Answer:
chemical
Explanation:
The trapped carbon dioxide makes the dough rise, and the alcohol evaporates during the baking process. This is an irreversible chemical change, because by consuming the sugar, the yeast has created new substances
Answer:
A. CaO
Explanation:
Reactant are the species that take part in and also undergoes the reaction to form species which are known as products.
Symbolic representation of the chemical reaction with the help of the formulas and symbols is known as chemical equation. In the chemical equation, reactants are written at left-hand side as well as products are expressed or written on right-hand side. The coefficients which are written before the formulas or the symbols are known as stoichiometric numbers.
Thus, in the reaction shown below:-
<u>Thus, The product of the reaction is:- CaO</u>
Answer: I'm thinking it should be either stay the same or decrease
Explanation: If the size is increasing then the sample should not increase but decrease or stay the same. Mainly the sample would do the opposite of what the size is doing
Answer: A 59.5 degree celcius
The equation that we will use to solve this problem is :
PV = nRT where:
P is the pressure of gas = 1.8 atm
V is the volume of gas = 18.2 liters
n is the number of moles of gas = 1.2 moles
R is the gas constant = 0.0821
T is the temperature required (calculated in kelvin)
Using these values to substitute in the equation, we find that:
(1.8)(18.2) = (1.2)(0.0821)(T)
T = 332.5 degree kelvin
The last step is to convert the degree kelvin into degree celcius:
T = 332.5 - 273 = 59.5 degree celcius
