Answer:
Evidence of chemical change is color change, smell,new matter created, gas created or heat or light being created.
Explanation:
Answer:
Depends on the reaction.
Explanation:
Hello,
In this case, the answer is depends on the reaction since the ratios between the rates of both consumption and formation depend upon the stoichiometric coefficients in the chemical reaction. For instance, for the reaction:
A -> 2B
The relationship is:
Therefore, we can see that the rate of consumption of A half the rate of formation of B, but is we consider the following chemical reaction:
2A -> B
The relationship is:
Therefore we can see that the rate of consumption of A doubles the rate of consumption of B.
Best regards.
Answer:
The initial pressure was 25.2 Pa.
Explanation:
According to the Gay-Lussac's Law, the pressure of given amount of gas is directly proportional to the temperature in kelvin while volume is kept constant.
Formula:
P₁/T₁ =P₂/T₂
P₁ = Initial pressure
T₁ = Initial temperature
P₂ = Final pressure
T₂ = Final temperature
Given data:
T₁ = 87 K
T₂ = 62.25 K
P₂ = 18 Pa
P₁ = ?
Now we will put the values in formula,
P₁/T₁ = P₂/T₂
P₁ = P₂/T₂×T₁
P₁ = (18 Pa / 62.25 K) × 87 K
P₁ = 0.2892 Pa/k × 87 K
P₁ = 25.2 Pa
The initial pressure was 25.2 Pa.
By gaining an electron (perhaps via beta particle). The H+ ion needs another electron to remove its positive charge.
Answer:
Explanation:
This is because too much heat can make it difficult for the body to regulate its temperature. Failing to treat this problem early enough can cause damage to the brain and other organs of the body. Since air conditioners reduce the temperature of the air, they can be helpful in preventing heat strokes.
