I believe the correct answer to this question is:
“Mixtures”
By definition, mixtures are combination of substances
which are not really chemically combined and hence separable by physical means.
There are two types of mixtures, homogeneous and heterogeneous, both are also
separable by physical means.
<span>This is as opposed to Compounds which are chemically
bonded and cannot be separated by physical means.</span>
Answer:
Na⁺ and HCO⁻₃
Explanation:
When baking soda is dissolve in water it fully ionized into positive and negative ions.
NaHCO₃ + H₂O → Na⁺ + HCO⁻₃
The Na⁺ than react with OH⁻ of water and produced NaOH while HCO⁻₃ react with H⁺ and produce H₂CO₃. This carbonic acid than break to produced carbon dioxide and water.
H₂CO₃ → H₂O + CO₂
Properties of baking soda:
It is odorless compound.
It is solid at room temperature.
It is used in medicine to cure the acidity of stomach.
It is used to make baking powder.
Answer: 12 ( answer not among the option)
Explanation:
From the equation of reaction; P4O10+ H2O -----> H3PO4, it is unbalanced.
One can only get the exact number of ''Hydrogen atom'' if it is well balanced.
Adding '4' to H3PO4 on the RHS and '6' to H2O on LHS of the equation would give a balanced equation such as;
P4O10 + 6H2O -----> 4 H3PO4
Therefore the number of hydrogen atoms found on the reactant is 12.
1. 5 electrons.
- Therefore, the 3d subshells blanks will be like this:
- ↑ ↑ ↑ ↑ ↑
2. 6 electrons.
- The 3d subshells blanks will be:
- ↑↓ ↑ ↑ ↑ ↑
3. 7 electrons.
- The 3d subshells blanks will be:
- ↑↓ ↑↓ ↑ ↑ ↑
Hope you could understand.
If you have any query, feel free to ask.
Not increases it DECREASES because the gas will have too much energy to dissolve in the solution
