Answer:
<h3>SQL injection attacks allow attackers to spoof identity, tamper with existing data, cause repudiation issues such as voiding transactions or changing balances, allow the complete disclosure of all data on the system, destroy the data or make it otherwise unavailable, and become administrators of the database server.</h3>

I would say its B
Because Qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. They do not involve measurements or numbers. For instance, colors, shapes, and textures of objects are all qualitative observations. so its using your 5 senses
2,16·10²⁴ = 21,6·10²³
---------------------------
6,02·10²³ atoms ------ 1 mole of Ag
21,6·10²³ atoms ------ X
X = 21,6·10²³/<span>6,02·10²³
<u>X = 3,588</u> moles of silver

The reaction is 2O₃(g) --> 3O₂ (g) ΔH = -300 kJ/mol
Answer:
c
Explanation:
In the molecule of ozone, 3 oxygens are bonded, and, because each one needs to share two pairs of electrons, these 2 bonds are something between a simple and a double bond.
In the reaction of the transformation of the ozone to oxygen gas, these bonds are broken, and a double bond is formed between two oxygen atoms. The sum of the energy of the broken and the formation of the bond is the enthalpy variation of the reaction.
To break a bond, energy must be added to the system, so it's an endothermic reaction and energy is positive, so the formation is exothermic and the energy is negative. Because there're 2 ozone molecules, 4 bonds will be broken, and because there are 3 oxygen molecules, 3 bonds will be formed:
4*E - 3*500 = -300
4E = -300 + 1500
4E = 1200
E = 300 kJ/mol
So, each O3 bond has 300 kJ/mol as an average energy.
Answer:
With the use of same chemicals, same gas will be produced while the use of different chemicals, different gases will be produced.
Explanation:
The same gas was produced in each assignment if the same chemicals are mixed with each other while different gases were produced in each assignment when different chemicals are allowed to mix. If every time, same chemicals and same concentration of chemicals are mixed together, the result will be the same means production of same gas but if different chemicals are allowed to mix, then the product will be the production of different gases.
