms of hydrogen and oxygen bonded together as a single compound known as water molecules are present at the start of the reaction

b. two molecules of water are present at the start of the reaction

c. two individual atoms of hydrogen and oxygen existing as molecules are present at the end of the reaction.

d. at the end of the reaction, two molecules of hydrogen and one molecule of oxygen are present.

Question 3:

a. total mass of products = 187 g

b. 10 g of magnesium will be found in the magnesium sulfate

Explanation:

Question 1: The equation of the reaction between calcium carbonate and hydrochloric acid is given as follows:  + 2HCl ---> CaCl₂ + H₂O + CO₂

a. the product of the reaction above that contains calcium is calcium chloride, CaCl₂.

b. the reactant, hydrochloric acid, HCl contains hydrogen

c. the product water, H₂O contains hydrogen

d. the reactant, calcium carbonate, CaCO₃ contains carbon

e. The product carbon (iv) oxide contains carbon

Question 2: the equation of the reaction in which water is broken down to hydrogen and oxygen is as follows: 2H₂O ----> 2H₂ + O₂

a. atoms of hydrogen and oxygen bonded together as a single compound known as water molecules are present at the start of the reaction

b. two molecules of water are present at the start of the reaction

c. two individual atoms of hydrogen and oxygen existing as molecules are present at the end of the reaction.

d. at the end of the reaction, two molecules of hydrogen and one molecule of oxygen are present.

Question 3: The equation of the reaction between magnesium and sulfuric acid is given as follows: Mg + H₂SO₄ ---> MgSO₄ + H₂

molar mass of Mg = 24.0 g; molar mass of H₂SO₄ = 98.0 g

a.  According to the law of conservation of mass, when 37.0 g of magnesium is reacted with 150 g of H₂SO₄, the total mass of products of the reaction = total mass of reactants = 150 + 37 = 187 g

b. if Chinua starts with 10 g of magnesium, the same 10 g of magnesium will be found in the magnesium sulfate
