Answer:
Explanation:
Because unlike ionic bonds (metal and a non-metal) where electrons are "stolen", covalent bonds are defined by the sharing of electrons between non-metals.
Answer:
The answer to your question is: Q = 1383.06 J
Explanation:
Data
mass = 0.740 g
Initial Temperature = 23.4°
Final Temperature = 26.9°
Cp = 534 J/°C
mass of water = 675 ml
Q = ?
Formula
Q = mCpΔT
Process
Q = (0.740)(534) (26.9 - 23.4)
Q = (0.740)(534) (3.5)
Q = 1383.06 J
Like the diagram we can see the the products of reaction are obtained with a amount of heat under the heat of reactants... so the reaction is exothermic and the Ea = E* - Eproducts = 100 - 40 = 60 kJ
Answer:
Explanation:
Alleles are the pairs of genes occupying a specific spot on a chromosome. That spot is called locus. For example, a pair of alleles controlling the same trait, i.e. eye color: one allele codes for blue eyes, another allele for brown eyes.

Explanation:
he laws of thermodynamics define a group of physical quantities, such as temperature, energy, and entropy, that characterize thermodynamic systems in thermodynamic equilibrium. The laws also use various parameters for thermodynamic processes, such as thermodynamic work and heat, and establish relationships between them. They state empirical facts that form a basis of precluding the possibility of certain phenomena, such as perpetual motion. In addition to their use in thermodynamics, they are important fundamental laws of physics in general, and are applicable in other natural sciences.
Traditionally, thermodynamics has recognized three fundamental laws, simply named by an ordinal identification, the first law, the second law, and the third law.[1][2][3] A more fundamental statement was later labelled as the zeroth law, after the first three laws had been established.
