Answer:
6CIO2 + 3H2O = 5HCIO3 + HCI
Explanation:
The 2 in CIO2 is tiny, the 2 in H2O is tiny, and the 3 in HCIO is tiny.
D. Because convection is the transfer of heat and because the heat from the cup was transferred on to the table it has to be d :)
Answer:
The answer is 0.844/10 minutes
Explanation:
You have an enzyme that catalizes a reaction which gives a product that can be quantified by an absorbance measurement. The more reaction time, the more product quantity and higher absorbance.
The rate of the reaction is the change in products quantity per time unit. As you are using the absorbance as a measure of the product quantity, you can calculate the rate as the change in absorbance (ΔA) per time (in minutes) as follows:
rate= ΔA/time
rate= (final absorbance - initial absorbance) /minutes
rate= (0.444-0.022)/5 min
rate= 0.422/5 min
In 10 minutes will be :
rate= 0.844/10 min
Commonly, a rate is the relation between two quantities measured in different units. For example, the speed of a car is the change in meters (traveled distance) per time (m/s or km/h). For an enzyme, is the same (quantity of product/time).
the answer is the last one :All of these
Answer:
Explanation:
First we find the Molecular weight of CaCl2
looking at the periodic table the MW of Ca is 40.078 and Cl is 35.453 and the ratio of ca to cl is 1:2 so we multiply cl by 2 which is 35.453*2=70.906
we add them together: 40.078 + 70.906 = 110.984 g/mol
now:
* 3.45 mol
the mol cancels out and we left with 3.45 * 110.984 grams = 382.89 grams
