That table salt has a high melting point and mercury's melting point is low.
A solution is a homogenous mixture meaning it has a uniform appearance throughout. (example: salt water)
heterogeneous mixture is visibly composed of different things. (example: chicken noodle soup)
Answer:
Total number of water molecules produced after the reaction is 1.956×10^22 molecules of water.
Explanation:
By the reaction
H2+ 1/2 O2 → H2O
Moles of O2 = 5.2\32
⇒1 mole of O2 produce 1 mole of H2O
1 mole O2 will produce 2 mole of H2O
Therefore, 5.2\32 mole will produce 
⇒ Molecules of H2O will be
= 
= 1.956×10^22 moleculesof H2O.
Answer:
1gram of water
Explanation:
First balance the equation
Ch4+2O2>CO2+2H2O
Ratio is 1:2
500×10-3what about 2?
500×10-3×2=1g
1g of water
Answer:
Change in molarity, temperature, volume/pressure depending on the conditions given
Explanation:
It really depends on the type of a reaction, however, we may apply general trends and see every possibility:
- if we increase the concentration of products, then, according to the principle of Le Chatelier, the equilibrium will shift toward the formation of products;
- if we have an endothermic reaction, increasing heat will lead a shift to the right and toward formation of products, since heat might be considered a reactant as well;
- if we have an exothermic reaction, removing heat/decreasing temperature will lead to an increase in products, as we're removing one of our products, heat, and system will try to rebuild the amount of heat lost forming the other products as a result as well;
- if we have gaseous substances in a reaction, an increase in pressure will shift the equilibrium to the right if we have a greater amount in moles of reactant gases compared to products, this is also known as a decrease in volume;
- if we have gaseous substances in a reaction, a decrease in pressure will shift the equilibrium to the right if we have a greater amount in moles of product gases compared to reactants, this is also known as an increase in volume.
