Answer:

A peptide

Explanation:

A peptide bond is a type of amide covalent chemical bond which links two successive alpha amino acids, it is also known as Eupeptide bond it is formed when the chemical bond that exists between two molecules in which the carboxyl molecule acts with the amino group on the other molecule which leads to the liberation of water.

A balloon is filled with 2.5 L of helium at 1 atm of pressure. If the pressure
ch4aika [34]

Answer:

5 L

Explanation:

Given data

  • Initial pressure (P₁): 1 atm
  • Initial volume (V₁): 2.5 L
  • Final pressure (P₂): 0.50 atm
  • Final volume (V₂): ?

For a gas, there is an inverse relationship between the pressure and the volume. Mathematically, for an ideal gas that undergoes an isothermic change, this is expressed through Boyle's law.

P_1 \times V_1 = P_2 \times V_2\\V_2 = \frac{P_1 \times V_1}{P_2} = \frac{1atm \times 2.5L}{0.50atm}= 5 L

SITUATION # 2: Every morning we drink milk to strengthen our bones. You
hram777 [196]

Answer:

Amount of milk in grams = 95 gram

Explanation:

Given:

Volume of mix solution = 100 ml

Percent of powered milk = 5%

Find:

Amount of milk in grams

Computation:

Assume;

1 ml = 1 gram

Amount of milk = 100 - 100(5%)

Amount of milk = 100 - 5

Amount of milk = 95 ml

Amount of milk in grams = 95 gram

When 1.0 mole of MgSO4 is dissolved in water contained in a calorimeter, the temperature of the water and dissolved ions increas
KatRina [158]

Answer: negative , from , to , exothermic

Explanation:

An endothermic reaction is a type of chemical reaction in which energy is absorbed from the surrounding. The temperature of the surrounding decreases.

An Exothermic reaction is a type of chemical reaction in which energy is released into the surrounding. The temperature of the surrounding increases.

Endothermic reactions are those in which heat is absorbed by the system from the surroundings and exothermic reactions are those in which heat is released by the system to the surroundings. \Delta H  for Endothermic reaction is positive and  

As on dissolution of salt, the temperature of water increases, the heat has been released from system into surroundings and thus \Delta H is negative.
