Answer:
Explanation:
1. Find the empirical formula of a compound that has 36% of Calcium (Ca), 64% of Chlorine (Cl).
2. Find molar mass of each component: Ca=40.078, Cl=35.453
3 Convert to moles: Ca=0.8982484155896, Cl=1.8052068936338
4 Find smallest mole value: 0.8982484155896
5 Divide all components by the smallest value: Ca=1, Cl=2.0096967189738
6 Round to closest whole numbers: Ca=1, Cl=2
7 Combine to get the empirical formula: CaCl2
Answer:
350J
Explanation:
Based on the first law of thermodynamics, which is the law of conservation of energy, energy can neither be created nor lost but can only be transformed. This implies that energy input of a system must equate the energy output as no energy can be lost.
In this case regarding an unlit match that contains 1000J of chemical energy. It burns to emit light energy and heat/thermal energy. If the amount of emitted thermal energy measured is 400J and the remaining/left over amount of chemical energy is 250J, this means that the missing amount of energy has been emitted as light energy.
To find the amount of light energy emitted, we say;
Amount of chemical energy - (thermal energy emitted + remaining chemical energy)
= 1000 - (400 + 250)
= 1000 - 650
= 350J
Hence, the amount of light energy emitted is 350J. This satisfies the law of conservation of energy because the output energy is equal to the total energy in the system.
Peptide bonds, hydrogen bonds, disulfide linkages, van der Waals, and electrostatic forces of attraction are the chemical bonds that stabilize the different structures in primary, secondary, tertiary, and quaternary structures.
The advanced structure of proteins gives rise to two kinds of major molecular shapes which are fibrous as well as globular structures. The main forces which are involved in stabilizing the secondary along with the tertiary structures of proteins include hydrogen bonds, disulfide type linkages, van der Waals attraction, and electrostatic forces of attraction.
The primary structure is generally determined by adjoining peptide bonds where the link is adjoining amino acids in sequential order. Tertiary structure is determined by the existence of disulfide bonds in between hydrophobic interactions as well as cysteine residues whereas the quaternary type structure is determined by multiple subunits of a protein that undergo various interactions.
Hydrogen bonds exist in a protein molecule as its large number can form between adjacent regions of the polypeptide chain in folded form and stabilize its three-dimensional kind of shape.

Answer:
= 2.33 L
Explanation:
V1/T1 = V2/T2
V1 = 3.0 L
T1 = 78 + 273
= 351 K
At s.t.p the temperature is 273 K and pressure is 1 atm.
V2 = ?
T2 = 273 K
V2 = V1T2/T1
= (3.0 ×273)/351
= 2.33 L

Explanation:
Both oxygen and dinitrogen (1) oxide are known to rekindle a glowing splint. However, oxygen is an odorless gas while dinitrogen (1) oxide has a faint smell and has an effect on the central nervous system.
Also, the combustion of dinitrogen (1) oxide produces brown fumes of nitrogen IV oxide.
Finally, when dinitrogen (1) oxide and oxgen are both heated with copper, residual nitrogen gas is left with dinitrogen (1) oxide while no residual gas is left with oxygen.
