its d because it all has to be balanced
Answer:
1.slimy feel
2.corrosive
Explanation:
hey friend hope it's help you...
The answer is B. The complete equation is C6H12O6 + 6O2 -->6H2O + 6CO2 + energy. So we can know that A and C and D is right. For B, the reaction release energy so it is exothermic reaction.
<u><em>Answer:</em></u>
- The correct option is C.
- Formation of a precipitate
<u><em>Explanation:</em></u>
During a chemical reaction, new substances are formed known as a products, mostly reaction occur and their product is obtained as precipitates.
<u><em>Example</em></u>
Arylidene-2-thiobarbituric acid is obtained as precipitates when aldehyde and thiobarbituric acid react to each other.
melting of a substance
It is just indication of physical changes, like melting of ice, composition remained same as before.
boiling of a substance
It is just indication of physical changes, like boiling of water into vapors, composition remained same as before.
freezing of a substance
It is just indication of physical changes, like freezing of water into ice, composition remained same as before
<u>Answer:</u>
<u>For a:</u> The balanced equation is ![2S(s)+3O_2(g)\rightarrow 2SO_3(g)](https://tex.z-dn.net/?f=2S%28s%29%2B3O_2%28g%29%5Crightarrow%202SO_3%28g%29)
<u>For c:</u> The balanced equation is ![2NaOH(s)+H_2SO_4(aq)\rightarrow Na_2SO_4(aq)+2H_2O(l)](https://tex.z-dn.net/?f=2NaOH%28s%29%2BH_2SO_4%28aq%29%5Crightarrow%20Na_2SO_4%28aq%29%2B2H_2O%28l%29)
<u>Explanation:</u>
A balanced chemical equation is one where all the individual atoms are equal on both sides of the reaction. It follows the law of conservation of mass.
The given unbalanced equation follows:
![S(s)+O_2(g)\rightarrow SO_3(g)](https://tex.z-dn.net/?f=S%28s%29%2BO_2%28g%29%5Crightarrow%20SO_3%28g%29)
To balance the equation, we must balance the atoms by adding 2 infront of both
and
and 3 in front of ![O_2](https://tex.z-dn.net/?f=O_2)
For the balanced chemical equation:
![2S(s)+3O_2(g)\rightarrow 2SO_3(g)](https://tex.z-dn.net/?f=2S%28s%29%2B3O_2%28g%29%5Crightarrow%202SO_3%28g%29)
The given balanced equation follows:
![2Al(s)+3Cl_2(g)\rightarrow 2AlCl_3(s)](https://tex.z-dn.net/?f=2Al%28s%29%2B3Cl_2%28g%29%5Crightarrow%202AlCl_3%28s%29)
The given equation is already balanced.
The given unbalanced equation follows:
![2NaOH(s)+H_2SO_4(aq)\rightarrow Na_2SO_4(aq)+H_2O(l)](https://tex.z-dn.net/?f=2NaOH%28s%29%2BH_2SO_4%28aq%29%5Crightarrow%20Na_2SO_4%28aq%29%2BH_2O%28l%29)
To balance the equation, we must balance the atoms by adding 2 infront of ![H_2O(l)](https://tex.z-dn.net/?f=H_2O%28l%29)
For the balanced chemical equation:
The given balanced equation follows:
![C_3H_8(g)+5O_2(g)\rightarrow 3CO_2(g)+4H_2O(g)](https://tex.z-dn.net/?f=C_3H_8%28g%29%2B5O_2%28g%29%5Crightarrow%203CO_2%28g%29%2B4H_2O%28g%29)
The given equation is already balanced.
