ivanzaharov [21]3 years ago
8 0

Answer:

Beryllium

Explanation:

No. of protons = 4

<em>No. of electrons = 4 (number of protons and neutrons are the same)</em>

No. of neutrons = 5

You need to look at the number of electrons of the outer shell (group no.) there are and how many shells there are (period no.)

Then look at the period table of elements to find the element

When 1 mole of H2(g) reacts with F2(g) to form HF(g) according to the following equation, 542 kJ of energy are evolved H2(g) + F
topjm [15]

Answer: The reaction is exothermic. The value of q is  -542 kJ.

Explanation:

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and  for the reaction comes out to be positive.

Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and  for the reaction comes out to be negative.

Thus H_2(g)+F_2(g)\rightarrow 2HF(g) evolves heat , it is exothermic in nature. The value of q is -542kJ.

balance the reaction equation describing the biological formation of glucose (c6h12o6) with the lowest set of whole number coeff
Ivan

The given reaction equation for photosynthesis whereby, in the presence of light energy from the Sun and chlorophyll, plants synthesize glucose from carbon dioxide and water.  As water is present as a reactant, it doesn’t also appear on the ’products’ side of the equation. So:

Water + carbon dioxide > glucose + oxygen.

As glucose contains 6 carbon atoms, these must be obtained from 6 molecules of CO2. So, overall:

6CO2(g) + 6H2O(l) > C6H12O6(aq) + 6O2(g).

What is photosynthesis?

Photosynthesis is the process  plants and other organisms use to convert light energy into chemical energy, which is later released through cellular respiration to power the activity of the organism.

Therefore, This is the equation for photosynthesis whereby, in the presence of light energy from the Sun and chlorophyll, plants synthesize glucose from carbon dioxide and water.
