Answer:
T₂ = 478.93 K
Explanation:
Given that,
Initial pressure, P₁ = 178 kPa
Initial temperature, T₁ = 37°C = 310 K
Final pressure, P₂ = 275 kPa
We need to find the new temp of the air in the tire, assuming the volume is constant. We know that,
So, the new temperature is equal to 478.93 K.
Amino acids are the monomers that make up proteins. Each amino acid has the same fundamental structure , which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom.

Explanation: Balance the reaction of KOH + H3PO4 = K3PO4 + H2O using this chemical equation balancer!
Answer:
a) As I remember "the atomic spectra" of bohr
1- Existence of a positively charged nuclei in the centre of the atom
2- Number of negatively charged electrons = number of positive charges ported by the atom.
3- Electrons navigate in fixed energy levels , with a high speed without gain or loose energy
4- centrifugal force is in equilibrium with attraction force.
5- The empty space between energy levels is forbidden for electrons.
Answer:
Option B. 1 calcium, 2 oxygen, and 2 hydrogen
Explanation:
The number of each atoms present in Ca(OH)2 can be summarised as follow:
Calcium (Ca) = 1
Oxygen (O) = 2
Hydrogen (H) = 2
From the above illustration, we can see clearly that Ca(OH)2 contains 1 calcium, 2 oxygen and 2 hydrogen.
